Annealing kev kho mob
Annealing yog txheej txheem kev kho cua sov hlau uas hais txog cua sov cov hlau maj mam mus rau qhov kub thiab txias, ua kom lub sijhawm txaus, thiab tom qab ntawd txias ntawm qhov tsim nyog ceev.Lub hom phiaj yog kom txo qis hardness, txhim kho kev txiav thiab kev ua haujlwm; txo qhov seem kev ntxhov siab, stabilize qhov loj me, txo deformation thiab tawg nyiam; kho Microtissue, thiab tshem tawm cov teeb meem Microtissue.
Kev kho mob
Kev kho mob yog hais txog cov txheej txheem kev kho cua sov ntawm cov cua sov ntawm cov hlau mus rau qhov kub siab ib-theem cheeb tsam ntawm qhov kub thiab txias, yog li ntawd cov theem dhau los yog siab yaj mus rau hauv cov kua dej tom qab txias sai, thiaj li yuav tau txais cov kua dej oversaturated.
normalizing kev kho mob
Normalizing kho yog kev kho cua sov uas txhim kho cov hlau toughness. Tom qab cua sov cov hlau mus txog 30-50 ℃ saum ac3 qhov kub thiab txias, khaws cia rau lub sijhawm, tom qab ntawd txias hauv huab cua. nyob rau hauv me ntsis txias ceev ceev, uas yuav tsis tau tsuas yog txaus siab rau lub zog, tab sis kuj yuav ho txhim kho lub toughness (akv tus nqi) thiab txo cov cracking nyiam ntawm cov khoom.
Tempering kho
Tempering kev kho mob yog ib txoj kev kho mob uas txias steel tom qab hardened los yog normalized kev kho mob uas qis dua qhov kub thiab txias rau ib lub sij hawm los ua kom lub toughness ntawm cov khoom.
Kev kho mob quenching
Quenching yog txheej txheem kev kho cua sov uas ua kom sov cov hlau mus rau qhov kub ntawm austenite, qhov kub thiab txias ac3 (sub-coanalysis steel) lossis ac1 (over-coanalysis steel), kom tau txais tag nrho lossis ib feem ntawm austenite, tom qab ntawd txias sai rau kev hloov ntawm martensite.
Induction hardening
Induction hardening yog txoj kev quenching uas siv electromagnetic induction kom sov qhov chaw sai sai thiab txias nws ceev.
