Searching for alternatives to diversification of production facilities that do not require significant material and energy costs is relevant in the face of pressing external factors. One of the promising technological fields of alloy production in metallurgy is the application of aluminothermic processes of remelting of thermite charge consisting of secondary materials (scale, chips of ferrous and nonferrous metals), used to produce a wide range of metal products without significant costs associated with the reequipment of production units. The possibility of controlling the parameters of alloys and properties of the final metal product formed by aluminothermic processes is implemented primarily by reducing the temperature of the metal phase of the melt by introducing inert fillers into the composition of mixtures, as well as holding the melt in the crucible before casting. The chemical composition, structure, and physical and mechanical properties of iron-carbon alloys are significant in forming several operational characteristics. The paper presents experiments aimed at studying the effect of the initial components of thermite charge materials used to produce iron-carbon alloys in aluminothermic processes, as well as the melt holding time in a crucible before casting on the chemical composition, microstructure, hardness, strength indicators, and the fracture characteristics. The focus of experimental investigations is on industrial applications in the metallurgical and machine-building sectors.

面对紧迫的外部因素，寻找不需要大量材料和能源成本的生产设施多元化替代方案是相关的。冶金合金生产中最有前途的技术领域之一是应用由二次材料（铁皮、黑色金属和有色金属碎片）组成的铝热炉料重熔的铝热工艺，用于生产各种金属产品，而无需大量相关成本随着生产单位的重新装备。控制铝热工艺形成的最终金属产品的合金参数和性能的可能性主要是通过将惰性填料引入混合物的成分中来降低熔体金属相的温度，以及将熔体保持在铸造前的坩埚。铁碳合金的化学成分、结构以及物理机械性能对于形成多种操作特性具有重要意义。本文介绍了旨在研究铝热法生产铁碳合金的铝热炉料的初始成分以及铸造前熔体在坩埚中的停留时间对化学成分、显微组织、硬度、强度的影响的实验。指标和断裂特征。实验研究的重点是冶金和机械制造领域的工业应用。
