Ibikoresho byoroshye byuma byuma byuburyo bwiza bwo kugenzura

1, sulfure yibyuma byumwimerere bishyushye

Ibintu bya sulferi ikoreshwa nabi. Ifite imbaraga zikomeye cyane zicyuma gishyushye cya sulfuru na magnesium nyinshi, cerium, calcium, hariho byinshi bihindura byatewe mumashanyarazi, bityo bikagabanya ubushobozi bwo gutera kwangirika kwimiti idatsinzwe. Kubwibyo, mugukora ibyuma byoroshye byuma byuma bigomba kugerageza gukoresha sulforo nkeya irimo fer yingurube na kokiya. Ibisabwa, fata ingamba zambere zo gusiba ni byiza. Ntabwo bivuze ko hamwe na sulfure nyinshi yibyuma bishongeshejwe ntibishobora gutunganywa neza ibyuma byoroshye byoroshye. Inganda nyinshi zo mu gihugu no mu mahanga zifite sulfure zigera kuri 0.06-0.08% by'icyuma gishyushye cya cupola zirashobora kubyara umusaruro ushimishije, ariko kwangirika kwamavuta azakoreshwa muburyo bwinshi. Amakuru ku bunararibonye hamwe na 0.07-0.13% yumuriro wa sulfure wibyuma bishyushye bya grafite ya grafitike ikozwe mucyuma mubihe bimwe na bimwe, nka titanium yo kwagura ibikorwa bivuye mugukoresha ingaruka zirwanya umupira wa sulfuru. Nubwo bimeze bityo ariko, ingano ya sufuru iratunganijwe neza itunganijwe neza.

2, ubushyuhe bwo gutunganya ibyuma bishongeshejwe

Iyo icyuma gishongeshejwe ubushyuhe buke Gao yagize ingaruka zikomeye ku gipimo cyo kwinjiza amavuta, cyane cyane magnesium ishingiye kuri vermicularizing ndetse nibindi byinshi. Ubushyuhe buri hejuru, niko gazi ya magnesium iteka cyane, gutwika bike, bimwe nkibishoboka kuburyo ubushyuhe bwo gutunganya nabwo. Inyandiko isobanura mugihe ukoresheje magnesium titanium composite modifier itunganya ibyuma byoroshye ibyuma, ingaruka zubushyuhe butandukanye bwo kuvura kumiti. Gutunganya kuri 1400 ℃, inyo imeze nka grafite hejuru ya 95%, umupira gake; kuri 1280 ℃ kuvura, hejuru ya kimwe cya kabiri cya grafite nodules. Amavuta avanze ni amwe, ubushyuhe bwo gutunganya igipimo kinini kigaragara cyo kwinjiza.

Mu musaruro nyirizina, ubushyuhe bugomba gutekerezwa kugirango hamenyekane inzira yo guta ubushyuhe busabwa. Nyamara, ubushyuhe bwo gutunganya bugomba kuba butajegajega bushoboka, niba ihindagurika ryubushyuhe ari rinini, amafaranga agomba guhindurwa amavuta, bitabaye ibyo biragoye kwemeza ubuvuzi bwiza.

Ntibisanzwe bishingiye ku isi vermicularizing, ubushyuhe bwo gutunganya buri hejuru Ibyiza, ubushyuhe buri hasi cyane ntabwo byoroshye nubwo, ndetse bwanashonga burundu, bityo bikagira ingaruka kumiti.

3. Ibikorwa byo gutunganya

Kubera ko inzira yikurikiranya yimikorere kubera ihindagurika ryibisubizo byafashwe nkibyoroshye, bityo bisaba ko hakorwa inama yagiriwe neza. Guhuza ibice bigize ibinyomoro, ibinyomoro bitwikiriye urubanza, ingano ninshi nicyuma, ibishishwa bya slag nizindi ngamba, nkibintu bigira ingaruka zitaziguye kumiti.
