1800℃ High-Alumina Premium Refractory Brick | Shijiazhuang Hongtao Technology

Shijiazhuang Hongtao Technology Co., Ltd., a professional high-tech enterprise based in Zhengding County, Shijiazhuang, Hebei, China, specializes in R&D, manufacturing and customization of 1800℃ high-alumina premium refractory bricks, core materials for high-temperature industrial kilns and equipment linings.

Our 1800℃ high-alumina premium refractory bricks are made of high-purity bauxite clinker and fused corundum, with Al₂O₃ content ≥85% and Fe₂O₃ ≤1.0%[1][8]. Produced via high-pressure molding (≥150MPa) and high-temperature sintering, they feature excellent high-temperature resistance, with long-term working temperature up to 1600℃ and short-term maximum temperature of 1800℃[4][8].

With a bulk density ≥2.75g/cm³, apparent porosity ≤18% and cold crushing strength ≥85MPa, they have superior thermal shock resistance and chemical inertness[1]. They resist corrosion from slags, acids, alkalis and molten metals, ensuring stable structure and no material contamination[3][7].

Widely applied in metallurgy, glass, cement and petrochemical fields—for blast furnace linings, glass furnace regenerators, cement rotary kilns and steel ladle linings[1][4][9]. They support standard and customized sizes, with Shijiazhuang Hongtao committed to providing high-quality, durable refractory solutions for global partners.
