It is widely used as the lining material of industrial furnaces such as residual oil gasifiers, coal gasifiers, carbon black reaction furnaces, pulp waste gasifiers, etc. Rongsheng refractory brick manufacturer is a manufacturer of high-quality high-purity … Read more
Anti-flaking high-alumina bricks are fired refractory bricks made of special-grade high-alumina bauxite clinker and ZrO2-containing components, which are made by high-pressure molding according to a specific ratio. Anti-stripping high-alumina bricks have strong anti-stripping ability, high refractoriness, good cracking resistance, and strong corrosion resistance. At the same time, it also has the properties of anti-corrosion of … Read more
The fused refractory is made by melting the precisely prepared mixture in an electric arc furnace, then pouring it into a sand mold, and the ingot is heat-treated before machining. The smelting process can obtain complete coarse crystals and dense structures. Compared with sintered refractories, it has the characteristics of compact structure, low porosity, high … Read more
High alumina fire bricks belong to aluminum silicate refractories and are called neutral refractories according to their chemical properties. They are the most widely used refractory bricks in the refractory industry. High-alumina bricks have the advantages of small creep at high temperatures, strong slag resistance, strong erosive corrosion resistance, and good thermal shock stability. Therefore, … Read more
