Blast furnace with important impurity compounds clay brick in iron, titanium compound. From the combined air reheating resolutely brick white actually can surmise, firing air and iron, titanium compounds are those conditions. However, iron, titanium compound coexist with single exist, have different effects on the brick body staining. Titanium photon single exist, dyeing is not outstanding, but the blast furnace clay brick even in the combined air brick body slightly blue, while the iron photon single exists, the brick body orange and maroon.
Silicon carbide brick: one thousand eight hundred high temperature Baidu, refractoriness under load, thermal expansion coefficient, good thermal shock resistance are good for cooling zone and kiln. Corundum Mo 2: thermal shock resistance, high strength, good wear resistance, suitable for transition zone. Zirconium containing refractory brick: refractory fireclay brick contains a few ZrO, in the heating process of martensite phase transformation attacks constitute fine cracks, clay brick with strong alkali resistance, spalling resistance and slag resistance is good.
