Description

Technical Field

[0001] The present invention relates to the field of mineral wool, and more specifically, to a method, device, equipment, medium and product for calculating the cooling water volume of a condensing furnace lining of a 4700mm diameter mineral wool electric furnace. Background Art

[0002] With the deepening of dual carbon emission reduction, energy conservation and carbon reduction in the rock wool industry are becoming increasingly important. Traditional rock wool production uses the cupola process to melt raw materials. The melting energy is coke, which not only consumes a lot of energy, but also emits a lot of CO2 during the production process. In recent years, various countries have been promoting the adjustment of rock wool melting technology, changing the cupola to a greener and lower-carbon electric melting furnace process.

[0003] At present, there are two main types of rock wool electric furnace processes: one is the cold material rock wool electric furnace, and the other is the hot slag rock wool electric furnace. The two processes use different solutions for the refractory materials of the electric furnace wall. The refractory materials of the cold material rock wool electric furnace are thin-walled slag-hanging type, that is, during the production and operation process, the thin-walled refractory materials with good thermal conductivity form a slag layer under strong cooling conditions, which can well protect the furnace wall refractory materials and extend the service life of the electric furnace. According to actual production data, a 20-30mm thick slag layer can be formed in the cold material electric furnace during the production and operation process, and the service life of the refractory materials is usually more than 1 year, and can generally reach 2 years. The hot slag rock wool electric furnace usually uses a thick-walled insulation furnace wall, and the furnace wall cannot form a slag layer for protection. The service life of the refractory materials is generally only half a year, and some are even only 3-4 months.

[0004] The protection of the condensing lining of the rock wool electric furnace is a necessary means to increase the service life of the refractory. However, in order to ensure that the condensing lining can form a sufficient thickness of slag protection, there is still a lack of methods to accurately adjust the cooling water volume of the furnace wall of the rock wool electric furnace. Therefore, it is urgent to develop a method to calculate the cooling water volume of the condensing lining of the rock wool electric furnace. Summary of the invention

[0005] In view of the defects existing in the prior art, the purpose of the present invention is to provide a method, device, equipment, medium and product for calculating the cooling water volume of the condensing furnace lining of a 4700mm diameter mineral wool electric furnace. By means of numerical simulation, the cooling intensity of the condensing furnace lining on the 4700mm diameter mineral wool electric furnace to form a suitable slag skin protection and the functional relationship between the cooling water volume and the slag skin thickness are calculated, and the cooling water volume data required for the condensing furnace lining when different target slag skin thicknesses are obtained are accurately calculated.

[0039] In order to better understand the above technical solution of the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0040] Combination Figure 1 As shown, the present invention provides a method for calculating the cooling water volume of the condensing furnace lining of a 4700mm diameter mineral wool electric furnace;

[0041] Obtain the physical properties of the melt and refractory materials of a 4700mm diameter mineral wool electric furnace, including density, specific heat, viscosity, thermal conductivity, electrical conductivity, and solid-liquid phase temperature. The melt density is 2.5-2.7 g·cm -3 Specific heat is 1200~1495j·kg -1 ·K -1 ; Viscosity is 0.25~0.8Pa·s; Thermal conductivity is 0.3~0.5W·m -1 ·K -1 ; Conductivity is 1.5~20S·m -1 ; The solid-liquid phase temperature is 1453~1513K.

[0042] The furnace wall refractory material of the 4700mm diameter rock wool electric furnace is made of silicon carbon ramming material with a thickness of 30mm and a thermal conductivity of 15.51~20.28W·m -1 ·K -1 .

[0043] Based on the furnace parameters of 4700mm diameter rock wool electric furnace, a three-dimensional physical model of the electric furnace is established and the grid is divided, including structural parameters such as furnace height, diameter, electrode diameter, polar center circle diameter, and slag inlet and outlet positions. The computational domain grid is divided by combining structured and unstructured grids, and the total grid volume is about 200w.

[0044] Solve Maxwell's equations to obtain electromagnetic field related parameters, calculate electromagnetic field equations, and establish a multi-field coupling mathematical model. By solving Maxwell's equations to obtain the distribution of electromagnetic field related parameters, the time-averaged Joule heat and electromagnetic force calculated by the harmonic method are added as source terms to the energy and momentum equations respectively to achieve coupling between the electromagnetic field and the flow field and temperature field.

[0045] The multi-field coupling mathematical model is used to calculate the cooling water volume data of the condensing lining of a 4700mm diameter rock wool electric furnace.

[0046] The functional relationship between the cooling water volume of the condensing furnace lining and the slag thickness of the 4700mm diameter rock wool electric furnace is established, such as Figure 2 As shown in the figure, there is a quadratic function relationship between the cooling water volume V of the condensing furnace lining of a 4700mm diameter rock wool electric furnace and the slag skin thickness H:

[0047] V=0.0165*H 2 -1.9231*H+216.32(R 2 =0.9956)

[0048] When the condensing furnace lining forms a complete slag skin protective layer with a slag skin thickness of 118 mm, the cooling water volume is 220 m 3 / h;

[0049] When the condensing furnace lining forms a complete slag skin protective layer and the slag skin thickness is 109mm, the cooling water volume V value is 200m 3 / h;

[0050] When the condensing furnace lining forms a complete slag skin protective layer with a slag skin thickness of 92 mm, the cooling water volume V value is 180 m 3 / h;

[0051] When the condensing furnace lining forms a complete slag skin protective layer with a slag skin thickness of 58 mm, the cooling water volume V value is 160m 3 / h.

[0052] When the cooling water volume V value is 150m 3 / h, although the average thickness of the slag skin of the condensing furnace lining reaches 38mm, no slag skin is formed in some areas. Therefore, in order to obtain a complete and stable slag skin protective layer, the V value of the cooling water volume of the condensing furnace lining needs to be greater than 150m 3 / h.

[0056] The model application unit 530 uses a multi-field coupling mathematical model to calculate the cooling water volume data of the condensing furnace lining of the 4700mm diameter rock wool electric furnace, and establishes a functional relationship between the cooling water volume of the condensing furnace lining of the 4700mm diameter rock wool electric furnace and the slag skin thickness.

[0057] The model building unit 510 builds a three-dimensional physical model of the electric furnace and divides the grid based on the furnace parameters of the 4700mm diameter rock wool electric furnace, including structural parameters such as the furnace height, diameter, electrode diameter, polar center circle diameter, and slag inlet and outlet positions. The computational domain grid is divided by combining structured and unstructured grids, and the total grid volume is about 200w.

[0058] The solution strategy setting unit 520 obtains the distribution of electromagnetic field related parameters by solving the Maxwell equations, and adds the time-averaged Joule heat and electromagnetic force calculated by the harmonic method as source terms to the energy and momentum equations respectively, to achieve coupling between the electromagnetic field and the flow field and temperature field.

[0059] The model application unit 530 uses a multi-field coupling mathematical model to calculate the cooling water volume data of the condensing furnace lining of a 4700mm diameter rock wool electric furnace, and establishes a functional relationship between the cooling water volume V of the condensing furnace lining of a 4700mm diameter rock wool electric furnace and the slag skin thickness H, that is, V = 0.0165*H 2 -1.9231*H+216.32(R 2 =0.9956)
