Kev Tsim Kho Tshuab

Self Tapping Ntsia Hlau:

1. Kev kho cua sov: Nws yog ib txoj hauv kev ua kom sov cov hlau rau qhov sib txawv thiab tom qab ntawd siv cov cua txias sib txawv kom ua tiav cov hom phiaj sib txawv ntawm kev hloov cov khoom ntawm cov hlau.Kev kho cua sov feem ntau yog: quenching, annealing, thiab tempering.Peb txoj kev no yuav ua li cas thiaj tsim tau?

2.Quenching: Ib txoj kev kho cua sov uas cov hlau yog rhuab mus rau saum 942 degrees Celsius kom cov hlau muaju nyob rau hauv austenitic lub xeev, thiab ces muab tso rau hauv dej txias los yog txias roj kom quench kom cov hlau muaju nyob rau hauv lub martensitic xeev.Txoj kev no tuaj yeem ua kom lub zog thiab hardness ntawm cov hlau.Muaj qhov sib txawv loj heev hauv lub zog thiab hardness ntawm cov hlau nrog tib daim ntawv lo tom qab quenching thiab tsis quenching.

3. Annealing: Ib txoj kev kho cua sov uas cov hlau tseem ua rau lub xeev austenitic thiab tom qab ntawd txias hauv huab cua.Txoj kev no tuaj yeem txo lub zog thiab hardness ntawm cov hlau, txhim kho nws yooj yim, thiab pab txhawb kev ua haujlwm.Feem ntau, steel yuav dhau los ntawm cov kauj ruam no ua ntej ua.

4. Tempering: Txawm hais tias nws yog quenched, annealed los yog nias-tsim, steel yuav tsim kev ntxhov siab nyob rau hauv, thiab qhov tsis sib xws ntawm kev ntxhov siab nyob rau hauv yuav cuam tshuam rau cov qauv thiab txhua yam khoom ntawm cov hlau los ntawm sab hauv, yog li yuav tsum muaj txheej txheem tempering.Cov khoom yog khaws cia kom sov tsis tu ncua ntawm qhov kub ntawm ntau tshaj 700 degrees, nws cov kev ntxhov siab sab hauv raug hloov thiab tom qab ntawd txias lawm.
