Tus nqi thiab zoo ntawm txias drawn hlau khoom.High-zoo txias-draw hlau cov khoom yog tsim los ntawm cov tuam txhab muaj zog, yog li qhov zoo yog guaranteed, thiab tus nqi yog ib txwm kuj siab dua. Peb txhua tus paub tias qhov zoo yog ncaj qha proportional rau tus nqi, thiab qhov zoo yog xav txog tus nqi. Cov khoom muaj kev cuam tshuam tus nqi.Qhov kev tshuaj xyuas ntawm cov khoom siv txias rub tawm tau lees paub qhov zoo.L loj, cov chaw lag luam raug cai muaj qhov tsis sib xws hauv cov khoom lag luam thiab cov qauv tshuaj xyuas zoo.Cov tuam txhab zoo yuav muaj cov khoom siv ntau dua.Raws li qib txias deformation nce, lub zog tensile, hardness thiab elasticity ntawm txias rub hlau nce, thiab elongation thiab txo ntawm cheeb tsam txo.Vim lub hav zoov ntawm kev ua hauj lwm hardening, thaum lub degree ntawm tensile deformation ncav cuag ib tug tej yam kev txwv, lub txias ua hauj lwm kev kawm ntawm cov hlau hlau yog ho txo. Thaum nws tsis tsim nyog rau kev kos duab tas mus li, peb txo qhov kev sib txhuam, txo cov duab kos thiab pwm noj, thiab tau txais cov khoom tiav, qhov loj me thiab cov khoom uas xav tau cov duab yuav tsum tau lubricated nrog lubricating roj.
Thaum siv cov roj nplua nyeem, nws yog hu ua qhuav hlau kos duab; Lub hom phiaj ntawm kev tshem tawm cov nplais oxide yog los tiv thaiv oxidation ntawm cov hlau kos duab cam khwb cia hlau los ntawm kev puas tsuaj rau saum npoo ntawm cov pwm thiab cov hlau, thiab cov txheej txheem tom ntej los yog txheej txheej muaj qhov zoo ntawm qhov chaw, txo kev sib txhuam thiab txo cov duab kos.Muaj. ob hom descaling txoj kev, chemical method thiab mechanical method.
