Description

Technical Field

[0001] The invention belongs to the field of detection technology, and in particular relates to a reducing atmosphere detection and adjustment system and an adjustment method for a manganese-silicon alloy with a high manganese content. Background Art

Obviously, the drawings described below are some implementation methods of the present invention.

[0024] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] In the related art, an induction furnace is used to melt the raw materials. When the induction coil 2 is energized, the raw materials in the furnace body 1 are heated to melt the raw materials into molten liquid. Since the molten liquid is metal, the molten liquid will form an eddy current under the action of the induction coil 2. When 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 the molten liquid to undergo an oxidation-reduction reaction.

[0026] However, in related technologies, reducing atmosphere is usually sprayed vertically downward onto the surface of the molten liquid. This spraying method allows the gas jet to impact the surface of the molten pool with maximum kinetic energy in the early stage of metal melting, forming a deeper penetration depth. It accelerates the contact between metal oxides and reducing agents (such as CO, H2) and increases the reduction reaction rate. However, as the melting state proceeds, the viscosity of the metal melt decreases and the flow rate increases. If the vertical spraying method is still used, the high-speed melt will generate vortices, thereby destroying the stability of the gas-liquid interface, and the reducing gas quickly escapes from the surface of the melt, resulting in a decrease in reduction efficiency.

[0030] In this embodiment, the nozzle 4 with adjustable spray angle is provided so that the nozzle 4 can be adjusted to different spray angles according to the flow rate of the molten liquid, thereby reducing the turbulence intensity caused by the sprayed reducing atmosphere on the molten liquid.

[0031] In this embodiment, the nozzles include but are not limited to being arranged circumferentially around the top cover of the furnace body, and when the nozzles are used to introduce reducing atmosphere, the sealing of the furnace body is reduced to avoid excessive increase in pressure in the furnace.

[0032] In some embodiments, the flow rate of the molten liquid is set as follows: ;in, V is the flow rate of the molten liquid, in m / s; k is the correction coefficient; P is the output power of the induction coil, in W; m is the viscosity data of the molten liquid, in Pa·s; R It is the distance between the nozzle center and the furnace center, in meters.

[0034] like Figure 2 As shown, at least one embodiment also provides a method for adjusting a reducing atmosphere detection and adjustment system for a high manganese content manganese silicon alloy, comprising: detecting temperature data of a molten liquid by a temperature sensor, and adjusting the injection angle of the reducing atmosphere according to the detected temperature data.

[0036] In this embodiment, by providing a nozzle 4 with an adjustable spray angle, the nozzle 4 is adjusted to different spray angles according to the flow rate of the molten liquid, thereby reducing the disturbance of the sprayed reducing atmosphere on the surface of the molten liquid.

[0037] In some embodiments, a method for adjusting the spray angle of the nozzle 4 according to the flow rate of the molten liquid to reduce the disturbance of the jet airflow to the molten liquid includes: collecting temperature data of the molten liquid to obtain viscosity data of the molten liquid; obtaining flow rate data of the molten liquid according to the viscosity data; and adjusting the spray angle data of the nozzle 4 according to the flow rate data of the molten liquid.

[0038] In this embodiment, the output power of the induction coil is PIt is pre-set when in use; when the raw material is melted into liquid, the temperature data of the molten liquid is collected by the temperature sensor and sent to the control module. The control module is electrically connected to a memory. The memory is pre-set with a corresponding table between temperature and viscosity. 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 temperature): Table 1

[0039] 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 to: ;in, V is the flow rate of the molten liquid, in m / s; k is the correction coefficient; P is the output power of the induction coil, in W; m is the viscosity data of the molten liquid, in Pa·s; R It is the distance between the nozzle center and the furnace center, in meters.

[0040] In this embodiment, when the raw material is melted into liquid, the molten liquid will form an eddy current under the action of the magnetic field of the induction coil.

