[0002] Manganese silicon alloy waste slag is the main solid waste of ferroalloy smelting. A large amount of manganese silicon alloy waste slag formed during the ferroalloy smelting process is usually treated by stacking and landfilling. This treatment method not only occupies land resources, but also pollutes soil and groundwater. With the continuous expansion of the scale of the ferroalloy smelting industry, the output of manganese silicon alloy waste slag is also increasing. If the above-mentioned stacking and landfilling method is still used, it will inevitably increase the degree of environmental pollution, which is not conducive to controlling smelting industrial pollution. Considering that manganese silicon alloy waste slag can be recycled to make inorganic insulation cotton such as rock mineral wool, it is of great significance to building materials such as insulation cotton. Using manganese silicon alloy waste slag to make insulation cotton has become an important direction for waste slag recycling.

[0051] See also Figure 1 , is a schematic flow chart of a method for preparing rock wool based on manganese-silicon alloy slag provided by an embodiment of the present invention. The method for preparing rock wool based on manganese-silicon alloy slag comprises:

[0052] Step S1, performing dehydration pretreatment and screening pretreatment on the manganese silicon alloy slag to obtain a plurality of manganese silicon alloy granular slag collections;

[0053] Step S2, based on the heating temperature distribution characteristics inside the furnace, selecting at least one manganese-silicon alloy granular slag set to heat and melt; based on the melting change characteristics of the granular slag inside the furnace, adjusting the addition operation of the manganese-silicon alloy granular slag set or the flux addition operation to the furnace;

[0054] Step S3, after heat preservation treatment is performed on the manganese-silicon alloy melt in the furnace, the manganese-silicon alloy melt is centrifuged and shaped to obtain a fiber bundle;

[0055] Step S4, after surface modification treatment of the fiber bundle, the fiber bundle is transported to a cotton collector to form rock mineral wool; based on the output state characteristics of the rock mineral wool of the cotton collector, the collection and packaging operation of the rock mineral wool is adjusted.

[0056] The method for preparing rock mineral wool based on manganese silicon alloy slag dehydrates and screens the manganese silicon alloy slag into a plurality of manganese silicon alloy granular slag collections, and classifies the manganese silicon alloy waste slag into morphological structures, so as to facilitate heating and melting the corresponding granular slag collections in different furnace heating scenarios; based on the melting change characteristics of the granular slag inside the furnace, the manganese silicon alloy adding operation or flux adding operation to the furnace is adjusted to increase the output of molten manganese silicon alloy; the manganese silicon alloy melt in the furnace is subjected to insulation treatment, centrifugal treatment and shaping treatment to obtain fiber bundles; the fiber bundles are subjected to surface modification treatment and transported to a cotton collector to form a rock ore surface; and based on the rock mineral wool output state characteristics of the cotton collector, the collection and packaging operation of the rock mineral wool is adjusted, and by selecting a granular slag collection matching the heating temperature state inside the furnace for heating and melting according to the slag body morphology and structure of the manganese silicon alloy slag, the granular slag put into the furnace is ensured to be melted efficiently and quickly, thereby improving the melting efficiency of the manganese silicon alloy waste slag and the output and quality of the rock mineral wool.

[0057] Preferably, in step S1, the manganese-silicon alloy slag is subjected to dehydration pretreatment and screening pretreatment to obtain a plurality of manganese-silicon alloy granular slag sets, including:

[0058] Infrared detection and identification are performed on the silico-manganese alloy slag in the dehydration pretreatment process to obtain moisture content change data of the silico-manganese alloy slag; wherein the moisture content change data include the moisture content change data of different slag body areas in the silico-manganese alloy slag over time; based on the moisture content change data, the hot air flow conveying parameters of the silico-manganese alloy slag in the dehydration pretreatment process are adjusted to obtain dry silico-manganese alloy slag; wherein the hot air flow conveying parameters include the hot air flow conveying flow rate and / or the hot air flow conveying direction;

[0059] The manganese silicon alloy dry slag is crushed and screened for pretreatment to obtain a plurality of manganese silicon alloy granular slag sets; wherein each manganese silicon alloy granular slag set has a corresponding particle size distribution range, and the particle size distribution ranges of any two different manganese silicon alloy granular slag sets do not overlap each other.

