Electric Arc Furnace (EAF)

Calderys is committed to providing complete refractory solutions for the electric arc furnace (EAF). Our complete refractory and services offering is tailored to specific EAF processes, utilizing our global and local manufacturing footprint, and dedicated technical support.

EAF A<p>The taphole assemblies can be provided either as one piece EBT or segmented, or as launder designs. Our EBT products have been carefully formulated, using the higher purity raw materials and production capability, to bring high level and consistent performance.</p> <p>Very high-end products to resist thermal stress and slag corrosion coming from the proximity of the electrodes or opposite side of the gas burners</p> <p>A tailor made solution to bring slag resistance and offers the best cost / performance balance.</p> <p>Precast delta roofs can be either modular or complete delta section, using the best in class monolithic product solutions. It ensures the highest level and consistent performance.</p> <p>Whether the bottom design is a full monolithic bottom or reinforced with a brick subhearth, we ensure product compatibility for best performance. Ramming products can be installed quickly, with minimal dust generation, easy compaction to ensure consistent strength development, and carefully designed particle size distribution for a high angle of repose for when steel banks need to be constructed.</p> <p>Calderys completes refractory solutions to EAF applications, bringing high quality safety lining bricks and backfill products, to provide the necessary security for safe EAF operations.</p>
