Description

technical field [0001] The invention relates to the field of production technology, in particular the invention relates to an environment-friendly iron-based material production technology system. Background technique [0002] The main raw materials for the traditional production of ferrosilicon are silica, steel shavings and coke. Steel shavings are an important raw material for smelting ferrosilicon alloys. The annual consumption is about 2 million tons, while the output is only about 1.8 million tons. Affected by factors such as electricity prices, ore, common carbon steel shavings, and overcapacity in recent years, ferroalloy enterprises are facing a difficult situation. Therefore, the use of cheap raw materials to replace traditional process materials is an inevitable development direction of ferroalloys in the future. [0003] On the other hand, my country's low-grade hematite resources are very rich, and a large number of lean iron ore resources with fine particle si...
