The company produces refractories are: silica brick, clay brick, unshaped refractories, quality and reputation in the industry to get a good evaluation.
First, the most basic is the acidic nature of silica brick belongs.
The true density of silica brick smaller, more complete conversion of the lime, resulting in a residual expansion process also smaller oven. In silica brick, the true density of quartz smallest scales, small linear expansion coefficient, thermal stability better than cristobalite and quartz, good thermal conductivity, high load softening temperature, slag corrosion resistance, is the volume of quartz most stable form . The calcination is preferably silica brick, the highest content of tridymite, 50% to 80%; followed cristobalite, only 10% ~ 30%; quartz glass and the content of the fluctuation in the phase of 5% to 15%.
When the temperature is below 600 ~ 700 ℃, the larger the volume of silica brick changes, poor resistance to thermal shock properties, thermal stability is not good. If long-term coke at such a temperature, it is easily broken broken masonry.
