1. Normalization: Thaum tshav kub kub ntawm cov hlau los yog hlau mus rau qhov tseem ceeb ntawm AC3 los yog siab tshaj qhov kub thiab txias rau ib lub sij hawm ntawm lub sij hawm, thiab ces txias nws nyob rau hauv cov huab cua kom tau txais cov txheej txheem kev kho cua sov ntawm perlite qauv.
2. Annealing: Cov txheej txheem kev kho cua sov uas lub subconcentric steel workpiece yog rhuab mus rau 3-20 degrees saum AC40, tuav kub rau ib lub sij hawm, thiab ces maj mam txias (los yog faus rau hauv xuab zeb los yog txiv qaub) nrog rau lub cub. kom tsawg dua 500 degrees thiab txias hauv huab cua.
3. Kev kho cua sov: Cov hlau yog rhuab ntawm qhov kub tsis tu ncua nyob rau hauv qhov kub-kub ib-theem cheeb tsam, kom cov theem ntau dhau yog yaj tag rau hauv cov khoom tov, thiab tom qab ntawd txias sai sai kom tau txais cov txheej txheem kho cua sov ntawm supersaturated. kev daws teeb meem.
4. Kev laus: Qhov tshwm sim uas cov khoom ntawm cov alloy hloov lub sij hawm thaum nws muab tso rau ntawm chav tsev kub los yog me ntsis siab dua chav tsev kub tom qab kev kho cua sov los yog txias yas deformation.
5. Kev kho kev daws teeb meem: ua kom tiav ntau theem hauv cov hlau, ntxiv dag zog rau cov khoom siv thiab txhim kho toughness thiab corrosion kuj, tshem tawm kev ntxhov siab thiab softening, thiaj li mus txuas ntxiv ua thiab casting.
6. Kev laus kev kho mob: cua sov thiab ua kom sov ntawm qhov kub thiab txias ntawm qhov kev txhim kho theem nag lossis daus, kom cov theem txhim kho yuav los nag thiab nag, ua kom tawv thiab txhim kho lub zog.
7. Quenching: Cov txheej txheem kev kho cua sov uas cov hlau yog austenitized thiab quenched ntawm qhov tsim nyog txias kom ua rau lub workpiece mus rau qhov kev hloov pauv tsis ruaj khov, xws li martensite, thoob plaws hauv lossis rau ib qho kev sib txawv ntawm ntu ntu.
8. Quenching: Thaum tshav kub kub lub quenched workpiece mus rau ib tug haum kub nyob rau hauv lub ntsiab lus tseem ceeb AC1 rau ib lub sij hawm ntawm lub sij hawm, thiab ces quench nws nrog ib txoj kev uas ua tau raws li qhov yuav tsum tau kom tau raws li qhov yuav tsum tau cov qauv thiab kev ua tau zoo ntawm cov txheej txheem kev kho cua sov.
9. Carbonitriding ntawm hlau: Carbonitriding yog cov txheej txheem ntawm ib txhij infiltrating carbon thiab nitrogen rau hauv txheej txheej ntawm hlau. Carbonitriding kuj feem ntau hu ua cyanidation, thiab yog dav siv nyob rau hauv nruab nrab-temperature gas carbonitration thiab low-temperature gas carbonitration (ie, soft gas nitriding). Lub hom phiaj tseem ceeb ntawm nruab nrab kub roj carbonitriding yog los txhim kho hardness, hnav tsis kam thiab qaug zog tsis kam ntawm steel. Tsawg-kub roj carbonitration feem ntau yog nitriding, thiab nws lub hom phiaj tseem ceeb yog los txhim kho cov hnav tsis kam thiab qaug dab peg ntawm cov hlau.
10. quenching thiab tempering: Feem ntau nws yog kev cai hu rau kev kho cua sov uas ua ke nrog quenching thiab tempering ntawm qhov kub siab hu ua quenching thiab tempering kho. Hardening yog dav siv nyob rau hauv ntau yam ntawm cov yam ntxwv tseem ceeb, tshwj xeeb tshaj yog cov txuas rods, bolts, gears, thiab shafts uas ua hauj lwm nyob rau hauv alternating loads. Tom qab quenching thiab tempering kev kho mob, tempered cordite qauv tau txais, thiab nws cov khoom siv kho mob zoo dua li cov qauv cordite zoo tib yam hardness. Nws qhov hardness nyob ntawm qhov kub-kub quenching kub thiab muaj feem xyuam rau quenching stability ntawm cov hlau thiab cov hla-sectional loj ntawm lub workpiece, feem ntau ntawm HB200-350.
11. Brazing: Ib txheej txheem kev kho cua sov uas ob daim ua haujlwm tau rhaub, melted, thiab welded ua ke.
