The mineral composition of heavy dense fire clay bricks mainly is kaolinite(Al2O3·2SiO2·2H2O) 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 (3Al2O3·2SiO2). 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 kiln refractory burner blocks 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.

The high strength castable refractory steel fiber reinforced wear-resistant castable is prepared by adding special grade aluminum bauxite clinker or corundum as aggregate and powder, adding binder, admixture and heat-resistant stainless steel fiber.
The ladle shroud is a refractory material which connects the steel ladle with the tundish. The ladle shroud has the functions of stabilizing the flow state of liquid steel, preventing liquid steel from oxygenation and splashing.
The tap hole clay is used to block the taphole plays an irreplaceable role in ensuring stable and high production of the blast furnace, improving the working strength and environment before the furnace, and prolonging the service life of the blast furnace.
