Cov Txheej Txheem Txheej Txheem
Txiav:S690QL daim hlau tuaj yeem txiav siv cov thev naus laus zis zoo li CNC ntshav, laser, lossis oxy- roj. Rau thermal txiav, nws raug nquahu kom khaws cov khoom tsawg kawg ntawm chav tsev kub kom tsis txhob muaj teeb meem.
Bending thiab forming:
Cold forming: Possible with powerful equipment. Recommended inside bend radii are typically >4×thickness for longitudinal and >3 × thickness rau transverse cov lus qhia.
Kub txoj kev:Feem ntau zam dhau 580℃-600 degreevim nws tuaj yeem hloov lub xeev tempered thiab degrade mechanical zog. Yog hais tias rhuab saum toj no ntau yam, cov khoom yuav tsum tau mus rau ib tug tshiab quenching thiab tempering txheej txheem.
Vuam:S690QL muaj qhov zoo weldability tab sis rhiab rau cov cua txias.
Txoj kev:MIG/MAG thiab TIG feem ntau siv.
Cov kev ceev faj:Ua ntej- cua sov feem ntau yuav tsum tau zam kom tsis txhob tawg. Filler hlau yuav tsum muaj lub zog zoo sib xws los yog me ntsis qis dua lub hauv paus hlau.
Machining:Rau drilling, cobalt- alloyed siab- ceev steels (HSSCO) raug pom zoo nrog txiav ceev ntawm 17-19 m / min.
Kev ua haujlwm ntau lawm
Kev tsim khoom lag luam ntawm S690QL suav nrog kev ua ntu zus kom ntseeg tau tias nws cov khoom muaj zog - siab:
Refining & Casting:Converter refining ua raws li kev nruam casting.
Rolling:Tswj dov thiab txias kom ua tiav cov qauv phaj pib.
Kev kho cua sov (Q + T):Cov kauj ruam txhais qhov twg lub phaj yog quenched(sai txias nyob rau hauv dej los ntawm saum toj no nws tseem ceeb kub) kom harden nws, ua raws li los ntawmtempering(re- cua sov kom qis dua qhov tseem ceeb) kom rov ua kom tawv thiab ductility.
Ua tiav:Straightening, soj ntsuam saum npoo, thiab ultrasonic flaw detection.
Cov ntawv thov tseem ceeb
Nws cov ntawv thov nthuav dav ntau yam hnyav- kev lag luam, feem ntau suav nrog:
Kev tsim kho kev lag luam: Siv dav hauv cov qauv loj - nplais xws li kev txhawb nqa choj, crane booms, thiab siab - nce lub tsev, qhov siab load- bearing peev thiab lub teeb yuag yog qhov tseem ceeb.
Automotive thiab kev thauj mus los sector: Siv rau cov tsheb thav duab, cov khoom siv trailer, thiab cov khoom siv tsheb ciav hlau, nws txhim kho cov khoom ruaj khov thaum txo qhov hnyav tag nrho los txhim kho roj efficiency.
Offshore thiab mining teb: Qhov tseem ceeb rau offshore platforms thiab mining machinery Cheebtsam, raws li nws muaj peev xwm tiv taus ib puag ncig hnyav xws li corrosion thiab tsis kub.
