Q: Dab tsi vuam hlau / electrode pom zoo rau vuam Q355D steel daim hlau?
A: Rau phau ntawv arc vuam, siv E50 series electrodes (E5015, E5016); rau roj shielded vuam, siv ER50-6 vuam hlau; rau submerged arc vuam, siv H08MnA vuam hlau nrog HJ431 flux.
Q: Puas yog Q355D xav tau kev kho cua sov tom qab vuam?
A: Raws li kev vuam tsis tas yuav tsum tau kho cua sov. Txawm li cas los xij, rau cov phaj tuab nrog ntau txheej txheej, cov txheej txheem welded nrog cov rigidity siab, los yog cov uas yuav tsum tau qis - kub ua hauj lwm tom qab vuam, kev nyuaj siab -relieving annealing (550 ~ 650 degree) yog pom zoo.
Q: Q355D puas tuaj yeem raug quenching, tempering, lossis lwm yam kev kho cua sov?
A: Yog, nws tuaj yeem ua kom sov- kho. Kev kho cua sov ntxiv txhim kho lub zog thiab lub zog, nrog lub zog tawm los mus txog 450MPa thiab zoo dua qis - qhov kub thiab txias ua haujlwm. Kev cai-ua kom sov- kho steel phaj yuav tsum tau.
Q: Dab tsi yog daim ntawv thov tseem ceeb ntawm Q355D steel daim hlau?
A: Cov ntawv thov tseem ceeb yog cov qauv hlau siv nyob rau hauv qis- qhov kub thiab txias, xws li cua turbine yees, cryogenic siab hlab ntsha, kev tsim tshuab (excavators / cranes nyob rau hauv cheeb tsam txias), txuas hniav (sab qaum teb cheeb tsam), nkoj decks, thiab steel qauv rhiav (siab{1}} cheeb tsam latitude).
Q: Daim ntawv thov scenarios ntawm Q355D thiab Q355E txawv li cas?
A: Q355D yog tsim rau qis- qhov kub thiab txias ib puag ncig ntawm -20 degree, thaum Q355E haum rau ultra- qis- qhov kub thiab txias ib puag ncig ntawm -40℃. Yog tias qhov kub ntawm lub caij ntuj no qis tshaj plaws hauv qhov project qhov chaw siab dua lossis sib npaug ntawm -20 degree, xaiv qib D; Yog tias tsawg dua lossis sib npaug ntawm -40 degree, xaiv qib E; yog tias nws poob ntawm ob, qib D yuav tsum tau ua ntej (kom tau txais txiaj ntsig zoo dua).
