Shangzhuang Refractories Co., Ltd., Zhengzhou City, tell us something about refractoriness, refractoriness of not less than one kind of inorganic non-metallic materials 1580 ℃. Refractoriness refractory cone specimen means in the absence of a load case insulation brick acid brick, resistant to high temperatures without melting down the softening temperature in Celsius. Refractory materials are widely used in industry metallurgy, chemical, petroleum, machinery manufacturing, silicates, power, etc., the largest amount in the metallurgical industry, accounting for 50% to 60% of total output. Refractories and high temperature insulation bricks technology accompanied by the emergence acid brick, roughly originated in the mid-Bronze Age. China Eastern Han Dynasty porcelain kiln firing has done saggar timber and clay refractories. Early 20th century, refractory to high-purity, high density and ultra-high temperature product direction, at the same time there has been complete without firing a small energy monolithic refractories and refractory fibers. Modern insulation brick acid brick, with the development of atomic energy, space technology, new energy technologies, with high temperatures, corrosion resistance, thermal shock resistance, erosion and other comprehensive excellent performance refractories has been applied.
