Refractory zvidhinha kupatsanura:

1. Maererano negadziriro yekugadzirira, yakakamurwa kuva: zvidhinha zvinopisa, zvidhinha zvisingasviki uye zvidhinha zvakasanganiswa

2. Zvinoenderana nehukuru uye chimiro chezvidhinha zvinoramba, zvinogona kukamurwa kuita zvidhinha zvakajairika, zvidhinha zvine chimiro chakasarudzika, uye zvidhinha zvakashongedzwa.

3. Maererano nezviri mukati mezvinyorwa zvezvidhinha zvinoramba: zvidhinha zvesilika, semi-silica zvidhinha, zvidhinha zvevhu, zvidhinha zvakakwirira zvealuminium, mullite zvidhinha, zvidhinha zvecorundum, aluminium carbon brick, carbon brick, silicon carbide zvidhinha, aluminium silicon carbide zvidhinha. , aluminium carbide Silicon carbon zvidhinha, alumina-magnesia spinel zvidhinha, magnesia-aluminium spinel zvidhinha, magnesia zvidhinha, dolomite zvidhinha, magnesia-calcium zvidhinha, aluminium-zirconium zvidhinha, nezvimwewo.

4. Maererano ne acidity uye alkalinity yezvidhinha zvinoramba: acid refractory zvidhinha, neutral refractory zvidhinha uye alkaline refractory zvidhinha.

5. Maererano nekushisa kwekushandiswa, inogona kupatsanurwa kuva: zvidhinha zvevhu, zvidhinha zvevhu, zvidhinha zvakakwirira zvealuminium, zvidhinha zvepamusoro zvealuminium, silica zvidhinha, corundum zvidhinha, magnesia zvidhinha.
