Sib txhuam hauvkev zamyog kev sib txhuam ntawm ob cov hlau ntawm cov sib xyaw sib txawv thiab cov khoom (alloys), ntawm cov hlau muag muag (workpiece) thiab tawv hlau (tuag). Nyob rau hauv rooj plaub ntawm tsis muaj lubrication, yog kev tiv tauj sib txhuam ntawm ob hom hlau saum npoo av oxide zaj duab xis; Nyob rau hauv lub lubrication mob, tiv tauj kev sib txhuam ntawm cov xim oxide ntawm ob txheej sib npaug ntawm cov haujlwm hauv lub zog, thiab tseem tsis tau ua rau oxidized thiab muaj ib tug zoo adsorption zog, Thiab kev sib txhuam ntawm lubricating nruab nrab thiab saum npoo ntawm kev tuag thiab kev sib txhuam tiag tiag (tiv toj) yog nce.

Vim yog cov kev sib txhuam cov yam ntxwv nruab nrab ntawm qhov khoob thiab kev sib chiv sib chwv hauv lubForging txheej txheem, cov txiaj ntsig hauv qab no yuav ua rau muaj tseeb:
(1) deformation quab yuam nce los ntawm 10% vim kev sib txhuam, thiab kev siv zog nce raws li;
(2) kev sib txhuam ua rau tsis ncaj ncees ntawm kev lom zem ntawm kev lom zem, kom cov qauv sib dhos sab hauv thiab kev ua tau zoo, thiab cov khoom txo qis;
(3) Kev ua yeeb yaj kiab ua rau txo qis ntawm cov duab ntsuas duab thiab muaj kev pom zoo ntawm kev zam txim, uas ua rau cov ntawv cuav, uas ua rau cov ntawv cuav tawm thaum cov lus tsis lees paub thaum cov neeg tsis txaus ntseeg;
(4) kev sib txhuam ua rau kev coj ua kom hnyav dua thiab ua rau nws lub neej hnyav;
(5) Ua kom muaj kev sib txhuam hauv zos tsis kam ntawm cov kab noj hniav tuaj yeem ua rau cov kab noj hniav uas tsis yooj yim sua kom sau tus nqi sib sau ncaj thiab txo tus nqi tsis lees paub.
Nws tuaj yeem pom tias kev sib txhuam ntawd yog rab ntaj ob sab hauvForging Ntau Lawm, uas muaj ob qho zoo thiab tsis zoo. Yog li ntawd, txoj kev sib txhuam hauv cov txheej txheem forging yuav tsum raug tswj hwm kom ntseeg tau tias cov txheej txheem forging ib txwm muaj.
