Isahani

Ni ibyuma biringaniye biterwa no gusebanya no gukanda nyuma yo gukonja.
Ni igorofa, urukiramende kandi rushobora kuzukwa cyangwa gutemwa kuva mumirongo yagutse.
Icyuma cya Icyuma kigabanijwe ukurikije ubugari, isahani yoroheje iri munsi ya mm 4 (tran mm), isahani yubudozi ni 4-60 ni 60-115 mm.
Impapuro z'ibyuma zigabanyijemo ishyushye kandi zizunguruka ukurikije kuzunguruka.
Ubugari bw'isahani yoroheje ni 500 ~ 1500 mm; ubugari bw'urupapuro rwinshi ni 600 ~ 3000 mm. Amabati ashyirwa mubwoko bw'icyuma, harimo n'icyuma gisanzwe, ibyuma byinshi, alloy ibyuma, ibyuma birwanya ibyuma, urutoki rwa silicon, impapuro z'icyuma, n'ibindi .; Isahani ya Enamel, amasasu, nibindi ukurikije ubuso, hari urupapuro rwa gakondo, urupapuro rwabigenewe, urupapuro rwashyizwe hamwe, nibindi.
Ububiko buke
(Bizwi kandi nka Alloy Steel Steel, HSLA)
1. Intego
Cyane cyane mugukora ibiraro, amato, ibinyabiziga, boialrs, imiyoboro yigituba kinini, imiyoboro ya peteroli, imiyoboro minini yicyuma, nibindi.
2. Ibisabwa
(1) Imbaraga nyinshi: Muri rusange imbaraga zayo zitanga hejuru 300mpa.
. Kubice bisumbano bisudise, gukomera gukomeye.
(3) Imikorere myiza yo gusudira nubukonje bukora.
(4) ubushyuhe buke-buke.
(5) Kurwanya kwangirika.
3. Ibiranga Byose
.
(2) Ongeraho ibintu bishingiye kuri Manganese.
.
Byongeye kandi, ongeraho umubare muto wumuringa (≤0.4%) na fosifore (hafi 0.1%) birashobora guteza imbere ihohoterwa rishingiye ku ruswa. Ongeraho umubare muto wisi yisi urashobora kwikuramo na de dedas, kweza ibyuma, no kunoza imikorere no gutunganya imikorere.
4. Mubisanzwe Byakoreshejwe Ububiko buke
16Mn ni ubwoko bukoreshwa cyane kandi butanga umusaruro bwinshi-buke-buke-imbaraga-imbaraga mugihugu cyanjye. Imiterere ikoresha leta ni Ferrite nziza-perlite, n'imbaraga zayo bigera kuri 20% hejuru ya karubone ya karubone q235, kandi irwanya ibiryo bisanzwe ni 20% hejuru.
15Mnn nigice cyakoreshejwe cyane mubimera byingufu. Ifite imbaraga nyinshi, nubuhanga bwiza, gukomera no gukomera kwiminyururu hasi, kandi bigakoreshwa cyane mu gukora inzego nini nk'ibice, boirors, n'amato.
Nyuma yuko urwego rwimbaraga zirenga 500mpa, imiterere ya Ferrite na Pearlite iragoye kubahiriza ibisabwa, bityo itezwa imbere ya karubone. Wongeyeho cr, mo, mn, b nibindi bintu nibyiza kubona imiterere ya kabite mubihe byo gukonjesha ikirere, kugirango imbaraga ziri hejuru, kandi ibikorwa byo gusudira nabyo birashimishije muri boile , inzara zo hejuru, nibindi
5. Biranga ubuvuzi
Ubu bwoko bwibyuma muri rusange ikoreshwa muburyo bushyushye kandi bukonje kandi ntibusaba kuvura indwara zidasanzwe. Ibikorwa bya Gukoresha muri rusange ni Ferrite + Sorbite.
Alloy Carburized Icyuma
1. Intego
Irakoreshwa cyane mu gukora ibikoresho byo kohereza mu modoka n'ibikoresho, camshafts, piston pin n'ibindi bice by'imashini kuri moteri zo gutwika imbere. Ibice nkibi birabarwa no guterana amagambo no kwambara mugihe cyakazi, kandi mugihe kimwe bitunganya ibintu byinshi byo guhinduranya, cyane cyane bigira ingaruka imitwaro.
2. Ibisabwa
.
(2) Ikositimu ifite ubugiranire bukabije n'imbaraga zikomeye. Iyo ubukana bwa Core budahagije, biroroshye kumena ibikorwa byingirakamaro cyangwa birenze urugero; Iyo imbaraga zidahagije, urwego rwa Carrugi ruvunika byoroshye kandi ruzacibwa.

4. Icyiciro cya Steel hamwe nicyiciro
20CR Ikomeye ALLY Carburize Icyuma. Ubu bwoko bwibyuma bufite imbaraga nke nimbaraga nke.
20Krmnti igihanganye aluloy carburized steel. Ubu bwoko bwibyuma bufite ubukana buhebuje, kumva neza ibintu byinshi, ugereranije no kwitwara neza, kandi ibintu byiza bya mashini na tekinolojiya.
18C22wa4wa na 20cr2ni4a hardden zigoye alloy carburized steel. Ubu bwoko bwicyuma burimo ibintu byinshi nka CR na Ni, bifite uburemere bukabije, kandi bufite uburemere bwiza nubushyuhe bukomeye.
