Fireclay Brick Good Abrasion Resistance Fire Clay Anchor Brick for Cement Kiln
Introduction:
Refractory anchor brick to fire brick containing Al2O3 more than 48%, which is made of high grade bauxite through high temperature calcinations. Fire clay brick is a kind of neutral refractory material so that it enjoys excellent resistance to acid and alkali corrosion.
Feature:
Fire clay brick has the feature of high refractoriness under load, which decide high alumina brick is a n ideal material for various kinds of industrial furnace.
Application:
Fire clay brick is widely used in building lining of hot-blast stove, blast furnace, coke oven, rotary kilns of cement and so on.
