The presentation will cover the definition of steel and its constituents, oxidation, carbon boil, a description of slag formation and foaming, an introduction to alloying for chemical properties, the impact of dissolved gases in the melt, and deoxidation. A brief description of laboratory analysis and SPC uses will also be included. The presentation will cover the types, sizing, usage and calculations for proper alloying of a heat. Also presented will be various methods used to make an alloy addition to the furnace. An introduction to slag fundamentals and their practical application to foaming in the EAF and refining in the ladle.
Specific attention is given to slag optimization for steel quality and refractory protection.
An introduction to automation, process control and power programs for electric arc furnaces. The presentation will focus on conductive power components, various designs and their features. Important maintenance suggestions will be made and problem areas that are often overlooked will be identified along with practical remedies for increased operating reliability. This presentation will describe refractory raw materials and simple descriptions of refractory properties in mortars, plastics, ramming mixes, castables and bricks. Refractory selection and installation for sidewalls, bottoms, door jambs, tapholes, runners, roofs and deltas will be included, as well as the proper heat-up procedures, maintenance and typical wear mechanisms in the electric arc furnace.
