Sebenzisa izikhathi ze izitini eziphefumula– i-refractory lining for ladle

Izitini ezivumayo zisetshenziswa enqubweni yokwenza insimbi ye-ladle futhi zinesikhathi esithile sokuphila, futhi i-ladle ngokwayo inomkhawulo wokuphila. I-Ladle, eyaziwa nangokuthi i-ladle, i-ladle, ne-ladle enkulu, iyithuluzi elishisayo elibalulekile labakhiqizi bensimbi, elakhiwe ikakhulukazi igobolondo, ulwelwesi oluphikisayo, kanye nomshini we-nozzle oshelelayo. I-ladle yenza imisebenzi yenqubo efana nokucwenga insimbi encibilikisiwe. Ukusetshenziswa kwe-ladle lining kuthinta ngokuqondile ukukhishwa kwensimbi. Ngakho-ke, ekuphishekeleni ukuthuthukiswa okuqhubekayo kokuphila kwe-ladle ngaphansi kwesisekelo sokuqinisekisa ukusetshenziswa okuphephile, kuyadingeka ukunciphisa ukusetshenziswa kanye nezindleko zezinto eziphikisayo ngethani lensimbi futhi kwandiswe izinga lokushintsha ukushisa.

I-Ladle lining ingahlukaniswa ibe isendlalelo sokusebenza, isendlalelo esihlala njalo, isendlalelo somugqa we-slag, isendlalelo sokushisa ukushisa nokunye. Ngokwezinto ezibonakalayo zesendlalelo esihlala njalo, kucatshangelwa izici ezimbili zokugcinwa kokushisa kanye nokungena kwensimbi encibilikisiwe, ama-castable aphezulu e-aluminium akhethiwe. Ukuze kuthuthukiswe ukusebenza kwayo kwe-thermal insulation, ungqimba lwesitini se-mullite esilula sakhiwe phakathi kwe-alumina ephezulu ecastable kanye negobolondo lensimbi.

Ungqimba olusebenzayo lwephansi le-ladle luthwala umthelela wensimbi encibilikisiwe kanye nokucindezela okukhulu okumile, ngakho-ke i-corundum castable iyakhethwa. Izitini ze-magnesia-carbon zakhiwe eduze kwezitini zokungenisa umoya kanye nezitini ze-nozzle block, ezingenza kube lula ukuhlakazeka nokulungisa futhi kuvimbele ukwanda ngokweqile. Ungqimba olusebenzayo lodonga olugqokelwe luthintwa ukumuncwa kwekhabhoni yensimbi encibilikisiwe, ukuguguleka okuwa nokuguguleka kwe-slag ngesikhathi sokucwengwa. Le ngxenye kufanele ibe nokuvikeleka okuhle kokuguguleka, ukumelana nokuguguleka, nokumelana ne-oxidation. I-Corundum castable isetshenziswa. Ukwakhiwa kwezitini ze-magnesia-carbon emgqeni we-slag kudinga amandla aqinile e-anti-oxidation kanye ne-anti-rosion.
