Yuav ua li cas cov yeeb nkab steel tsim
Cov yeeb nkab steel yog ib qho tseem ceeb ntawm cov yeeb nkab steel, cov txheej txheem steel yeeb nkab ntau lawm thiab ntau txoj hauv kev ntau lawm, feem ntau hais lus, kev tsim cov yeeb nkab steel tshwj xeeb ua haujlwm thiab cov txheej txheem tshwj xeeb yog dab tsi? Cov hauv qab no yog cov txheej txheem tsim khoom tshwj xeeb thiab cov txheej txheem thev naus laus zis tseem ceeb ntawm cov kav hlau steel rau koj siv:
Cov txheej txheem steel yeeb nkab ntau lawm
① Cov txheej txheem tseem ceeb ntawm kub dov steel yeeb nkab (△ cov txheej txheem tshuaj xyuas tseem ceeb):
Kev npaj thiab tshuaj xyuas lub raj tsis muaj △ cua kub ntawm lub raj tsis muaj → perforation → dov ntawm lub raj → reheating ntawm steel tube → tsau (txo) txoj kab uas hla → Thaum tshav kub kub kho △ Ncaj ntawm cov yeeb nkab tiav → tiav → tshuaj xyuas △ (tsis muaj kev puas tsuaj, lub cev thiab tshuaj lom neeg, rooj tshuaj xyuas) → cia
② Txias dov (kos duab) steel yeeb nkab cov txheej txheem tseem ceeb:
Kev npaj dawb → pickling thiab lubrication → txias dov (kos duab) → Thaum tshav kub kub kho → straightening → tiav → soj ntsuam
Cov txheej txheem ntawm cov yeeb nkab txias steel tuaj yeem muab faib ua ob hom: txias kos duab thiab kub dov. Cov txheej txheem ntau lawm ntawm cov yeeb nkab steel yeeb nkab yog feem ntau nyuaj dua li qhov kub dov. Tube billet yuav tsum xub muab dov los ntawm peb yob, thiab qhov ntsuas qhov ntsuas yuav tsum tau nqa tawm tom qab extrusion. Tom qab ntawd nkag mus rau cov txheej txheem annealing, annealing rau kua qaub kua pickling, pickling yuav tsum tau them sai sai rau seb puas muaj coob tus nto bubbling, yog hais tias muaj ib tug loj tus naj npawb ntawm bubbling qhia tau hais tias qhov zoo ntawm cov yeeb nkab steel tsis tuaj yeem ncav cuag tus qauv sib xws. Cov tsos ntawm cov yeeb nkab steel yeeb nkab yog luv dua li ntawm cov yeeb nkab kub-dov hlau, phab ntsa tuab ntawm cov yeeb nkab steel yeeb nkab feem ntau me dua li cov yeeb nkab kub-dov hlau, tab sis qhov saum npoo zoo li ci dua li cov tuab- phab ntsa steel yeeb nkab, nto tsis dhau ntxhib, thiab txoj kab uas hla tsis dhau burr.
