The paper presents results of testing semi-coke as a carbon reducing agent in the production of manganese and silicon alloys. The fundamental possibility of using semi-coke in the carbon part of the charge as a basic reducing agent to produce ferrosilicon manganese is established. It is noted that a new reducing agent in its pure form works worse than in a mixture with coal. The greatest synergistic effect in the production of ferrosilicon manganese was achieved during the interaction of semi-coke with coal, while the following indicators were obtained: maximum furnace productivity of 43 t/day, maximum extraction coefficient of 87.9%, and minimum specific dust formation of 49 kg/t of alloy. In the production of ferrosilicon, the use of a new reducing agent did not give a significant positive effect, due to its low structural strength. It was revealed that the structure and type of the reducing agent affect the furnace performance: when using a reducing agent with a higher reactivity in the charge, it is possible to obtain higher furnace performance. In the production of ferrosilicon, a change in the specific dust generation is closely related to the level of daily production and specific energy consumption and can serve as an indicator of furnace operation. The furnace performance, ceteris paribus, is determined by the amount of useful power input. With an excess of carbon in the charge an increase in useful power leads to a slight increase in the furnace performance, but at the same time, the energy consumption and specific dust formation significantly increase. It is shown that the influence of technological factors on the technical and economic indicators of melting is determined by the degree of electrode seating in the furnace.

半焦在锰硅合金生产中作为减碳剂的技术适用性

本文介绍了半焦作为锰和硅合金生产中的碳还原剂的测试结果。确定了在炉料的碳部分使用半焦作为碱性还原剂生产硅铁锰的基本可能性。值得注意的是，纯形式的新还原剂比与煤混合的还原剂效果更差。硅铁锰生产的协同效应在半焦与煤的相互作用过程中发挥最大，同时获得以下指标：最高炉产量43吨/天，最大提取系数87.9%，最小特定粉尘形成49 公斤/吨合金。在硅铁生产中，由于结构强度低，使用新的还原剂并没有产生显着的积极效果。结果表明，还原剂的结构和类型会影响熔炉性能：当在炉料中使用具有更高反应性的还原剂时，可以获得更高的熔炉性能。在硅铁生产中，特定产尘量的变化与日产量和单位能耗水平密切相关，可以作为熔炉运行的一个指标。在其他条件不变的情况下，熔炉性能由输入的有用功率量决定。炉料中碳含量过多时，有用功率的增加会导致炉子性能略有提高，但与此同时，能耗和特定粉尘的形成显着增加。
