Kev kho cua sov hlau yog ib qho ntawm cov txheej txheem tseem ceeb hauv kev tsim cov tshuab. Piv nrog rau lwm cov txheej txheem ua, kev kho cua sov ntawm American standard channel steel feem ntau tsis hloov cov duab thiab tag nrho cov tshuaj muaj pes tsawg leeg ntawm lub workpiece, tab sis hloov lub internal microstructure ntawm lub workpiece, los yog hloov cov tshuaj muaj pes tsawg leeg ntawm lub workpiece nto muab los yog txhim kho. kev ua haujlwm ntawm lub workpiece.
Nws cov yam ntxwv yog los txhim kho qhov zoo ntawm cov khoom ua haujlwm, uas feem ntau tsis pom ntawm qhov muag liab qab. Txhawm rau ua kom cov hlau ua haujlwm muaj cov khoom siv kho tshuab, lub cev thiab cov khoom siv tshuaj lom neeg, ntxiv rau kev xaiv cov khoom tsim nyog thiab ntau yam txheej txheem, cov txheej txheem kho cua sov feem ntau yog qhov tseem ceeb.
Hlau yog cov khoom siv dav tshaj plaws hauv kev lag luam machinery. Lub microstructure ntawm steel yog complex thiab tuaj yeem tswj tau los ntawm kev kho cua sov. Yog li ntawd, kev kho cua sov ntawm American standard channel steel yog cov ntsiab lus tseem ceeb ntawm kev kho cua sov hlau. Tsis tas li ntawd, txhuas, tooj liab, magnesium, titanium, thiab lwm yam thiab lawv cov alloys kuj tuaj yeem hloov lawv cov khoom siv kho tshuab, lub cev thiab tshuaj lom neeg los ntawm kev kho cua sov kom tau txais cov khoom sib txawv.
