Umbhobho wentsimbi yekhabhoni ephakathi ngomnye wemibhobho yokubilisa esetyenziswa kumbhobho webhoyila weplanti yombane. Uninzi lwale mibhobho isebenza phantsi kobushushu obuphezulu kunye noxinzelelo, ngoko ke, kukho iimfuno ezithile kwiipropathi zomatshini wombhobho wentsimbi yekhabhoni ethambileyo, ukusebenza kwe-welding kunye nokusebenza kombutho, ukongeza kokufunekayo ukuba ube nobushushu begumbi elilungileyo kunye neempawu zoomatshini, ezi ityhubhu. zidinga ukusetyenzwa okubandayo, ke ngoko, iimfuno zale mibhobho kufuneka zibe ne-ductility ephezulu kunye nokuqina. Inkqubo yokulungiswa okubandayo ibalulekile kwinkqubo yokufakela umbhobho webhoyila, kodwa kwinkqubo yokugoba ebandayo, ukuqina komsebenzi kuya kuba ngumongo. I-cold-formed general, kukho iindlela ezimbini, enye ayibandanga ngaphambi kokufudumala ibhongo elibandayo lokutshisa. Ifudumeza ifudumeza kuqala ukubhaka iitotshi, ukufudumeza ubushushu ngokomgangatho ngumqhubi ukuba abambe, kwaye emva kokugoba kokubini okubandayo, kwaye akukho nkqubo yonyango lobushushu. Ngoko ke, ukubaleka processing ebandayo badla ukuzisa utshintsho kwiipropati mechanical kunye notshintsho kwintsebenzo imibutho, nto leyo eyakha umbhobho ukukhanya enokubakho kwinkqubo yenkonzo inshorensi ukuba ibe esinye sezizathu ukusilela. Kuyaziwa, ukugoba okubandayo emva kokuqina kubangela ukomelela kwetyhubhu yentsimbi kunye nokwanda kokuqina, ukuqina kunye nokuqina kwehlile, isizathu sophukile ikristale kwaye kufutshane ne-lattice eyomeleleyo ye-SUI yokutyibilika kwenqwelomoya yobhedu, inyusa ukumelana nokutyibilika ukuze uqhubeke ukutyibilika kunzima ukwenza. Ngaphezu koko, ngokunyuka kweqondo lokuguqulwa, umsebenzi wokuqina kweenwele zegolide zanda.

Ngombhobho we-carbon steel omnene, ukucubungula okubandayo (kubandakanya ukubunjwa okubandayo phambi kokufudumala) kuya kuba nefuthe elikhulu kwintlangano yombhobho wensimbi, kuya kukhokelela ngokuthe ngqo ekungaphumeleli okukhulu kokuphuka. Ngoko ke, umbutho kufuneka ube yi-carbon steel pipe ye-cold-formed countermeasures yokulungisa imibhobho encinci.

Ukuphuhlisa ukufudumala okufanelekileyo

Ngokweentsimbi ezahlukeneyo zokuphendula kunye nobushushu bokuhlaziya kwakhona, ukwenza ubushushu obuchanekileyo be-preheat kunye neenkqubo zokusebenza, kwaye ungafudumezi ngobumfama, ungagqithisi indawo yenguqu ye-Ac], ukufudumala kunokuthintela ukuqhekeka kwekona okanye ukubunjwa kwe-micro. -iintanda. Nangona kunjalo, idatha ibonisa ukuba intsimbi ephantsi-carbon kwi-300. C malunga nokuba kuya kubakho nini "i-blue brittle" endaweni yokuqina kweplastiki kuncipha. Ngokuhambelanayo, ukwenzela ukuba kube lula ngakumbi kwisinyathelo sokuguqulwa, ukushisa kwangaphambili kwi-400 ~ 500. I-C yevumba ifanelekile ngakumbi. Kwangaxeshanye, nikela ingqalelo kwizihlangu, itawuli, kubanda kakhulu ukugoba isantya deformation; ngokukhawuleza okukhulu. Ukuphucula isantya sehlobo-emilo, kokukhona ubushushu bobushushu be "Blue marrow".

Ukufudumeza unyango emva kokugoba komnatha

I-recrystallization annealing, kunye nokupheliswa kweempawu zoomatshini ngenxa yokuqina komsebenzi wokutshintsha ngokweenkcukacha ezahlukeneyo kunye neemeko zokusebenza ze-workpiece kufuneka zenziwe kwi-workpiece emva kokusebenza okubandayo. I-640 isetyenziselwa umbhobho wensimbi we-20 # annealing, ingaba yinto efanelekileyo yokunciphisa uxinzelelo kunye nokubuyiselwa kweempawu zoomatshini. Kodwa kufuneka kuqatshelwe ukuba, kwinkqubo yokupholisa elandelayo, kuyimfuneko ukunciphisa ukupholisa, - njengezinga lokupholisa alikwazi ukuba ngaphezu kwe-6 ukuya ku-8. C / imvula.

Ngokufutshane, umbhobho we-carbon steel omnene kwinkqubo yokugoba ebandayo (kubandakanywa nokufudumala), impembelelo ebalulekileyo ekusebenzeni kwentlangano ibe ngumbhobho wensimbi, umphumo othe ngqo wokungaphumeleli kokuphuka okukhulu. Ukushisa umbhobho wentsimbi yekhabhoni owenziwe ngokubanda kufuneka ube ngokungqongqo ngokuhambelana nenkqubo yokubulawa, emva kokuba i-cold-formed kufuneka igweme unyango lobushushu bomgca we-annealing.
