Txias-rolled steel
Txias dov ua rau cov hlau nrog ze dua qhov ntev kam rau ua thiab ntau qhov chaw ua tiav ntau dua li kub dov. Nws kuj yogmus txog 20% muaj zog dua kub dovlos ntawm kev siv lub zog hardening.
Cold -rolled steel yog dab tsi?
Txias-rolled steel yog ib hom hlau ua tiav ntawm chav tsev kub los ntawm compression ntawm chais kom ua tiav qhov ntev dua, smoother nto tiav, thiab txhim kho cov khoom siv kho tshuab. Tsis zoo li kub-rolled steel, uas yog tsim nyob rau hauv high temperatures saum lub recrystallization point, txias-rolled steel mus los ntawm ntxiv txo cov kauj ruam uas refine nws cov qauv thiab txhim khu nws lub zog. Vim li no, kev lag luam xws li tsheb, khoom siv hauv tsev, kev tsim kho, thiab kev tsim khoom siv tau dav siv txias- cov qib dov vim lawv qhov sib xws thiab tsim tau.
Nkag siab seb qhov txias txias -rolled steel muaj zog dua li "tsis tu ncua" steel yuav tsum tau qhia meej tias "cov hlau tsis tu ncua" hais txog dab tsi. Feem ntau, cov hlau tsis tu ncua hauv kev ua lag luam txhais tau tias kub - dov steel, paub txog nws tus nqi qis dua tab sis kuj txo qis qhov raug thiab ua haujlwm tsis muaj zog me ntsis. Txias- dov tsis hloov cov tshuaj muaj pes tsawg leeg ntawm cov hlau, tab sis lub zog hardening nyhuv tsim thaum lub sij hawm compression ho nce nws lub zog thiab hardness.
Mechanical Property Comparison
Hauv qab no yog ib qho yooj yim sib piv ntawmtxias - dovthiabkub- dov (tsis tu ncua) steellos piav txog qhov sib txawv:
| Khoom | Txias-Rolled Steel | Kub-Rolled (Regular) Steel |
|---|---|---|
| Nto tiav | Zoo heev, ci | Rough, nplai ntawm qhov chaw |
| Dimensional raug | Siab | Nruab nrab |
| Yield zog | Siab dua vim muaj zog hardening | qis |
| Tensile zog | Siab dua | qis |
| Formability | Zoo heev, ruaj khov | Zoo tab sis tsis sib xws |
| Cov ntawv thov siv | Automotive panels, khoom siv, precision Cheebtsam | Kev tsim kho kab teeb, qhov chaw ua haujlwm |
Los ntawm cov lus saum toj no, nws yog qhov tseeb tiastxias- dov steel feem ntau muaj zog dua li cov hlau tsis tu ncua, tshwj xeeb tshaj yog nyob rau hauv yield zog thiab tensile zog. Kev ua haujlwm ntxiv thaum lub caij txias yuav ua rau kom muaj qhov sib txawv ntawm qhov sib txawv hauv cov hlau microstructure, ua rau nws nyuaj thiab ruaj khov.
Yog vim li cas txias -Rolled Steel muaj zog dua
- Hnyav Hardening
Thaum lub sij hawm txias dov, cov hlau tau dhau los ua cov yas deformation ntawm qhov kub thiab txias, tsim kom muaj kev ntxhov siab sab hauv uas ua rau muaj zog hardness thiab yield zog.
- Refined Microstructure
Cov menyuam compression rearrange cov hlau cov nplej rau hauv cov qauv denser, txhim kho qhov sib xws thiab kev ua haujlwm txhua yam.
- Zoo Qhov Nto Zoo
Qhov saum npoo du yuav txo tau qhov muaj peev xwm ntawm kev ntxhov siab, pab tswj kev ua kom muaj zog.
- Ntau ruaj khov Mechanical Properties
Txias-rolled steel muab cov tuab tuab thiab txhim khu kev tiv thaiv, ua rau nws haum rau precision engineering.
Daim ntawv thov qhov muaj zog tseem ceeb
Kev lag luam uas xav tau kev ua haujlwm siab dua feem ntau xaiv txias -rolled steel rau:
- Automotive stamping qhov chaw
- Cov khoom siv hauv tsev
- Rooj tog kho vajtse
- Hlau txee thiab lockers
- Precision raj
- Cov khoom siv hluav taws xob
Kub- dov steel tseem yog qhov kev xaiv zoo tshaj plaws hauv kev siv cov qauv hnyav uas tus nqi tseem ceeb tshaj qhov tseeb.
Txias-rolled steel yeej muaj zog dua li niaj zaus kub-rolled steel vim strain hardening, txhim kho nto tiav, thiab siab dua qhov tseeb. Rau cov tuam txhab nrhiav siab -zoo, precision-engineered txias- cov ntaub ntawv dov,GNEE STEELmuaj ntau yam khoom xws liDC01, DC03, DC04, DC05, DC06, SPCC, SAE1008, thiab kev cai txias- dov coils thiab nplooj ntawv. Nrog kev ruaj khov zoo thiab kev xa tawm thoob ntiaj teb, GNEE STEEL yog tus khub zoo tshaj plaws rau koj qhov txias txias -rolled steel kev xav tau.
