Corundum brick is a kind of high alumina refractory bricks, and mainly produced and applied as special refractory mateirals in extreme working conditions. Corundum brick is made of high purity fused alumina powder, white fused alumina oxide or tabular alumina, adding with other binders like refractory clays, reactive alumina powder, and high purity silica. Corundum bricks are calcined at high temperatures to form a matrix with mullite, mullite-corundum or corundum, which making corundum brick with excellent volume stability structure and service temperature can be reach to 1900°C.

Clay refractory bricks are the most widely used refractories made from chamotte clay minerals and calcined at a high temperature of 1300 to 1400 ° C.. It can be easily located out in the nature and contains suitable content ratio of silica, cyanite and alumina. Fire clay bricks have low porosity and are durable for various re-heating process.

Calcium Silicate board , also known as the porous calcium silicate board, is a fiber-reinforced calcium silicate board, with silicon oxide, calcium oxide, and the reinforcing fibers as the main raw materials, The products are made by stirring, heating, gelling, forming, pipe hardening and drying. processes. Calcium silicate board is a new type of rigid insulation material. calcium silicate board main material of the products are SiO2 43%, CaO 44% and reinforcing fiber. With light bulk weight, Low thermal conductivity and high bending and compressive strength character, using in construction.Petroleum, electric power and Building partition wall, curtain wall, roof and building envelope thermal insulation

JM23 insulation brick is color of white insulating fire brick, with light Weight, based on aluminum silicate refractory materials. It’s made from high-purity refractory clays with graduated additions of alumina for applying in higher temperature working conditions. JM23 insulation brick with different bulk density from 0.6g/cm3~1.2g/cm3.

Monolithic refractory castable cast-in-site is time-consuming and labor-intensive and requires the guidance of a professional technician. Thus, Precast shapes are a better choice and widely used by the cement, the steel plant, and the molten aluminum industry in recent years. Due to the complex parts of some industrial kilns and thermal equipment, the cost of refractory brick products is relatively high. SIJIHUO REFRACTORY produces precast shapes with low and ultra-low cement content refractory materials, such as mullite, corundum, corundum coordinate mullite, Silicon Carbide, etc. We insist on creating superior custom-engineered Precast Shapes and a wide variety of materials to withstand the critical demands for industries and provide tailored solutions to meet our customers` requirement
