Applications Of Kerui Refractory Fire Bricks
Sintering Furnaces and KilnsRefractory bricks are commonly used in the construction of sintering furnaces and kilns for ceramics, cement, lime, ore and other materials. They are able to withstand high temperatures for long periods of time.
Glass FurnacesIn the glass manufacturing industry, refractory bricks are used to construct glass furnaces that require high temperatures to melt the glass feedstock.
Steel SmeltingIn the steel industry, refractory bricks are used to build blast furnaces, converters, electric arc furnaces and other smelting equipment to withstand high temperatures and chemical attack.
Coal Gasifiers and Chemical IndustryRefractory bricks are also used in coal gasifiers, chemical reactors and other chemical industry applications because these furnaces need to withstand high temperatures and corrosive chemicals.
Industrial High-temperature Furnace BodyRefractory bricks are often used to manufacture industrial furnace bodies, such as high-temperature smelting furnaces, incinerators, glass furnaces, steel furnaces, etc.
Coal gasifiers and chemical industryRefractory bricks are also used in coal gasifiers, chemical reactors and other chemical industry applications because these furnaces need to withstand high temperatures and corrosive chemicals.
