Hauj lwm lawm

JQ·YJ501-1A yog titanium oxide hom ultra-low-hydrogen CO₂gas shielded flux-cored vuam hlau, thiab diffusion hydrogen ntsiab lus ntawm deposited hlau yog qis dua 5ml / 100g. Nws muaj kev ua haujlwm zoo heev nrog cov mos mos thiab du arc, qib qis spatter, tsis muaj peev xwm tshem tawm slag thiab pom cov hlaws zoo nkauj. Nws raug tso cai rau txhua txoj haujlwm vuam. Lub vuam efficiency yog siab. Cov hlau deposited yog toughened los ntawm cov ntsiab lus, uas muaj zoo heev tsis tshua muaj kub toughness thiab zoo tawg kuj.

Lub hom phiaj

Cov khoom muaj feem xyuam rau vuam cov qauv hlau nrog tensile lub zog ntawm 490MPa, feem ntau siv nyob rau hauv lub teb xws li nkoj, txuas hniav, siv machinery, marine engineering, thee mining machinery, siv machinery thiab thiaj li nyob.

Tshuaj muaj pes tsawg leeg ntawm deposited hlau (%) (shielding gas: CO₂)

Cov kev ceev faj

1. Lub workpiece yuav tsum tau degreased thiab derusted ua ntej vuam.
2. Thaum vuam, cov roj ntws feem ntau yog 20-25L / min.
3. Thaum vuam flux-cored vuam hlau, qhov ntev txuas ntxiv yuav tsum yog 15-25 hli.
4. Cov av noo ntawm vuam hlau warehouse yuav tsum tau khaws cia hauv qab 60%.
5. Lub vuam hlau tsis muaj lub tshuab nqus tsev yuav tsum tsis txhob muab khaws cia rau ntau tshaj ib nrab xyoo thiab vuam hlau nrog lub tshuab nqus tsev yuav tsum tsis txhob muab khaws cia rau ntau tshaj ib xyoos.
