1. Qhov sib txawv steel muaj pes tsawg leeg
- Chrome-plated bearing steel rods: qhov sib xws ntawm cov tshuaj muaj pes tsawg leeg ntawm cov kabmob steel, cov ntsiab lus thiab kev faib tawm ntawm cov khoom tsis yog xim hlau, thiab kev faib tawm ntawm carbides yog nruj heev.Nws yog ib qho ntawm cov qib steel nruj tshaj plaws nyob rau hauv tag nrho cov hlau ntau lawm.
- CK45 steel chrome-plated pas nrig: Nws yog cov khoom siv zoo carbon steel, sib haum rau Japanese tus qauv S45C, Asmeskas tus qauv: 1045, thiab German tus qauv C45.Nws cov yam ntxwv yog tias nws muaj zog dua thiab ua haujlwm rau deformation dua li qub A3 steel.
2. Cov khoom siv sib txawv
- Cov kabmob steel chromium-plated pas nrig: Feem ntau siv GB / T18254-2002 tus qauv thiab Laiwu Steel GCr15JD daim ntawv cog lus zoo yoog raws qhov yuav tsum tau ua ntawm precision forged bearing cov neeg siv. Cov kev xav tau zoo ntawmGCr15JDKev pom zoo yog nruj dua li GB / T18254-2002 tus qauv, thiab GCr15JD yuav tsum muaj cov ntsiab lus oxygen ≤10ppm, theem nruab nrab ntawm kev sib cais yog tsawg dua los yog sib npaug rau 1.0, kev tswj muaj pes tsawg leeg, qhov ntev thiab qhov sib txawv ntawm qhov sib txawv yog nruj dua li GB / T18254- 2002 standard.
- CK45 steel chrome-plated bar: Qhov kev pom zoo kho cua sov rau CK45 steel tau teev nyob rau hauv GB / T699-1999 tus qauv yog 850 ℃ normalizing, 840 ℃ quenching, thiab 600 ℃ tempering.Qhov kev ua tau zoo yog tias lub zog tawm los yog ≥355MPa.
3.Txoj kev sib txawv
- Cov kabmob steel chromium-plated pas nrig: 50 tons thiab siab dua UHP hluav taws xob rauv smelting 60 tons thiab siab dua LF rauv refining 60 tons thiab siab dua VD rauv nqus tsev kho mob, alloy steel billet los yog daim duab plaub nruam casting (260mm × 300mm, 180mm × 220mm), qeeb txias los yog Kev Tshawb Fawb Txog Kev Tshawb Fawb thiab khaws cov khoom kub dov dov.
- CK45 steel chromium-plated pas nrig: 40Cr / 5140 steel yuav tsum tau roj-txias tom qab quenching.40Cr / 5140 steel muaj qhov zoo hardenability, thiab tuaj yeem hardened thaum txias hauv roj, thiab deformation thiab cracking nyiam ntawm workpiece me me.Txawm li cas los xij, nyob rau hauv cov xwm txheej ntawm cov khoom siv roj nruj, cov lag luam me tuaj yeem tua cov khoom ua haujlwm nrog cov duab tsis yooj yim hauv dej, thiab tsis pom muaj kab nrib pleb, tab sis tus neeg teb xov tooj yuav tsum nruj me ntsis tswj qhov kub ntawm cov dej nkag thiab qhov hluav taws xob raws li kev paub dhau los.
