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 kiln refractory bricks, refractory materials, refractory to high-purity, high-density and ultra-high-temperature furnace product direction firebrick, refractory materials, while there has been complete without burning, low energy consumption of monolithic refractories and fire-resistant 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. In the development of refractory firebrick kiln refractory material, we shangzhuang Refractories Co., Ltd., Zhengzhou City, also continue to progress, I hope to meet the needs of more customers. 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 formed of pressure, tension, breaking force, shearing force, impact force caused by the furnace refractory bricks, refractory material, 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.
