Lapho isithando somlilo esishisayo sisebenza, ibhodi le-ceramic elifaka uhlaka lwendwangu yesithando somlilo lithintwa ukushintsha okubukhali kwezinga lokushisa phakathi nenqubo yokushintshanisa ukushisa, ukuguguleka kwamakhemikhali othuli okulethwa igesi yesithando somlilo, umthwalo wemishini, nokuguguleka kwegesi evuthayo. Izizathu eziyinhloko zokulimala kwe-hot blast furnace lining yilezi:
(1) Ukucindezeleka okushisayo. Lapho ushisa isithando somlilo esishisayo, izinga lokushisa lekamelo elivuthayo liphezulu kakhulu, futhi izinga lokushisa elingaphezulu kwesithando somlilo lingafinyelela ku-1500-1560 ℃. Izinga lokushisa liyancipha kancane kancane ukusuka phezulu kwesithando somlilo eduze kodonga lwesithando somlilo kanye nezitini zokuhlola; Ngesikhathi sokunikezwa komoya, umoya obandayo wesivinini esikhulu ushaywa usuka phansi kwe-regenerator futhi ushise kancane kancane. Njengoba isitofu se-hot blast sihlala sifudumeza futhi sinikeza umoya, ulwelwesi lwesitofu sokuqhuma okushisayo kanye nezitini zokuhlola kuvame ukupholisa ngokushesha futhi kufudumale, okwenza i-masonry iqhekeke futhi icwecwe.
(2) Ukugqwala kwamakhemikhali. Igesi yamalahle nomoya osekela ukuvutha kuqukethe inani elithile lama-alkaline oxides. Umlotha ngemva kokuvutha uqukethe u-20% we-iron oxide, u-20% we-zinc oxide kanye no-10% we-alkaline oxides. Eziningi zalezi zinto zikhishwa esithandweni, kodwa ezimbalwa zazo zinamathela ebusweni bomzimba wesithando somlilo futhi zingene esitini somlilo. Ngokuhamba kwesikhathi, ipuleti le-ceramic yokufakwa kwesithando somlilo nezinye izakhiwo zizolimala, ziwe, futhi amandla azoncipha.
Ushicilelo olulandelayo sizoqhubeka nokwethula izizathu zokulimala kweibhodi le-ceramic insulationwe-hot blast furnace lining. Sicela uhlale ubukele!
