SK32 SK34 SK36 SK38 refractory brick are alumina silicate bricks contain 35-40% alumina. The bricks are made from various raw material s of fire clay, calcined chamotte, soft clay. We manufacture bricks using thorough quality control. Shapes and properties depend unpon sevice conditions, becuase the bricks have low porosity, high strength, good resistance to thermal spalling and abrasion and to creep, they are applied for the linings of various incinerators, reheating furnaces etc.
SK32 SK34 SK36 SK38 refractory brick is made of local top grade fireclay materials under the high temperature according to the lasted national standard, which possesses even bulk density, high strength, low thermal conductivity and low impurity.

Raw Material Selection High Temperature Fire Resistant insulation refractory fire clay fire bricks
To ensure the quality of our raw materials, we only purchase our raw materials from our long-term trusted suppliers. With every purchase, the raw material must be passed 2 times inspection, 1 time at our supplier's site. a second inspection on the batch after the material arrived to our factory. Each time raw materials enter our facility, they are inspected again prior to being accepted.
