Nickel additive rau aluminium alloy casting

Cov lus qhia rau kev siv:

1. Cov qauv hauv qab no:

Nco tseg: Vim yog qhov sib txawv ntawm metallurgical tej yam kev mob ntawm cov neeg siv thiabrauv, qhov tseeb tawm los thiab qhov nyiaj ntxiv yuav tsum tau muab xam thiab txiav txim siab raws li cov ntaub ntawv xeem ua ntej lub cub tawg.

2. Ntxiv txoj kev:

Ntxiv txoj kev: Tom qab tus nqi yog melted, do tusyees, coj ib tug qauv thiab soj ntsuam los xam tus nqi ntawm cov nickel tus neeg sawv cev ntxiv.Thaum qhov kub ntawm lub yaj mus txog, tshem tawm cov dross ntawm lub yaj, thiab ces disperse cov khoom mus rau hauv.ntau qhov chawntawm lub pas dej ua ke.
Sawv ntsug rau 20-30 feeb, tag nrho do rau 5 feeb, thiab tom qab ntawd sawv ntsug rau 10-20 feeb kom txog thaum lub melting tiav, coj mus kuaj rau kev soj ntsuam, thiab hloov mus rau cov txheej txheem tom ntej yog tias cov khoom xyaw tsim nyog.

3. Ntxiv qhov kub thiab txias:≥730 ℃

4.Package cia:

Cov khoom no yog tsaus grey puag ncig lub ncuav mog qab zib zoo li cov khoom, lub ntim sab hauv yog cov ntawv pov thawj noo noo thiab cov hnab yas ntim khoom,250g / pcs, 1kg / hnab, 20kg / thawv.Khaws rau hauv qhov chaw cua thiab qhuav, kom deb ntawm cov dej noo, vim tias cov hmoov hlau uas muaj nyob rau hauv cov additive yog heev nquag thiab yooj yim rau oxidize, cov flux muaj nyob rau hauv cov additive susceptible mus ya raws, qhov saum npoo ntawm additive yog oxidized tom qab damp, thiab nyob rau hauv lub ventilated qhov chaw. mob hnyav, yuav muaj pulverization, yog li cuam tshuam rau qhov tseeb tawm los, lossis txawm tias poob.

5.Lub txee lub neej yog 8 lub hlis, npaj siv tawm ntawm lub thawv.
