Dab tsi yog cov txheej txheem tseem ceeb rau Q235COIL?
Cov txheej txheem tseem ceeb yog kub dov: nruam casting billet → cua sov → ntxhib dov → tiav dov → coiling; txias dov kuj tseem siv rau nyias - ntsuas, siab - cov khoom muaj tseeb.
Qhov txawv ntawm kub- dov thiab txias- dov Q235COIL yog dab tsi?
Kub- dov: thickness 1.5 ~ 20mm, nto oxidation, dav dav, tus nqi qis; Txias - dov: thickness 0.3 ~ 3.0mm, du nto, siab qhov tseeb, me ntsis zog dua.
Coiling kub cuam tshuam li cas rau kev ua haujlwm?
Kub coiling ntau dhau ua rau coarse nplej thiab txo lub zog; Qhov kub tsawg dhau los ua rau muaj kev ntxhov siab sab hauv thiab ua rau muaj kev cuam tshuam ntawm kev sib kis.
Dab tsi yog qee qhov kev tsis zoo ntawm qhov chaw?
Cov no feem ntau muaj xws li hlau oxide nplai, pitting, khawb, transverse creases, ntug kab nrib pleb, thiab lwm yam, cuam tshuam rau kev ua haujlwm tom ntej thiab zoo li qub.
Yuav tswj cov ntawv zoo li cas?
Los ntawm optimizing dov quab yuam, yob qhov sib txawv, thiab cua txias tswj, yas thiab waviness raug tswj kom txo qis kev ntxhov siab sab hauv.
