Qhov txawv ntawm kub dov thiab txias dov ntawm stainless hlau yog tias txias dov yog dov los ntawm lub hauv paus ntawm kub dov.
Txias Rolling: It is processed and rolled on the basis of hot-rolled stainless steel sheets and coils. Generally speaking, it is a process of hot rolling → pickling → cold rolling. Although the steel plate will heat up due to rolling during processing, it is still called cold rolling. Due to the continuous cold deformation of hot rolling, the mechanical properties are relatively poor and the hardness is too high. It must be annealed to restore its mechanical properties, and those without annealing are called hard rolled coils. Hard rolled coils are generally used to make products that do not require bending or stretching.
Nws nta:
1. Vim muaj qee qhov kev ua haujlwm hardening, txias- cov ntawv hlau dov muaj qhov toughness tsawg thiab kim dua;
2. Cov khaub thuas- dov nto tsis muaj oxide nplai, thiab qhov zoo yog qhov zoo;
3. Cov khoom ua los ntawm txias deformation muaj qhov siab qhov tseeb thiab qhov zoo ntawm qhov chaw;
4. Cold rolling yog dav siv nyob rau hauv txhua qhov chaw ntawm lub neej vim nws cov txheej txheem ntau lawm, xws li txhua yam txias stamping qhov chaw, txias dov txias extrusion profiles, txias coil springs, txias drawn xov hlau, txias taub hau bolts, thiab lwm yam.
Kub dov:Piv nrog rau txias dov, txias dov yog dov hauv qab qhov kub ntawm recrystallization, thaum kub dov yog dov ua saum toj no lub recrystallization kub.
Nws nta:
1. Lub toughness thiab nto flatness tsis zoo, thiab tus nqi qis;
2. Qhov kub ntawm kub dov yog zoo ib yam li forging;
3. Lub phaj kub yog kub dov thiab muaj oxide daim tawv nqaij ntawm qhov chaw, thiab lub thickness ntawm lub phaj yog txawv;
4. Vim nws cov txheej txheem tsim khoom, nws yog siv rau ntau yam kev siv pej xeem, xws li cov khoom siv hauv tsev, cov khoom siv hauv tsev, thiab lwm yam;
5. Cov khoom siv hluav taws xob ntawm kub- cov ntawv hlau dov yog qhov qis dua rau kev ua haujlwm txias thiab forging, tab sis lawv muaj qhov zoo dua toughness thiab ductility.
