Carbon calcining ọkụ silica brik

A na-ejikọta ihe ndị na-emegharị ihe na-eji na slag line nke mbụ ladle na brik magnesia-chrome, ọkụ eletrik wee jikọta ya na brik magnesia-chrome na brik alkaline ndị ọzọ dị elu. Mgbe ejiri brik MgO-C mee ihe nke ọma na ndị na-agbanwe agbanwe, a na-ejikwa brik MgO-C mee ihe n'ahịrị slag nke ladle nnụcha, ma rụpụta ihe dị mma. Obodo m na Japan na-ejikarị brik MgO-C resin nwere ọdịnaya carbon nke 12% ruo 20%, ebe Europe na-ejikarị brik MgO-C nwere asphalt, yana ọdịnaya carbon nke ihe dịka 10%.

Ọrụ Kokura Steel nke Sumitomo Metal Corporation dị na Japan jiri brik MgO-C nwere ọdịnaya MgO nke 83% yana ọdịnaya C nke 14-17% dochie brik magnesia-chrome jikọtara ọnụ na ahịrị VAD slag, yana ndụ ọrụ slag. abawanyela ahịrị site na ugboro 20 ruo ugboro 30-32 [9]. Igwe nchacha LF nke Sendai Steel Plant na Japan jiri brik MgO-C dochie brik magnesia-chrome, na ndụ ọrụ nke eriri slag mụbara site na oge 20-25 ruo ugboro 40, na-enweta nsonaazụ dị mma. Osaka Ceramics Refractory Co., Ltd. mụrụ mmetụta nke ọdịnaya carbon na ụdị antioxidant na nguzogide oxidation, nguzogide slag na ike mgbanwe okpomọkụ nke brik MgO-C. Ọmụmụ ihe ahụ na-egosi na brik MgO-C mere nke ngwakọta nke magnesia fused na sintered magnesia, na 15% phosphorus graphite na obere ego nke magnesium-aluminom alloy dị ka antioxidants, nwere mmetụta dị mma. Mgbe ejiri ya na 100-ton LF ladle slag line, ọnụ ọgụgụ mmebi ahụ na-ebelata site na 20-30% ma e jiri ya tụnyere brik MgO-C nwere ọdịnaya carbon nke 18% na enweghị antioxidant, na nkezi nke mbuze bụ 1.2-1.3 mm/ ọkụ [1].

Ebe ọ bụ na brik ahịrị ladle slag a nụchara anụcha nke obodo m nakweere brik MgO-C kama brik magnesia-chrome, mmetụta ojiji zuru oke apụtawo. Baosteel Group Corporation's 300t ladle slag line malitere iji brik MT-14A magnesia-carbon na Julaị 1989, na ndụ ahịrị slag nọgidere n'elu 100 ugboro; na 150T electric oven ladle slag line na-eji obere carbon magnesia-carbon brik na-agbaze ụdọ ígwè, na a tapping okpomọkụ nke 1600 ℃ ~ 1670 ℃, nke enwetawo doro anya pụta.
