Cov ntaub ntawv dab tsi xav tau rau kev nqis peev Casting?
Jun 12, 2024| 1, Molten hlau
Lub ntsiab feature ntawm peev casting yog siv tsawg melting point alloys rau casting, thiaj li ua tiav high-precision casting. Molten hlau feem ntau siv tooj liab raws li alloys, aluminium raws alloys, npib tsib xee raws alloys, thiab lwm yam, uas yog yus muaj los ntawm tsawg melting point, zoo fluidity, tsawg coefficient ntawm thermal expansion, thiab siab hardness.
2, Moulded cov ntaub ntawv
Kev nqis peev pwm cov ntaub ntawv yog cov khoom siv los ua cov pwm peev, thiab lawv qhov zoo ncaj qha cuam tshuam rau kev tsim cov peev txheej zoo. Cov khoom siv peev feem ntau suav nrog gypsum, silicate, siv quav ciab, thiab lwm yam. Ntawm lawv, wax pwm yog ib qho ntawm cov khoom siv dav siv hauv kev peev casting, nrog cov yam ntxwv zoo xws li cov ntsiab lus melting tsawg thiab fluidity siab.
3, Txheej txheej
Coatings yog cov ntaub ntawv siv los siv rau saum npoo ntawm peev pwm, thiab lawv lub luag haujlwm tseem ceeb yog los tiv thaiv cov hlau molten los ntawm kev nkag mus rau saum npoo ntawm peev pwm thiab ua rau nws cov tawv tawv. Cov coatings siv feem ntau suav nrog cov xim silicate, persimmon hmoov coatings, graphite coatings, thiab lwm yam. Ntawm lawv, silicate coatings muaj cov yam ntxwv ntawm zoo tsis adhesion thiab kub tsis kam, ua rau lawv ib tug ntawm cov feem ntau siv coatings nyob rau hauv peev casting.
Zuag qhia tag nrho, cov ntaub ntawv raw ntawm peev casting muaj cov yam ntxwv xws li qhov tsis tshua muaj melting point, siab fluidity, thiab qis coefficient ntawm thermal expansion, uas yog ib qho tseem ceeb vim li cas vim li cas peev casting tuaj yeem ua tiav high-precision casting. Tsis tas li ntawd, qhov zoo ntawm cov ntaub ntawv peev thiab txheej txheej hauv peev casting yog ncaj qha ntsig txog qhov zoo thiab kev tsim cov khoom tiav. Yog li ntawd, kev xaiv cov ntaub ntawv thiab txheej txheej yog ib qho tseem ceeb heev nyob rau hauv lub peev casting txheej txheem.
