Refractories Co., Ltd., Zhengzhou City shangzhuang take you to understand refractories in China's development: the ancient, medieval, Renaissance refractories, industrial revolution around the blast furnace, coke oven, stove refractories, refractory materials and the new post-modern times Its manufacturing process, modern refractories manufacturing technology and main technical progress and prospects for the future development of refractories, 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. Early 20th century, high alumina brick castable refractory to high-purity, high-density and ultra-high-temperature products, direction, at the same time there has been complete without firing a small energy monolithic refractories and refractory fibers. Modern technology 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. Refractories in constant development, we shangzhuang Refractories Co., Ltd., Zhengzhou City, has also been progress in high-alumina clay casting material, hoping to meet the needs of more customers. Refractories Co., Ltd., Zhengzhou City shangzhuang understand the production process according to the extent and shape dense products different sintering method, casting method and melt blowing method. Sintering is part of the pre-firing clinker raw material, crushing and screening, then a certain proportion of the raw material mix of high alumina clay casting material, after forming, drying and firing. The purpose of the pre-burning material which is moisture, organic impurities, sulfate decomposition of gas burning to reduce high alumina brick firing shrinkage products castable to ensure the accuracy of product dimensions. After crushing and grinding of raw materials also need to go through screening, because the powder material consisting of different size were graded, you can ensure that the most closely packed to obtain dense bodies. Castable high alumina brick, high alumina brick castable refractory shangzhuang provided by shangzhuang Refractories. If you have any questions or consult this information, please contact us now!
