Ubushinwa 27SiMn uruganda rukora ibyuma bya hydraulic
27SiMn umuyoboro wicyuma udafite ikidodo, ni ukuvuga 27 silicon manganese umuyoboro wicyuma udafite kashe, nikimwe mubikoresho byumuyoboro wicyuma udafite kashe, kandi karubone iri hagati ya 0.24-0.32%. SIMN itondekanye ukundi kuko ibiri muri silicon manganese mubintu bitanu (karubone C, silicon Si, manganese Mn, fosifore P, sulfure s) ni 1.10-1.40%. 27SiMn idafite umuyoboro ikwiranye ninganda zamashanyarazi, uruganda ruteka, inganda zikora imiti, ibinyabiziga nibikoresho byubwato, nibindi.
27SiMn, umuyoboro wa hydraulic. Kode ihuriweho na digitale: a10272
Bisanzwe: GB / t17396-2018
Ubu bwoko bwibyuma bufite imiterere irenze 30Mn2 ibyuma, gukomera cyane, gukomera kwa diameter ya 8 ~ 22mm mumazi, imashini nziza, plastike yo hagati yubukonje bukabije no gusudira; Byongeye kandi, ubukana bwibyuma ntibugabanuka cyane mugihe cyo kuvura ubushyuhe, ariko bufite imbaraga nyinshi kandi zirwanya imbaraga, cyane cyane iyo kuzimya amazi; Nyamara, iki cyuma cyumva neza cyera, ubushyuhe bukabije hamwe nubushyuhe bukabije mugihe cyo kuvura ubushyuhe.
Ubu bwoko bwibyuma bikoreshwa cyane cyane mu kuzimya no kurakara kugira ngo bikore ibice bishyushye bisaba gukomera no kwambara birwanya; Irashobora kandi gukoreshwa mugihe gisanzwe cyangwa gishyushye kizunguruka, nka traktor track pin, nibindi.
Gukoresha 27 SIMN umuyoboro udafite umuyoboro hamwe nicyuma gisanzwe

Ibikoresho bya mashini ya 27SiMn umuyoboro wicyuma udafite kashe
Imbaraga zingana σ b (MPa): ≥980
gutanga umusaruro σ s (MPa): 35835
Kurambura δ 5 / (%): ≥12
Kugabanya agace ψ / (%): ≥40
Ingufu zo gukuramo ingaruka (agaciro k'ingaruka) (aku2 / J): ≥ 39
Imiyoboro yose idafite ibyuma igomba kugeragezwa kumiterere yubukanishi. Uburyo bwo gupima imiterere yubukanishi bugabanijwemo ibyiciro bibiri: ikizamini cya tensile hamwe nikizamini gikomeye.
Ikizamini cya Tensile nugukora umuyoboro wicyuma udafite ingero mucyitegererezo, gukurura icyitegererezo kugirango ucike kumashini igerageza, hanyuma upime kimwe cyangwa byinshi mubukanishi. Mubisanzwe, imbaraga zingana gusa, imbaraga zitanga umusaruro, kuramba nyuma yo kuvunika no kugabanya agace birapimwa.
Ikizamini cyo gukomera nugukanda buhoro buhoro indenter mucyitegererezo ukurikije ibihe byagenwe, hanyuma ukagerageza uburebure bwimbitse cyangwa ubunini, kugirango umenye ubukana bwibintu.
Imashini nziza, plastike ikonje ikonje kandi isudira; Byongeye kandi, ubukana bwibyuma ntibugabanuka cyane mugihe cyo kuvura ubushyuhe, ariko bufite imbaraga nyinshi kandi zirwanya imbaraga, cyane cyane iyo kuzimya amazi; Nyamara, iki cyuma cyumva neza cyera, ubushyuhe bukabije hamwe nubushyuhe bukabije mugihe cyo kuvura ubushyuhe.
Icyitonderwa cyo gukuza cyane kugenzura imiyoboro idafite ibyuma
Icyitonderwa cyo kugenzura gukomeye kwicyuma kitagira icyuma kirimo ingingo zikurikira:
1. Ubujyakuzimu nubunini bwubuso bwa decarburisation.
2. Uburebure n'ubujyakuzimu bw'udusembwa twinshi hejuru, kugabanuka k'umwobo, gutandukanya hagati ya karubone na sulfuru.
3. Ikwirakwizwa rya ferrite na pearlite mu miyoboro y'icyuma idafite kashe.
4. Izindi microstructure zifite inenge, hamwe nubunini bwingano, uburinganire bwimiyoboro idafite uburinganire hamwe nibirimo.
