Qhov chaw hla ntu ntawm cov pas nrig sib nqus yuav tsum yog 70% - -75% ntawm thaj chaw hla ntawm lub raj sab hauv txoj kab uas hla. Hauv qab 70% ua rau txo qis hauv kev ua haujlwm zoo. Cov rods rau high-frequency welded raj yuav tsum muaj siab pib permeability, ua 800 saturated flux ceev Bs tus nqi siab tshaj 3000GS, siab npaum li qhov ua tau Curie kub thiab tsawg poob. Hauv kev siv, nws yuav tsum raug sau tseg tias qhov cua txias ntawm cov pas nrig sib nqus yuav tsum txaus los tiv thaiv cov pas nrig sib nqus los ntawm kev sib tsoo lossis qhov kub siab tshaj qhov Curie point. Qhov ntev thiab txoj hauj lwm ntawm tus pas nrig sib nqus yuav cuam tshuam rau kev ua haujlwm vuam. Daim duab saum toj no qhia txog qhov loj me ntawm cov txheeb ze induction nplhaib thaum vuam me me, nruab nrab thiab me me txoj kab uas hla steel kav. Nws yuav tsum tau muab sau tseg tias tag nrho cov cross-sectional cheeb tsam thiab ntev ntawm cov hlau nplaum siv yuav tsum tau kho raws li txoj kab uas hla loj ntawm welded steel yeeb nkab. Feem ntau, thaum vuam cov yeeb nkab loj-ntev, tag nrho qhov ntev ntawm cov hlau nplaum yuav luv dua, tab sis sab ntawm lub qhov qhib lub kaum sab xis tseem dhau ntawm cov kab nruab nrab ntawm cov menyuam extrusion.
