Chii chinonzi classification zvidhinha zvinopesana?

Zvinoenderana nekuumbwa kwayo, inogona kukamurwa kuita zvikamu zvishanu, zvinoti: silica-alumina zvidhinha zvinofuratira, alkaline refractory zvidhinha, carbon-ine refractory zvidhinha, zirconium-ine refractory zvidhinha, uye kupisa-insulatory refractory zvidhinha.

Zvinoenderana neiyo PH kukosha, inogona kukamurwa kuita

(1) Iyo acidic refractories inonyanya kuumbwa nesilika, iyo inowanzoshandiswa mu silica zvidhinha uye zvidhinha zvevhu.

(2) Neutral refractories inonyanya kuumbwa nealumina, chromium oxide kana kabhoni;

(3) Alkaline refractories inonyanya kuumbwa ne magnesium oxide uye calcium oxide, uye magnesia zvidhinha zvinowanzoshandiswa.
