Isitini se-silica sokunwebeka esingu-Zero

Izinto eziphikisayo ezisetshenziswe emgqeni we-slag we-ladle yokuqala zazihlanganiswe ngokuqondile nezitini ze-magnesia-chrome, ukuncibilika kukagesi bese kuhlanganiswe nezitini ze-magnesia-chrome nezinye izitini ze-alkaline eziphezulu. Ngemuva kokuthi izitini ze-MgO-C zisetshenziswe ngempumelelo kubaguquli, izitini ze-MgO-C nazo zasetshenziswa emgqeni we-slag we-ladle yokucwenga, futhi imiphumela emihle yafinyelelwa. izwe lami kanye neJapane ngokuvamile zisebenzisa izitini ze-MgO-C ezine-resin-bonded ezinokuqukethwe kwekhabhoni engu-12% kuya ku-20%, kuyilapho iYurophu isebenzisa kakhulu izitini ze-asphalt ze-MgO-C, ezinekhabhoni engaba ngu-10%.

I-Kokura Steel Works ye-Sumitomo Metal Corporation e-Japan yasebenzisa izitini ze-MgO-C ezinokuqukethwe kwe-MgO okungu-83% nokuqukethwe kuka-C okungu-14-17% ukuze kuthathelwe indawo izitini ze-magnesia-chrome eziboshwe ngokuqondile kulayini we-slag we-VAD, kanye nempilo yesevisi ye-slag. umugqa unyuswe kusuka ezikhathini ezingama-20 kuye kwezingama-30-32 [9]. I-LF refining ladle ye-Sendai Steel Plant eJapane yasebenzisa izitini ze-MgO-C esikhundleni sezitini ze-magnesia-chrome, futhi impilo yesevisi yomugqa we-slag yanda kusukela izikhathi ezingu-20-25 kuya izikhathi ezingu-40, ithola imiphumela emihle. I-Osaka Ceramics Refractory Co., Ltd. ifunde imiphumela yokuqukethwe kwekhabhoni kanye nohlobo lwe-antioxidant ekuphikisweni kwe-oxidation, ukumelana ne-slag namandla okushisa aphezulu okuguquguquka kwezitini ze-MgO-C. Ucwaningo lubonisa ukuthi izitini ze-MgO-C ezenziwe ngengxube ye-magnesia ehlanganisiwe ne-sintered magnesia, ne-15% ye-phosphorus graphite kanye nenani elincane le-magnesium-aluminium alloy njengama-antioxidants, anomphumela omuhle wokusebenzisa. Uma isetshenziswa ku-100-ton LF ladle slag line, izinga lomonakalo lincishiswa ngo-20-30% uma liqhathaniswa nezitini ze-MgO-C ezinokuqukethwe kwekhabhoni engu-18% futhi ayikho i-antioxidant, futhi izinga lokuguguleka elijwayelekile liyi-1.2-1.3 mm/ isithando somlilo [1].

Njengoba izitini ze-ladle slag ezicwengekile zezwe lami sezamukele izitini ze-MgO-C esikhundleni sezitini ze-magnesia-chrome, umphumela wokusetshenziswa obanzi ube sobala. Ulayini we-slag we-Baosteel Group Corporation we-300t ladle waqala ukusebenzisa izitini ze-MT-14A magnesia-carbon ngoJulayi 1989, futhi impilo yomugqa we-slag isalokhu ingaphezu kwezikhathi eziyi-100; i-150T electric furnace ladle slag line isebenzisa izitini ze-carbon magnesia-carbon ephansi ukuncibilikisa insimbi yentambo, enezinga lokushisa elithephayo elingu-1600℃~1670℃, elithole imiphumela esobala.

Inkampani yethu igxile ekukhiqizeni izitini zekhabhoni ze-magnesia, izitini ze-aluminium-magnesia carbon, izitini ezingezona zekhabhoni zamaladi acolisisiwe, izitini ze-aluminium-silicon carbide carbon zamathangi e-torpedo, nezitini ezintsha ze-carbon-free magnesia kanye nezinhlobonhlobo ze-amorphous refractories, njengokulungisa. kanye nezinto zokudubula zama-converter, izithando zomlilo kagesi namaladi. Siphinde futhi sinikeze ngemikhiqizo eyakhiwe ngokudlidliza, njengezitini zomoya we-ladle, izitini zesihlalo sombhobho ongenisa umoya, izitini zesihlalo se-nozzle kanye nezingxenye ezakhelwe ngaphambili. Sesithuthuke saba yibhizinisi elibanzi eliphikisayo elihlanganisa ucwaningo lwempahla eluhlaza, ukucubungula okujulile kanye nohwebo. Ilabhorethri yethu inesethi ephelele yemishini yokuhlola neyokuhlola. Imishini yethu ingakha izinto ezingavuthiwe, imikhiqizo eqediwe, ihlole futhi ihlole, futhi yakhe imikhiqizo emisha. Sikholelwa ukuthi isayensi nobuchwepheshe yisiqondiso sethu. Ngakho-ke, sithole ubuchwepheshe obuphambili ekhaya naphesheya, sithuthukise ngokuqhubekayo ikhwalithi yomkhiqizo, okuqukethwe kwesayensi nezobuchwepheshe kanye nokuzinza okungokwemvelo, ngaleyo ndlela sithuthukise ubuchwepheshe bokukhiqiza futhi sibuyekeza njalo imishini yethu yokukhiqiza. Sihlinzeka ngohlu olugcwele lwezinsizakalo zobuchwepheshe ngokuya ngosayizi kanye nemingcele yezobuchwepheshe yeziguquli, izithando zomlilo ze-arc kagesi namalebula ngokuya ngezidingo zamakhasimende.
