Cov Txheej Txheem Ntau Lawm thiab Kev Tswj Xyuas Zoo Ntawm S355jr UB 406x178x74 H Tshooj Hlau
Smelting thiab dov: smelting los ntawm hluav taws xob tshuab hluav taws lossis hloov kho hluav taws xob, ib qho kev xav tau ua ib qho kev kho mob ib txwm ua rau cov nplej ua kom zoo thiab txhim kho kev ua haujlwm; Qhov saum npoo yog polished thiab xeb-tshem tawm kom txhim kho corrosion tsis kam.
Precision Kev Ua: Cov khoom siv tau siv tau siv los ua kom ntseeg tau tias qhov xav tau kev zam txim siab ua tau raws li cov txuas hniav theem siab ntawm cov choj, vaj tse thiab lwm yam haujlwm.
Daim Ntawv Thov Kev Ua Si ntawm S355JR UB 406x178x74 H Zoo Li Tus Hlau
Kev thiab choj cenporessering: Siv cov kab teeb tseem dav, choj Pieve, thiab kev txhawb nqa qauv. Nws lub zog siab thiab tawv muaj peev xwm tiv taus cov khoom siv zuj zus.
Cov xwm txheej raug: Cov qauv tseem ceeb ntawm cov choj coob, txoj kev loj ntawm kev hla.
Kev tsim kho teb: high thav ntawv, nroj tsuag nroj tsuag.
Lub nkoj nkoj: Hull cov qauv, lawj.
Kev tsim machinery: siv rau load-cov kabmob cov khoom xws li cov khoom siv hauv tsev thiab cov nkhaus.