[0060] Manganese silicon alloy slag is a water-containing waste slag produced during the ferroalloy smelting process, and its main component is manganese silicon alloy material. The use of manganese silicon alloy slag to make rock wool requires pre-dehydration treatment. Only when the moisture content of the manganese silicon alloy slag is reduced to below a certain threshold can the subsequent furnace ensure the rapid and efficient melting treatment of the manganese silicon alloy. If the moisture content of the manganese silicon alloy slag is high, more energy is required for melting treatment inside the furnace, and the moisture in it will react with coke to form carbon monoxide and be discharged with the tail gas, resulting in waste of heat energy. In order to reduce the waste of heat energy inside the furnace and improve the melting conversion efficiency of manganese silicon alloy slag, infrared detection is first performed on the manganese silicon alloy slag to obtain the moisture content change data of the manganese silicon alloy slag during the dehydration pretreatment process, so as to accurately calibrate the moisture content of different slag areas in the manganese silicon alloy slag over time. Based on the moisture content change data of the manganese silicon alloy slag, the location of the slag area with a higher moisture content inside the manganese silicon alloy slag and the size of the slag area are identified, so as to adaptively adjust the hot air flow rate (hot air flow volume per unit time) and / or hot air flow direction of the manganese silicon alloy slag during the dehydration pretreatment process, so that the slag area with a higher moisture content inside the manganese silicon alloy slag can obtain hot air flow drying at a higher flow rate, and the slag area with a higher moisture content inside the manganese silicon alloy slag can be aligned to obtain hot air flow drying. In addition, the manganese silicon alloy slag is subjected to dehydration pretreatment to obtain manganese silicon alloy dry slag, which contains a large amount of granular slag with different particle sizes. If all the manganese silicon alloy dry slag is directly put into the furnace for heating and melting treatment, it cannot be guaranteed that all the granular slag can be heated evenly, which reduces the heating and melting efficiency of the manganese silicon alloy dry slag. For this purpose, the silicon-manganese alloy dry slag is crushed and screened for pretreatment to obtain several manganese-silicon alloy granular slag sets, so that different manganese-silicon alloy granular slag sets have different particle size distribution ranges, and the particle sizes of all granular slags under the same manganese-silicon alloy granular slag set are similar. In this way, the same manganese-silicon alloy granular slag is put into the furnace to ensure that all granular slags can be evenly heated inside the furnace and all converted into a molten state in a relatively short time.

[0061] Preferably, in step S2, based on the heating temperature distribution characteristics inside the furnace, at least one manganese-silicon alloy granular slag set is selected for heating and melting; based on the melting change characteristics of the granular slag inside the furnace, the operation of adding the manganese-silicon alloy granular slag set or the operation of adding flux to the furnace is adjusted, including:

[0062] Based on the spatial distribution characteristics of the heating temperature inside the furnace, the heating efficiency inside the furnace is estimated; wherein the heating efficiency refers to the amount of heat transferred to the manganese-silicon alloy particles per unit volume per unit time inside the furnace; based on the heating efficiency, the particle size range of the manganese-silicon alloy particles currently matched for heating in the furnace is determined, so as to select at least one manganese-silicon alloy particle slag set for heating and melting;

[0063] Based on the volume change characteristics of the granular slag in a molten state inside the furnace, it is judged whether an abnormal melting transformation event occurs in the granular slag inside the furnace; if an abnormal melting transformation event occurs, the amount of flux added to the furnace is increased; if no abnormal melting transformation event occurs, the volume of a set of manganese silicon alloy granular slag with a matching particle size range added to the furnace is increased.

