Refractory fire bricks for bbq

Specifications

fireclay brick series:SK-32, SK-34, SK-36, HA-60, HA-70, HA-75
Standard size: 230x114x65/75mm

 

Fireclay bricks is Al2O3 content of 30% to 40% aluminum silicate clay material products, With 50% clay and 50% soft hard clay clinker, As the size requirements for certain ingredients, after forming, drying, firing at a high temperature of 1300 ~ 1400 ℃. includes standard brick, common brick, special-shaped brick. They are widely applied in coke oven, blast furnace, air stove, molten steel ladel, gating system, boiler, cement kiln, glass kiln, kinds of kiln lining and thermal equipment

                                                                 

Fireclay bricks can be classified Light and heavy clay brick, the difference of heavy fireclay is based on the number of alumina content. Light clay is based on density and bulk. Different part of kiln use different fireclay.
