High Strength 230*114*65mm Hard Fire Brick High Temperature Brick Heat Proof Bricks

Hard Fire Brick

Kiln refractory Hard Fire Brick 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 Hard Fire Brick 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.

Hard Fire Brick maufactured by CH refractories is made from high quality bauxite,and make sure alumina content and bulk density. We only provide stable quality product.

Hard Fire Brick 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.
