Abstract—To reduce the losses of ferrosilicon during heavy-medium separation, it is necessary to increase its corrosion and mechanical resistance with the obligatory preservation of magnetic properties. To form ferrosilicon powder with the specified physical and mechanical characteristics that meet the technological process requirements, an automated heat treatment process control system is designed. The formed nitrided layer thickness is found to be controlled by the holding time and temperature. The total processing time is 3 h, and the temperature can vary in the range 900–1000°C. At higher temperatures, intense growth of silicon nitride crystals occurs.

硅铁粉氮化控制系统

摘要--为了减少硅铁在重介分离过程中的损耗，必须在保证磁性能的前提下提高其耐腐蚀性和机械性能。为了使硅铁粉末具有符合技术工艺要求的特定物理和机械特性，设计了一种自动热处理工艺控制系统。形成的氮化层厚度由保温时间和温度控制。总处理时间为 3 小时，温度可在 900-1000°C 范围内变化。在较高温度下，氮化硅晶体会发生剧烈生长。

期刊介绍： Russian Metallurgy (Metally) publishes results of original experimental and theoretical research in the form of reviews and regular articles devoted to topical problems of metallurgy, physical metallurgy, and treatment of ferrous, nonferrous, rare, and other metals and alloys, intermetallic compounds, and metallic composite materials. The journal focuses on physicochemical properties of metallurgical materials (ores, slags, matters, and melts of metals and alloys); physicochemical processes (thermodynamics and kinetics of pyrometallurgical, hydrometallurgical, electrochemical, and other processes); theoretical metallurgy; metal forming; thermoplastic and thermochemical treatment; computation and experimental determination of phase diagrams and thermokinetic diagrams; mechanisms and kinetics of phase transitions in metallic materials; relations between the chemical composition, phase and structural states of materials and their physicochemical and service properties; interaction between metallic materials and external media; and effects of radiation on these materials.
