Umbhobho wentsimbi ongenamthungo otsalwa ngokubandayiumbhobho wentsimbi ongenamthungo otsalwa ngokubanda ochanekileyongokuchaneka okuphezulu komgangatho kunye nokugqiba kakuhle komphezulu wokwakhiwa komatshini kunye nezixhobo zehydraulic.Ukukhetha umbhobho wentsimbi ochanekileyo ongenamthungoukwenza ubume boomatshini okanye izixhobo zehydraulic kunokonga kakhulu ixesha lomatshini, ukuphucula izinga lokusetyenziswa kwezinto kunye nokuphucula umgangatho wemveliso.
Ukuze ufumane imibhobho yentsimbi engenamthungo kunye nobukhulu obuncinci kunye nomgangatho ongcono, ukuqengqeleka okubandayo, umzobo obandayo okanye zombini iindlela kufuneka zamkelwe.I-Cold rolling idla ngokuqhutyelwa kwi-mill-high-high, kunye nemibhobho yensimbi engenamthungo ifakwe kwi-annular pass eyenziwe yi-variable cross-section circular groove kunye neplagi edibeneyo ye-conical.Umzobo obandayo udla ngokuqhutywa kwi-0.5 ~ 100T ikhonkco elilodwa okanye umatshini wokuzoba obandayo ophindwe kabini.
2. Umbhobho wensimbi ongenamthungo owenziwe ngokubanda uyimveliso evele kwiminyaka yamuva nje, ngokukodwa ngenxa yokuba umngxuma wangaphakathi kunye nemilinganiselo yodonga lwangaphandle inokunyamezela okungqongqo kunye noburhabaxa.
Iimpawu zeumbhobho wentsimbi ongenamthungo (uqengqiwe) obandayo:
1. Idayimitha yangaphandle encinci.2. Ukuchaneka okuphezulu kungasetyenziselwa ukuveliswa kwebhetshi encinci 3. Ukuchaneka okuphezulu kwemveliso ebandayo (eqengqiwe) kunye nomgangatho omhle womphezulu.4. Ummandla womnqamlezo wombhobho wensimbi ongenamthungo unzima ngakumbi.5. Ukusebenza kombhobho wensimbi ongenamthungo uphezulu, kwaye isinyithi sinobunzima.Imibhobho yentsimbi engenamthungo yezakhiwo(GB/T8162-2008) yimibhobho yentsimbi engenamthungo yezakhiwo ngokubanzi kunye nezakhiwo zoomatshini.Luhlobo lombhobho wensimbi ongenamthungo ohlelwe ngokweendlela ezahlukeneyo zokusetyenziswa.Ububanzi bokusetyenziswa bubandakanya zonke iintlobo zemibhobho yentsimbi yesakhiwo engenamthungo esetyenziswa kwizakhiwo eziqhelekileyo kunye nezakhiwo zemishini, kunye nenani elikhulu lamashishini afana nokwakhiwa, oomatshini, ukuthutha, ukuhamba ngeenqwelomoya, ukusetyenziswa kweoli, njl.
Umahluko ophambili phakathi kwe-annealing kunye nokuqhelekileyo:
1. Umlinganiselo wokupholisa we-normalization ukhawuleza kancinci kunoko-annealing, kwaye iqondo le-supercooling liphezulu 2. I-microstructure efunyenwe emva kokuqhelekileyo ilungile, kwaye amandla kunye nobunzima buphezulu kune-annealing.
Ukukhethwa kwe-annealing kunye nokuqhelekileyo:
1. I-normalizing idla ngokusetyenziswa endaweni ye-annealing kwi-low-carbon seamless steel pipes kunye nomxholo wekhabhoni ongaphantsi kwe-0.25%.ngokuba
Ukukhawuleza ukupholisa izinga lokupholisa, kunokuthintela umbhobho wensimbi ongenamthungo ophantsi wekhabhoni ukuba ungahluli kunye nomda weenkozo kunye nokufuduka kumaxesha amathathu e-carburization Ukuphucula ukusebenza kwe-deformation ebandayo yeendawo ze-stamping;Ukulungelelanisa kunokuphucula ubulukhuni bentsimbi
Ukunyanzeliswa kombhobho we-carbon seamless steel;Xa ingekho enye inkqubo yonyango lobushushu, i-normalizing can Ukucokisa ingqolowa kunye nokuphucula amandla ombhobho wentsimbi ephantsi-carbon ingenamthungo.
2.Umbhobho wentsimbi ongenamthungo otsalwa yikhabhoni ebandayokunye nomxholo wekhabhoni phakathi kwe-0.25 kunye ne-0.5% nayo inokutshintshwa ngokuqhelekileyo
Buyisela indawo ye-annealing, nangona ukuqina kombhobho wentsimbi epholileyo otsalwa ngokubanda wentsimbi ephakathi kwekhabhoni kufutshane nomda ongentla womxholo wekhabhoni uphezulu kancinane emva kokuqhelekileyo Uphakamileyo, kodwa unokunqunyulwa, kwaye ixabiso lesiqhelo liphantsi kwaye imveliso iphezulu. .3.Umbhobho wensimbi ongenamthungo obandayo kunye nomxholo wekhabhoni phakathi kwe-0.5 kunye ne-0.75% unomxholo ophezulu wekhabhoni,
Ubunzima emva kokuqhelekileyo buphezulu kakhulu kunobo bokucoca, ngoko ke kunzima ukwenza ukusika, ngoko ngokubanzi Sebenzisa i-annealing epheleleyo ukunciphisa ubulukhuni kunye nokuphucula ukucutshungulwa.
4. Ikhabhoni ephezulu okanye isixhobo sentsimbi esinekhabhoni ＞ 0.75% yombhobho wentsimbi ongenamthungo otsalwa ngokubanda ngokuqhelekileyo wamkela ibhola I-Chemical annealing isetyenziswa njengonyango lokuqala lobushushu.Ukuba kukho inethiwekhi ye-cementite yesibini, kufuneka iqhutywe kuqala ukupheliswa koMlilo.I-Anealing kukufudumeza umbhobho wentsimbi ongenamthungo otsalwa ngokubanda kubushushu obufanelekileyo kwaye uwugcine kangangexesha elithile, Inkqubo yonyango lobushushu kunye nokupholisa okucothayo.Ukupholisa okucothayo lolona phawu luphambili lokufunxa, kwaye umzobo wokufunxa kunye nokubanda awukho Ngokuqhelekileyo, umbhobho wentsimbi yomthungo upholiswe ukuya ngaphantsi kwama-550 ℃ eziko.I-Anealing isetyenziswa ngokubanzi Unyango olushushu olubanzi luhlala lusetyenziswa njengolungiselelo kwinkqubo yokwenziwa kwezixhobo okanye iinxalenye zomatshini Unyango lobushushu lucwangciswa emva kokuphosa, ukubunjwa kunye ne-welding nangaphambi kokusika (ngokurhabaxa) ukuphelisa inkqubo yangaphambili.Ezinye iziphene ezibangelwa yinkqubo. , kwaye ulungiselele inkqubo elandelayo.
Injongo yokudibanisa: ① ukunciphisa ukuqina kombhobho wentsimbi ongenamthungo otsalwa ngokubanda ukuze kube lula ukwenza oomatshini;② Ukuphelisa iintlobo ezahlukeneyo Uxinzelelo lokuthintela ukuguqulwa kombhobho wentsimbi ongenamthungo otsalwa ngokubanda;③ Cokisa iinkozo ezirhabaxa kwaye uphucule ubume bangaphakathi Lungiselela unyango lokugqibela lobushushu.
