1. Carburizing: Ib hom tshuaj kho cua sov uas muaj cov kab C uas kis tau rau hauv cov hlau ntawm thaj tsam uas muaj qee cov tshuaj chemical hauv ib qho kub. Ib nrab preheating (850 ° C) carburizing (890 ° C) diffusion (840 ° C) txheej txheem
2, quenching: carbon thiab tsawg hlau alloy steel, feem ntau siv quenching los yog ib tug quenching.
3. Kev kub ntxhov: kub kub kom tsis txhob muaj kev ntxhov siab thiab txhim kho lub zog thiab kev muaj zog ntawm cov txheej txheem ntawm lub cev. Qhov kub ntawm qhov nruab nrab ntawm cov leeg ntawm peb lub tuam txhab yog li 360 ° C, thiab tus kheej qhov drilling screws (phab ntsa phom rau tes) muaj kub kub txog 200 ° C, thiab tom qab txias rau 34-35 ° C thiab 39-40 ° C feem.
Ntsia hlau ua kom tsis muaj teeb meem, ntsia hlau ua kom sov, kev sib tw hauv SMEs, yuav tsis muaj lub tshuab fais fab rau tus kheej ntawm lub tuam txhab. Feem ntau, nws yog qhov yuav tsum tau xa nws mus rau ib qho kev cob qhia thiab lub Hoobkas zog. Yog li ntawd, peb lub tuam txhab uas ua rau screws attaches kuj zoo kawg thiab tseem ceeb rau kev xaiv ntawm tshav kub kho nroj tsuag. Yuav xaiv ib qho tsim nyog tus nqi, qhov zoo ntawm lub viav vias tom qab kev kho cua kub yog qhov zoo tshaj plaws.
