Uburyo bwo gukora nuburyo bwo gushyushya imbaho zishyushye
Ubuhanga bwibanze:
Ku isoko rya rebar iriho, hrb400e konte kuri byinshi. Uburyo bukomeye bwa microalloy nuburyo nyamukuru bwo kubyara hrb400e kwisi. Microalloy ahanini ni vanadium alloy cyangwa niobium alloy, ikoresha umutungo mwinshi wa buri mwaka. Bitewe namikoro make arimo vanadium na niobium, itangwa ryibi bintu bivangavanze rirakomeye. Kubwibyo, niba ibivangwa muri hrb400e ibyuma bishobora kugabanuka, bizatanga inyungu nini mubukungu no mubuzima.
Mu ikoranabuhanga risanzweho, umurongo wikubye inshuro ebyiri utagabanije kandi uringaniza urusyo rusanzwe rushyira ingufu za vanadium imbaraga zibyara hrb400e, kandi ijanisha ryinshi rya vanadium ni 0.035% kugeza 0.045%.
Ipatanti y'Ubushinwa cn104357741a igaragaza ubwoko bwa hrb400e imbaraga zikomeye zirwanya umutingito hamwe nuburyo bwo kuyibyaza umusaruro. Binyuze muri ubwo buryo, ibicuruzwa byarangiye bikozwe ninganda zigabanya kandi zingana, zishobora kwemeza ko ibyuma birangije kuzunguruka bizunguruka ku bushyuhe buke bwa 730 ~ 760 ℃ kugirango ubone Ibinyampeke byiza, ubu buryo ntibukwiriye kumurongo wo gukora utagabanije gusya. Ipatanti y'Ubushinwa cn110184516a iragaragaza uburyo bwo gutegura insinga ndende φ6mm ~ hrb400e. Hifashishijwe ubushobozi bukomeye bwo kuzunguruka bwibikoresho, ubushyuhe buke butangirira ku bushyuhe bwo gushyuha, kandi umusaruro udafite microalloying uraboneka. Ikibi cyubu buryo nuko Ibisabwa imbaraga nimbaraga za moteri yibikoresho bigoye kandi biciriritse biri hejuru cyane, cyane cyane kumurongo wo kubyara torsion kuzunguruka, bigabanya ubuzima bwikigereranyo bwibikoresho kandi byongera amafaranga yo kubungabunga ibikoresho, nimbaraga zumusaruro winsinga ndende φ6mm ~ hrb400e coil yakozwe nubu buryo irarenze. Ubwinshi budahagije, biragoye kwemeza igipimo cyujuje ibyangombwa.
Ibikoresho byo gushyira mu bikorwa tekinike:
Ubuvumbuzi bwa none bugamije gutanga uburyo bwo kubyara ibyuma bishyushye bishyushye, cyane cyane uburyo bwo gukora ibishishwa bishyushye bishyushye bifata insinga ndende φ8 ~ φ10mm ~ hrb400e, bikuraho amakosa yavuzwe haruguru yubuhanzi bwambere kandi bikagabanya umusaruro ikiguzi.
Gahunda ya tekiniki yubuvumbuzi bwa none:
Uburyo bwo kubyaza umusaruro icyuma gishyushye cyometseho icyuma, ibisobanuro byurugero rwicyuma ni φ8 ~ φ10mm, kandi inzira yikoranabuhanga ikubiyemo gushyushya - fagitire - kuzunguruka - kuzunguruka hagati - gukonjesha - mbere yo kurangiza - gukonjesha - kurangiza - gukonja - kuzunguruka - Imeza ikonjesha ikirere - gukusanya ibiceri - gukonja buhoro; ibice bigize imiti ijanisha ryibyuma ni c = 0,20% ~ 0,25%, si = 0,40% ~ 0,50%, mn = 1.40% ~ 1.60%, p≤0.045%, s ≤0.045%, v = 0.015% ~ 0.020%, ahasigaye ni Fe nibintu bidashobora kwirindwa; intambwe zingenzi zikorwa zirimo: ubushyuhe bwitanura ni 1070 ~ 1130 ℃, ubushyuhe bwambere bwo kuzunguruka ni 970 ~ 1000 and, naho ubushyuhe bwo kurangiza ni 840 ~ 1000 ℃. 880 ℃; gushyira ubushyuhe 845 ~ 875 ℃; ubushyuhe bwa nyuma buzunguruka buri munsi yubushyuhe bwa reustallisation ya zone ya austenite; gukonjesha byihuse nabafana kumeza ikonjesha ikirere, ingano yumwuka ni 100%; Ubushyuhe bw'igifuniko ni 640 ~ 660 ℃, ubushyuhe bw'igifuniko cyo kubika ubushyuhe ni 600 ~ 620 and, naho igihe cyo gutwikira ubushyuhe ni 45 ~ 55s.
