Yuav ua li cas los txhim kho lub hardness ntawm txias-kuav los tiag ntawv

Lub hardness ntawm cov ntawv txias-dov tuaj yeem txhim kho los ntawm cov txheej txheem hauv qab no
1. Kev kho cua sov
Kev kho cua sov yog ib txoj hauv kev zoo tshaj plaws los txhim kho cov tawv tawv ntawm cov ntawv txias-dov. Los ntawm kev tswj cov txheej txheem cua sov thiab cua txias ntawm cov ntawv txias-dov, cov qauv siv lead ua thiab cov tshuaj muaj pes tsawg leeg ntawm cov ntawv txias-dov tuaj yeem hloov pauv, yog li txhim kho lawv cov tawv tawv. Cov kev kho cua sov uas muaj xws li quenching, tempering, thiab normalizing.
2. Kev kho deg
Kev kho deg yog cov txheej txheem ntawm kev ua kom cov tawv tawv ntawm cov ntawv txias-dov los ntawm kev ntxiv ib txheej ntawm cov khoom nyuaj rau saum npoo. Cov kev kho saum npoo feem ntau muaj xws li nplaim taws txau, sandblasting, thiab pleev xim. Cov txheej txheem kev kho saum npoo no tuaj yeem ua rau saum npoo ntawm cov ntawv txias-dov smoother, thaum txhim kho lawv cov hardness thiab corrosion kuj.
3. Tshuaj kho mob
Kev kho tshuaj lom neeg yog cov txheej txheem ntawm kev ua kom lub zog ntawm cov ntawv txias txias los ntawm kev ntxiv ib txheej ntawm cov tshuaj chemical rau saum npoo ntawm daim ntawv. Cov kev kho tshuaj muaj xws li nitriding, hydrogen kho, thiab carbonitriding. Cov txheej txheem kev kho tshuaj no tuaj yeem txhim kho qhov nyuaj ntawm cov ntawv txias-kuav los tiag thiab tsim cov txheej txheem tiv thaiv nrog cov tawv tawv dua thiab muaj zog tiv thaiv corrosion nyob rau saum npoo ntawm cov nplooj ntawv txias.
