Refractories Co., Ltd., Zhengzhou City shangzhuang understand refractory wear depends on the composition and structure of the material. When the material is dense polycrystal composed of a single crystal, the wear resistance depends on hardness of the constituent material of mineral crystals. High hardness, high wear resistance. When the mineral crystal for unusual sexual, fine grain, high wear resistance. When the material consists of multi-phase composition, its wear resistance is also directly related to the bulk density or porosity of the material, also in connection with the classification of the relevant group. Thus, at room temperature for a certain kind of refractory material is concerned, the wear resistance is proportional to its compressive strength, the sintered article of good abrasion resistance is also good. The wear resistance of refractory products related to temperature. Shangzhuang Refractories Co., Ltd., Zhengzhou City, learned on the basis of the common refractory first is the development and application of refractory oxide material, it has started to develop custom-shaped brick castable in the early 20th century to the beginning of the 1930s There are products on the market and the sale of goods. Oxide material in the early development of custom-shaped brick castable, mainly the production of components and smelting temperature resistant Gao dilute precious metal used in special occasions crucible material. In a later development, gradually found their addition to the high temperature properties, but also has many other excellent performance at high temperatures: such as excellent mechanical strength, wear resistance, erosion, corrosion resistance, chemical resistance, molten metal corrosion, anti- oxidation, electrical insulation and the like. Castable custom shaped brick, shangzhuang refractory castable custom shaped brick by shangzhuang Refractories. Zhengzhou City shangzhuang Refractories Co. (www.yntjj.com.cn) in carbon brick, high alumina bricks, clay brick, castable, acid brick, alkali brick, custom shaped brick, and other industries have a higher visibility , credit management, both quality of service, welcome to inquire, or consult our "business alliance customer service," it!
