Hauv cov tsos ntawm cov yeeb nkab steel, cov cua sov nthuav dav yog xim liab, thiab lub taub hau sab hauv yog hmoov txhuas yog hmoov txhuas. Ib txoj kev ntawm kev ua hluav taws xob nthuav dav steel yeeb nkab yog ua kom cov me-doo-dhawv yeeb nkab rau hauv cov kab hlau loj loj. Cov khoom siv tshuab ntawm kub-nthuav dav hlau kav yog ib qho me ntsis phem dua li cov ntawm kub-rolled steel kav.
Cov cua sov-nthuav dav hlau yeeb nkab cov yeeb nkab peb feem ntau hais txog cov yeeb nkab steel nrog kuj tsis ntom ntom ntom tab sis muaj zog shrinkage. (Seamless steel yeeb nkab) tuaj yeem raug xa mus rau cov yeeb nkab-nthuav dav cov yeeb nkab kom luv. Ib tug ntxhib raj furing cov txheej txheem nyob rau hauv uas txoj kab uas hla ntawm ib cov yeeb nkab tau nthuav dav los ntawm kab pheeb ces kaum yob txoj kev lossis ib txoj kev kos duab. Thickening steel kav hauv lub sijhawm luv luv ntawm lub sijhawm tuaj yeem tsim cov kav dej luv, thiab tus nqi tshwj xeeb yog qhov siab tshaj plaws hauv kev txhim kho hluav taws xob hauv ntiaj teb.
Thaum vuam seamless steel kav hlau kav nrog sib nqus, peb feem ntau pom kev sib nqus ntawm arc hauv cov hlau sib nqus, thiab slag melt splashing los ntawm lub vuam da dej. Txhawm rau txhawm rau cov txheej txheem vuam thiab txhim kho qhov zoo ntawm welded sib koom ua ke, cov yeeb nkab hlauetized yuav tsum demagnetized ua ntej vuam. Nws yog qhov nyuaj kom ua tiav demagnetization ntawm welded steel yeeb nkab, yog li vuam yog tso cai thaum lub sijhawm muaj kev cuam tshuam tsis txaus los cuam tshuam rau vuam zoo.
