Refractories Co., Ltd., Zhengzhou City shangzhuang different from the general understanding of refractory materials Refractory offer, it is the basic 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 distributor refractories, steel production of advanced production equipment, physical and chemical properties and dimensions for refractory index of more stringent requirements. Under certain conditions Which refractories, 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. Refractories Co., Ltd., Zhengzhou City shangzhuang learned refractory mechanical strength is the maximum stress in the material under the action of external mechanical force to destroy can bear. Such mechanical force may be caused by refractory pressure, tension, breaking force, shear force, impact force, corresponding to the strength of the material referred to compressive strength, tensile strength, flexural strength, shear strength, impact strength . Special refractories, most materials having a relatively Gao room and high temperature mechanical strength, but compared with the metal material, the impact strength is very low due to brittleness. The main factors affecting the mechanical strength of the refractory are: grain size, density and porosity of the material, the material is subjected to a temperature.
