Rolling yog ib qho ntawm cov txheej txheem tseem ceeb hauv kev ua hlau. Nws tsuas yog siv siab rau hlau billets (xws li steel, aluminium, tooj liab, thiab lwm yam) los ntawm dov mills kom lawv plastically deform, yog li tau txais cov khoom xws li phaj, kav, profiles, xov hlau, thiab lwm yam, nrog rau cov duab, qhov ntau thiab tsawg, thiab cov khoom.
1. Hom dov zeb hom
Ob- yob zeb: cov qauv yooj yim, siv rau kev qhib lub pob zeb los yog yob yob;
Plaub- yob zeb: zoo ua hauj lwm yob (txo dov quab yuam) thiab coarse txhawb yob (nce rigidity), dav siv rau phaj thiab sawb dov;
Multi- yob zeb: tsis tshua muaj siab rigidity, siv rau nyias nyias strips (xws li ntawv ci, thickness tsawg dua los yog sib npaug zos rau 0.05mm) los yog siab hardness cov ntaub ntawv (xws li stainless hlau, titanium alloy);
Nruam rolling mills: ntau lub dov mills tau txuas nrog hauv cov koob kom ua tiav cov dov tsis tu ncua thiab kev ua haujlwm siab.
2. Kev faib tawm

Kub Rolling (Kub Rolling)
Cov yam ntxwv ntawm tus txheej txheem: lub billet yog rhuab mus rau saum toj no lub recrystallization kub, nrog zoo plasticity thiab tsawg deformation kuj, haum rau loj deformation ua.
Daim ntawv thov scenarios: zus tau tej cov phaj nruab nrab thiab tuab, kub- dov coils, steel seem, seamless yeeb nkab billets, thiab lwm yam., feem ntau siv rau billet qhib thiab ua ntej tsim.
Qhov zoo: kev siv hluav taws xob tsawg, kev ua haujlwm siab, tuaj yeem tshem tawm qhov tsis xws luag; Disadvantages: nto oxidation, tsis tshua muaj qhov tseeb.

Txias Rolling
Cov yam ntxwv txheej txheem: dov nyob rau hauv chav tsev kub (los yog me ntsis rhuab), deformation nyob rau hauv lub recrystallization kub, intermediate annealing yuav tsum tau tshem tawm ua hauj lwm hardening.
Daim ntawv thov scenarios: ntau lawm daim hlau nyias, sawb hlau (xws li automotive panels, steel rau cov khoom siv hauv tsev), siab - cov kav dej / cov xaim, nrog rau qhov zoo ntawm qhov chaw thiab qhov yuav tsum tau muaj qhov tseeb.
Qhov zoo: du nto, qhov siab qhov tseeb (thickness kam rau ua ncav cuag ± 0.01mm), cov koom haum tsis sib xws. Disadvantages: siab deformation kuj, siab zog noj, thiab tom qab annealing yuav tsum tau.
- Kev faib tawm los ntawm cov khoom lag luam
- Phaj dov: kev tsim cov phaj nruab nrab thiab tuab, daim hlau nyias.
- Tube dov: seamless yeeb nkab (perforation + extension), welded yeeb nkab (welding tom qab phaj sib sau);
- Hlau / bar dov: hlau rau vuam, bar rau txhua yam khoom.
FANMETAL muaj cov cuab yeej dov siab heev thiab cov kws tshaj lij los tsim thiab siv, thiab tuaj yeem muab cov neeg siv khoom zoo siab - zooZirconium Rolled Sheets, Gr2 Titanium Tubes, 99.95% Molybdenum Foils, thiab lwm yam khoom uas tsis yog-ferrous hlau ua tom qab siab-precision dov ua.
