Abstract

An electron-microscopic study of the structural-phase composition of materials for late graphitizing modification of cast iron melt is carried out in the mold pouring bowl (FeSi75 lump (AO Chelyabinsk Electrometallurgical Integrated Plant (ChEMK))) and inside the mold (cast insert in the sump under the riser). The shape and location of the main phases with their individual morphological features, namely, size, casting defects, etc., are analyzed. A conclusion was made about a positive effect of ferrosilicon repeated remelting in the manufacture of the cast insert.

重熔和凝固特征对铸造快速冷却硅铁插件和硅铁块结构的影响

摘要对铸铁熔体后期石墨化改性材料的结构相组成进行了电子显微镜研究，研究对象包括铸模浇注碗（FeSi75 块状物（AO 车里雅宾斯克电冶综合厂（CHEMK）））和铸模内部（冒口下底盘中的铸造镶件）。分析了主要阶段的形状和位置及其各自的形态特征，即尺寸、铸造缺陷等。得出的结论是，硅铁反复重熔对铸件镶块的制造有积极作用。

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.
