1. Ob qhov tseem ceeb sib txawv
(1) Cov ntsiab lus ntawm cov khoom siv txias txias: txias dov steel yog cov hlau uas ua los ntawm txias dov. Txias dov yog ntxiv nyias cov hlau 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 recrystallization kub.
2. Lawv cov yam ntxwv 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 ua cov khoom.
(2) Cov yam ntxwv ntawm kub dov steel: siab plasticity ntawm hlau thaum kub dov, tsis tshua muaj 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, cov nplej ntxhib hauv lub xeev casting yuav tawg, cov kab nrib pleb yuav kho tau zoo, qhov tsis xws luag casting yuav raug txo los yog tshem tawm, raws li cov qauv cam khwb cia yuav hloov mus rau deformed. qauv, thiab cov khoom ua ntawm alloys yuav raug txhim kho.
