| 摘要 |
The present invention relates to a process for preparing a foaming slag former 40 for electric arc furnaces 1, with at least 20 wt. % of solid slag particles, to the product of this process, and to its use in electric arc furnaces 1. The process of the invention comprises the steps of aggregating solid slag particles into a coarser granular material 33 and carbonating them to produce said slag former 40. In a preferred embodiment, said solid slag particles are aggregated before said carbonation, so that the carbonates form a solid matrix binding the particles together.
