Xa isithando somlilo esitshisayo sisebenza, ibhodi ye-ceramic ye-insulation ye-lining ye-furnace ichaphazeleka ngokutshintsha okubukhali kweqondo lokushisa ngexesha lenkqubo yokutshintshiselana kobushushu, ukukhukuliseka kweekhemikhali zothuli eziziswa yigesi yomlilo, umthwalo womatshini, kunye nokukhukuliseka kwegesi evuthayo. Ezona zizathu ziphambili zomonakalo we-hot blast furnace lining zezi:
(1) Uxinzelelo lobushushu. Xa ufudumeza isithando somlilo esitshisayo, ubushushu begumbi lokutsha buphezulu kakhulu, kwaye ubushushu bomphezulu womlilo unokufikelela kwi-1500-1560 ℃. Ubushushu buyancipha ngokuthe ngcembe ukusuka phezulu kwesithando somlilo kunye nodonga lwesithando somlilo kunye nezitena zokukhangela; Ngexesha lokunikezelwa komoya, umoya obandayo ohamba ngesantya esiphezulu uvuthelwa ngaphakathi ukusuka ezantsi kwe-regenerator kwaye ushushu ngokuthe ngcembe. Njengoko isitofu esitshisayo sihlala sifudumeza kwaye sinikezela ngomoya, umbane wesitofu esitshisayo kunye nezitena zokukhangela zihlala zihamba ngokupholisa ngokukhawuleza kunye nokufudumala, okwenza ukuba i-masonry iqhekeze kunye ne-peel.
(2) Ukonakala kweekhemikhali. Irhasi yamalahle kunye nenkxaso yomoya evuthayo iqulethe inani elithile le-alkaline oxides. Uthuthu emva kokutshiswa luqukethe i-20% ye-iron oxide, i-20% ye-zinc oxide kunye ne-10% ye-alkaline oxides. Uninzi lwezi zinto zikhutshwa ngaphandle kwesithando somlilo, kodwa ezimbalwa zazo zibambelela ebusweni bomzimba wesithando somlilo kwaye zingene kwisitena somlilo. Ngokuhamba kwexesha, i-furnace lining insulation plate ye-ceramic kunye nezinye izakhiwo ziya konakaliswa, ziwe, kwaye amandla aya kuncitshiswa.
Ushicilelo olulandelayo siya kuqhubeka ukwazisa izizathu zomonakalo weibhodi ye-ceramic yokugqumayomlilo ovuthayo ovuthayo. Nceda uhlale ubukele!
