Ndeipi misiyano pakati zvidhinha zvinopesana nezvidhinha zvitsvuku?

1. Raw zvinhu uye maitiro ekugadzira

1. Refractory zvidhinha

Refractory zvidhinha zvinhu zvinoramba zvakagadzirwa nevhu refractory kana zvimwe zvigadziriso zveraw, izvo zvinopenya yellow kana brown. Inonyanya kushandiswa kuvaka mabira ekunyungudutsa uye inogona kumira kutonhora kwakanyanya kwe1,580 ℃-1,770 ℃. Inonziwo firebrick.

2. Zvidhinha zvitsvuku

Mukugadzirwa kwezvidhinha, moto mukuru unowanzo shandiswa kupisa zvidhinha mukati nekunze, uye wodzima moto kuitira kuti hovhoni nezvidhinha zvitonhorese. Panguva ino, mhepo iri muchoto inoparadzirwa uye okisijeni yakakwana, ichiita mhepo yakanaka ye oxidizing, kuitira kuti chinhu chesimbi muzvidhinha chive ne oxidized mu iron trioxide. Sezvo iron trioxide yakatsvuka, ichaitawo tsvuku.
