Description

Technical Field

[0001] The present invention belongs to the technical field of detection, and particularly relates to a reduction atmosphere detection and adjustment system and an adjustment method for manganese-silicon alloy with high manganese content. Background Art

[0002] In the field of metal alloy smelting, high-silicon manganese-silicon alloy is an important alloy material.

[0003] In the related art, after the raw materials are melted into a liquid, a reducing atmosphere is vertically sprayed onto the surface of the molten liquid to carry out an oxidation-reduction reaction on the molten liquid.

[0026] Furnace body 1, induction coil 2, top cover 3, nozzle 4. Specific embodiments

[0027] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following will clearly and completely describe the technical solutions of the present invention in conjunction with the drawings. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention.

[0028] In the related art, an induction furnace is used to melt raw materials. When the induction coil 2 is energized, it will heat the raw materials in the furnace body 1 to melt them into a molten liquid. Since the molten liquid is metal, under the action of the induction coil 2, the molten liquid will form eddy currents; after the raw materials are completely melted, the control module controls the nozzle 4 to start working to spray a reducing atmosphere onto the surface of the molten liquid, causing an oxidation-reduction reaction to occur in the molten liquid.

[0029] However, in the related art, the reducing atmosphere is usually sprayed vertically downward onto the surface of the molten liquid. This spraying method can make the gas jet impact the surface of the molten pool with the maximum kinetic energy in the early stage of metal melting, forming a deeper penetration depth. Accelerate the reaction between metal oxides and reducing agents (such as CO, H 2The contact of ( ) can improve the reduction reaction rate. However, as the melting process progresses, the viscosity of the molten metal decreases in the later stage, and the flow rate increases. If the vertical injection method is still used, vortices will be generated in the high-speed melt, thereby destroying the stability of the gas-liquid interface, and the reducing gas will quickly escape from the melt surface, resulting in a decrease in the reduction efficiency.

[0030] It should be noted that similar reference numerals and letters represent similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings. In addition, in the drawings, for the effective description of the technical content, the thickness of the components can be exaggerated or reduced.

[0031] The following will describe in detail some embodiments of the present invention with reference to the drawings. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0032] As Figure 1 shown, at least one embodiment provides a reduction atmosphere detection and adjustment system for manganese-silicon alloy with high manganese content, including: a furnace body 1 for receiving manganese raw materials and silicon raw materials; an induction coil 2 surrounding the outer periphery of the furnace body 1; a top cover 3 covering the furnace body 1; a nozzle 4 located inside the top cover 3; a control module configured to control the induction coil 2 to work so that the raw materials in the furnace body 1 are melted into a liquid and form a vortex, and the control module is further configured to control the nozzle 4 to inject a reduction atmosphere into the molten liquid in the furnace body 1 after the raw materials are melted into a liquid; wherein the control module is configured to adjust the injection angle of the nozzle 4 according to the flow rate of the molten liquid to reduce the turbulence intensity of the reduction atmosphere on the molten liquid.

[0033] In this embodiment, by providing a nozzle 4 with an adjustable injection angle, the nozzle 4 adjusts to different injection angles according to the flow rate of the molten liquid, thereby reducing the turbulence intensity caused by the injected reduction atmosphere on the molten liquid.

[0034] In this embodiment, the nozzle includes but is not limited to being arranged circumferentially around the top cover of the furnace body. When the reduction atmosphere is introduced through the nozzle, the sealing performance of the furnace body is reduced to avoid excessive increase in the furnace pressure.

[0035] In some embodiments, the flow rate formula of the molten liquid is set as: ; where V is the flow rate of the molten liquid, with the unit of m / s; k is the correction coefficient; P is the output power of the induction coil, with the unit of W; μ is the viscosity data of the molten liquid, with the unit of Pa·s; R is the distance between the nozzle center and the furnace body center, with the unit of m.

[0036] In some embodiments, the formula for setting the injection angle of nozzle 4 is: ; where v n is the flow rate of the reducing atmosphere when it contacts the surface of the molten liquid, with the unit of m / s; iterative processing is performed on the injection angle of nozzle 4, and when | θ n -θ n-1 | < ε the iteration stops; where θ n is the angle corresponding to the n -th iteration of nozzle 4; θ n-1 is the angle corresponding to the nozzle after the n-1 -th iteration; ε is the preset data for determining the stop of iteration; the formula for setting the flow rate of the reducing atmosphere when it contacts the surface of the molten liquid is: v n= v 0 · e -αHn ; where v 0 is the initial flow rate of the reducing atmosphere, with the unit of m / s; α is the attenuation coefficient of the air flow, with the unit of m -1 ; H n is the height between nozzle 4 and the surface of the molten liquid, with the unit of m; e is the natural constant; the formula for setting the height between nozzle 4 and the surface of the molten liquid is: H n= H 0 ·sec(θ n-1 ） ; where H 0 is the height between nozzle 4 and the surface of the molten liquid when the angle of nozzle 4 is zero, with the unit of m.

