Yuav ua li cas ua seamless steel kav

1. Cov txheej txheem tseem ceeb ntawm cov kav dej kub dov seamless steel kav (△ cov txheej txheem tshuaj xyuas tseem ceeb):
Kev npaj thiab tshuaj xyuas cov yeeb nkab tsis muaj △ → Cua sov ntawm cov yeeb nkab tsis muaj → Perforation → Rolling ntawm cov yeeb nkab → Reheating ntawm cov yeeb nkab steel → Sizing (txo) → Thaum tshav kub kub kho △ → straightening ntawm cov yeeb nkab tiav → Finishing → Inspection △ (tsis muaj kev puas tsuaj, lub cev thiab tshuaj lom neeg. , kev tshuaj xyuas lub rooj zaum) → Warehouse
2. Cov txheej txheem tseem ceeb ntawm cov khoom txias txias (kos) seamless steel kav yog:
Kev npaj dawb → Acid tu thiab lubrication → Txias dov (kos duab) → Kev kho cua sov → Ncaj → Tiav → Tshuaj xyuas
Cov txheej txheem ntau lawm ntawm cov kav dej seamless steel tuaj yeem muab faib ua ob hom: kev kos duab txias thiab kub dov. Cov txheej txheem ntau lawm ntawm txias dov seamless steel kav yog feem ntau nyuaj tshaj li kub dov. Cov yeeb nkab dawb paug thawj zaug yuav tsum tau mus rau peb-yob txuas ntxiv dov, thiab tom qab extrusion, nws yuav tsum tau mus kuaj kab. Yog tias tsis muaj cov lus teb tawg rau ntawm qhov chaw, cov yeeb nkab puag ncig yuav tsum tau txiav los ntawm lub tshuab txiav, txiav lub billet nrog qhov ntev ntawm ib meter. Tom qab ntawd nkag mus rau cov txheej txheem annealing, qhov twg acidic kua siv rau pickling. Thaum lub sij hawm pickling, kev saib xyuas yuav tsum tau them rau seb puas muaj qhov loj ntawm blistering ntawm qhov chaw. Yog tias muaj ntau qhov blistering, nws qhia tau hais tias qhov zoo ntawm cov yeeb nkab steel tsis ua raws li cov qauv sib xws. Cov tsos ntawm txias-dov seamless steel kav yog luv dua li ntawm kub dov seamless steel kav. Cov phab ntsa tuab ntawm cov kav dej txias-dov seamless steel feem ntau me dua li ntawm cov kav dej kub-kuav los tiag seamless steel kav, tab sis qhov saum npoo zoo li ci dua li cov phab ntsa tuab seamless steel kav, tsis muaj ntau qhov roughness ntawm qhov chaw thiab tsis muaj burrs ntau dhau ntawm txoj kab uas hla.
