Chromium Additive Rau Aluminium Alloy Casting

2. Siv cov teeb meem:

2.1 Ntxiv qhov kub thiab txias: ≥730 ° C.

2.2 Kev siv ntau npaum li cas ntawm cov khoom no yog xam raws li cov qauv hauv qab no:

Nco tseg: Vim qhov sib txawv ntawm cov neeg siv khoom thiab metallurgical tej yam kev mob nyob rau hauv lub cub tawg, qhov tseeb ntxiv yuav tsum tau muab xam thiab txiav txim raws li cov ntaub ntawv xeem ua ntej lubrauv.

2.3 Ntxiv txoj kev:

Tom qab melting nyob rau hauv lub cub tawg, do tusyees, coj ib tug qauv thiab soj ntsuam los xam tus nqi ntawm chromium tus neeg sawv cev ntxiv.Thaum lub melting kub mus txog, tshem tawm cov dross rau saum npoo ntawm cov yaj, thiab disperse cov khoom mus rau ntau qhov chaw ntawm lub pas dej ua ke (yog hais tias nws yog tsim nyog los ntxiv manganese thiab tooj liab, lawv yuav muab ntxiv rau tib lub sij hawm).Tom qab cov tshuaj tiv thaiv tiav, sawv ntsug rau10-20 feeb, ces tag nrhodo rau 5 feeb;sawv tseem rov raulwm 5-10 feeb, thiab coj ib qho qauv rau kev tsom xam;Tsuas yog cov khoom xyaw tsim nyog ces nws tuaj yeem hloov mus rau cov txheej txheem tom ntej.

3. Ntim thiab cia:

Cov khoom no yog ib puag ncigncuav mog qab zibtsaus grey pob, lub ntim sab hauv yog lub hnab yas / lub hnab nqus tsev / aluminium ntawv ci ntim;cov khoom ntim sab nrauv yog lub thawv ntawv;250g / pcs, 1kg / hnab, 20kg / thawv.Khaws rau hauv qhov chaw ventilated thiab qhuav, deb ntawm noo noo.

4. Lub neej txee

Yim lub hlis, tuaj yeem siv ncaj qha tom qab qhib lub thawv.