[0064] The furnace is used to heat and convert the manganese-silicon alloy granular slag into a molten state, and the heating temperature state inside the furnace directly affects the efficiency of converting the manganese-silicon alloy granular slag into a molten state. Generally speaking, the higher the heating temperature inside the furnace, the larger the particle size of the manganese-silicon alloy granular slag allowed to be heated and melted. In order to enable the furnace to efficiently heat and melt the manganese-silicon alloy granular slag put into it, it is necessary to determine the particle size of the manganese-silicon alloy particles that are heated by the current heat inside the furnace according to the heating temperature state inside the furnace. To this end, the global heating temperature inside the furnace is first detected to obtain the heating temperature spatial distribution characteristics inside the furnace (such as the heating temperature size distribution characteristics of all regions under the furnace) and combined with the specific heat capacity of the manganese-silicon alloy particles, so as to estimate the amount of heat transferred to the unit volume of manganese-silicon alloy particles in the furnace per unit time, so as to match and compare all the above-mentioned manganese-silicon alloy granular slag sets, determine at least one manganese-silicon alloy granular slag set suitable for the current heating environment conditions inside the furnace, and put the above-mentioned at least one manganese-silicon alloy granular slag set into the furnace for heating and melting. In addition, based on the volume change characteristics of the granular slag in a molten state inside the furnace, it is determined whether all the granular slag inside the furnace is converted into a molten state within a preset time; if not, it is judged that an abnormal melting conversion event has occurred inside the furnace, and the amount of flux added to the furnace is increased at this time to increase the melting reaction rate of the manganese silicon alloy inside the furnace; if so, it is judged that no abnormal melting conversion event has occurred inside the furnace, and a volume of a manganese silicon alloy granular slag set with a matching particle size range is added to the furnace, so that the furnace can convert more manganese silicon alloy granular slag into a molten state under the current heating conditions, thereby providing sufficient raw material supply for subsequent production of fiber bundles.

[0065] Preferably, in step S3, after the manganese-silicon alloy melt in the furnace is subjected to heat preservation treatment, the manganese-silicon alloy melt is subjected to centrifugal treatment and shaping treatment to obtain a fiber bundle, comprising:

[0066] Based on the tail gas output state of the furnace, the tail gas outputted from the furnace is recovered and pressurized, and then transmitted back to the furnace to perform heat preservation treatment on the manganese silicon alloy melt;

[0067] The manganese silicon alloy melt is transported to a centrifuge for fiber drawing, and the fiber filaments obtained by the fiber drawing are cooled and shaped to obtain a fiber bundle.

[0068] The furnace will inevitably produce tail gas during the process of heating and melting the manganese silicon alloy granular slag. These tail gases usually carry a lot of heat. If these tail gases are directly discharged to the external environment, it will cause a huge waste of heat. At the same time, after the furnace heats the manganese silicon alloy granular slag and converts it into a molten state, it is necessary to maintain the temperature inside the furnace for a certain period of time, so as to ensure that the manganese silicon alloy melt is normally centrifugally stretched into a fiber shape later. In order to reduce the energy consumption of the furnace, based on the tail gas output state of the furnace, the tail gas output by the furnace is recovered and pressurized. For example, according to the tail gas output flow rate of the furnace, the negative pressure adsorption recovery intensity of the tail gas output by the furnace is adjusted, the output tail gas is efficiently and thoroughly recovered, and it is judged whether the actual pressure of the recovered tail gas exceeds the preset pressure threshold. If so, the recovered tail gas is directly transmitted back to the inside of the furnace; if not, the recovered tail gas is first pressurized and then transmitted back to the inside of the furnace, so as to fully recycle the tail gas of the furnace and save the energy consumption of the furnace. In addition, after the manganese-silicon alloy melt is treated by heat preservation, it is directly transported to a centrifuge for fiber drawing, and the fiber filaments obtained by the fiber drawing are cooled and formed to obtain fiber bundles, thereby converting the manganese-silicon alloy into inorganic fiber bundles.

[0069] Preferably, in step S4, after the fiber bundle is subjected to surface modification treatment, it is transported to a cotton collector to form rock mineral wool; based on the output state characteristics of the rock mineral wool of the cotton collector, the collection and packaging operation of the rock mineral wool is adjusted, including:

[0070] Spraying a dust-proof agent on the surface of the fiber bundle, adjusting the dust-proof agent spraying operation parameters on the surface of the fiber bundle based on the adhesion state characteristics of the dust-proof agent on the surface of the fiber bundle, and transporting the fiber bundle sprayed with the dust-proof agent to the cotton collecting machine to form rock mineral wool; wherein the dust-proof agent spraying operation parameters include at least one of the dust-proof agent spraying flow rate, spraying direction and spraying duration;

[0071] Based on the changing characteristics of the negative pressure suction and precipitation output of the rock mineral wool by the cotton collector, determine whether the rock mineral wool currently precipitated and output by the cotton collector meets the preset weight requirement; if so, directly collect and pack the rock mineral wool currently precipitated and output; if not, suspend the collection and packing operation of the rock mineral wool currently precipitated and output.

