Dab tsi yog Kub Rolling rau Steel Coils?
Kub dov yog cov txheej txheem tsim khoom tseem ceeb rau steel coils, qhov twg steel billets tau rhuab mus rau 1100-1250℃(sab saum toj ntawm steel qhov kub ntawm recrystallization) los txhawb kev lag luam. Tsis zoo li txias dov (ua rau ntawm chav tsev kub), nws ua tau zoo ua cov tuab - ntsuas lossis loj- dav coils-zoo tagnrho rau kev siv cov qauv thiab kev lag luam.
Kev tsim khoom
Billet Cua sov:2-4 teev nyob rau hauv cheeb tsam tswj qhov cub (preheating → cua sov → soaking) kom zoo ib yam kub, tsis txhob muaj kev ntxhov siab.
Rough Rolling:3-5 hla mus rau nyias daim nyias nyias los ntawm 150-200mm mus rau 20-40mm.
Intermediate Rolling:2-3 hla mus rau 5-15mm, smoothing nto.
Ua tiav Rolling:5-7 mills mus rau qhov kawg 1.2-20mm thickness; laminar txias rau 550-650℃tswj microstructure.
Coiling:Mob rau hauv 5-30 tuj coils (puab txoj kab uas hla 508/610mm).
Tshaj tawm -Kev kho mob: Cua txias, tshuaj xyuas zoo, thiab ntim dej tsis zoo.

4. Daim ntawv thov tseem ceeb ntawm Kub Rolled Steel Sheet
Kev tsim kho: C/Z-beams, choj daim hlau, scaffolding.
Machinery: Lub hauv paus tshuab, hnyav- lub cev muaj zog.
Automotive: Tsheb thav duab, chassis qhov chaw.
Pipelines: Welded kav dej / roj / roj thauj.
Ntim thiab xa khoom
Peb muab qhov tseem ceeb heev rau kev nyab xeeb ntawm txhua yob ntawm cov hlau thaum thauj. Txhawm rau kom ntseeg tau tias cov khoom xa tuaj tsis raug, peb txais kev lag luam - txheej txheem ntim khoom:
Txhua yob yog ruaj ruaj nrog siab - lub zog steel bands kom tsis txhob xoob thaum thauj.
Kev tiv thaiv cov ces kaum ntxiv ntawm cov ntsiab lus sib txuas ntawm cov hlua hlau thiab cov hlau yob kom tsis txhob muaj kev puas tsuaj ntawm ntug.
Raws li cov neeg siv khoom xav tau, peb muab cov ntaub ntawv ya raws -cov ntaub ntawv pov thawj, cov ntaub npuag lossis cov ntim ntim puv kom txo tau xeb thiab khawb.
