Cold Rolled Coil Qhov txawv

Chev phaj yog ib hom phaj nyob rau hauv steel, uas yog ib tug nyias steel phaj uas yog ntev thiab nqaim thiab muab nyob rau hauv yob.
Lub ntim thiab phaj yog yuav luag ib pob txiav
Chilled coil yog kub dov kauj los ntawm pickling thiab txias dov. Nws tuaj yeem hais tau tias nws yog hom txias dov ntawv coil.
Cold rolled coil (annealed): kub dov kauj yog tau los ntawm pickling, txias dov, hood annealing, leveling, (tiav).
Muaj peb qhov sib txawv tseem ceeb ntawm ob:
1. Nyob rau hauv tsos, lub dav chilled kauj yog me ntsis faint.
2. nto zoo, qauv, qhov tseeb qhov tseeb thiab lwm yam txias -rolled phaj yog zoo dua txias- dov phaj.
3. nyob rau hauv cov nqe lus ntawm kev ua tau zoo, vim qhov txias - dov kauj ncaj qha tau los ntawm txias - dov txheej txheem, qhov txias - dov coil tshwm sim ua hauj lwm hardening thaum lub sij hawm txias dov, ua rau kom muaj zog yield thiab seem seem ntawm cov kev ntxhov siab sab hauv, thiab kev ua haujlwm sab nraud yog "nyuaj", yog li nws yog hu ua txias coil {{4}.
Yog li ntawd, lub zog tawm los: qhov txias -rolled coil yog ntau dua qhov txias -rolled coil (annealed), uas ua rau txias -rolled coil (annealed) ntau conducive rau stamping.
Feem ntau, qhov kev xa khoom tsis zoo ntawm lub tshuab txias txias yog annealed.
