Malunga nezitena ezinyanzelayo zokukhuphela umbane ngokutshisa inkunkuma

Xa kukhethwa izitena ezitshintshiweyo zokutshisa izitofu, kufuneka kuhlawulwe kwiqondo lobushushu kunye nokudleka kwamalungu ahlukeneyo eziko, kwaye kunokukhethwa amabakala ahlukeneyo ezinto.

Ubushushu begumbi lokutsha, elilelo zone I, ngu-1400 ~ 1600 ℃, kwaye izitena zekorundum ezinomxholo wealuminiyam ezingama-90% zinokusetyenziswa; iqondo lobushushu elisebenzayo kwinxalenye ephezulu yeziko, oko kukuthi, kummandla we-II, yi-900 ~ 1000 ℃, ikhowuni ixhotyiswe ngemilomo engamanzi yenkunkuma, kwaye umxholo wealuminiyam ungaphezulu kwama-75%. embindini weziko, oko kukuthi ummandla we-III, yi-900 ℃, kunye netyuwa etyhidiweyo kunye nealkali zihamba ezantsi kwisithando somlilo, zibangela umhlwa omkhulu. Isitena sealumini ephezulu (LZ-65) sinokusetyenziswa; Kuyafana embindini wesithando somlilo, xa kukho ityuwa eninzi etyhidiweyo kwiimveliso zomlilo, kulula ukugxila kwithambeka, ukuhlala ixesha elide, kwaye kulula ukungena kwi-Refractory. Ukuba kukho i-Na2CO3, umhlwa ubaluleke kakhulu, ke mbi kakhulu kunombindi wesithando somlilo. Izinto ezixineneyo ezine-porosity esezantsi, ezinje ngeemveliso ezingaqondakaliyo ezinqabileyo.
