SK-30 SK-32 High Alumina Refractory Bricks For Hot Blast Furnace Stove
High Alumina Refractory Firebrick for Industrial Furnace Construction refers to fire brick containing Al2O3 more than 38%, which is made of high grade bauxite through high temperature calcinations.
It is is a kind of neutral refractory material so that it enjoys excellent resistance to acid and alkali corrosion. It has characteristic of high refractoriness under load, which decide high alumina brick is a n ideal material for various kinds of industrial furnace. It is widely used in building lining of hot-blast stove, blast furnace, coke oven, rotary kilns of cement and so on.
1. Iron & steel making industry: Blast furnace, hot blast furnace(stove), pellet shaft furnace, hot metal ladle, steel ladle, tundish, heating furnace, soaking pit furnace, heat treatment furnace, refining furnace, reheating furnace, metal mixter furnace, annealing furnace, cupola furnace, electric arc furnace, induction furnace, AOD furnace, VOD furnace,etc thermal technology equipment.
