General Information
No thermal expansion silica bricks also known as fused silica brick ,fused silica brick or silica bricks. It has a very low thermal expansion coefficient. Excellent thermal shock resistance. Good structural strength at high temperatures. High content of SiO2 etc. The product can be widely used in various types of coke oven heat fast restoration. Coke oven maintenance time shortens greatly. Ensure the quality of coke oven repair. Improve the efficiency of coke oven production. We not only provide hot repair methods on coke oven and also contract hot repair project for coke oven.
Feature
No thermal expansion silica bricks has better thermal shock resistance, much lower thermal expansion, and can be used to do hot repair.
Fused Silica Brick for Hot Repair of Coke Oven is similar to general silica brick, but it has better thermal shock resistance.
Our fused silica bricks can remain the original shape of design as well as increasing the glass furnace service life.
The founder of our company is an expert in zero expansion silica brick(also called fused silica brick), fused silica bricks are tested to perform excellently in service of glass furnace.
Photos for Workshop
- Q: The introduction of silica brick
- The silica mineral phase is mainly composed of tridymite and cristobalite, there is a small amount of quartz and glass
- Q: Why will expand when heated brick
- After high temperature after the formation of tridymite and cristobalite and quartz and a small amount of residual glass phase, quartz heating to 220-240 DEG C, in a certain degree of thermal expansion, brick maximum expansion occurs in 100~300 DEG C, 300 expansion before the total amount of expansion is about 70%~75%.
- Q: Semisilica brick interpretation
- High temperature volume stability. Volume change is small.
- Q: Semisilica brick, clay brick, high alumina brick and what is the difference?
- This is a kind of refractory material is divided into three types: semisilica brick (A12O315 ~ 30%), clay brick (A12O330 ~ 48%), high aluminum brick (A12O3>48%).
- Q: The United States of our brick anti-dumping duties?
- At present of our brick anti-dumping rate is 73.10%
- Q: Can iron oxide be used as refractory material?
- Iron oxide can not be used as refractory material, but it can be used as refractory additive. Iron oxide can be used as pigment
- Q: The high thermal conductivity of silica brick and traditional brick what is the difference?
- Brick, high thermal conductivity has been greatly improved in terms of morphology, crystal structure, physicochemical index. The structure and morphology of high thermal conductivity of silica brick,Structure and morphology of high thermal conductivity and the traditional brick brick magnified 20 times were compared, high thermal conductivity silica pore size distribution is more uniform and finer.
- Q: What are the main constituents of refractory bricks?
- Clay brick and clay brick are mainly composed of mullite (25% ~ 50%), glass phase (25% ~ 60%) and square quartz and quartz (up to 30%). Usually with hard clay as raw material, pre calcined mature material, and then with soft clay, semi dry or plastic molding, the temperature at 1300~1400 C fired clay brick products. Can also be added a small amount of water, glass, cement and other binders to make non burning products and amorphous materials. It is a refractory brick commonly used in blast furnaces, hot blast furnaces, heating furnaces, power boilers, lime kilns, rotary kilns, ceramics and refractory bricks.
- Q: The chemical composition of silica brick and its physicochemical index?
- The physicochemical index of silica brick:Turn left to |
- Q: Physical solid waste disposal
- Too much addition will reduce the refractory and mechanical strength, increase porosity, so the amount of waste brick should not be too much.
