Anan, ana iya amfani da tubalin yumbu mai yawa, tubalin alumina masu tsayi, simintin yumbu / fenti, da sauransu.

Sashin jikin tanderun wani bangare ne mai mahimmanci na tanderun fashewar, wanda ake amfani dashi don dumama, ragewa da kuma lalata cajin. A nan, lalacewar kayan aiki da iska mai zafi ya fi tsanani. Zazzabi a tsakiyar jikin tanderun shine 400 ~ 800 ℃, kuma babu lalatawar slag. An fi shafa shi da zaizayar ƙura, girgizar zafi, alkali zinc da ajiyar carbon. Don haka, ana amfani da tubalin yumbu mai yawa da bulo na alumina masu tsayi a cikin ɓangaren sama, kuma ana amfani da bulogin yumbu na phosphate masu hana tsige lalacewa, bulogin alumina masu tsayi, da tubalin sillimanite don ginin ginin; Ƙasan jikin tanderun yana amfani da bulo mai yawa kuma yana sa tubalin yumbu mai jurewa, bulogin alumina masu tsayi, da tubalin corundum. , tubalin Carborundum don masonry.

Ciki na tanderun yana aiki a matsayin mai ɗaukar hoto don haɓakawa, inda aka rage wani ɓangare na cajin da raguwa, kuma rufin tanderun ya lalace sosai ta hanyar ƙarfe. Zazzabi a nan yana da girma kamar 1400 ~ 1600 ℃ a cikin babba kuma 1600 ~ 1650 ℃ a cikin ƙananan sashi. Saboda cikakken tasirin radiation mai zafin jiki, yashwar alkali, iskar gas mai ƙura mai ƙura, da dai sauransu, abubuwan da ke jujjuyawa na rufin tanderun a nan sun lalace sosai. Sabili da haka, ya kamata a zaɓi kayan haɓakawa tare da juriya mai ƙarfi ga yashwar slag da yashwa da abrasion a nan. Ciki na tanderun na iya amfani da tubalin yumbu maras ƙarfi, bulogin alumina masu girma, tubalin graphite, tubalin carbide silicon, tubalin corundum, da sauransu don masonry.

Wutar murhu ita ce wurin da ake ɗora nauyin narkakken ƙarfe da narkakken tulin. Mafi girman zafin jiki a cikin tuyere yankin ne 1700 ~ 2000 ℃, da kuma yawan zafin jiki na tanderun kasa ne 1450 ~ 1500 ℃. Bugu da ƙari, zafi mai zafi ya shafe shi, rufin murhu kuma yana lalacewa ta hanyar slag da baƙin ƙarfe. Tuyere na murhu na iya amfani da tubalin corundum mullite, tubalin corundum mai launin ruwan kasa, da tubalin sillimanite don ginin gini. Ana amfani da bulogin corundum mullite da tubalin corundum mai launin ruwan kasa don yanayin zafi mai zafi na hulɗar slag-baƙin ƙarfe, kuma ana amfani da bulogin carbon mai yawa da tubalin graphite Semi-graphite don yanayin sanyi. Carbon tubalin, microporous carbon tubalin, m carbon tubalin, sidewall launin ruwan kasa corundum low ciminti prefabricated tubalan, hearth zafi-guga man kananan carbon tubalin, makera kasa ta amfani da graphite Semi-graphite carbon tubalin, microporous carbon tubalin, da dai sauransu ga masonry.

Bugu da kari, ana iya amfani da tubalin yumbu, tubalin carbide na siliki, tubalin graphite, gaurayawar corundum castables, simintin siliki carbide castables, ƙwanƙolin ƙarfe na ƙoshin zafi don gyaran tanderun baƙin ƙarfe. Murfin rami yana amfani da ƙananan siminti da manyan simintin ƙarfe na aluminum da ɓangaren skimmer Yin amfani da ƙananan siminti corundum castable, abin da ke jujjuya bututun bututun ya yi kama da na rami na baƙin ƙarfe, kuma za a iya yin ɗigon slag da ɗan ƙaramin abu.