[0037] As Figure 2 shown, at least one embodiment also provides an adjustment method for a reducing atmosphere detection and adjustment system for manganese-silicon alloy with high manganese content, including: detecting the temperature data of the molten liquid through a temperature sensor, and adjusting the injection angle of the reducing atmosphere according to the detected temperature data.

[0038] In some embodiments, the method of detecting the temperature data of the molten liquid by a temperature sensor and adjusting the injection angle of the reducing atmosphere according to the detected temperature data includes: mixing the manganese raw material and the silicon raw material and loading them into the furnace body 1; melting the raw materials in the furnace body 1 into a liquid by the induction coil 2 and forming a vortex flow; injecting the reducing atmosphere into the molten liquid through the nozzle 4; adjusting the injection angle of the nozzle 4 according to the flow rate of the molten liquid to reduce the turbulence of the injection gas flow to the molten liquid.

[0039] In this embodiment, by setting the nozzle 4 with an adjustable injection angle, the nozzle 4 is adjusted to different injection angles according to the flow rate of the molten liquid, thereby reducing the turbulence caused by the injected reducing atmosphere to the surface of the molten liquid.

[0040] In some embodiments, the method of adjusting the injection angle of the nozzle 4 according to the flow rate of the molten liquid to reduce the turbulence of the injection gas flow to the molten liquid includes: collecting the temperature data of the molten liquid to obtain the viscosity data of the molten liquid; obtaining the flow rate data of the molten liquid according to the viscosity data; adjusting the injection angle data of the nozzle 4 according to the flow rate data of the molten liquid.

[0041] In this embodiment, the output power of the induction coil P is preset during use; when the raw materials are melted into a liquid, the temperature data of the molten liquid is collected by a temperature sensor and sent to the control module. The control module is electrically connected to a memory, and a correspondence table between temperature and viscosity is preset in the memory. The control module obtains the viscosity data of the molten liquid (manganese-silicon alloy with high manganese content) at the corresponding temperature according to the received temperature data; as shown in Table 1 below (partial temperatures):

[0042] Table 1

[0043]

[0044] In some embodiments, the method of obtaining the flow rate data of the molten liquid according to the viscosity data includes: setting the flow rate formula of the molten liquid as: ; where V is the flow rate of the molten liquid, with the unit of m / s; k is the correction coefficient; P is the output power of the induction coil, with the unit of W; μ is the viscosity data of the molten liquid, with the unit of Pa·s; R is the distance between the nozzle center and the furnace body center, with the unit of m.

[0045] In this embodiment, after the raw material melts into a liquid, an eddy current will be formed under the action of the magnetic field of the induction coil. The point where the reducing atmosphere ejected by the nozzle 4 contacts the molten liquid is the point closest to the inner wall of the furnace body, and the distance between this point and the center of the eddy current is the distance between the nozzle center and the furnace body center; this formula includes variables μ , and combines variables P , so that this formula can adapt to different output powers in actual production, and the data is more comprehensive and accurate.

[0046] As Figure 3 shown, in an alternative embodiment, four nozzles 4 are provided on the top cover 3, and the nozzles 4 are evenly arranged along the circumference of the top cover. The upper end of the nozzle 4 is hinged to the top cover 3, and the rotation direction of the nozzle 4 is: the tangential direction of the circle where each nozzle 4 is located, and towards the flow direction of the molten liquid; among them, a servo motor electrically connected to the control module is used to drive the nozzle 4 to rotate.

[0047] In an alternative embodiment, the correction coefficient k is 0.0001058, k obtained by multiple measurement fittings; the output power P of the induction coil is 150,000 W; the viscosity data μ of the molten liquid (manganese-silicon alloy with high manganese content) at 1450 °C is 0.07 Pa·s; the distance between the nozzle center and the furnace body center R is 0.6 m.

[0048] Substitute the above parameters into the flow velocity formula of the molten liquid , V is about 0.2 m / s.

[0049] In some embodiments, the flow velocity formula when the reducing atmosphere contacts the surface of the molten liquid is set as: v n= v 0 · e -αHn ; where v n is the flow velocity of the reducing atmosphere when it contacts the surface of the molten liquid, with the unit of m / s; v 0 is the initial flow velocity of the reducing atmosphere, with the unit of m / s; α is the attenuation coefficient of the gas flow, with the unit of m -1 ; H n is the height between the nozzle 4 and the surface of the molten liquid, with the unit of m; e is the natural constant.

