How To Choose Refractory For Glass Furnace Use

The main performance of a glass furnace is mainly determined by the technical and economic performance of refractory materials, which directly influences the investment cost, working performance, thermal efficiency and energy consumption cost. General principles for selecting the refractory materials is as below, such as fused cast azs block, zircon brick, zircon mullite block, etc.:

 

1. The performance and thermal characteristics of glass furnace, for instance,  gap working furnace should select low heat capacity refractory material.

 

2. Safety using temperature, thermal conductivity, high temperature strength, chemical stability of refractory material.

 

3. Sevice life

 

4. Investment cost and maintenance cost

 

Generally speaking, heavy refractory materials more focus on a certain technical performance index, such as high temperature stability, chemical stability. Light insulation refractory materials pay more attention to comprehensive technical and economic indicators of investment and operation.
