Zofunikira zotsatirazi zimayikidwa patsogolo pa zida zopangira khoma la ng’anjo:

1. Kukana kokwanira

Refractoriness ake ayenera kukhala 1650 ~ 1780 ℃, ndi kufewetsa kutentha ayenera kukhala apamwamba kuposa 1650 ℃.

2. Kukhazikika kwamafuta abwino

Kutentha kwa khoma la ng’anjo kumasintha nthawi zonse, ndipo khoma la ng’anjo nthawi zambiri limang’ambika chifukwa cha kutentha kosafanana, zomwe zimachepetsa moyo wautumiki wa khoma la ng’anjo. Chifukwa chake, ngati chotchingira pang’anjo yamagetsi, iyenera kukhala ndi kukhazikika bwino kwamatenthedwe.

3. Kukhazikika kwamankhwala

Kukhazikika kwamankhwala kwazinthuzo kumagwirizana kwambiri ndi moyo wa khoma la ng’anjo. Zida zopangira khoma la ng’anjo siziyenera kukhala ndi hydrolyzed ndikusiyanitsidwa ndi kutentha kochepa, ndipo siziyenera kuwonongeka mosavuta ndi kuchepetsedwa kutentha kwakukulu. Siziyenera kukhala zophweka kupanga zinthu zochepa zosungunuka ndi slag panthawi ya smelting, ndipo siziyenera kuchitapo kanthu ndi zitsulo ndi zowonjezera zowonjezera, ndipo sizidzaipitsa zitsulo. .

4. Coefficient yaing’ono yowonjezera kutentha

Voliyumu iyenera kukhala yosasunthika ndi kusintha kwa kutentha, popanda kukulitsa komanso kutsika.

5. Ali ndi mphamvu zamakina apamwamba

Iyenera kukhala yokhoza kupirira kutulutsidwa kwa chiwongoladzanja mu kutentha kochepa; chitsulo chikakhala chosungunuka kutentha kwambiri, chiyenera kupirira kupanikizika kwachitsulo chosungunuka ndi mphamvu yamphamvu yamagetsi yamagetsi; kuvala kukana ndi kukana dzimbiri pansi pa kukokoloka kwa nthawi yayitali kwachitsulo chosungunuka.

6. Ntchito yabwino yotchinjiriza

Kuyika kwa khoma la ng’anjo sikuyenera kuyendetsa magetsi pa kutentha kwakukulu, mwinamwake kungayambitse kutayikira ndi maulendo akanthawi, kuchititsa ngozi zoopsa.

7. Ntchito yomanga zinthuzo ndi yabwino, yosavuta kukonza, ndiko kuti, ntchito ya sintering ndi yabwino, ndipo nyumba yopangira ng’anjo ndi yokonza ndi yabwino.

8. Zinthu zambiri komanso mtengo wotsika.
