摘要

During 35 years in Insitute of foundry problems laws of mass-heat-exchange process, gashydrodynamics, solydification conditions and conditions of structure-quality formation of castings made of ferrous and non-ferrous alloys by Lost-foam technology are investigated, and new types of Lost-foam technology are created on this basis.Recently in IFP new theoretical visions and representations about gas-hydrodynamic processes, structure and usage characteristics foramtion of cast products and interaction of liquid, solydifying metal with thermal-destruction products of polystyrene model's (with presence of macro-and fine reinforcement elements in it) are proved, even with applying of the high control pressure on liquid and solydifying metal.
