Selection Principle and General Method of Refractory for Furnace

The main performance of the furnace is mainly determined by the technical and economic performance of the refractory insulation material, which directly affects the investment cost, working performance, thermal efficiency and running energy consumption of the kiln. Select the general principles of fire-resistant insulation materials:
1, the performance of the kiln and thermal characteristics, such as the gap between the work of the kiln should use low heat capacity of the material;
2, the safe use of materials temperature, thermal conductivity system, high temperature strength, chemical stability;
3, the use of life;
4, investment costs and operating maintenance costs.

In general, heavy refractory material is more focused on a technical performance indicators, such as high temperature stability, chemical stability; light weight insulation materials pay more attention to investment and operation of the integrated technical and economic indicators.

When using lightweight insulation materials, the general thermal insulation material thermal conductivity (λ) and the cost per unit volume of insulation material (P) to determine, "λP" product value as small as possible. Thermal conductivity value is small, indicating the insulation effect of insulation materials, running the energy costs low. Low cost per unit volume of insulation material that investment costs are low, with good investment in economic results. Can be plotted with coordinate mapping choice, the abscissa for the operating temperature, the vertical coordinate (λP) good product, with the safe use of materials, intercept the temperature curve of the material, Select the technical and economic performance of the material.
