Lub zog ntawm cov kauv raj feem ntau yog siab tshaj qhov ncaj seam welded yeeb nkab. Nws tuaj yeem siv cov yeeb nkab welded nrog ib txoj kab uas loj dua ntawm cov khoom siv billet, thiab tseem tuaj yeem siv tib qhov dav los tsim ib lub raj nrog cov kav dej sib txawv nrog cov kav dej sib txawv. Txawm li cas los xij, piv nrog tib qhov ntev ntawm tib qhov ntev, qhov ntev ntawm qhov vuam yog nce los ntawm 30 ~ 100%, thiab qhov ceev ntau lawm yog qis dua. Yog li ntawd, feem ntau ntawm cov me me-caliber welded kav yog welded nrog ncaj seams, thiab feem ntau ntawm cov loj-caliber welded kav yog feem ntau muab kauv welded.
1. Tiag seam high-frequency vuam steel yeeb nkab
High-frequency welding txoj cai: Tom qab kub-dov curly phaj yog tsim los ntawm kev sib sau, cov nyhuv ntawm daim tawv nqaij thiab cov nyhuv uas nyob ib sab ntawm high-frequency tam sim no yog siv los ua kom sov cov npoo ntawm lub raj billet, thiab lub siab vuam yog ua raws li qhov kev txiav txim ntawm lub nyem cov menyuam kom ua tiav cov yeeb nkab steel.
High-frequency welded steel yeeb nkab yam ntxwv: Sab hauv thiab sab nraud welds ntawm ERW welded kav yog scraped rau niam cov khoom. Lub geometric loj yog siab, concentricity siab, phab ntsa thickness yog uniform, lub vuam yog uniform tom qab kev kho cua sov ntawm lub tshav kub, thiab seamless steel yeeb nkab yog siab npaum li cov seamless steel yeeb nkab. Anti-squeezing peev xwm.
2. Lub kaum sab xis ntawm lub vuam ntawm cov kav hlau txuas txuas feem ntau yog 50-75 degrees, uas txhais tau hais tias qhov kev ntxhov siab hluavtaws ntawm cov kauv vuam yog 60-85% ntawm qhov kev ntxhov siab tseem ceeb ntawm txoj kab ncaj nraim. Qhov no txhais tau hais tias cov kauv raj tuaj yeem me dua li cov phab ntsa ntawm cov kav dej ncaj nraim welded thaum tib lub zog ua haujlwm. Qhov no feature tsis tsuas yog txo tus nqi ntawm kev tsim khoom, tab sis kuj txo cov kev siv hluav taws xob thiab kev ua qias tuaj ib puag ncig. Tsis tas li ntawd, cov kauv steel yeeb nkab kuj muaj qhov zoo ntawm kev ua haujlwm siab, tus nqi qis, thiab hloov tau yooj yim, yog li nws tau siv dav hauv ntau qhov chaw.
