Iindlela zokunciphisa iindleko zokubola kwe-refractory lining kwisithando somlilo

Ngomlinganiselo omkhulu wovavanyo lokumelana ne-slag kunye nokusebenza okwenyani komguquli, ulwazi oluthile lokuxhathisa ukubola kwe-refractory linings inokufumaneka:

(1) Ukubunjwa kwesinyithi esinyibilikisiweyo kunempembelelo ebalulekileyo kubomi be-refractory lining, umxholo we-silicon, ihlathi kunye nesulfure.

(2) Ukushisa okuphezulu kakhulu kwesiphelo somguquli kuya kukhokelela ekunciphiseni ubomi bomgca wesithando somlilo. Xa iqondo lokushisa lokugqibela lingaphezulu kwe-1700 ° C, yonke i-10 ° C inyuka iya kwandisa kakhulu izinga lokubola kwe-refractory lining of the furnace.

(3) Ukwandisa i-alkalinity ye-slag kunenzuzo ekunciphiseni ukubola kwe-slag kwi-refractory eyisiseko.

(4) Ukwandisa umxholo we-Mg0 kwi-slag kunokunciphisa ukubola kwe-slag kwi-refractory lining yesithando somlilo.

(5) Ukwandisa umxholo we-Fe0 kwi-slag kuya kubangela ukubola kwezinto ezichasayo ze-furnace lining.

(6) Kwinqanaba lokuqala lokuguqulwa kokuguqulwa, isiseko se-slag sincinci, kwaye i-lining iyancipha kakhulu. I-Dolomite slag kufuneka isetyenziswe ukwenza umxholo we-Mg0 kwi-slag kufuphi ne-state saturated.

(8) Phakathi kwe-dolomite kunye ne-magnesia i-dolomite refractories, i-Mg0 inokumelana nokukhukuliseka okungcono kwe-slag kune-Ca0, kodwa ubukho be-Ca0 bunokuphucula ubushushu obuphezulu be-thermoplasticity kunye ne-slag yokungena kwe-refractories.

(9) Impahla ekrwada yerefractories yelaning yesithando somlilo kufuneka ibe nobunyulu obuphezulu. Ngokomzekelo, isanti ye-magnesium ye-dolomite idinga ukungcola okupheleleyo kwe-SiO2 + A12O3 + FeO ngaphantsi kwe-3%; ezinye ezifana ne-magnesia edityanisiweyo, igraphite, njl njl. nazo zineemfuno ezifanayo.
