Refractory Bricks Manufacturer

Refractory castables are widely used in metallurgy, nonferrous metals, building materials, electric power, petrochemical, and other industries. It is a more commonly used unshaped refractory. Low cement castables, by definition, are refractory castables with low cement content. Low Cement Castable in Rongsheng Advantages of Low Cement Castables The performance of low cement refractory castable is better than traditional refractory castable. It not only reduces the amount of cement. Moreover, it adopts ultra-fine powder technology and a reasonable proportion of aggregate distribution. It is a castable prepared by using comprehensive technical measures such as highly effective active additives. Compared with traditional refractory castables, low cement castables have high density, low porosity, and higher curing strength at room temperature. Good volume stability. After drying and calcination, the volume shrinkage is small. Several Common used Low Cement Casta

Refractory spray coatings and refractory repair materials are both of the unshaped refractories. Compared with refractory castables, they differ greatly in construction methods. Both refractory materials belong to the unshaped refractory materials with fast construction progress and short furnace repair time. Refractory Repair Material Refractory repair materials are refractory materials used to repair furnaces and thermal equipment. Refractory repair materials are classified according to usage. There are many varieties of refractory repair materials, including refractory spray coating material, melt injection spray supplementary material, refractory cast supplementary material, refractory pressure feed material, refractory pump injection material, and refractory grouting material. The construction methods of refractory repair materials include spraying, feeding, pressing, pumping, or grouting. Among them, there are many spraying methods for refractory repair materials, whic

The main component of the light-weight special acid- proof  brick is silica, which forms a large amount of mullite under high-temperature firing, which is a substance with high acid resistance. Because the acid- proof brick has a compact structure and low water absorption, it can also withstand any concentration of alkaline medium at room temperature, but it is not resistant to molten alkali with high temperature. The high-temperature resistance of light-weight special acid- proof bricks can reach above 1200℃. Lightweight Acid Proof Brick Characteristics and A pplication of A cid- proof B rick s The acid-resistant brick contains more than 70% silica and is sintered. In the chemical industry, it is mostly used in the construction of acid trenches, acid wells, acid storage tanks, and large acid-carrying impact surfaces. Acid- proof bricks are made of high-quality high-silicon acid-resistant materials through fine processing. It has good acid resistance, small size,
