Refractory Zero Expansion Silica Brick With Super Thermal Stability
Features
1. Excellent thermal shock resistance
2. Product has no size change, crack and deformation after more than 30 cycle times in1100°Cwater-cooling test, and can has repair operation directly without furnace shutdown under high temperature.
3. Direct operation without preheating
4. Good and stable chemical properties under high temperature
5. No impurity pollution, corrosion and peeling after repairing the coke furnace. Safe&Reliable after long-term use
6. Small bulk&density. Compared with other hot repairing materials, actual procurement cost is reduced.
Applications
Light weight silica brick is mainly used to preserve heat in glass industry, iron&steel industry and ceramic furnace.
