10-50mm Kalisiyumu Silicon Alloy Lump

Gusaba:

Kuberako calcium nicyuma cyamazi muri ogisijeni, sulfure, hydrogène, azote na karubone bifitanye isano ikomeye, bityo calcium ya calcium ya silicon ikoreshwa cyane cyane mukwangiza ibyuma byangiza, gutesha agaciro na sulferi ihamye.Ingaruka ya exothermic ya si - ca wongeyeho ibyuma bishongeshejwe birakomeye.Kalisiyumu ihinduka imyuka ya calcium mubyuma byamazi, bigira ingaruka zikomeye kubyuma byamazi kandi bigira umumaro wo kureremba bitarimo ubutare.Nyuma ya deoxidation, ibyongeweho bitari ibyuma hamwe nibice binini kandi byoroshye kureremba bizakorwa, kandi imiterere nimiterere yibintu bitari ibyuma nabyo bizahinduka.Kubwibyo, si-Ca alloy ikoreshwa mugukora ibyuma bisukuye, ibyuma byujuje ubuziranenge bifite ogisijeni nkeya na sulferi, hamwe nicyuma kidasanzwe kirimo ogisijeni nkeya na sulferi.Ongeramo calcium silicon alloy irashobora gukuraho nka deoxidizer ya nyuma mubyuma bya aluminium muri node ya node, hamwe nicyuma gikomeza |gukora ibyuma bya tundish nozzle gufunga nibindi.Mugihe cyo kuva mu itanura ritunganya ibyuma, ibirimo ogisijeni na sulferi mu byuma bigabanuka kugera ku rwego rwo hasi cyane binyuze mu kwangiza no gusohora ifu ya calcium silikate cyangwa insinga yibanze.Irashobora kandi kugenzura imiterere ya sulfide mu byuma no kunoza imikoreshereze ya calcium.Mu gukora ibyuma bikozwe mu cyuma, si-Ca alloy ntabwo igira uruhare gusa mu kwangiza no kweza, ahubwo inagira uruhare mu gutera inshinge, bigira uruhare mu gukora grafite nziza.Ikwirakwizwa rya grafite mu cyuma cyijimye ni kimwe kandi imyumvire yera iragabanuka.Kandi irashobora kongera silicon, desulfurizasiya, kuzamura ubwiza bwibyuma.
