Njerwa zopumira komanso zida zokongoletsera zazitsulo

Zomwe njerwa zopumira zomwe zimagwiritsidwa ntchito ndi mafakitale opanga zitsulo ndi corundum, spinel, ndi zina zambiri, ndipo gulu lalikulu lomwe lili ndi Al2O3 (zili ndi ≥90%), komanso mulinso MgO ndi Cr2O3. Ntchito ya njerwa yopumira ndi kuchotsa zonyansa (zinthu zosafunikira, mpweya, ndi zina) muzitsulo zosungunuka ndikuwonjezera kutentha kwazitsulo. Ma ladle ena ndi njerwa zopumira kawiri, momwe pachimake chopumira chimatha kusinthidwa.

(Chithunzi) Njerwa zoduladula zopumira

Tundish ndi chidebe chotsitsimula. Nthawi zambiri, chida chogwiritsira ntchito chomwe chimagwiritsidwa ntchito ndi opanga zitsulo chimagwiritsidwa ntchito kuthana ndi kugwa kwa chitsulo chosungunuka pambuyo poti njira yolira ya argon ndiyotsika. Choyambirira, chitha kulandira chitsulo chosungunuka kutsanulira kuti muchepetse mphamvu yazitsulo zosungunuka. Buffering ikamalizidwa, idzagawidwa ku nkhungu iliyonse kuchokera pamphuno. Izi sizothandiza kokha pakukhazikika ndi kudalirika kwa kuyeretsa kwa ladle, komanso zimapindulitsa pazinthu zakuthupi ndi zamankhwala zachitsulo chosungunuka. . Tundish makamaka imagwira ntchito yochepetsera kupsyinjika, kukhazikika kwa bata, kuchotsa inclusions, kusunga, ndikupatutsa chitsulo chosungunuka. Zipangizo zokometsera tundish ndizophatikizira mbale, zoteteza, kupumira kolowera madzi, slag yosungira nyumba zolowera, ndi zina zambiri.

Zofanana ndi zomwe njerwa zodulira mpweya, Zida zopangidwa ndi opanga zopangidwa ndi corundum, ndi zina zambiri, komanso zimakhala ndi magnesium oxide yambiri. Pali mitundu itatu yayikulu yofanana ya homogeneity ya corundum Al2O3, yomwe ndi α-Al2O3, β-Al2O3, ndi γ-Al2O3. Kuuma kwa corundum kuli chachiwiri kwa diamondi. Corundum imagwiritsidwa ntchito makamaka pazida zapamwamba kwambiri, ulonda ndi makina osanja omwe amakhala ndi zida. Kristalo wopangira wa Ruby ngati laser yotulutsa zinthu. Ma rubies ndi miyala ya safiro onse ndi mchere wa corundum. Kupatula momwe nyenyezi zimawunikira, ma corundum owoneka bwino owala okha ndi omwe angagwiritsidwe ntchito ngati miyala yamtengo wapatali. Mtundu wofiira umatchedwa ruby, pomwe mitundu ina ya corundum yonse amatchedwa safiro mu bizinesi.

Njerwa zodumanira ndi mpweya ndipo zida zopangira zida ndizofunikira kwambiri kwa opanga zitsulo ndipo ali ndi gawo losasinthika. Firstfurnace@gmil.com, monga katswiri wopanga njerwa zopumira, wapanga njerwa zopumira kwa zaka 18. Ili ndi chidziwitso chambiri, ukadaulo wapamwamba, chilinganizo chovomerezeka, kapangidwe kapadera, zida zotsogola kutsogola ndi ukadaulo woyamba kupanga, ndipo imatha kupanga seti 120,000. Wopanga wamkulu kwambiri mdziko muno wa zida zowombera ndi kuwombera za argon.
