Kugadzirisa kuronga kwezvidhinha zvinoramba uye zvinokandwa zveNoranda vira

Noranda furnace lining inoshandisa alkaline refractory zvidhinha, yakanyatsobatanidzwa ne magnesia-chrome zvidhinha, izvo zvine kunaka kwepamusoro-tembiricha vhoriyamu kugadzikana, kuderera kunooneka porosity, kuderera kwemhepo permeability, kunaka kwekushisa kwekushisa kwekudzivirira uye slag erosion resistance; electrofusion yakasanganiswa ne magnesium Chrome zvidhinha zvine kuchena kwemakemikari akakwira, kuderera kwehutsvina, kuwanda kwehuwandu, kusimba kwekushisa kwepamusoro, kusimba kwekunyungudika kwe slag uye kupisa kwakanyanya kwe flue gasi; nepo fused cast magnesia chrome zvidhinha zvinodhura, asi zvinoshingirira kutonhora kwepamusoro uye kunyungudika Corrosion uye kusakura kwevhu zvinonyanya kunaka. Iwo anowanzo shandiswa mukiyi uye nyore kunyungudika zvikamu zvemuviri wechoto. Tafura 1 inoratidza zvinonyanya zviratidzo zvemagnesia-chrome zvidhinha zveNoranda furnaces.

Sezvo choto cheNoranda cheimwe kambani chakavakwa chikaiswa mukugadzirwa, zvikamu zvakakanganisika zvemucheka wega wega wekunyungudutsa kugadzirwa zvakaongororwa, kuongororwa nekutsvagirwa. Mumakore apfuura ekugadzirisa, iyo yakagadziridzwa dhizaini yezve refractory zvinhu zvechikamu chimwe nechimwe cheiyo lining yakatemwa zvakare. Munzvimbo yakaoma uye isina njodzi, chiteshi chekuchaja pahafu yemadziro ekuchaja, gomba rinopisa rakagadzirwa ne magnesia chrome zvidhinha, slag discharge end wall, slag line lineing pamativi ese egomba rekupisa uye kunaya kwemvura. nzvimbo yakasarudzwa UB605-13R1; mhangura matte Fused cast magnesia chrome zvidhinha zvichiri kushandiswa pakubuditsa uye yemhangura port launder. Zvimwe zvikamu zvakadai sechoto pasi uye denga revira zvose zvinosarudzwa zvakananga zvakasanganiswa ne magnesia-chromium yekufambisa furnace pasi yakakwirira-alumina zvidhinha uye zvisina kuumbwa zvidhinha zvigadziriswe, kuitira kuti nzvimbo yezvigadzirwa zvinoramba zvisimudzirwe zvishoma nezvishoma uye zvishoma nezvishoma.

Pakati pavo, choto cheNora Randa chichangobva kuvakwa chakaiswa mukugadzirwa kwemazuva 316, kuisa rekodhi pasi rose munguva yekugadzirwa kwemhando imwechete yevira. Mushure mekugadzirisa, iyo refractory material yakashandiswa kugadzirisa kugadzirisa, uye kuenderera mberi kwekugadzirwa kwaiva mazuva 494, iri pedyo nerekodhi yenyika yemazuva 498 yehupenyu hwevira rimwe chete.
