What a blast furnace refractories generally?
Common refractories often use silica?brick, semi-silica brick, fireclay brick, high alumina brick, magnesia brick, etc. special materials often used are AZS brick, corundum brick, directly bonded magnesia-chrome brick, carborundum brick, silicon nitride bonded silicon carbide bricks, nitrides, silicides, sulfides, borides, carbides and other non-oxide refractory materials; calcium oxide, chromium oxide, aluminum oxide, magnesium oxide, beryllium oxide refractory insulating refractory frequently used. material diatomite products, asbestos products, insulation boards. monolithic refractories have fettling frequently used, refractory ramming mixes, refractory castable, fire-resistant plastic, refractory clay, refractory gunning refractory projection material, refractory coatings, lightweight refractory castable, stemming etc.
Usually metal anchorage plus wear-resistant refractory spray paint. at the middle part we use high alumina bricks, corundum bricks. high duty refractory is important in improving bosh furnace lining.
refractories for blast furnace include carbon brick and silicon-aluminum refractory. BF carbon brick inlcudes half-carbon charcoal bricks, microporous charcoal brick, ultra porous charcoal bricks, graphitic brick and mould pressing charcoal brick. tiles and molded graphite small charcoal bricks. I hope my answers above are helpful to you and your ideal anwers.
