Abstract

The invention relates to ferro sulphur and a preparation method thereof. The ferro sulphur comprises, by weight, 50-70 parts of iron, 15-25 parts of sulphur and 5-35 parts of iron sulfide. The preparation method comprises the steps that the prepared raw materials are smelted, deslagged, molded, smashed, graded, packaged and pressed into balls in sequence. Technology research and development are carried out for a formula and preparation of the ferro sulphur, the raw material utilization rate is improved, and the production cost is reduced. The ferro sulphur has the beneficial effects that the production efficiency is high, materials and cost are reduced, the mold service life is long, no pollution is produced, energy consumption is low, heating is uniform, and the temperature control precision is high.

Description
