Need to have enough refractoriness, good thermal shock resistance, enough mechanical strength, can bear high temperature mechanical flushing action.
2. Under operating temperature, need to have the abilities of higher chemical stability, stronger resistance to molten glass erosion and washing, and under the operating temperature, the volume is fixed, reheat shrinkage and thermal expansion rate should be very small, and the load softening temperature is high, the product has no deformation or rarely.
3. Do not pollute the glass or very little pollution, and have no bad influence to other adjacent refractory.
4. Thermal performance should meet the use requirements, the size of the shape need to be neat, accurate and cheaper price.
5. Each part of the glass kiln using refractory life should try to balance and match.
