Inzira yo gutunganya umusaruro
Isahani ya 20g (Ti) ni ubwoko bwibyuma bisabwa cyane kumiterere yubukanishi bwuzuye, ibyuma bisa neza, hamwe nibigize gushonga hamwe na microalloying ibintu byunvikana cyane ningaruka zumutungo utandukanye.Kubwibyo, urufunguzo rwibikorwa bya 20g (Ti) nugutezimbere ibishonga, kugabanya umubare wibyinjijwe mubyuma, hitamo ibintu bikwiranye na microalloying, gukoresha ibizunguruka bigenzurwa, kuzamura ubwiza bwisahani, no gushimangira ikoreshwa rya Ingaruka zo gusaza.Inzira ya tekiniki ya 20g ni: icyuma cyiza cyane cyashongeshejwe treatment uburyo bwo kweza → gushonga muburyo bwiza bwo gutunganya no kweza ibyuma → microalloying no gutunganya ibyuma bishongeshejwe → ibyuma birinda → icyapa cyiza cyane → kugenzura ubushyuhe → imiterere yubushyuhe → kugenzura umubyimba → Kugenzura gukonjesha → ibicuruzwa.
Amasahani ya kontineri akoreshwa mu gukora peteroli, imiti, gutandukanya gaze, kubika gaze no gutwara ibintu cyangwa ibindi bikoresho bisa, nk'iminara itandukanye, guhanahana ubushyuhe, ibigega byo kubikamo, amakamyo, n'ibindi. imbaraga-nyinshi Kubyuma byubatswe, reba GB6654-1996.1 Ibipimo n'uburemere: Ukurikije ibivugwa muri GB709, ubunini busanzwe * ubugari ni 6 ～ 120 * 600 ～ 3800 (mm).
Gushonga no gutunganya
(1) Hindura ibice bigenzura imbere kugirango wongere imipaka yo hasi ya manganese kugeza 0,65%.
.
(3) Igenzura cyane ubushyuhe busuka.
(4) Ibiri muri microalloying element Ti yongerewe kuva 0.003% igera kuri 0.008%.(5) Emera uburyo bwose bwo gusuka kurinda kugirango ugabanye kwinjiza N.
Gutondekanya kubyimbye
Isahani yoroheje <4 mm (yoroheje 0.2 mm), icyuma kibyibushye cya mm 4-60, icyuma kibyibushye cyane mm 60-115 mm.Ubugari bw'isahani yoroheje ni 500-1500 mm;ubugari bw'isahani yuzuye ni 600-3000 mm.Ubwoko bwibyuma byicyuma kibisi Nubusanzwe ni kimwe nicyuma cyoroshye.Kubyerekeranye nibicuruzwa, usibye ibyapa byikiraro, ibyuma byerekana ibyuma, ibyuma bikora amamodoka, ibyuma byumuvuduko wibyuma hamwe nibyuma byinshi byumuvuduko mwinshi wibyuma byibyuma, ibyo bikaba ari plaque yuzuye gusa, ubwoko bumwebumwe bwibyuma nkimodoka Ibyuma by'ibyuma (uburebure bwa mm 2,5-10), icyitegererezo Icyuma (uburebure bwa mm 2,5-8 mm), ibyuma bidafite ingese, ibyuma bitarwanya ubushyuhe, nibindi byambukiranya amasahani yoroheje.2. Isahani yicyuma igabanyijemo ibice bishyushye kandi bikonje ukurikije kuzunguruka.

Itondekanya ukurikije imiterere
1. Isahani yicyuma cyumuvuduko: Koresha inyuguti nkuru R kugirango urangize amanota.Urwego rushobora kugaragazwa numusaruro cyangwa ibirimo karubone cyangwa ibintu bivanga.Nka: Q345R, Q345 niyo ngingo yo gutanga umusaruro.Urundi rugero: 20R, 16MnR, 15MnVR, 15MnVNR, 8MnMoNbR, MnNiMoNbR, 15CrMoR, nibindi byose bigaragazwa nibirimo karubone cyangwa ibintu bivanga.
2. Isahani yicyuma cyo gusudira silindiri ya gaz: Koresha igishoro HP kugirango ugaragaze ko urangije icyiciro, kandi amanota yacyo ashobora kugaragazwa numusaruro, nka: Q295HP, Q345HP;irashobora kandi kugaragazwa nibintu bivangavanze, nka: 16MnREHP.
3. Isahani yicyuma kubiteke: Koresha inyuguti nto g kugirango werekane kumpera yizina ryikirango.Urwego rwarwo rushobora kugaragazwa numusaruro, nka: Q390g;irashobora kandi kugaragazwa nibirimo karubone cyangwa ibintu bivangavanze, nka 20g, 22Mng, 15CrMog, 16Mng, 19Mng, 13MnNiCrMoNbg, 12Cr1MoVg, nibindi.
