Introduction of high alumina wear resistant castable refractory
A high alumina raw material is used as an aggregate and a powder, and a refractory castable made of a binder is added. It has high mechanical strength and good resistance to thermal shock and abrasion. It is mainly used as the lining of various kiln such as boiler, blast furnace, hot blast stove, reheating furnace and ceramic kiln.
High-alumina wear-resistant castables refractory are widely used in hardware, smelting, chemical, non-ferrous metals and other industries, especially in the steel industry, and are mainly used in the front kiln mouth, disintegration furnace, kiln hood and other parts of the rotary kiln.
High alumina wear resistant castables refractory are classified into conventional and low iron and ultra low iron. Nowadays, it is important to use low iron type on heavy steel, while ultra low iron type high alumina castable refractory is used in metallurgical furnace of non-ferrous industry.
Low iron high alumina castables refractory and ultra low iron high alumina castables refractory also have good water consumption and fluidity function during construction, high early intensity after construction, high density, early stripping and short curing time. Therefore, the selection of high alumina castables refractory requires a qualitative number for the part, which reduces the cost and makes the part take a long period.
High alumina wear resistant castables refractory are based on the traditional proportioning, adjusting the particle grading, adding different admixtures, reducing the amount of cement, improving performance, increasing the medium temperature strength and refractoriness under load, reducing the thermal conductivity, good thermal stability. It has anti-penetration, erosion resistance, impact resistance, wear resistance, good mechanical properties, strong furnace structure integrity, air tightness superior to brick furnace, extended furnace life, saving furnace cost and significant economic benefits. High strength and high alumina wear resistant castables refractory are widely used in power station, boiler, melting furnace, reheating furnace, soaking furnace, heat treatment furnace and induction furnace.
