Muaj peb qhov sib txawv ntawm cov hlau txias txias thiab kub dov hlau
1. Lub ntsiab lus ntawm ob qhov sib txawv
(1) Cov ntsiab lus ntawm cov khoom siv txias txias: Cov hlau txias txias yog cov hlau ua los ntawm cov dov txias.Txias dov yog cov txheej txheem ntawm ntxiv dov steel phaj rau lub hom phiaj thickness ntawm chav tsev kub.
(2) Cov ntsiab lus ntawm cov hlau kub kub: Kub dov hlau yog ib hom hlau dov saum toj no qhov kub ntawm recrystallization.
2. Cov yam ntxwv ntawm ob qhov sib txawv
(1) Cov yam ntxwv ntawm txias dov steel: Lub thickness ntawm txias dov steel phaj yog ntau dua, thiab nto yog du thiab zoo nkauj.Nyob rau tib lub sij hawm, nws kuj muaj ntau yam superior mechanical zog, tshwj xeeb tshaj yog nyob rau hauv cov nqe lus ntawm kev ua tau zoo.
(2) Cov yam ntxwv ntawm kub dov steel: Thaum lub sij hawm kub dov, cov hlau muaj siab plasticity thiab tsawg deformation kuj, zoo heev txo lub zog noj ntawm hlau deformation.Kub dov tuaj yeem txhim kho kev ua haujlwm ntawm cov hlau thiab alloys, uas yog, crushing ntawm coarse nplej nyob rau hauv lub xeev casting, tseem ceeb tawg kho, txo los yog tshem tawm cov tsis xws luag casting, transforming lub as-cam khwb cia qauv rau hauv ib tug deformed qauv, thiab kev txhim kho cov txheej txheem. kev ua haujlwm ntawm alloys.
3. Cov txheej txheem ua tiav rau ob qhov sib txawv
(1) Cov txheej txheem ua haujlwm rau cov hlau txias txias: Cov hlau txias txias yuav tsum muaj lub zog zeb siab, ua haujlwm qis qis, thiab nruab nrab annealing kom tshem tawm kev ua haujlwm nyuaj thaum lub sijhawm dov, yog li tus nqi kuj tseem siab.
(2) Cov txheej txheem ua haujlwm rau kub dov hlau: Kub dov hlau yog yooj yim rau yob thiab muaj kev ua haujlwm siab dov.Qhov kub dov kub suav nrog qhov pib dov kub thiab qhov kawg dov kub.Qhov pib dov kub yog txiav txim siab los ntawm kwv yees li 80% ntawm qhov kub thiab txias nyob rau hauv daim duab alloy theem, thaum lub sij hawm ua tiav dov kub yog txiav txim siab raws li daim duab alloy lub plasticity daim duab, uas yog feem ntau tswj saum cov alloy lub recrystallization kub.
