Kiln refractory Clay Fire Bricks is made from clinker clay by mixing, forming, drying, sintering and machine pressing moulding with good resistance to corrosion and abrasion, good thermal shock resistance, good spelling resistance, high mechanical strength, good volume stability under high temperature.
The mineral composition of heavy dense Clay Fire Bricks mainly is kaolinite(Al2O32SiO22H2O) and 6%~7% impurities (oxides of potassium, sodium, calcium, titanium and iron). The firing process of blast furnace refractory tiles is mainly due to the continuous dehydration of kaolinite to form crystallization of mullite (3Al2O32SiO2). SiO2 and Al2O3 in the yellow fire clay bricks form a eutectic low-melting silicate with impurities during the firing process, surrounding the mullite crystal.
The Clay Fire Bricks made by CH refractories with various size and free mold charge to meet different kiln applications. To be professional refractory blocks manufacturer since 1984, CH refractories also can design heat resistant bricks for sale, size according to your kiln drawing for free, and suggest you the most economical refractory bricks price for your kiln.
Clay Fire Bricks is one of the most widely used fire brick, which need large quantity, so price is important for customer. We will provide most competitive price for all of the customers. Our bricks has been widely imported to many countires, such as Malaysia, Indonesia, Pakistan and so on. Welcome to ask price directly.
