Abstract

The metal formed as a result of a single-stage aluminothermic process of getting iron-containing melts can be used in the foundry production (as a casting riser) and to obtain permanent joints (in seamless rail welding). Carbon materials guaranteeing the required refractoriness of casting molds used in processes of this kind are characterized by relatively high cost, which determines the necessity of searching their alternative. As a solution to this problem, we can propose the application of slags obtained as a result of aluminothermic processes. We present the results of experiments aimed at the determination of the effect of casting molds made of carbon and slag materials on numerous characteristics (chemical composition, microhardness, and structure) of the ingots of iron-containing alloys obtained as a result of aluminothermic remelting of thermite charges. The comparative analysis of the presented results enables us to assess the possibility of applying slags of aluminothermic process for getting iron-containing ingots.

铸型耐火材料对铝热法制备含铁合金性能的影响

获得含铁熔体的单阶段铝热过程形成的金属可用于铸造生产（作为铸造冒口）和获得永久接头（在无缝轨道焊接中）。在这种工艺中使用的碳材料保证了铸造模具所需的耐火度，其特点是成本相对较高，这决定了寻找替代品的必要性。为了解决这一问题，我们可以提出利用铝热法获得的炉渣。我们提出了一项实验结果，旨在确定由碳和渣材料制成的铸模对铝热重熔得到的含铁合金锭的许多特性（化学成分、显微硬度和结构）的影响。对所得结果的对比分析使我们能够评估应用铝热法炉渣制取含铁钢锭的可能性。
