Influence of Casting Process for Technological Yield of Thin Wall Steel Castings by Last Solidifying Feeding Mechanism

Abstract:

For the steel castings which is thin wall, uniform thickness, complex structure, and no special mechanical properties, it is feasible that the foundry technology was designed according to the last solidifying feeding mechanism. Adopting this process for the thin wall steel castings, the pouring temperature must be controlled and the gating system be designed rationally. Using self-feeding shrinkage in solidification, and the casting was poured and congealing at the same time. The shrinkage of finally congealing part was fed by small riser or gating system (no riser). Using this foundry technology, the casting process yield and surface quality of casting may be improved, the production cost is reduced, and the requirements of mechanical properties can be met.