[0072] The surface of the fiber bundle obtained after centrifugal drawing and cooling and shaping is in an exposed state. Considering that rock mineral wool is usually used in special occasions, in order to avoid the external environment affecting the performance of the rock mineral surface, the fiber bundle needs to be surface modified. Specifically, the dust repellent is sprayed on the surface of the fiber bundle. Based on the characteristics of the attachment state of the dust repellent on the surface of the fiber bundle, at least one of the spraying flow rate, spraying direction and spraying duration of the dust repellent on the surface of the fiber bundle is adjusted, and the fiber bundle sprayed with the dust repellent is transported to the cotton collector to form rock mineral wool. In this way, the global surface of the fiber bundle can be evenly covered with dust repellent to avoid the rock mineral wool from adsorbing dust on the surface in actual application and affecting normal use. There is also a change in the output volume of the negative pressure suction precipitation of the rock mineral wool by the cotton collector, which determines whether the rock mineral wool currently precipitated and output by the cotton collector meets the preset weight requirement (i.e., the preset weight range requirement). Only when the preset weight requirement is met, the rock mineral wool currently precipitated and output is directly collected and packaged, thereby ensuring that the rock mineral wool collected and packaged has sufficient weight and improving the overall mechanical strength of the rock mineral wool.

[0073] See also Figure 2 , is a schematic diagram of a framework of a rock wool preparation system based on manganese silicon alloy slag provided by an embodiment of the present invention. The rock wool preparation system based on manganese silicon alloy slag comprises:

[0074] A dehydration and screening processing module is used to perform dehydration pretreatment and screening pretreatment on the manganese silicon alloy slag to obtain a plurality of manganese silicon alloy granular slag sets;

[0075] A granular slag set selection module, used to select at least one manganese-silicon alloy granular slag set for heating and melting based on the heating temperature distribution characteristics inside the furnace;

[0085] Manganese silicon alloy slag is a water-containing waste slag produced during the ferroalloy smelting process, and its main component is manganese silicon alloy material. The use of manganese silicon alloy slag to make rock wool requires pre-dehydration treatment. Only when the moisture content of the manganese silicon alloy slag is reduced to below a certain threshold can the subsequent furnace ensure the rapid and efficient melting treatment of the manganese silicon alloy. If the moisture content of the manganese silicon alloy slag is high, more energy is required for melting treatment inside the furnace, and the moisture in it will react with coke to form carbon monoxide and be discharged with the tail gas, resulting in waste of heat energy. In order to reduce the waste of heat energy inside the furnace and improve the melting conversion efficiency of manganese silicon alloy slag, infrared detection is first performed on the manganese silicon alloy slag to obtain the moisture content change data of the manganese silicon alloy slag during the dehydration pretreatment process, so as to accurately calibrate the moisture content of different slag areas in the manganese silicon alloy slag over time. Based on the moisture content change data of the manganese silicon alloy slag, the location of the slag area with a higher moisture content inside the manganese silicon alloy slag and the size of the slag area are identified, so as to adaptively adjust the hot air flow rate (hot air flow volume per unit time) and / or hot air flow direction of the manganese silicon alloy slag during the dehydration pretreatment process, so that the slag area with a higher moisture content inside the manganese silicon alloy slag can obtain hot air flow drying at a higher flow rate, and the slag area with a higher moisture content inside the manganese silicon alloy slag can be aligned to obtain hot air flow drying. In addition, the manganese silicon alloy slag is subjected to dehydration pretreatment to obtain manganese silicon alloy dry slag, which contains a large amount of granular slag with different particle sizes. If all the manganese silicon alloy dry slag is directly put into the furnace for heating and melting treatment, it cannot be guaranteed that all the granular slag can be heated evenly, which reduces the heating and melting efficiency of the manganese silicon alloy dry slag. For this purpose, the silicon-manganese alloy dry slag is crushed and screened for pretreatment to obtain several manganese-silicon alloy granular slag sets, so that different manganese-silicon alloy granular slag sets have different particle size distribution ranges, and the particle sizes of all granular slags under the same manganese-silicon alloy granular slag set are similar. In this way, the same manganese-silicon alloy granular slag is put into the furnace to ensure that all granular slags can be evenly heated inside the furnace and all converted into a molten state in a relatively short time.

