The formation of steel casts according to the models to be melt with the crystallization under the pressure

The object of investigation: the thin-wall steel casts of the responsible purpose. The purpose of the work: the development of technical solutions and creating the technological casting process by the molten models with crystallization under the pressure on its base, ensuring the obtaining of the thin-wall casts with the preset construction strength. The tests of mechanical properties, the fatigue tests, hydrotests, thermographing and modeling have been performed. The increase of density of the cast metal and elimination of the cast defects have been established, the heat-power parameters of the processes for receiving the molten models, sheath forms and casts have been justified. The distribution of the steel temperature in the metal receiver, filling of thin walls resulting from the pressure and steel consumption rate at the mould inlet have been established. The technological processes of receiving the models to be molten, sheath forms and casts allowing to use the casts instead of the roll stock, stamping and welded joints have been developed. The developed technological processes have been introduced in the experimental-industrial scale. The efficiency of the introduction: reduction of the electric power by 20%, the labour of mechanical treatment by 2 times, the rejection by 30%Available from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
