1. mangane na sulfuru
Generally speaking, sulfur is a harmful element. But for gray cast iron, a small amount of sulfur plays a very important role in the refinement of graphite core and cocrystal groups. Therefore, the sulfur content in gray cast iron should not be less than 0.06%, and it is best to keep between 0.06% and 0.08%. If the sulfur content is too high (>0 . 18%), ubwoko bwose bwingaruka mbi bizagaragara kandi byangiza ubwiza bwa casting.
Sulfuru nikintu gifite ibikorwa bikomeye bya chimique . mugihe ibirimo bya mangase hamwe na etal na karubone, sulfur
FE irashobora gushonga rwose mu gisubizo cy'icyuma {{0} iyo igorofa rishimangira icyiciro gisigaye, buhoro buhoro igisubizo cya SULFUDE, kandi buhoro buhoro, kandi buhoro buhoro, sulfdide, sulfide igaragara.
Nicy yajugunye icyuma, ubuhinzi bwa sulfuru na Manganese burarenze iyi cyuma, kandi gushiraho MN Byiganjemo reaction yasobanuwe muri ikigereranyo gikurikira .
Mn + Fes Mns + FE
Umwanya wo gushonga Mns ni urugero rwa 1620 . mu Gray, Mans Kwinjizamo Icyuma
Mu Gray yatwaye ibyuma, Man na Fes birashobora kunyeganyega na Sulfuru na Sulfuru muri Sulfide yo mu kirere (MNFE) nabyo, niho kunyerera, aho indangagaciro za X, y, y, y, {y, y, {all hindura kubihe byihariye bya Station SHAKA .
Mu myaka yashize, ubushakashatsi bwisesengura ryibyuma ryerekanye ko hari ibijyanye na miliyoni 43 za MNS na (MNFE) ash 1 {5} . 01% yuburemere bwicyuma.
Iyo sulfuru ibaho muri Fes cyangwa ternary co-Crystal, itunganya nigiciro cyamazi kumurongo wa cocrystal, bityo bikabangamira imisoro ya cocrystal, bityo bikabangamira umunwa wa COCSTAL, bityo bikabangamira umunwa wa Corystal, bityo bikabangamira umunwa wa COCSTAL, bityo bikabangamira umunwa wa COCSTAL, bityo bikabangamira umunwa wa COCSTAL, bityo bikabangamira umunwa wa COCSTAL, bityo bikabangamira umunwa wa Corystal, bityo bikabangamira umunwa wa COCSTAL, bityo bikabangamira umunwa wa Corystal, bityo bikabangamira umunwa wa COCSTAL, bityo bikabangamira umunwa wa COCSTAL, bityo bikabangamira umunwa wa COCSTAL, bityo bikabangamira umunwa wa COCSTAL, bityo bikabangamira umunwa wa Corystal imbibi za coprystal itsinda rizakora imitungo ya mashini yamashanyarazi hasi kandi imbibi nini . iyi niyo ngaruka mbi ya sulfuru .
Niba manganeya ahagije ya manganese yongewe ku ibyuma bibuza kubuza FES Sulfuru muri Gray Shot Icyuma kigomba kuba 0 . 06% .} Ibirimo Urupapuro rufite ibibi, kandi biroroshye kubyara umunwa wera.
Uruhare nyamukuru rwa Manganese mu Gray Cast Icyuma nukubuza sulfur kandi ibuza fesi ya manganeya
