Yuav ua li cas kom paub qhov txawv ntawm cov khoom siv thiab qhov zoo sib txawv ntawm cov ntsia hlau khiav

QIB KHOOM:

Cov ntsia hlau zoo: Ua los ntawm cov hlau sib xyaw ua ke muaj zog (xws li 40Cr, 42CrMo, hlau qib),
nrog lub zog tensile ntawm ≥ 800MPa thiab qhov nyuaj ntawm HRC 22-32, muaj peev xwm tiv taus kev cuam tshuam hnyav.

Cov ntsia hlau tsis zoo: siv cov hlau carbon zoo tib yam (xws li Q235), nrog lub zog tensile qis (kwv yees li 400MPa), yooj yim deformation lossis tawg.

Cov txheej txheem kho cua sov:

Cov bolts zoo yuav tsum tau dhau los ntawm kev kho quenching thiab tempering (quenching + high-temperature tempering),
nrog rau qhov chaw sib xws thiab qhov nyuaj ntawm lub hauv paus thiab tsis muaj txheej decarburization.

Cov khoom tsis zoo yuav tsis kho cua sov lossis muaj cov txheej txheem tsis zoo, ua rau qhov nyuaj tsis sib xws (qhov chaw tawv, lub plawv mos) thiab yooj yim tawg.
