The main performance of industrial kiln is mainly determined by the technical and economic performance of refractory materials, which directly affects the investment cost, working performance, thermal efficiency and energy consumption cost of operation of kiln. The general principle of selecting insulation brick and other refractory insulation materials:
1.Performance and thermal characteristics of kiln. Such as gap work kiln should choose low heat capacity materials.
2.Safe use temperature, heat conduction system, high temperature strength and chemical stability of materials.
3.Service life.
4.Investment cost and operation maintenance cost.
Generally speaking, heavy refractories focus on a certain technical performance index, such as high temperature stability, chemical stability, etc. Light resistant thermal insulation materials pay more attention to the comprehensive technical and economic indicators of input and operation.
The thermal conductivity (λ) of the insulation material and the cost per unit of (lambda) of the Inner Mongolia (Inner Mongolia) of the Inner Mongolia (Inner Mongolia) are generally determined, the smaller the product of "lambda (Inner Mongolia)", the better.
A small value of thermal conductivity indicates that the thermal insulation material has good thermal insulation effect and low energy cost during operation. The low cost per unit volume of thermal insulation material indicates that the investment cost is low and has a good economic effect of investment. The curves of (λ Rho) (Inner Mongolia) of the materials can be captured using the safe service temperature of the materials.
