Development of vacuum jet steel refining technology with consideration of hydrodynamic factors during it's casting

The machine steel was studied. The purpose was the obtaintion of additional data on the steel jet flow in the vacuum, the development of technological methods, allowing to intensify the jetvacuum processes. New data on the regime of steel jet flow in the vacuum were obtained with consideration of the hydrodynamic factors. It was established that the over-heating of steel determins the regimes of it's flow in the vacuum. The results of investigations were used in a new method for jet vacuum steel refining. A new technology for vacuum steel treatment has been got adopted in Uralmash workAvailable from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
