2, Khoom Piav Qhia:
Cov lus qhia luv luv: Tsawg porosity schamotte cib yog cov av nplaum zoo, uas yog ua los ntawm cov pob zeb zoo uas tau muab hlawv pov tseg, zoo Calcined Bauxite lossis sillimanite hmoov, thiab cov av nplaum zoo. Tom qab kev tshawb fawb thiab tsim nyog, cov av nplaum tau tsim los ntawm kev nias nrog lub tshuab siab ntawm 630ton lossis ntau dua. Qhov ntsuas kub yog 1380-1450 ℃, Fe2O3 cov ntsiab lus ntawm cov khoom no qis, qhov porosity qis, lub zog siab, cov pa ntws yaig tsis kam thiab slag yaig kev ua haujlwm tau zoo, Nws muaj kev ruaj ntseg zoo hauv thermal poob siab tsis kam, thiab tau siv dav hauv chav ua cua sov iav cua txias chav, ladle, qhuav quenching coke qhov cub, petrochemical kev lag luam rauv, thiab lwm yam.
3, Ntim: Fumigation ntoo tais + ntawv tiv thaiv kaum + ncab zaj duab xis + yas yas siv, yooj yim rau txhua qhov kev thauj mus los
4, Yam khoom ua siab ntev: ≤100mm ± 0.5mm 200-300mm ± 1.5mm ＞ 300mm ± 2mm
5, Cov lus tawm tswv yim zoo ntawm kev siv cov khoom lag luam, cov khoom tau raug xa tawm mus rau Kaus Lim Qab Teb, Nyiv Pooj, Pakistan
6, Peb yog tus muab kev tshaj lij, leej twg tuaj yeem muab cov neeg siv khoom siv thev naus laus zis khoom siv dawb, siv thiab lwm yam teeb meem
