Dab tsi yog Qhov Hardness Ntawm Cov Ntawv Txias Rolled

1. Cov ntawv txias-kuav los tiag
Qhov nyuaj ntawm cov ntawv txias txias yog feem ntau ntawm HRB1/2H=74~89 thiab 1/4H=65~80. Ntawm lawv, HRB yog hais txog Rockwell hardness, uas yog tus qauv rau kev ntsuas qhov softness thiab hardness ntawm cov ntaub ntawv. Tus nqi siab dua, cov khoom siv nyuaj dua. 1/2H thiab 1/4H xa mus rau qhov chaw ntawm kev sim hardness, nrog rau 1/2H qhia txog kev sim ntawm ib nrab ntawm lub thickness ntawm steel phaj thiab 1/4H qhia txog kev ntsuam xyuas ntawm ib feem peb ntawm lub thickness ntawm cov hlau phaj.
Ordinary txias-kuav los tiag steel daim hlau yog tsuas yog siv nyob rau hauv kev lag luam xws li kev tsim kho, tsheb, thiab cov khoom siv hauv tsev, yuav tsum tau muaj zog thiab hardness, nrog rau zoo plasticity thiab toughness. Nyob rau hauv lub tshav pob ntawm architecture, zoo tib yam txias-kuav los tiag ntawv yuav siv tau los ua lub teeb yuag steel qauv, sab nrauv phab ntsa panels thiab ru tsev ntawm high-sawv vaj tse, thiab lwm yam; Hauv kev lag luam khoom siv hauv tsev, nws tuaj yeem siv los ua lub plhaub sab nrauv thiab sab hauv cov khoom siv hauv tsev xws li tub yees thiab tshuab ntxhua khaub ncaws; Hauv kev lag luam tsheb, nws tuaj yeem siv los ua cov khoom siv lub cev, thav duab, thiab lwm yam.
2. Sib sib zog nqus kos txias-kuav los tiag steel phaj
Sib sib zog nqus-kub-kuav los tiag steel phaj yog hom txias-dov hlau phaj uas tau dhau los ua cov txheej txheem sib sib zog nqus, ua rau muaj zog dua thiab tawv dua, nrog rau zoo dua plasticity thiab toughness. Nws qhov hardness ntau yog feem ntau ntawm HRB1/2H=85~95 thiab 1/4H=70~80.
Cov ntawv sib sib zog nqus txias-kuav los tiag yog siv los tsim cov khoom uas xav tau lub zog siab, siab hardness, thiab zoo plasticity, xws li lub cev tsheb, hluav taws xob casings, thiab lwm yam. Vim yog cov txheej txheem sib sib zog nqus, cov hlau txias txias tuaj yeem tau txais cov nplej zoo. qauv thiab ntau zog, yog li muaj zoo formability thiab tej yam kuj.
3. Ultra sib sib zog nqus nqus daim ntawv txias-kuav los tiag
Ultra sib sib zog nqus daim duab txias-kuav los tiag steel phaj yog ib hom txias-dov hlau phaj ua tiav los ntawm ultra sib sib zog nqus nqus tshuab, uas muaj zog dua, hardness, thiab zoo dua plasticity thiab toughness. Nws qhov hardness ntau yog feem ntau ntawm HRB1/2H=80~90 thiab 1/4H=65~75.
