Development of technology of technogenic wastes processing at smelting of qualitative stainless steels

Article preview

Temperature dependences of physical and chemical properties of liquid stainless steel have been investigated. The existence of critical temperatures, heating above which leads to irreversible changes in the structural state of the melt, has been substantiated. The influence of the amount of technogenic wastes on the physicochemical properties of liquid steels has been determined. A physical model of the structure of liquid stainless steels has been proposed.

Development of temperature-time regimes for melting quality steels with complex use of raw material resources

Article preview

The temperature dependences of kinematic viscosity of liquid stainless steels 10Х23Н18 and 20Х23Н18 have been studied. The existence of critical temperatures, heating above which is accompanied by irreversible changes in the structural state of the melt has been established. A model of the structure of liquid stainless steels has been proposed. The temperature-time regimes of stainless steels melting, providing the raw materials economy and improving the quality of metal products, have been developed.

Integrated recycling of metallurgical waste based on the study of high-temperature physical and chemical processes of melting alloys

Article preview

Measures for the use of anthropogenic metallurgical waste in the production of high quality alloys are proposed. The relationship between the amount of casting wastes in the charge with the type and features of temperature dependences of physical and chemical properties of the melt has been found. As the amount of waste increases, the critical temperatures increase. The use of high-temperature treatment of the melt can significantly improve the quality of castings from heat-resistant alloys containing a significant amount of casting man-made wastes in the charge.

Development of temperature and time modes of melting of quality steels with complex utilization of raw material resources

Article preview

Temperature dependences of kinematic viscosity of liquid stainless steel have been investigated. The existence of critical temperatures, heating above which leads to irreversible changes in the structural state of the melt, has been substantiated. Directed thermal influence on the melt based on its transition to another structural state allows to carry out melt solidification in various conditions, to regulate morphology and magnitude of structural composition and to develop scientifically grounded melting modes. A physical model of the structure of liquid stainless steels is proposed. The analysis of the obtained temperature dependences shows that liquid stainless steels can be in different states, the temperature fields of existence of which partially overlap.

Integrated processing of metallurgical production wastes on the basis of research of high-temperature physicochemical processes of metal smelting

Article preview

Measures for utilization of technogenic metallurgy wastes in the production of high quality alloys are proposed. Temperature dependences of physical properties of liquid superalloys are investigated, critical temperatures are determined, heating above which leads to irreversible intensive changes in the state of the melt. The relationship between the amount of cast waste in the scrap and features of temperature dependences of physical and chemical properties of the melt has been established. The increase in the amount of waste leads to the growth of critical temperatures. Application of high-temperature treatment allows to improve considerably the quality of casting superalloys, the scrap of which contains a large amount of foundry technogenic wastes.
