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 refers refractory cone sample at no load conditions, resistance to high temperatures without melting down of the Celsius temperature to soften. Refractory materials are widely used in metallurgy industry, chemical industry, petroleum, machinery manufacturing, silicates, power, etc., the largest amount in the metallurgical industry, accounting for 50% to 60% of total output. Refractory and high temperature technology came along, generally originated in the mid-Bronze Age. China Eastern Han Dynasty porcelain kiln firing has done sagger clay material and refractories. Which is good in the early 20th century, refractories, refractory to high-purity, high-density and ultra-high temperature refractory products sales direction, at the same time there has been complete without burning, low energy consumption of monolithic refractories and refractory fibers. Modern refractories, with the development of atomic energy technology, space technology, new energy technologies, with high temperatures, corrosion resistance, thermal shock resistance, erosion and other comprehensive excellent performance refractories has been applied. Shangzhuang Refractories Co., Ltd., Zhengzhou City, learned basic refractories main varieties: magnesia-chrome brick, brick, brick spinel, dolomite bricks. Magnesia-chrome brick is divided into ordinary magnesia-chrome brick, magnesite-chrome brick combined direct, semi-direct combination of magnesia-chrome brick. Basic refractories primarily used in cement kilns burning zone, transition zone and kiln site. In particular, spinel brick lining material has become one of the major large-scale cement kiln kiln, its use in the transition zone, and gradually the use of the cooling zone, kilns, even for the firing zone. Basic refractories, thermal shock resistance are poor, only a few times. Wholesale refractories in use, the key is to be able to hang kiln skin. Just keep proper kiln thick skin (200 ~ 300mm), will be able to compensate for the lack of basic refractories poor thermal shock resistance. Spinel brick To promote the use of the firing zone, should also solve the problem of skin hanging kiln. Which is good refractories | shangzhuang Refractories (certified) | Chongqing refractory provided by Zhengzhou City shangzhuang Refractories Limited. Zhengzhou City shangzhuang Refractories Co.
