Izixhobo zokumelana ne-cupola

I-cupola yintsimbi yokwenza i-iron okanye i-oven-frying frying, kwaye umsebenzi wayo oyintloko kukwenza isinyithi. Ubushushu obusebenzayo yi-1400 ~ 1600 ℃. Umzimba wesithando somlilo wahlulwe phantsi kwesithando somlilo, umzimba wesithando somlilo, i-forehearth kunye nebhulorho.

I-bottom of the cupola idibene ngokuthe ngqo kunye nentsimbi eshushu etyhidiweyo kwaye ithwala ubunzima bayo yonke intlawulo. I-ASC ramming material okanye i-carbon ramming material kufuneka isetyenziswe kule nxalenye ukunceda ukuphucula ubomi be-cupola ezantsi.

Umgangatho ongaphezulu wokusebenza womzimba wesithando somlilo uchaphazeleka ngoomatshini kwaye unxitywe ngexesha lokutshaja. Yakhiwe ngezitena zentsimbi ezimile okwefeni, yaye icala elingaphandle lenziwe ngesanti yequartz.

Uluhlu olusebenzayo lwecandelo elisezantsi lomzimba wesithando somlilo, indawo yokutshisa i-coke kwi-tuyere nangaphezulu iphezulu kakhulu kwiqondo lokushisa, kwaye iphantsi kokhukuliseko lwe-slag, ukukhukuliseka kokuhamba komoya kunye nokutshatyalaliswa. Apha, izitena ze-chrome-resistant-resistant magnesia okanye izitena ze-magnesia zisetyenziswa.

Umoya we-oxidizing womsebenzi ophantsi womzimba wesithando somlilo uyancipha, kwaye i-ASC ye-ramming material iyasetyenziswa. Ezinye iindawo zesithando somlilo ziphantsi kweqondo lokushisa, ngoko izitena zodongwe okanye izitena ze-semi-silica zisetyenziswa. Umaleko osisigxina okanye i-insulation layer ye-furnace body yenziwe ngezitena zokugquma ukukhanya kodongwe.

Sebenzisa izitena zodongwe okanye izitena eziphezulu ze-alumina kwindawo yangaphambili kunye neebhulorho ze-cupola, kwaye usebenzise i-ASC ye-ramming material yenxalenye edibene nentsimbi etyhidiweyo; sebenzisa i-ASC ye-ramming material enomxholo ophezulu we-silicon carbide, iindawo ezenziwe ngaphambili okanye izitena eziphikisayo zenxalenye edibanisa ne-slag; Sebenzisa izitena zodongwe okanye izitena zodongwe ezikhaphukhaphu zokugquma okanye iileya ezisisigxina.

Ngokubanzi, ngaphantsi kwesithando somlilo sisebenzisa izinto zekhabhoni, izitena zodongwe, kunye nezixhobo zokukhwela i-ASC, umbindi wesithando somlilo usebenzisa i-magnesia chrome izitena, izitena ze-magnesia, izitena ze-corundum, kunye nezitena zodongwe, umphezulu womzimba wesithando somlilo usebenzisa i-hollow. izitena zentsimbi, kunye nenxalenye engezantsi yomzimba wezitena zodongwe, izitena ze-ASC, izixhobo ze-ASC ze-ramming, i-ASC preforms, i-ASC preforms ye-slag outlet, izixhobo ze-ramming ze-ASC, kunye nodaka lwe-ASC olusemgangathweni kunye ne-ASC preforms yokuphuma kwentsimbi.

Izitena zodongwe ze-forehearths, iibhulorho, iileya ezisisigxina, izitena ze-ASC, izitena zodongwe ezikhuselayo ezinobunzima bomgangatho osisigxina okanye i-insulation layers.
