G80 Galvanized Lifting Alloy Steel Link Chain Kev muag khoom

Kev kho cua sov ntawm cov saw nqa yog ib qho tseem ceeb tsim nyog cov txheej txheem, thiab nws cov txheej txheem muaj xws li: carburizing, nitriding, quenching, tempering, annealing, normalizing, carbonitriding, boronizing, thiab lwm yam. Thaum tshav kub kub kev kho mob tuaj yeem nqa cov khoom tseem ceeb xws li deg hardness thiab toughness. saw hlau. Cov nram qab no luv luv qhia txog qee qhov kev nkag siab zoo ntawm kev kho cua sov ntawm kev nqa chains. quenching yog ib txoj kev kho cua sov heev hauv kev tsim cov saw hlau, nrog kev ua haujlwm siab quenching thiab muaj peev xwm coj tau qee qhov tawv tawv rau cov saw hlau. Annealing, normalizing, tempering: Cov kev kho cua sov no yog ua kom sov cov hlau thiab ua kom sov rau ib lub sijhawm, tsis tas yuav tsum muaj kua nruab nrab kom txias. Ntawm lawv, cov txheej txheem tempering yog nqa tawm tom qab quenching, uas tuaj yeem txo qhov hardening, quenching kev ntxhov siab thiab nce toughness.
