Ubweya wa Slag ndi mtundu wa ulusi woyera wa thonje wokhala ngati mchere womwe umapangidwa ndi slag monga zopangira zazikulu ndipo umasungunuka mu ng'anjo yosungunuka kuti upeze zinthu zosungunuka.Pambuyo pokonzanso, ndi mchere wonyezimira wa thonje womwe uli ndi mphamvu zotetezera kutentha ndi kutsekemera kwa mawu.Pali njira ziwiri zazikulu zopangira ubweya wa slag: njira ya jakisoni ndi njira ya centrifugal.Zopangira zimasungunuka ndikutuluka mu ng'anjo, ndipo njira yowombera ubweya wa slag ndi nthunzi kapena mpweya woponderezedwa umatchedwa njira ya jekeseni;njira yomwe zopangira zimasungunuka mu ng'anjo zimagwera pa disc yozungulira ndikuponyedwa mu ubweya wa slag ndi mphamvu ya centrifugal imatchedwa njira ya centrifugal.Zopangira zazikulu zopangira ubweya wa slag ndi kuphulika kwa ng'anjo yamoto, yomwe imakhala 80% mpaka 90%, ndipo mafuta ndi coke.

Kugwiritsa ntchito kuphulika kwa ng'anjo slag, ferromanganese ndi ferronickel monga zipangizo za ubweya wa slag zingathe kuchepetsa kwambiri kupanga mphamvu zamagetsi ndi ndalama, kukonza chilengedwe, komanso kukhala ndi ubwino wabwino pazachuma.Ziwerengero zikuwonetsa kuti pa tani imodzi iliyonse yazinthu zotchinjiriza zaubweya zomwe zimagwiritsidwa ntchito mnyumba, tani imodzi yamafuta imatha kupulumutsidwa pachaka.Mtengo wopulumutsa malasha pagawo lililonse ndi 11.91kg-standard malasha/m2 pachaka.Ndikukula kosalekeza kwa kusunga mphamvu ndi kuchepetsa utsi m'dziko langa, zinthu zopangidwa ndi ubweya wa mchere ndi ntchito zawo zikukumana ndi mwayi waukulu wachitukuko.M’zaka 20 zapitazi, mphamvu zamagetsi zakhala zikuchulukirachulukira.Kumanga chitetezo champhamvu, kuteteza moto, kutsekereza mawu komanso kuchepetsa phokoso zakhala cholinga chachikulu.Zopangira ubweya wa mchere zimagwiritsidwa ntchito kwambiri ngati zida zomangira zatsopano pantchito yomanga.Ubweya wa Slag ndi ubweya waufupi wamchere wopangidwa kuchokera ku slag, womwe umagwiritsidwa ntchito kwambiri ngati zida zotchingira kutentha komanso zida zoyamwitsa mawu.