5. Guvura ubushyuhe n'ibikoresho by'imico
Gahunda yo kuvura ishyushye rya steel muri rusange irazimya nyuma yo kwizirika, hanyuma ikababaza ubushyuhe buke. Nyuma yo kuvura ubushyuhe, imiterere yubuso Carburized Igice cya Alboy Clamedite + yakubayeho kwa Martensite + ingano ntoya ya Austenite, kandi ubukana ni 60hrc ~ 62HRC. Imiterere yibanze ifitanye isano nikibazo cyibyuma nigice cyambukiranya ibice. Iyo byuzuye, ni bike-karubone yakuyeho Pridensite hamwe na 40hrc kugeza 48hrc; Kenshi na kenshi, ni troostite, yateje intangiriro yintambara hamwe nicyuma gito. Umubiri w'abahanga, gukomera ni 25hrc ~ 40hrc. Ubwuzuzanye bwumutima muri rusange burenze 700kj / M2.
ALLY YAKOZE KANDI YATANZWE
1. Intego
ALLY YAKOZE KANDI YAKORESHEJWE CYANE MU GUKORA Ibice bitandukanye byingenzi kumodoka, Ibikoresho, Ibikoresho by'imashini n'izindi mashini, ibiciro, bihuza inkoni, ibiti, nibindi
2. Ibisabwa
Ibice byinshi byazimye kandi bikagira ingaruka kumikorere itandukanye, ibintu byimihangayiko ni ibintu bigoye, kandi birakenewe neza, ni ukuvuga imbaraga nyinshi nuburwayi bwiza nubuka bwiza. ALLY YAKOZE KANDI YATANZWE ITANGAZO NA SNEL NETSENDSENDS. Ariko, imihangayiko yibice bitandukanye biratandukanye, kandi ibisabwa muburemere biratandukanye.
3. Ibiranga Byose
(1) Karuboni Hagati: Ibirimo bya karubone muri rusange hagati ya 0.25% na 0.50%, hamwe na 0.4% muri benshi;
. Kurugero, imikorere ya 40cr ibyuma nyuma yo kwivuza no kwivuza ni hejuru cyane kurenza iyo ya 45 yicyuma;
. Ongeraho Mo na W Ibyuma birashobora kubuza ubwoko bwa kabiri bwumuyaga, kandi ibintu bikwiranye ni hafi 0.15% -0.30% mo cyangwa 0.2% -12%-
Kugereranya imitungo ya 45 yicyuma na 40cr ibyuma nyuma yo guhindagurika no kubaramba
Icyiciro cya Steel hamwe nubuvuzi bwa leta yicyiciro / MM SB / MP SS / M5 /% Y /% AK / KJ / M2
45 Icyuma 850 ℃ Kuzimya Amazi, 550 ℃ gukarangiza F50 700 500 15 45 700
40CR 850 ℃ Kuzimya Amavuta, 570 ℃ Gutemba F50 (Core) 850 650 16 58 1000
4. Icyiciro cya Steel hamwe nicyiciro
.
. Hiyongereyeho Molybdenum ntishobora kunoza uburemere gusa, ariko kandi irinde ubwoko bwa kabiri bwumuyaga.
. Ongeraho Molybdenum ikwiye kuri chromium-nikel ibyuma ntabwo ifite uburemere bwiza gusa, ariko kandi ikuraho ubwoko bwa kabiri bwumuyaga.
5. Guvura ubushyuhe n'ibikoresho by'imico
Ubushyuhe bwa nyuma bwa ALLY buzimye kandi bukagira amabuye yicyuma aragenda kandi ubushyuhe bwo hejuru (buhoronya no burababaje). ALLY YAKOZE KANDI YATANZWE ITANGAZO IRABIKORWA BYINSHI, KANDI KOMIRO BIKORESHEJWE. Iyo bikomeye cyane ari binini cyane, birashobora no kuba umwuka bikonje, bishobora kugabanya inenge zivuza.
Imitungo yanyuma ya aly yazimye kandi ikangisha ibyuma biterwa nubushyuhe bubi. Muri rusange, kubarama kuri 500 ℃ -650 ℃ ikoreshwa. Muguhitamo ubushyuhe bubabaje, imitungo isabwa irashobora kuboneka. Kugirango wirinde ubwoko bwa kabiri bwurukundo rwumukara, gukonjesha byihuse (gukonjesha amazi cyangwa gukonjesha amavuta) nyuma yo gupfukama ari ingirakamaro kunonosora gukomera.
Ibikorwa bya ALLY na Quent no gutereta ibyuma nyuma yo kuvura ubushyuhe busanzwe ni amagambo agaragara ya sorbite. Kubice bisaba ubuso burwanya kwambara (nkibikoresho byambaye imyenda na spindles), kwinjiza hejuru bikurura hejuru no kubara ubushyuhe buke, kandi imiterere yubuso iratera imbere. Ubuso bwo hejuru burashobora kugera kuri 55hrc ~ 58hrc.
The yield strength of alloy quenched and tempered steel after quenching and tempering is about 800MPa, and the impact toughness is 800kJ/m2, and the hardness of the core can reach 22HRC~25HRC. Niba ingano yambukiranya igice ni kinini kandi ntabwo ikomeye, imikorere iragabanuka cyane.
