Izinto eziphikisayo ze-cupola

I-cupola yisithando somlilo sokwenza insimbi noma isithando somlilo esinyakazayo, futhi umsebenzi wayo oyinhloko uwukwenza insimbi. Izinga lokushisa elisebenzayo lingu-1400 ~ 1600 ℃. Umzimba wesithando somlilo uhlukaniswe ngezansi kwesithando somlilo, umzimba wesithando somlilo, i-forehearth kanye nebhuloho.

Iphansi le-cupola lithintana ngqo nensimbi encibilikisiwe eshisayo futhi lithwala isisindo sayo yonke inkokhiso. I-ASC ramming material noma i-carbon ramming material kufanele isetshenziswe kule ngxenye ukusiza ukuthuthukisa impilo ye-cupola bottom.

Ungqimba olungaphezulu lokusebenza lomzimba wesithando somlilo luthinteka ngomshini futhi lugqokwe ngesikhathi sokushaja. Yakhiwe ngezitini zensimbi eziyizimbotshana ezimise okwefeni, kanti uhlangothi olungaphandle lwenziwe ngesihlabathi se-quartz.

Ungqimba olusebenzayo lwengxenye engezansi yomzimba wesithando somlilo, indawo evuthayo ye-coke ku-tuyere nangaphezulu ziphezulu kakhulu ekushiseni, futhi zingaphansi kokuguguleka kwe-slag, ukuguguleka kokugeleza komoya kanye nokuhuzuka. Lapha, kusetshenziswa izitini ze-chrome ze-magnesia ezingagqwali noma izitini ze-magnesia.

Isimo se-oxidizing sengqimba ephansi yokusebenza komzimba wesithando sibuthakathaka, futhi kusetshenziswa impahla ye-ASC ramming. Ezinye izingxenye zomzimba wesithando somlilo ziphansi izinga lokushisa, ngakho-ke kusetshenziswa izitini zobumba noma izitini ze-semi-silica. Ungqimba oluhlala njalo noma ungqimba lokufakwa kweziko lomzimba wesithando somlilo lwenziwe ngezitini zobumba ezilula ezinesisindo sobumba.

Sebenzisa izitini zobumba noma izitini eziphezulu ze-alumina endaweni yangaphambili kanye nezingxenye zebhuloho ze-cupola, futhi usebenzise i-ASC ramming material engxenyeni ethintana nensimbi encibilikisiwe; sebenzisa i-ASC ramming material enokuqukethwe okuphezulu kwe-silicon carbide, izingxenye ezakhelwe ngaphambili noma izitini eziphikisayo zengxenye ethinta i-slag; Sebenzisa izitini zobumba noma izitini zobumba ezingasindi ukuze uvale noma izingqimba ezihlala njalo.

Ngokuvamile, phansi kwesithando somlilo kusebenzisa izinto ze-carbon ramming, izitini zobumba, kanye ne-ASC ramming materials, maphakathi nomzimba wesithando somlilo zisebenzisa izitini ze-magnesia chrome, izitini ze-magnesia, izitini ze-corundum, nezitini zobumba, phezulu kwesithando somlilo sisebenzisa i-hollow. izitini zensimbi, kanye nengxenye engezansi yomzimba wesithando somlilo izitini zobumba, izitini ze-ASC, izinto ze-ASC ramming, ama-ASC preforms, ama-ASC preforms okukhipha i-slag, izinto ze-ASC ramming, kanye nodaka lwesibhamu sekhwalithi ye-ASC kanye ne-ASC preforms yokuphuma kwensimbi.

Izitini zobumba zokubikezela, amabhuloho, izingqimba ezihlala njalo, izitini ze-ASC, izitini zobumba ezivikelayo ezinesisindo esincane sezingqimba ezihlala njalo noma izingqimba zokufakelwa.
