Zvakanakira zve Ndaona pombi yesimbi
Inogona kuparadza ingot casting structure, kunatsa zviyo zvesimbi, uye kubvisa kukanganisa kwe microstructure, kuitira kuti chimiro chesimbi chive chakaoma uye michina inovandudzwa. Kuvandudzika uku kunonyanya kuratidzwa mugwara rekukunguruka, kuitira kuti lsaw simbi pombi haisisiri isotropic muviri kune imwe nhanho; mabhubhu, kutsemuka uye kusununguka kwakaumbwa panguva yekudururwa kunogonawo kusungirirwa pasi pekushisa kwakanyanya uye kumanikidzwa.

Kuipa kwe lsaw simbi pombi
1. Residual stress inokonzerwa nekutonhodza kusina kuenzana. Residual stress is the stress of internal self-phase equilibrium pasina simba rekunze. Kupisa kwakaputirwa simbi yezvikamu zvakasiyana-siyana ine kusara kwakadaro kunetseka. Iyo yakakura saizi yechikamu chesimbi yakawanda, iyo yakakura yekusarira kunetseka. Kunyange zvazvo kushushikana kwakasara kuri kuzvidzora, kunoramba kune imwe simba pamusoro pekushanda kwezvikamu zvesimbi pasi pemasimba ekunze. Semuenzaniso, inogona kuva nemigumisiro yakaipa pa deformation, kugadzikana, uye kuramba kuneta.

2. Mushure mekuputika, iyo isiri-metallic inclusions mukati me lsaw simbi pombi inomanikidzwa kuita zvidimbu zvitete, uye chiitiko che delamination chinoitika. Iyo delamination inoshatisa zvakanyanya zvimiro zve lsaw simbi pombi munzira ukobvu, uye inogona kuderera pamusono we weld. Interlaminar kubvarura kunoitika. Nharaunda yemunharaunda inokonzerwa ne weld shrinkage inowanzosvika kakawanda kune kukohwa kwegoho, iyo yakakura zvikuru kudarika dambudziko rinokonzerwa nemutoro.
