Galvanized Steel Coils PRIME Kub Rolled Chev

Dab tsi yog qhov prime kub dov coil?

Prime kub dov kauj yog cov khoom zoo, qib siab-qib steel kauj uas tau kub dov thiab ua tiav kom ua tiav cov qauv kev lag luam thiab cov neeg siv khoom tshwj xeeb. Lo lus "prime" txhais tau hais tias lub kauj yog tsis muaj qhov tsis zoo ntawm qhov chaw, xws li corrosion, scaling, lossis blemishes, uas tuaj yeem cuam tshuam nws txoj haujlwm lossis kev ntxim nyiam.

Prime kub dov coils yog tsim los siv cov txheej txheem kub dov nyob rau hauv uas steel slabs yog rhuab saum lawv cov recrystallization kub thiab thawb los ntawm ib tug series ntawm rollers kom txo thickness thiab puab cov hlau mus rau hauv ib tug coil daim ntawv. Cov txheej txheem no muab cov hlau zoo rau txhua yam zoo, xws li muaj zog, ductility, thiab formability.

Prime kub dov coil manufacturing txheej txheem

Prime kub dov coils yog tsim nyob rau hauv ntau theem. Nov yog cov ntsiab lus dav dav ntawm cov txheej txheem:

Steelmaking

Cov txheej txheem steelmaking pib nrog melting ntawm hlau ore, seem steel, thiab lwm yam ntaub ntawv alloying nyob rau hauv lub cub tawg. Ob lub thev naus laus zis tseem ceeb yog Cov Hluav Taws Xob Hluav Taws Xob Hluav Taws Xob (BOF) thiab Hluav Taws Xob Hluav Taws Xob (EAF). Txoj kev BOF tshem tawm cov impurities los ntawm cov hlau molten los ntawm tshuab oxygen rau hauv nws, whereas EAF txheej txheem melts seem hlau siv hluav taws xob arcs.
Nruam Casting

Tom qab lub molten hlau yog tsim, nws yog pub rau hauv ib tug nruam casting txheej txheem. Lub tshuab tas li nchuav cov hlau molten rau hauv dej-txias pwm, tsim cov khoom sib txuas. Cov strand yog ces txiav mus rau qhov ntev ntev, feem ntau nyob rau hauv daim ntawv ntawm slabs los yog billets.

Rov ua dua

Cov slabs los yog billets yog warmed nyob rau hauv ib lub qhov cub kom kub siab tshaj lawv recrystallization kub. Qhov kub no ib txwm nyob nruab nrab ntawm1100 thiab 1250 degree. Reheating softens cov hlau thiab npaj nws rau cov txheej txheem dov tom ntej.
