Product introduction
1、 Main characteristics:
1. Strong thermal shock resistance, stable chemical property, SiO2 content greater than 99%, anti invasion
Excellent corrosion and acid resistance.
2. The content of low Fe 2O3 is less than 0.1%, and the products (such as liquid glass) are free of pollution
Dye.
3. Low flux index (Al2O3+2R2O) less than 0.3%, corrosion resistance, high resistance
Good temperature property.
4. The thermal expansion rate is close to zero, so it is unnecessary to reserve expansion joints during repair to increase the tightness of masonry.
5. It is not easy to stick carbon under high temperature and long time use, and has good corrosion resistance to molten steel.
6. Excellent thermal stability, products will not crack during hot repair, and can be repaired directly under high temperature without stopping the furnace
Industry.
7. After repair (hot repair), there will be no peeling and other phenomena, and it is safe and reliable for long-term use.
8. It is not necessary to dry the furnace for a long time after masonry; No preheating is required.
2、 Main purpose:
It is widely used in metallurgy, chemical industry and light industry. It is mainly used as submerged nozzle in continuous casting in metallurgical industry; Carbon in coke oven
Chemical chamber and other parts. In the chemical industry, it is mainly used as the roof of glass furnace. The zero expansion silica brick has small expansion rate and thermal stability
High compressive strength and other characteristics, so it is easy to make large blocks, and the surface is smooth without carbon deposition. Coke oven doors and
The gas riser is widely used, and its service life is nearly 15 times longer than that of clay brick.
