Description

Technical Field

[0001] This utility model belongs to the technical field of ladle feeding equipment, specifically relating to a flat-push alloy feeding device based on a ladle. Background Technology

[0002] The ladle is an important piece of equipment in the steelmaking process. It holds molten steel, and sometimes a certain amount of alloys such as ferrosilicon, ferromanganese, ferrochrome, ferromolybdenum, ferrotitanium, or ferroaluminum need to be added to adjust the steel composition, regulate the temperature, improve the purity of the steel, and optimize the solidification structure. Currently, most steel companies use a combination of manual direct feeding and automatic silo feeding. When the amount of alloy added is relatively small, manual direct feeding is usually used. This method is relatively simple to operate, but the work efficiency is relatively low, the feeding effect is not ideal, and there are certain safety hazards. When the amount of alloy added is relatively large, automatic silo feeding is used. This method is relatively efficient and the feeding effect is more ideal, but the silo structure design is relatively complex, the operation process is relatively cumbersome, and the investment scale and land area are relatively large. Therefore, it is necessary to develop an alloy adding device based on the ladle.

[0003] After searching, three patent documents were found to be most relevant to this utility model technology. The specific contents are described below:

[0004] Patent document CN 200620090793.1 discloses a rotary feeding device for a ladle turning machine. The device includes a hopper, a gate, a feeding pipe, a rotating device, a support, a working platform, a base, a fixed shaft, a cylinder, a piston rod, a slewing bearing seat, and a feeding device. The device is ingeniously designed and can easily and quickly switch the feeding pipe between the standby position and the working position by manual or pneumatic means. When the feeding pipe rotates from the standby position to the working position, it completes the feeding of guiding sand. When it rotates from the working position to the standby position, it makes room for other operations. It has the characteristics of high working efficiency and small footprint. However, the structural design of the device is relatively complex, so the production cost of the device is relatively high.

[0005] Patent document CN 202120052589.5 discloses a ladle tilting scrap steel feeding device. The device includes an electro-hydraulic actuator, a hopper, an intermediate connecting pipe, a chute, a support, a platform, and control lines. The device is ingeniously designed. When the electro-hydraulic actuator moves upward, it causes the hopper to tilt forward on the support. The scrap steel in the hopper falls from the discharge port into the intermediate connecting pipe, and then into the ladle through the chute. This device can achieve the purpose of adding a sufficient amount of scrap steel into the ladle. It has the characteristics of low production cost, fast feeding speed, and energy saving. However, it occupies a relatively large area. Since the device is designed based on the addition of scrap steel, it is only suitable for adding scrap steel into the ladle and not for adding alloys into the ladle.

[0006] Patent document CN 202223285088.5 discloses a ladle feeding device, which includes a platform beam, a hopper, a vibrating feeder, a weighing hopper, an electro-hydraulic slide valve, a feeding chute device, an electro-hydraulic three-way valve, an alloy baking device, a manual feeding device, and a rotating alloy chute device. The device is ingeniously designed. The use of multiple hoppers can achieve the simultaneous feeding of multiple alloys. When a hopper fails, the device can ensure continuous operation. The use of the alloy baking device can bake the alloy, which helps to increase the tapping temperature and avoid the occurrence of intermittent casting. It has the characteristics of high working efficiency and good stability. However, the structural design of the device is relatively complex, so the production cost of the device is relatively high.

[0063] The working principle of the ladle-based flat-push alloy addition device provided by this utility model

[0064] Combination Figure 1 and Figure 2As shown, when the two fourth bodies 401 of the two fourth supports 4 are close enough, the alloy can be piled up in the two third through slots 404. The four eighth protrusions 402 arranged in pairs in front and back can form four walls and prevent the alloy from rolling down from the front and back direction; the two twelfth protrusions 504 on the left and right sides can also form two walls and prevent the alloy from rolling down from the left and right direction; the eleventh protrusion 503 in the middle can prevent the alloy from rolling down from the middle position.

[0065] When the two fourth bodies 401 of the two fourth supports 4 are sufficiently far apart, the alloy located within the two third through slots 404 will be blocked by the two twelfth protrusions 504 and will not be able to move left or right accordingly. It can only be stacked up, but it will be blocked by the two tenth protrusions 502 on the left and right and will not be able to be stacked up. During this period, the alloy can only pass through the second through hole 205 of the second support 2 and fall precisely into the ladle. It can also pass through the slag layer covering the surface of the molten steel and enter the molten steel.

