Waa maxay faa'iidada tallaalka beera-engeeg, waayo castings dhinta aluminium?
Eeg si faahfaahsan by soo socda:
1, toogteen engeeg uu leeyahay wax soo saarka sare
Natiijada isticmaalka nooc cusub oo shot engeeg mashiinka in 110 ~ 260 kg / min ee mugga-engeeg ah, engeeg xawaaraha of 50 ~ 75 m / s gano engeeg gabal shaqada, in dhowr daqiiqo si uu u dhameystiro ku nadiif-up. Waayo, size waaweyn ama ka weyn waslad shaqada waxaa loo isticmaali karaa shot badan qalab-engeeg waqti isku mid ah.
2, dusha sare ee qaybaha si aad u nadiifiso ilaa, by midabka, saamayn madaxtooyada
daaweynta shot engeeg ka dib, ka saari kara lifaaqa ah ee dusha gabal shaqada, ku laayeen oo khafiif ah, Oo baalashiisa u duulaya, Wasaqda, la baabi'iyo xagashada, si gabal shaqada bandhigeysa dabeecadda aasaasiga ah.
3, in la baabi'iyo ka fiirsashada stress dusha
Qaybo ee geedi socodka qaboojinta, ay sabab u dhumucda derbiga sinnayn, heerka qaboojinta waa khilaafsan, taasoo keentay in fiirsashada stress dusha. Ka dib-engeeg tallaalka, hagaajin kartaa qaab-dhismeedka dusha sare, si loo baabi'iyo fiirsashada stress dusha (stress siligga), loo hagaajiyo xoog daal, iyo koror yar darantahay ingeega, dusha sare.
4, kordhin quruxda dusha
Sida laga gano waa shot kubada, saadaalineysa in gabal shaqada si loo soo saaro godka yar concave ee, wuxuu ahaa spherical, sida muraayad concave, in irradiation iftiin, sida xiddigaha biligleynaya, waa farxin isha.
5, si loo hagaajiyo Amda daahan dusha sare
ka dib engeeg tallaalka, roughness waxay gaadhi kartaa Ra1.6 ~ 6.3μm, bedka waxaa si weyn u kordhay, iyo wasakh dusha sare la tirtiro. Sidaa darteed, Amda ee dusha sare waxaa si wayn u xoojinaya marka dusha sare waxaa la rinjiyeeyay ama wax kale.
6, geeddi-socodka waa mid fudud, kaydka maalgashiga
Natiijada engeeg shot qalalan, iyo qalabaysan nidaamka ka saarida ciidda, sidaas ka dib markii engeeg tallaalka loo gudbin karaa habka soo socda, baabi'inta baahida loo qabo sandblasting dareere ah iyo qalabka lagu qalajiyo loo baahan yahay.
