1. Quenching: Tom qab qhov chaw tau rhaub mus rau qhov ntsuas kub hauv qhov kev ntsuas kub kho lub txim, cov seem tau khaws cia rau qee lub sijhawm, thiab tom qab ntawd txias rau hauv cov xov xwm sib txawv raws li qhov yuav tsum ua, thiaj li ua kom qhov nyuaj ntawm qhov seem.
2. Kev Carburizing: Cov seem tau muab tso rau hauv kev kho cua sov tsim kev rau txim kom tau txais qhov kub thiab txias rau qee lub sijhawm thiab khaws cia rau qee lub sijhawm, thiab tom qab ntawd cov pa roj carbon cov khoom nruab nrab tau nkag los nkag rau cov pa roj carbon mus rau qhov pom ntawm seem kom txhim kho hardness thiab hnav tsis kam ntawm cov saw.
3. Kev Ua Kub Taub: Tom qab quenching, qhov seem tom qab quenching yog rhuab ntawm qhov ntsuas kub hauv qhov tsim kho cua sov, thiab qhov kub tau muab cia rau qee lub sijhawm thiab tom qab ntawd txias. Lub siab txias ntawm qhov chaw tuaj yeem txo qhov quenching hardness, tshem tawm cov kev ntxhov siab quenching thiab txhim kho qhov nro.
4, blackening: txais txoj ntsiab cai ntawm polymer organic polymerization, siv kev kho kub kom tsim txom cov txheej txheem ntawm tempering residual tshav kub hauv cov txheej txheem ntawm cov yeeb yaj kiab dub. Tom qab blackening, lub workpiece muaj lub teeb, corrosion tsis kam thiab muaj zog xeb kuj; kev siv dag zog tsawg thiab kev tsim khoom lag luam ib puag ncig.
5, txhaj koob tshuaj tivthaiv peening: ib hom kev kho kom zoo nkauj, raws li qhov yuav tsum tau txais qee qhov txoj kab uas hla ntawm cov hlau tau txau rau qhov pom ntawm seem, ua rau lub qhov taub kom zoo me me los txhim kho cov ntsej muag.
6. Xiav: Tom qab cov cua sov ntawm cov ntu mus rau qhov kub thiab txias, cov tshuaj aqueous tov yog txias thiab saponified, kom pom cov xim ntawm cov seem pom xiav. Qhov saum npoo ntawm cov saw uas tau kho nrog xiav thiab xiav yog elegant thiab muaj xeb-siv cov nyhuv. Dab tsi tsis txaus yog tias cov kuab tshuaj aqueous no ua rau muaj kuab paug ntau rau ib puag ncig.
7. Phosphating: Qhov feem yog muab tso rau hauv cov tshuaj phosphating ntawm qhov ntsuas kub kom tsim ib txheej phosphating nyob rau sab nraud ntawm ntu, uas tuaj yeem ua rau lub ntsej muag pom qhov dub lossis txho, thiab txhim kho txoj saw thiab ua tiav lub hom phiaj anti-corrosion. Cov kev daws teeb meem no yog rov siv dua tshiab thiab tsis muaj kuab paug rau cov ib puag ncig.
8. Galvanizing: Tus qauv ntawm kev lees txais electroplating lossis electroless galvanizing ua rau txheej galvanized nyob sab nraud ntawm ib sab. Galvanized txheej yuav ua tau ob qho tib si elegant thiab anti-xeb. Galvanized saw yog qhov tshwm sim xws li qhib qhov chaw.
9. Nickel plating: Cov txheej txheem ntawm kev lees txais electroplating lossis electroless nickel plating, tsim cov txheej txheem nickel plated rau sab nrauv ntawm sab nrauv, cov npib tsib xee plated txheej yuav ua tau ob qho muaj kuab thiab tiv thaiv xeb. Nickel-plated chains yog siv dav hauv cov chaw qhib.
10. Oiling: Tom qab cov roj tau thauj mus los, cov saw yuav xeb thiab ntau dua.
