Information × Registration Number 0203U000915, 0100U000775 , R & D reports Title Development of Theoretical Basis and Mathematical Modeling of Process a Crystallization Killed Low-Alloying Nitrogen-Contain of Steels with the Purpose of Deriving Ingots with Dispersed Shrikage Hole. popup.stage_title Head Tregubenko G.N., Registration Date 26-03-2003 Organization National Metallurgical Academy of Ukraine popup.description2 The researches of redistribution of nitrogen between phases and process gas-formation are executed at crystallization killed low-alloy nitrogen-containing steels, are determined and the equations for account of the optimum contents of nitrogen in melt are checked experimentally up depending on chemical structure of steel, heat-physics and technological parameters having poured and crystallization of metal. The generalization of results of these researches has allowed to develop theoretical and technological bases of reception of ingots quiet low-alloy steels with dispersed shrikage hole with use of the established principles of active influence on process crystallization of metal with the increased contents of nitrogen.