[0086] Preferably, the granular slag set selection module is used to select at least one manganese-silicon alloy granular slag set for heating and melting based on the heating temperature distribution characteristics inside the furnace, including:

[0087] Based on the spatial distribution characteristics of the heating temperature inside the furnace, the heating efficiency inside the furnace is estimated; wherein the heating efficiency refers to the amount of heat transferred to the manganese-silicon alloy particles per unit volume per unit time inside the furnace; based on the heating efficiency, the particle size range of the manganese-silicon alloy particles currently matched for heating in the furnace is determined, so as to select at least one manganese-silicon alloy particle slag set for heating and melting;

[0088] The granular slag / flux addition adjustment module is used to adjust the manganese silicon alloy granular slag set addition operation or flux addition operation to the furnace based on the granular slag melting change characteristics inside the furnace, including:

[0089] Based on the volume change characteristics of the granular slag in a molten state inside the furnace, it is judged whether an abnormal melting transformation event occurs in the granular slag inside the furnace; if an abnormal melting transformation event occurs, the amount of flux added to the furnace is increased; if no abnormal melting transformation event occurs, the volume of a set of manganese silicon alloy granular slag with a matching particle size range added to the furnace is increased.

[0090] The furnace is used to heat and convert the manganese-silicon alloy granular slag into a molten state, and the heating temperature state inside the furnace directly affects the efficiency of converting the manganese-silicon alloy granular slag into a molten state. Generally speaking, the higher the heating temperature inside the furnace, the larger the particle size of the manganese-silicon alloy granular slag allowed to be heated and melted. In order to enable the furnace to efficiently heat and melt the manganese-silicon alloy granular slag put into it, it is necessary to determine the particle size of the manganese-silicon alloy particles that are heated by the current heat inside the furnace according to the heating temperature state inside the furnace. To this end, the global heating temperature inside the furnace is first detected to obtain the heating temperature spatial distribution characteristics inside the furnace (such as the heating temperature size distribution characteristics of all regions under the furnace) and combined with the specific heat capacity of the manganese-silicon alloy particles, so as to estimate the amount of heat transferred to the unit volume of manganese-silicon alloy particles in the furnace per unit time, so as to match and compare all the above-mentioned manganese-silicon alloy granular slag sets, determine at least one manganese-silicon alloy granular slag set suitable for the current heating environment conditions inside the furnace, and put the above-mentioned at least one manganese-silicon alloy granular slag set into the furnace for heating and melting. In addition, based on the volume change characteristics of the granular slag in a molten state inside the furnace, it is determined whether all the granular slag inside the furnace is converted into a molten state within a preset time; if not, it is judged that an abnormal melting conversion event has occurred inside the furnace, and the amount of flux added to the furnace is increased at this time to increase the melting reaction rate of the manganese silicon alloy inside the furnace; if so, it is judged that no abnormal melting conversion event has occurred inside the furnace, and a volume of a manganese silicon alloy granular slag set with a matching particle size range is added to the furnace, so that the furnace can convert more manganese silicon alloy granular slag into a molten state under the current heating conditions, thereby providing sufficient raw material supply for subsequent production of fiber bundles.

[0091] Preferably, the heat preservation treatment module is used to perform heat preservation treatment on the manganese silicon alloy melt inside the furnace, comprising:

[0092] Based on the tail gas output state of the furnace, the tail gas outputted from the furnace is recovered and pressurized, and then transmitted back to the furnace to perform heat preservation treatment on the manganese silicon alloy melt;

[0093] The centrifugal and shaping treatment module is used to centrifuge and shape the manganese silicon alloy melt to obtain a fiber bundle, including:

[0094] The manganese silicon alloy melt is transported to a centrifuge for fiber drawing, and the fiber filaments obtained by the fiber drawing are cooled and shaped to obtain a fiber bundle.

[0095] The furnace will inevitably produce tail gas during the process of heating and melting the manganese silicon alloy granular slag. These tail gases usually carry a lot of heat. If these tail gases are directly discharged to the external environment, it will cause a huge waste of heat. At the same time, after the furnace heats the manganese silicon alloy granular slag and converts it into a molten state, it is necessary to maintain the temperature inside the furnace for a certain period of time, so as to ensure that the manganese silicon alloy melt is normally centrifugally stretched into a fiber shape later. In order to reduce the energy consumption of the furnace, based on the tail gas output state of the furnace, the tail gas output by the furnace is recovered and pressurized. For example, according to the tail gas output flow rate of the furnace, the negative pressure adsorption recovery intensity of the tail gas output by the furnace is adjusted, the output tail gas is efficiently and thoroughly recovered, and it is judged whether the actual pressure of the recovered tail gas exceeds the preset pressure threshold. If so, the recovered tail gas is directly transmitted back to the inside of the furnace; if not, the recovered tail gas is first pressurized and then transmitted back to the inside of the furnace, so as to fully recycle the tail gas of the furnace and save the energy consumption of the furnace. In addition, after the manganese-silicon alloy melt is treated by heat preservation, it is directly transported to a centrifuge for fiber drawing, and the fiber filaments obtained by the fiber drawing are cooled and formed to obtain fiber bundles, thereby converting the manganese-silicon alloy into inorganic fiber bundles.