[0042] In an optional embodiment, the correction factor k is 0.0001058, k Obtained through multiple measurements and fitting; the output power of the induction coil P 150000W; viscosity data of molten liquid (high manganese content manganese silicon alloy) at 1450°C m 0.07Pa·s; the distance between the nozzle center and the furnace center R It is 0.6m.

[0043] Substituting the above parameters into the flow rate formula of the molten liquid middle, V About 0.2m / s.

[0044] In some embodiments, the flow rate of the reducing atmosphere when contacting the molten liquid surface is set as follows: v n= v 0 · e -αHn ;in, v n is the flow rate of the reducing atmosphere when it contacts the surface of the molten liquid, in m / s; v 0 is the initial flow rate of the reducing atmosphere, in m / s; α is the attenuation coefficient of the airflow, in m -1 ; H n is the height between the nozzle 4 and the surface of the molten liquid, in m; e is a natural constant.

[0045] In this embodiment, the initial flow rate of the reducing atmosphere is v 0 It is pre-set that when the reducing atmosphere is sprayed onto the surface of the molten liquid, the speed will be faster than v 0 The initial flow rate of the reducing atmosphere is small and varies according to the length of the injection path; therefore, v 0 , obtain the distance between the nozzle 4 and the surface of the molten liquid, and then calculate the speed of the reducing atmosphere when it contacts the surface of the molten liquid v n .

[0046] In some embodiments, the height between the nozzle 4 and the surface of the molten liquid is set as follows: H n= H 0 · seconds (i) n-1 ） ;in, H 0 It is the height between the nozzle 4 and the molten liquid surface when the angle is 0 degrees, in meters. H 0 This is data that can be obtained in advance.

[0047] In this embodiment, when the angle of the nozzle 4 does not change (that is, 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 spray angle of the nozzle 4 is changed, the height between the nozzle 4 and the surface of the molten liquid H n will also change, thereby changing the reducing atmosphere injection path.

[0048] In some embodiments, the method for adjusting the spray angle data of the nozzle 4 according to the flow rate data of the molten liquid includes: setting the spray angle formula of the nozzle 4 as: ;in, v n It is the flow rate of the reducing atmosphere when it contacts the surface of the molten liquid, measured in m / s.

[0051] The first iteration process is: The height between the nozzle 4 and the molten liquid H 1 =H 0 ·sec(θ 0 ） ,Right now H 1 =1m.

[0052] The gas flow rate of the reducing atmosphere when it contacts the molten liquid surface ,Right now v 1 =0.4094m / s.

[0054] Judgment: | i 1 - i 0 |=26.01°> e , continue iterating.

[0055] The second iteration process is: The height between the nozzle 4 and the molten liquid H 2 =H 0 ·sec(θ 1 ) ,Right now H 2 =1.103m.

[0056] The gas flow rate of the reducing atmosphere when it contacts the molten liquid surface ,Right now v 2 =0.4012m / s.

[0057] No. 2 The injection angle after iteration ,Right now i 2= 26.57°.

[0058] Judgment: | i 2 - i 1 |=0.56°> e , continue iterating.

[0059] The third iteration process is: The height between the nozzle 4 and the molten liquidH 3 =H 0 ·sec(θ 2 ) ,Right now H 3 =1.096m.

[0060] The gas flow rate of the reducing atmosphere when it contacts the molten liquid surface ,Right now v 3 =0.4014m / s.

[0061] No. 3 The injection angle after iteration ,Right now i 3 =26.57°.

[0062] Judgment: | i 3 - i 2 |=0°< e , stop iteration, nozzle 4 uses i 3 Angle spray.

[0063] In summary, the reducing atmosphere detection and adjustment system and adjustment method for high manganese content manganese silicon alloy is provided with a nozzle 4 with an adjustable injection angle, so that the nozzle 4 is adjusted to different injection angles according to the different flow rates of the molten liquid, thereby avoiding the problem that the melt flow caused by the fixed injection angle generates a vortex, destroys the stability of the gas-liquid interface, causes the reducing gas (such as H2, CO) to quickly escape from the melt surface, and reduces the effective reaction time, resulting in a decrease in product quality.
