silica bricks for coke oven
silica brick is made of quartz stone material, the content of SiO2 is above 93%,it has good resistance to acid slag and good heat conductivity. And the refractoriness is 1690~1710°C,RUL is beyond 1620°C.
SiO2 has different types of crystals in different temperatures, and the transform between the crystals will cause the change of the bulk. So there is a close contact between the changes of SiO2 crystals and the produce ,performance and usage of silica bricks. During the heating, there will be changes of the bulk ,and cristobalite changes most, then quartz, phosphorus quartz is the slowest of all and it also has good heat-conductivity.Coke oven should use the silica brick with small true density. And the phosphorus quartz is better than others.
Silica brick application:
Mainly used in the construction of regenerative chamber, chute, combustion chamber, coking chamber, furnace roof etc. parts of the coke ovens.
silica brick for glass kiln
Mainly used for coke oven of coking chamber and combustion chamber partition, steel open hearth of regenerative chamber and sediment chamber, soaking furnace, glass melting furnace, refractory silica brick materials and ceramic firing kiln and kiln of the vault and other supporting parts. Also used in hot blast stove of high temperature bearing parts and acid open hearth furnace roof.
- Q: Application of electric high temperature regulating valve?
- Magnesia brick has good resistance to alkaline slag and slag, refractory clay brick and brick high ratio. Mainly used in open hearth furnace, oxygen converter, electric furnace, non-ferrous metal smelting equipment and glass industry as well as some high temperature equipment. Magnesia chrome brick more resistant to alkaline slag, and thermal shock stability are much higher than the more widely used, magnesia, magnesia chrome bricks in iron and steel smelting and non-ferrous metal smelting industry has almost replaced the brick, chrome oxide containing (Cr2O3) can be spread, the magnesium chromium brick can easily sticking kiln the skin, so in the past 30 years, has been used with refractory preferred cement kiln, magnesia chrome brick in Cr2O3 water after the reaction of trivalent chromium into six chromium can cause the pollution on the water, facing gradually out of the cement industry market trends. Magnesia and magnesia alumina brick using alumina as raw materials, a magnesia brick compared to thermal shock resistance and high temperature creep performance, use parts and magnesia brick is almost the same. Dolomite brick and magnesia calcium brick performance is almost the same, dolomite brick using dolomite as raw material, calcium magnesium brick with synthetic calcium magnesium sand as raw materials, calcium oxide content in 15-30%, the other is the main component of Magnesium Oxide, with the function of purifying molten steel, usually only used for special steel smelting, the production process of magnesia calcium brick complex water and water steam, easy decomposition, not easy to save transportation, do preventive work must be used in the process of. Magnesia spinel brick is a kind of new products, mainly for the zone and transition zone of cement rotary kiln, will be the main products of the cement industry to replace magnesia chrome brick.
