Kuv yuav tsis hnov qab lub suab hnyav - lub luag haujlwm conveyor roller ncej snapping hauv tus neeg siv khoom cov khoom ua tiav. Nws suab zoo li ib rab phom tua.
Tus saib xyuas kev saib xyuas tau npau taws heev. Nws taw tes rau ntawm qhov tawg ntawm S45C seamless steel yeeb nkab uas peb tau muab. "Koj cov hlau yog nkig!" nws qw. "Peb welded lub mounting flanges rau hauv cov yeeb nkab, muab tso rau hauv kev pab cuam, thiab nws tawg nyob rau hauv txoj cai weld kab tom qab peb hnub!"
Kuv khaws lub flange tawg thiab ntsia ntawm qhov vuam. "Koj cov txiv neej puas preheat cov yeeb nkab ua ntej vuam?" kuv nug.
Nws ntsia kuv zoo li kuv hais lus txawv teb chaws. "Preheat? Nws tsuas yog cov yeeb nkab steel xwb. Peb nyuam qhuav tso cov hlaws dai."
Tom qab ntau tshaj li kaum xyoo ntawm kev muab thiab teeb meem kev kho tshuab hlau tubing ntawm Boton Industrial Supply Co., Ltd., Kuv tuaj yeem qhia koj tias qhov xwm txheej no tshwm sim thoob plaws ntiaj teb. Cov kws tsim khoom thiab cov kws tsim khoom pom tias S45C yog cov khoom muaj zog, hwm zoo, yog li lawv kho nws raws nraim li lawv xav tau cov hlau me me.
Tab sis S45C tsis yog hlau me me. Nws yog nruab nrab - carbon powerhouse. Yog tias koj tsis nkag siab nws "tus cwj pwm", nws yuav ua rau koj cov cuab yeej ua haujlwm puas lossis tawg koj cov welds. Cia peb txiav los ntawm JIS specification PDFs thiab saib seb S45C seamless steel yeeb nkab yog dab tsi, thiab yuav siv nws li cas tsis tua koj tus kheej hauv ko taw.
Dab tsi yog S45C?
S45C yog qib carbon structural steel txhais los ntawm Japanese Industrial Standard (JIS G4051 rau tshuab qauv zoo).
S stands rau Steel.
45 txhais tau tias cov ntsiab lus carbon yog kwv yees li 0.45%.
C sawv cev rau Carbon.
Kev txhais lus thoob ntiaj teb: Yog tias koj tab tom yuav los ntawm peb ntawm Boton, koj yuav tsum paub tias S45C yog tib yam tsiaj nyaum zoo ib yam li 1045 hauv Asmeskas, C45 hauv Tebchaws Europe (EN / DIN), thiab 45 # hauv Suav teb (GB). Thaum koj xaj S45C seamless yeeb nkab los ntawm peb, koj tau txais kev lees paub thoob ntiaj teb nruab nrab - cov qauv carbon.
Cov Txheej Txheem: Nws txhais li cas ntawm lub tshuab dhos
Cia peb hla cov ntxhuav tshuaj qhuav thiab tham txog cov ntsiab lus no ua li cas thaum CNC tshuab dhos tau qhib.
Cov pa roj carbon (~0.42% - 0.50%): Qhov no yog cov leeg. Tsis zoo li qis- carbon steels uas "gummy" thiab qhwv ib ncig ntawm koj cov cuab yeej txiav, cov pa roj carbon ntau dua hauv S45C ua rau cov chips tawg kom huv. Nws tshuab zoo nkauj, muab koj lub ntsej muag zoo kawg nkaus thiab lub neej ntev lub cuab yeej. Qhov tseem ceeb tshaj, cov pa roj carbon qib no tso cai rau cov hlau ua kom sov- kho (quenched thiab tempered) kom ua tiav qhov tawv tawv loj heev.
Manganese (~ 0.60% - 0.90}%): Qhov no ntxiv qhov tob rau cov txheej txheem hardening (hardenability) thiab muab cov tub ntxhais ntawm cov yeeb nkab toughness yog li nws tsis snap nyob rau hauv hnyav shock loads.
"Brittle" Trap: Weldability yog tus Dealbreaker
Qhov no coj peb rov qab mus rau qhov tawg conveyor ncej.
Vim tias S45C muaj cov ntsiab lus carbon siab, nws muaj "hardenability." Thaum koj siv qhov khaus, thaj chaw kub ntawm qhov vuam arc mus rau S45C, thiab tom qab ntawd cia nws txias rau hauv lub khw muag khoom huab cua, Cov Cuab Yeej Cuab Yeej -Tebchaws cuam tshuam (HAZ) txias sai heev uas nws tsim martensite. Martensite yog ib qho nyuaj heev, tab sis nws yog iav. Nws muaj xoom ductility. Thaum lub sij hawm lub ncej siv lub dynamic load, nws tawg ntawm lub weld.