[0050] In this embodiment, the initial flow velocity of the reducing atmospherev 0 is preset. When the reducing atmosphere is sprayed onto the surface of the molten liquid, the speed will be lower than v 0 and changes according to the length of the spraying path. Therefore, by collecting the initial flow rate v 0 of the reducing atmosphere and obtaining the distance between the nozzle 4 and the surface of the molten liquid, the speed of the reducing atmosphere when it contacts the surface of the molten liquid can be calculated v n .

[0051] In some embodiments, the height formula between the nozzle 4 and the surface of the molten liquid is set as: H n= H 0 · sec (θ n-1 ） ; where H 0 is the height between the nozzle 4 and the surface of the molten liquid when the angle of the nozzle 4 is 0 degrees, with the unit of m, and this height H 0 is data that can be obtained in advance.

[0052] In this embodiment, when the angle of the nozzle 4 does not change (i.e., the angle of the nozzle 4 is 0 degrees), the nozzle 4 sprays the reducing atmosphere vertically onto the surface of the molten liquid. At this time, the height between the nozzle 4 and the surface of the molten liquid is H 0 ; when the spraying angle of the nozzle 4 is changed, the height H n between the nozzle 4 and the surface of the molten liquid will also change, thereby changing the spraying path of the reducing atmosphere.

[0053] In some embodiments, the method for adjusting the spraying angle data of the nozzle 4 according to the flow rate data of the molten liquid includes: setting the spraying angle formula of the nozzle 4 as: ; where v n is the flow rate of the reducing atmosphere when it contacts the surface of the molten liquid, with the unit of m / s.

[0054] In some embodiments, the method for adjusting the spraying angle data of the nozzle 4 according to the flow rate data of the molten liquid further includes: performing iterative processing on the spraying angle of the nozzle 4, and stopping the iteration when | θ n - θ n-1 | < ε ; where θ n is then The angle corresponding to nozzle 4 after the θ n-1 For the n-1 angle corresponding to nozzle 4 after the ε is the preset data for judging the stop of iteration.

[0055] In an optional embodiment, θ 0 is the angle data when not adjusted, that is θ 0 is 0 degrees; H 0 is the height data between nozzle 4 and the molten liquid surface when nozzle 4 is vertically downward without adjustment, that is H 0 is 1 m; adopting the flow rate of the molten liquid in the above embodiment, V is 0.2 m / s; the initial flow rate of the reducing atmosphere v 0 is 0.5 m / s; the attenuation coefficient of the air flow α is 0.2 m -1 ; ε is 0.10°; e is the natural constant.

[0056] The first iteration process is:

[0057] The height between nozzle 4 and the molten liquid H 1 =H 0 ·sec(θ 0 ） , that is H 1 = 1 m.

[0058] The gas flow rate of the reducing atmosphere when contacting the molten liquid surface , that is v 1 = 0.4094 m / s.

[0059] The 1 spray angle after the , that is θ 1 = 26.01° (the result is rounded to two decimal places).

[0060] Judge: | θ 1 - θ 0 | = 26.01° > ε , continue to iterate.

[0061] The second iteration process is as follows:

[0062] The height between the nozzle 4 and the molten liquid H 2 =H 0 ·sec(θ 1 ) , that is H 2 = 1.103 m.

[0063] The gas flow rate of the reducing atmosphere when contacting the surface of the molten liquid , that is v 2 = 0.4012 m / s.

[0064] The 2 spray angle after the th iteration θ 2= 26.57°.

[0065] Judgment: | θ 2 - θ 1 | = 0.56° > ε , continue the iteration.

[0066] The third iteration process is as follows:

[0067] The height between the nozzle 4 and the molten liquid H 3 =H 0 ·sec(θ 2 ) , that is H 3 = 1.096 m.

[0068] The gas flow rate of the reducing atmosphere when contacting the surface of the molten liquid , that is v 3 = 0.4014 m / s.

[0069] The 3 spray angle after the th iteration θ 3 = 26.57°.

[0070] Judgment: | θ 3 - θ 2 | = 0° < ε , stop the iteration, and the nozzle 4 adopts θ3 Jet at an angle.

[0071] In summary, the reduction atmosphere detection and adjustment system and adjustment method for the high-manganese-content ferromanganese-silicon alloy avoid the vortex generated by the melt flow caused by a fixed injection angle, which destroys the stability of the gas-liquid interface and causes the reduction gas (such as H 2 , CO) to quickly escape from the melt surface, reducing the effective reaction time and causing a problem of product quality decline by setting the nozzle 4 with an adjustable injection angle, so that the nozzle 4 adjusts to different injection angles according to the different flow rates of the molten liquid.