[0066] Because the surface of molten steel is covered with a slag layer of a certain thickness, the alloy must have a certain amount of kinetic energy to overcome the resistance and pass through the slag layer smoothly. The kinetic energy of the alloy mainly comes from the conversion of the alloy's gravitational potential energy. The gravitational potential energy of the alloy depends on the alloy's density, volume, gravitational acceleration, and relative drop height. Since the volume and gravitational acceleration of the alloy are usually fixed values, the gravitational potential energy of the alloy mainly depends on the alloy's density and relative drop height.

[0067] When the gravitational potential energy is constant, the relative drop height of the alloy is negatively correlated with the alloy density. For alloys with relatively low density, a relatively high drop height should be selected to obtain a certain high potential energy, thereby obtaining a larger falling kinetic energy, and thus being able to pass through the slag layer and enter the molten steel smoothly. For alloys with relatively high density, a relatively low drop height can be selected to obtain a certain high potential energy, thereby obtaining a larger falling kinetic energy, and thus being able to pass through the slag layer and enter the molten steel smoothly.

[0068] The method of using the ladle-based flat-push alloy addition device provided by this utility model

[0069] Assuming the two fourth support vehicles are initially positioned far apart, firstly, along the four second through slots 204 of the second support 2, the two fourth support vehicles are brought close together so that the eleventh protrusion 503 of the fifth support 5 can be simultaneously placed on the two fourth bodies 401 of the two fourth supports 4; then, along the eight ninth through holes 704 of the two linear bearings 7, the four connecting rods 10 are moved downwards at a constant speed, and then the alloy is stably stacked within the two third through slots 404, and then, along the eight ninth through holes 704 of the two linear bearings 7, the four connecting rods 10 are moved upwards at a constant speed. The connecting rod 10 is then moved horizontally at a constant speed so that the second support 2 is aligned with the ladle. Then, the four connecting rods 10 are moved downward at a constant speed along the eight ninth through holes 704 of the two linear bearings 7 to select a suitable alloy pouring height. Then, the two fourth support vehicles are moved far apart along the four second through slots 204 of the second support 2. During this time, the alloy piled in the two third through slots 404 will be blocked by the two twelfth protrusions 504 and will pass through the second through holes 205 of the second support 2 and the slag layer of the ladle in turn, and enter the molten steel.

[0070] Supplementary Explanation: The ladle-based flat-push alloy adding device provided by this utility model adopts a symmetrical structure design. The device should be designed and manufactured to match the diameter and height of the ladle. The appropriate alloy adding height mainly depends on the alloy's density. Alloys with relatively low density should be added at a relatively high height, while alloys with relatively high density can be added at a relatively low height, in order to obtain a certain high potential energy and thus smoothly penetrate the slag layer and enter the molten steel. The positional relationship of the two fourth support cars being sufficiently close refers to the distance between them. It should be ensured that the eleventh protrusion 503 can be simultaneously set on the upper surfaces of the two fourth bodies 401 of the two fourth supports 4. At this point, the positional relationship between the two fourth support cars is one of sufficient closeness. The positional relationship of the two fourth support cars being sufficiently far apart refers to the distance between them. The distance should be such that the twelfth protrusion 504 on the left can be positioned at the rightmost end of the fourth body 401 on the left, and the twelfth protrusion 504 on the right can be positioned at the leftmost end of the fourth body 401 on the right. That is, both twelfth protrusions 504 can push the alloy out completely from the two third through slots 404. At this time, the positional relationship between the two fourth support vehicles is a sufficiently far apart positional relationship. The front-to-back length of the second through hole 205 should be slightly greater than the front-to-back length of the third through slot 404, and the left-to-right length of the second through hole 205 should be slightly greater than the distance between the two twelfth protrusions 504, so that all the pushed-out alloy can pass smoothly through the second through hole 205. To simplify the operation, when the four wheels 12 installed on the two fourth supports 4 can simultaneously contact the four sixth protrusions 203 of the second support 2, the two fourth support vehicles are in a sufficiently far apart positional relationship.

[0071] As can be seen from the embodiments, the ladle-based flat-push alloy adding device provided by this utility model can achieve the purpose of smoothly adding alloy into the ladle. This utility model device has the characteristics of low manufacturing cost, simple operation and good use effect.
