Thaum tshav kub kub kho Steelpipe
Kev kho cua sov yog hais txog ob txoj kev kho cua sov ntawm quenching thiab kub tempering.Nws lub hom phiaj yog ua kom lub workpiece muaj cov khoom zoo txhua yam.Kub kub tempering yog hais txog tempering ntawm 500-650 ℃.Feem ntau ntawm cov kub qhov chaw ua hauj lwm nyob rau hauv qhov kev txiav txim ntawm kuj loj dynamic load.Lawv dais cov teebmeem ntawm nro, compression, dabtsi yog khoov, torsion los yog shear.Qee qhov chaw kuj muaj kev sib txhuam, uas yuav tsum muaj qee yam hnav tsis kam.Nyob rau hauv luv luv, qhov chaw ua hauj lwm nyob rau hauv ntau yam compound stresses.Cov khoom no feem ntau yog cov txheej txheem ntawm ntau lub tshuab thiab cov tshuab, xws li cov ncej, txuas cov pas nrig, cov pob zeb, lub zog, thiab lwm yam, uas tau siv dav hauv cov cuab yeej siv tshuab, tsheb, tsheb laij teb thiab lwm yam kev lag luam.Tshwj xeeb tshaj yog rau qhov loj hauv kev tsim cov tshuab hnyav, kev kho cua sov yog siv ntau dua.Yog li ntawd, kev kho cua sov ua lub luag haujlwm tseem ceeb hauv kev kho cua sov.Hauv cov khoom siv tshuab, vim muaj qhov sib txawv ntawm kev ntxhov siab, qhov kev ua tau zoo yuav tsum tsis yog tib yam.Feem ntau hais lus, txhua yam ntawm qhov kub kub yuav tsum muaj cov khoom siv kho tshuab zoo heev, uas yog, kev sib xyaw kom zoo ntawm lub zog siab thiab siab tawv kom ntseeg tau tias lub sijhawm ua haujlwm du ntawm qhov chaw.
Kev kho cua sov ntawm cov yeeb nkab steel yog ib qho ntawm cov txheej txheem tseem ceeb hauv kev tsim khoom siv tshuab.Piv nrog rau lwm yam kev siv thev naus laus zis, kev kho cua sov feem ntau tsis hloov cov duab thiab tshuaj lom neeg ntawm tag nrho cov khoom ua haujlwm, tab sis endows lossis txhim kho kev ua haujlwm ntawm lub workpiece los ntawm kev hloov cov microstructure sab hauv lossis tshuaj muaj pes tsawg leeg ntawm workpiece nto.Nws cov yam ntxwv yog los txhim kho qhov zoo ntawm lub workpiece, uas feem ntau tsis pom ntawm qhov muag liab qab.Txhawm rau ua kom cov yeeb nkab steel muaj qhov xav tau cov khoom siv kho tshuab, lub cev thiab tshuaj lom neeg, cov txheej txheem kev kho cua sov feem ntau tsim nyog ntxiv rau kev xaiv cov khoom tsim nyog thiab ntau yam txheej txheem.Hlau yog cov khoom siv dav tshaj plaws hauv kev lag luam mechanical.Lub microstructure ntawm steel yog complex thiab tuaj yeem tswj tau los ntawm kev kho cua sov.Tsis tas li ntawd, cov khoom siv hluav taws xob, lub cev thiab tshuaj lom neeg ntawm txhuas, tooj liab, magnesium, titanium thiab lawv cov alloys kuj tuaj yeem hloov pauv los ntawm kev kho cua sov kom tau txais cov khoom sib txawv.
