The production of low-carbon and medium-carbon ferrochrome is a strategically significant area for the metallurgical industry, particularly in the context of increasingly stringent environmental regulations and growing demand for high-quality alloying materials. The production of low-carbon ferrochrome allows for the production of strong yet lightweight alloys used in the automotive, aerospace, and construction industries. The use of such lightweight materials reduces energy consumption during operation, particularly in transportation and aviation. Currently, the domestic enterprise produces approximately 60,000 tons of products per year; however, there remains substantial potential for increasing capacity and improving technological solutions. Of particular relevance is the issue of slag formation containing hexavalent chromium, which poses a serious environmental risk.

This study aims to identify the optimal technology for the industrial complex of a future low-carbon ferrochrome production facility with expanded output capacity. The paper examines modern energy-efficient and resource-saving smelting methods, approaches to minimizing the formation of hexavalent chromium, as well as technologies for slag processing and detoxification. The implementation of the proposed solutions will enhance productivity, reduce environmental impact, and ensure the sustainable development of the enterprise.
