Zhengzhou City shangzhuang Refractories Co. (www.yntjj.com.cn) is located in Zhengzhou City, Henan Zhengzhou Xinmi shangzhuang Industrial Development Zone, Contact: Cheng Haitao shangzhuang Refractories Co., Ltd., Zhengzhou City, tell us something about refractoriness refractoriness of not less than 1580 ℃ for a class of inorganic non-metallic materials. Refractoriness refractory cone specimen means in the absence of a load, the resistance 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 technology accompanied appears 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, 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 Co., Ltd., Zhengzhou City shangzhuang learned refractory recycling of waste refractory material on successfully recovered and reused many issues must be considered. These issues include: the type and quantity of waste refractories, users and producers of refractory insulation bricks location acid brick, acid brick healthy relationships insulation bricks, insulation tiles acid brick pollution problems, the value of the material (including the elements contained value and processing costs), separation, selection of economic problems. In short, the refractory recycling should both meet the company's overall recovery plan and should be the simultaneous development of recycling other materials. Recycling of other materials include: waste minimization and measurement products in situ recycling.