Ihame ryivumburwa: mubushyuhe bwa 840-880 ℃, ibinyampeke bya austenite byongerwa no guhinduranya ibintu, ariko ntibisubireho. Nyamara, imirongo yo guhindura ibintu ikorwa mubinyampeke bya austenite, kandi impera yimigozi ya deforme muri rusange iba kumupaka wingano, kandi hariho nudusimba twa deformasiyo mubinyampeke nkimbibi zigaragara kugirango zigabanye ingano za austenite. Mugihe cyo guhinduka kuva austenite kugera kuri ferrite, byombi imbibi ndende za austenite nimbibi zigaragara zimbibi zimbibi zikora nkibibanza bya ferrite, bikavamo gutunganya ferrite nyuma yo guhinduka. Ubushyuhe buke buzunguruka mu ruganda rurangiza bigabanya umutwaro wo kuzunguruka urusyo ruciriritse kandi ruri hagati hamwe ninganda zabanje kurangiza kandi byongera ubuzima bwa serivisi bwibikoresho.
Ingaruka zingirakamaro zivumbuwe nizi zikurikira: mugushyiramo agace gato ka v mugukomeza microalloy, imbaraga zumusaruro ziratera imbere, v na c bikora karbide, bigwa mugihe cyo gukonja nyuma yo kuzunguruka, kandi bikagira uruhare mukuzamura imvura. . Inkoni ishyushye ishyushye yibikoresho byavumbuwe ifite imbaraga zingana na 600-700mpa, imbaraga zumusaruro wa 420-500mpa, impuzandengo yumusaruro ungana na 450mpa, na agt> 10%, itanga intera ihagije. Imbaraga z'umusaruro zirahamye, kandi igipimo cyujuje ibisabwa kiri hejuru ya 99%. Ivumburwa mu buryo bwa tekiniki rikemura ikibazo cyuko uruganda ruzunguruka rugoye gukora ubushyuhe buke, kugabanya ibiciro hashingiwe ku kwemeza ko umusaruro utagabanuka, kandi uzana inyungu nyinshi mu bukungu.
Inzira zirambuye
Ibiri muri iki gihangano cyasobanuwe hepfo aha hamwe nibisobanuro.
Uburyo bwo kubyaza umusaruro itsinda ryinsinga ndende φ8mm ~ φ10mmhrb400e ibishishwa. Igikorwa cyo kuzunguruka ni: ubushyuhe bugenda: 1080 ~ 1120 ℃, kwinjira mbere yo kurangiza kuzunguruka 1030 ~ 1060 ℃, kwinjira mubushyuhe bwo kurangiza: 850 ~ 870 ℃, ubushyuhe bwizunguruka: 850 ~ 870 ℃, ubwinshi bwumwuka wumuyaga 100%, winjira mubifuniko ubushyuhe 640 ~ 660 ℃, 600 ~ 620 ℃ hanze yubushyuhe bwo kubika ubushyuhe, igihe cyo gutwikira ubushyuhe ni 45 ~ 55s, kandi gikonja bisanzwe. Ibigize imiti yibikoresho byinsinga byerekana ibivumbuwe byerekanwa mu mbonerahamwe ya 1, kandi imiterere yubukanishi bwinsinga yibikoresho byavumbuwe byerekanwe kumeza 2.