Txoj Cai Boton Field: Yog tias koj yuav vuam S45C seamless yeeb nkab, koj yuav tsum preheat qhov sib koom ua ke kom tsawg kawg yog 200℃- 300℃(400℃F - 570}℃F) ua ntej welding, siv qis - hydrogen electrodes, thiab qhov zoo tshaj, ua ib qho post-weld stress relief. Yog tias koj lub khw tsis muaj cov khoom siv thermal ua qhov no, tsis txhob siv S45C rau cov khoom sib dhos. Hloov mus rau S20C lossis S25C.
Qhov twg S45C Seamless yeeb nkab tiag tiag ci
Yog tias koj hwm nws cov kev txwv vuam, S45C yog cov khoom siv tsis txaus ntseeg. Vim li cas siv nws rau hauv cov yeeb nkab / raj daim ntawv es tsis txhob siv cov khoom siv? Qhov hnyav txuag thiab kev siv sab hauv. Nov yog qhov peb xa cov yeeb nkab S45C tshaj plaws:
1. Hydraulic Lub tog raj kheej raj
S45C yog tus qauv kev lag luam rau hnyav -lub tog raj kheej hydraulic. Peb muab nws nyob rau hauv honed los yog skived-thiab-roller-burnished (SRB) tej yam kev mob. Lub zog yield zog ntawm S45C tso cai rau lub tog raj kheej los tuav 3000+ PSI sab hauv siab yam tsis muaj ballooning, thaum huv si, suav nrog -dawb seamless sab hauv muab ib daim iav tiav rau piston seals.
2. Hollow Drive Shafts thiab Rollers
Hauv cov tshuab hnyav, cov ncej khoom hnyav hnyav heev. Los ntawm kev siv cov tuab -walled S45C seamless yeeb nkab, engineers muaj peev xwm tuav tau tib yam sab nraud txoj kab uas hla thiab dabtsi yog khoov lub zog raws li ib tug khoom bar, tab sis txiav lub luj los ntawm 30-40%. Peb feem ntau muab cov kav dej no ua ntej-machined thiab tom qab ntawd induction-hardened sab nraud rau kev hnav tsis kam.
3. Gears thiab Sprockets
Rau qhov loj, hnyav - lub luag haujlwm gears, machining ib qho khoom thaiv ntawm steel yog nkim sijhawm thiab khoom siv. Fabricators yuav tuab- cov yeeb nkab S45C phab ntsa, txiav lub nplhaib, tshuab cov hniav iav ntawm OD, thiab cua sov- kho nws. Qhov tshwm sim yog siab - lub zog iav nrog ib feem ntawm lub sij hawm machining.
Tsis txhob kwv yees, Pib Engineering
S45C seamless steel yeeb nkab yog cov hwm zoo, siab - cov khoom muaj zog uas tuaj yeem ua lossis tawg koj cov khoom siv tshuab. Nws tshuab zoo li npau suav thiab siv cua sov- kho kom zoo nkauj, tab sis nws yuav rau txim rau koj yog tias koj sim ua kom nws txias.

FAQ
Q: US lossis European sib npaug ntawm JIS S45C seamless steel yeeb nkab yog dab tsi?
A: S45C yog ncaj qha sib npaug rau 1045 hauv Asmeskas, C45 hauv Europe, thiab 45 # hlau hauv Suav teb. Lawv qhia tib yam ~ 0.45% cov ntsiab lus carbon thiab cov khoom siv kho tshuab.
Q: Kuv puas tuaj yeem txuas S45C seamless steel yeeb nkab?
A: Yog, tab sis nws yuav tsum tau ceev faj nruj. Vim tias nws yog ib qho nruab nrab - carbon steel, nws yog qhov ua rau txias tawg hauv tshav kub - thaj tsam cuam tshuam. Koj yuav tsum preheat cov yeeb nkab rau 200℃-300℃ua ntej welding, siv tsawg-hydrogen consumables, thiab ua post-weld heat treatment. Yog tias koj tsis tuaj yeem ua kom sov, siv qhov qis -carbon lwm yam xws li S20C.
Q: Vim li cas siv S45C seamless yeeb nkab es tsis txhob ntawm cov khoom puag ncig rau shafts?
A: Siv S45C seamless yeeb nkab rau hollow shafts ho txo qhov hnyav tag nrho ntawm cov khoom thaum tuav tib txoj kab uas hla thiab siab torsional / dabtsi yog khoov lub zog. Nws tseem yog tus nqi ntau dua - ua haujlwm tau zoo thiab nrawm dua rau lub tshuab dua li tshem tawm cov khoom loj ntawm cov khoom siv.
