Zhengzhou City shangzhuang Refractories Co. (www.yntjj.com.cn) is located in Zhengzhou City, Henan Province, Zhengzhou Xinmi shangzhuang Industrial Development Zone, Contact: Cheng Haitao Refractories Co., Ltd., Zhengzhou City shangzhuang understand some materials, such as silica-alumina refractory products, it is generally believed that at a certain temperature (e.g., within the following 700 ~ 900 ℃ elastic range) chemical furnace refractories, the higher the temperature wear (Wear resistance), the lower, can be considered when the temperature is increased after With the increase of elastic modulus, abrasion resistance (Wear resistance) decreased. When the temperature rises, reaches a maximum elastic modulus after, with the decrease of the elastic modulus, abrasion resistance (Wear resistance) but improved. Aluminosilicate refractory products such as during 1200 ~ 1350 ℃, abrasion or even better than those at room temperature. When the temperature is further increased, reaching more than 1400 ℃, the result of refractory products in liquid viscosity drastically reduced wear (Wear resistance) decreases. Some quality refractory products such as chromium, with increasing temperature, wear (Wear resistance) increases. Refractories Co., Ltd., Zhengzhou City shangzhuang different from the general understanding of refractory materials chemical furnace refractories, which is the base material for high-temperature technology services, you must have damaged and difficult to use in the harsh conditions of high temperature performance. Our annual output of more than 600 million tons of refractory materials, steel consumption of 130 kg per tonne of refractories, this value of 3 to 6 times higher than the advanced industrial countries. As the steel industry continues to adopt new technologies, advanced production equipment steel production of refractories physical and chemical properties and dimensional requirements more stringent targets. Under certain conditions, the refractory quality, variety and progression of new technologies for the iron and steel smelting and even plays a key role. Therefore, to achieve the modernization of the metallurgical industry, we must pay attention and develop refractory technology. Refractories Co., Ltd., Zhengzhou City shangzhuang importance refractory production, quality assurance, excellent price guarantee to meet the customer's consumption needs.
