Supply light weight brick for kiln inner lining in low price
Introduction
The light weight brick are used as the main raw material alumina hollow ball, high performance Micropowder for additives, organic material temporary binder high temperature shuttle kiln baked.
Characteristized:
1. containing a large number of closed pores
2. have a lightweight high temperature
3. good insulation properties
4. refiring small contraction
5. excellent thermal shock resistance
7. strong resistance to the corrosive gas and slag.
light weight brick can greatly improve the thermal efficiency of the kiln to shorten the production cycle, reduce the kiln body weight to achieve energy saving.
Application:
The light weight brick can be in direct contact with the flame, to apply to the cracking furnace, hot stove, furnace, tunnel kiln, push board kiln, crucible furnace and electric furnace, electric kilns lined widely used in metallurgy, refractories, light industry, chemical industry, ceramics, glass, electronics and other industries. Dimensions of the product, the physical and chemical indicators, service life have reached or exceeded the level of similar products at home and abroad