[0096] Preferably, the surface modification treatment module is used to perform surface modification treatment on the fiber bundles and then transport them to the cotton collection machine to form rock mineral wool, comprising:

[0097] Spraying a dust-proof agent on the surface of the fiber bundle, adjusting the dust-proof agent spraying operation parameters on the surface of the fiber bundle based on the adhesion state characteristics of the dust-proof agent on the surface of the fiber bundle, and transporting the fiber bundle sprayed with the dust-proof agent to the cotton collecting machine to form rock mineral wool; wherein the dust-proof agent spraying operation parameters include at least one of the dust-proof agent spraying flow rate, spraying direction and spraying duration;

[0098] The collection and packaging operation module is used to adjust the collection and packaging operation of rock and mineral wool based on the output state characteristics of the rock and mineral wool collector, including:

[0099] Based on the changing characteristics of the negative pressure suction and precipitation output of the rock mineral wool by the cotton collector, determine whether the rock mineral wool currently precipitated and output by the cotton collector meets the preset weight requirement; if so, directly collect and pack the rock mineral wool currently precipitated and output; if not, suspend the collection and packing operation of the rock mineral wool currently precipitated and output.

[0100] The surface of the fiber bundle obtained after centrifugal drawing and cooling and shaping is in an exposed state. Considering that rock mineral wool is usually used in special occasions, in order to avoid the external environment affecting the performance of the rock mineral surface, the fiber bundle needs to be surface modified. Specifically, the dust repellent is sprayed on the surface of the fiber bundle. Based on the characteristics of the attachment state of the dust repellent on the surface of the fiber bundle, at least one of the spraying flow rate, spraying direction and spraying duration of the dust repellent on the surface of the fiber bundle is adjusted, and the fiber bundle sprayed with the dust repellent is transported to the cotton collector to form rock mineral wool. In this way, the global surface of the fiber bundle can be evenly covered with dust repellent to avoid the rock mineral wool from adsorbing dust on the surface in actual application and affecting normal use. There is also a change in the output volume of the negative pressure suction precipitation of the rock mineral wool by the cotton collector, which determines whether the rock mineral wool currently precipitated and output by the cotton collector meets the preset weight requirement (i.e., the preset weight range requirement). Only when the preset weight requirement is met, the rock mineral wool currently precipitated and output is directly collected and packaged, thereby ensuring that the rock mineral wool collected and packaged has sufficient weight and improving the overall mechanical strength of the rock mineral wool.

[0101] It can be seen from the contents of the above embodiments that the method and system for preparing rock mineral wool based on manganese silicon alloy slag dehydrates and screens the manganese silicon alloy slag into several manganese silicon alloy granular slag collections, and classifies the manganese silicon alloy waste slag into morphological structures, so as to facilitate heating and melting the corresponding granular slag collections in different furnace heating scenarios; based on the melting change characteristics of the granular slag inside the furnace, the manganese silicon alloy addition operation or the flux addition operation to the furnace is adjusted to increase the output of molten manganese silicon alloy; the manganese silicon alloy melt in the furnace is subjected to insulation treatment, centrifugal treatment and shaping treatment to obtain fiber bundles; the fiber bundles are surface modified and transported to the cotton collector to form the rock mineral surface; and based on the rock mineral wool output state characteristics of the cotton collector, the collection and packaging operation of the rock mineral wool is adjusted, and the granular slag collection matching the heating temperature state inside the furnace is selected for heating and melting according to the slag body morphology and structure of the manganese silicon alloy slag, so as to ensure that the granular slag put into the furnace is melted efficiently and quickly, thereby improving the melting efficiency of the manganese silicon alloy waste slag and the output and quality of the rock mineral wool.
