General Information of SilicaBrick For Coke Oven

Our corporation produces a comprehensive range of silicabricks, with high silica content, all of these bricks exhibit excellentperformance.

Our Silica bricks are the final result of blendingexcellent tridymite and cristobalite, as the main raw materials withcutting-edge technology, after mixing, drying, forming, in the high temperatureshuttle kiln. There are also little quartz and vitreous within. We ensure youthat the silica bricks made by us possess high quality standard and have gonethrough all the complicated quality control parameters. Their durability andstrength adds life to the structure and they have the capacity of bearing hightemperature.

Feature of Silica Brick For Coke Oven

Resistant to thermal shock, abrasion, chemical attack

High ability for anti-abrasion during work

Q:The high thermal conductivity of silica brick and traditional brick what is the difference?
The scale quartz is a spear shaped double crystal structure, very compact and favorable to the increase of thermal conductivity. The high thermal conductivity of silica brick in improving thermal conductivity and other performance indicators and traditional coke silicabrick agreement.That is to say, the high thermal conductivity of silica brick all inherited the traditional advantages of coke oven silica brick, on the basis of further highlight the characteristics of high thermal conductivity
Q:The brick is mainly used in the place?
Also used for high temperature bearing part of hot blast stove and acid open hearth furnace.
Q:Common bond brick?
Manufacturing for silica brick binder hi-li sulfate pulp waste liquid and lime milk. When lime milk is used as a bond, it acts as a plasticizer. To increase the strength of lime brick in the drying process, as mineralizer in the firing, promote the transformation of quartz.
Q:The specific content is what gb/t2608-2012 brick
The provisions of the brick classification, technical requirements, test methods,
Q:The introduction of silica brick
Acidic silica brick refractory material, has good acid resistance and slag erosion, softening temperature is as high as 1640 to 1670 DEG C, in the long-term use volume is relatively stable under high temperature.
Q:How much is the highest melting point of silicon?
Acidic silica brick refractories, softening temperature is as high as 1640 to 1670 DEG C, in the long-term use volume is relatively stable under high temperature. More than 94% silica content.
Q:Why will expand when heated brick
Because the production of raw materials are silica brick, brick with SiO2 content of not less than 95% of silica as raw materials, adding mineralizer and binder, through mixing, molding, drying, sintering and other processes in the system
Q:High temperature refractory material?
Special materials often use AZS brick (i.e. corundum brick), corundum brick, magnesia chrome bricks, silicon carbide, silicon nitride bonded silicon carbide, nitrides, silicides, sulfide, boride, carbide and other non oxide refractory materials; calcium oxide, chromium oxide, alumina, Magnesium Oxide, beryllium and other refractory materials. Insulation refractories are often used diatomite products, asbestos products, insulation board. Unshaped refractories are often used refractory castable, refractory clay, refractory ramming material, refractory plastic and fettling material, fire resistance, gunning, refractory cast material, fireproof coating, lightweight refractory castable, gun mud.
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 introduction of silica brick?
The characteristics of silica brick:Brick belongs to refractory materials, with strong resistance to acid slag or acid solution erosion ability, high load softening temperature are excellent properties of silica brick, usually 1640-1680 C.The use of silica brick:Mainly used for masonry brick oven carbonization chamber, a combustion chamber and a partition wall, glass furnace and kiln roof, pool wall, high temperature hot blast furnace, glass furnace, load-bearing pool wall, hot blast stove, baking furnace of carbon bearing part of high temperature furnaces etc..
