Hauv kev lag luam niaj hnub kev lag luam, kev ua haujlwm ntawm cov hlau ncaj qha cuam tshuam rau qhov zoo thiab kev ua haujlwm ntawm cov khoom. Raws li kev ua haujlwm siab dawb-txiav cov qauv hlau, 12L14 steel phaj tau dhau los ua qhov kev xaiv zoo tshaj plaws rau cov tshuab precision, cov khoom siv tsheb, cov khoom siv hluav taws xob thiab lwm yam lag luam nrog nws cov tshuaj lom neeg tshwj xeeb thiab cov yam ntxwv ua haujlwm zoo.
1. Tshuaj muaj pes tsawg leeg: lub hauv paus ntawm kev ua tau zoo heev
Qhov tshwj xeeb kev ua tau zoo ntawm 12L14 steel phaj los ntawm nws ua tib zoo tsim tshuaj muaj pes tsawg leeg. Cov ntsiab lus carbon yog nruj me ntsis tswj ntawm ≤0.15%, uas ua kom lub toughness thiab ductility ntawm cov khoom; cov ntsiab lus manganese ntau dua (0.85 - 1.15%) txhim kho lub zog thiab hnav tsis kam; thiab cov ntsiab lus silicon yog ≤0.10%, uas txo qhov cuam tshuam ntawm impurities ntawm kev ua haujlwm. Tsis tas li ntawd, qhov sib ntxiv ntawm phosphorus (0.04 - 0.09%) thiab sulfur (0.26 - 0.35%) ua rau txhim kho kev ua tau zoo; qhov sib ntxiv ntawm cov hlau lead (0.15 - 0.35%) ntxiv txo qhov kev tiv thaiv kev txiav, ua rau cov chips yooj yim tawg, thiab txhim kho kev ua haujlwm zoo thiab lub neej cuab yeej.
II. Qhov zoo ntawm kev ua tau zoo: suav nrog kev ua haujlwm thiab kev siv
1. Kev ua tau zoo ntawm kev txiav: 12L14 steel phaj tuaj yeem hu ua "tus phooj ywg tus khub rau kev siv tshuab". Nws txiav tsis kam yog ntau tshaj 30% qis dua li cov hlau zoo tib yam. Nws tuaj yeem ua tiav high-speed txiav thiab loj pub ua. Nws ua tau zoo ntawm cov tshuab dhos tsis siv neeg, CNC tshuab cuab yeej thiab lwm yam khoom siv, ua kom lub voj voog ua tiav thiab txo cov nqi tsim khoom.
2. Zoo nto zoo: Lub nto tiav ntawm cov txheej txheem 12L14 steel phaj tuaj yeem ncav cuag Ra0.8-1.6μm. Tsis muaj teeb meem tom qab polishing kev kho mob yuav tsum tau. Electroplating, txau thiab lwm yam txheej txheem kho saum npoo tuaj yeem nqa ncaj qha, uas tsis yog tsuas yog ua kom cov khoom zoo nkauj, tab sis kuj txhim kho kev tsim khoom.
3. Cov khoom siv ruaj khov: Lub zog tensile ntawm cov phaj hlau yog nyob rau hauv thaj tsam ntawm 380-460MPa, qhov elongation yog 20-40%, qhov sib txawv ntawm qhov shrinkage yog 35-60%, thiab lub hardness yog nruab nrab (kub-kub-kuav los tiag lub xeev 121HB, txias dov lub xeev 163HB). Nws tuaj yeem tswj xyuas cov khoom siv kho tshuab ruaj khov nyob rau hauv ntau yam kev ua haujlwm thiab ua tau raws li kev xav tau ntawm cov xwm txheej sib txawv.
4. Kev tiv thaiv ib puag ncig thiab kev nyab xeeb: 12L14 steel phaj nruj me ntsis raws li thoob ntiaj teb cov qauv kev tiv thaiv ib puag ncig, tau dhau EU SGS daim ntawv pov thawj ib puag ncig thiab Swiss ib puag ncig certification, tsis muaj cov khoom phom sij xws li txhuas thiab mercury, thiab yog nyob rau hauv txoj kab nrog txoj kev loj hlob ntawm kev tsim ntsuab niaj hnub.
III. Specifications thiab cov qauv: Kho kom haum rau ntau yam kev xav tau
12L14 steel phaj muaj ntau yam siv tau hauv cov lus qhia tshwj xeeb. Lub thickness ntau yam ntawm kub dov steel phaj yog 1-180mm, lub thickness ntawm txias-kuav los tiag steel phaj yog 0.1-4.0mm, cov pa dav dav yog 1220mm, thiab qhov ntev yog 2440mm, uas tuaj yeem hloov kho raws li cov neeg siv khoom xav tau. Hais txog cov qauv, nws raug raws li cov qauv thoob ntiaj teb xws li AISI 12L14 hauv Tebchaws Meskas, SUM24L hauv JIS G4804 hauv Nyij Pooj, thiab 10SPb20 (1.0722) hauv DIN EN 10087 hauv Tebchaws Yelemees, kom ntseeg tau tias muaj ntau yam thiab sib hloov ntawm cov khoom lag luam hauv ntiaj teb.
IV. Daim ntawv thov teb: Txhawb kev txhim kho kev lag luam
1. Automotive manufacturing: siv los tsim precision qhov chaw xws li gearbox gear shafts, roj injector vaj tse, sensor brackets, thiab lwm yam., los xyuas kom meej lub efficiency ntawm lub tsheb fais fab system thiab hluav taws xob tswj systems.
2. Electronics thiab precision instruments: Nws yog cov khoom siv rau kev tsim cov khoom siv high-precision xws li saib iav, cov cuab yeej kho mob phais, thiab cov cuab yeej kho qhov muag kho qhov muag, pab cov khoom siv hluav taws xob thiab cov cuab yeej precision kom ua tiav cov miniaturization thiab siab precision.
3. Mechanical manufacturing: Nws plays lub luag haujlwm tseem ceeb hauv kev tsim cov khoom xws li hydraulic valve cores, bearing retainers, thiab txuas pins ntawm cov khoom siv automation, thiab txhim kho kev ruaj ntseg thiab durability ntawm cov cuab yeej siv tshuab.
