Amakuru adafite ibyuma amakuru yamakuru

27simnibyuma bitagira icyuma, ni27SiMn ibyuma bitagira ibyuma, ni kimwe mu bikoresho bya tebes idafite ibyuma.Ibirimo bya karubone biri hagati ya 0.24 na 0.32%.Imirongo imwe ya simn ni ukubera ibintu bitanu (karubone C, silicon Si na manganese).Muri Mn, fosifore P, na sulfure S, ibirimo silicomanganese ni 1.10 kugeza 1.40%.27simn idafite umuyoboro ikwiranye ninganda zamashanyarazi, uruganda ruteka, inganda zikora imiti, imodoka, ibikoresho byubwato.
27simn idafite ibyuma byerekana uburemere uburemere bwa formula itagira icyuma kuri metero uburemere W = 0.02466 * S (DS)
Ikimenyetso Ibisobanuro: D = Diameter yo hanze S = Kubara uburebure bwurukuta urugero: Kubijyanye numuyoboro wicyuma udafite umurambararo ufite diameter yo hanze ya 60mm nuburebure bwurukuta rwa 4mm, ubara uburemere kuri m.
Uburemere kuri m = 0.02466 * 4 * (60-4) = 5.52Kg

Igiciro cyicyuma kitagira icyuma kiri hejuru ya 500-800 yuan / toni hejuru yicyuma cyogosha cyogosha, kandi igiciro cyicyuma kidafite icyuma kirenga 800-1200 yuan / toni ugereranije nicyuma kitagira ibyuma. | Umuyoboro w'icyuma udafite uburinganire ugerwaho cyane cyane mukugabanya impagarara, kandi inzira yo kugabanya impagarara ni inzira ikomeza kuzunguruka aho icyuma fatizo kidafite icyuma.Hashingiwe ku kwemeza ubwiza bwo gusudira umuyoboro w’umubyeyi, inzira yo kugabanya impagarara z’umuyoboro wasuditswe ni ugushyushya umuyoboro wose wasuditswe kugeza kuri dogere selisiyusi 950 cyangwa zirenga, hanyuma ukagera kuri diametre zitandukanye n’inkuta na kugabanya impagarara (yose hamwe 24 pass yo kugabanya kurambura).Umuyoboro mwinshi wuzuye, umuyoboro ushyushye wibyuma bikozwe niyi nzira hamwe numuyoboro usanzwe wo hejuru wasuditswe uratandukanye cyane.Nyuma yo gushyushya mu itanura rishyushya, imiterere ya metallografiya hamwe nubukanishi bwa weld hamwe nicyuma cyababyeyi birashobora kuba bihuye rwose.Icyiciro cya kabiri kigabanya kugabanuka no kugenzura byikora bituma umuyoboro wuzuye (cyane cyane umuzenguruko wumuyoboro hamwe nuburinganire bwurukuta) neza kuruta umuyoboro usa utagira kashe.Amazi meza hamwe nigituba gikorerwa mubihugu byateye imbere kwisi byafashe umubare munini wagusudira umuyoboro udafite inzira.Hamwe niterambere ryumuryango, imiyoboro yo mu rugo ishyushye izengurutswe buhoro buhoro yasimbuye imiyoboro idafite kashe.
