Abstract:The technology of soft-contacting electromagnetic continuous casting(SCEMCC) had been developed for several decades. However,it still needs to find a right point for commercial applications. throug analyzing the different of resistivity characteristics between stainless steel and carbon steels, and the pilot experimental results of 304 round billet SCEMCC,the feasibility of stainless steel SCEMCC was confirmed. Then,the new systems of round billet and square billet SCEMCC were developed respectively for industrial production experiments with different stainless steel grades and mold flux powders. The industrial production experimental result shows that the SCEMCC systems were effective and reliable to reduce the depth of almost all billet oscillation marks from about 0.7 mm to near zero,under the condition of 150 kW output power to the electromagnetic casting mold. Using obtained SCEMCC billets for milling [?]8 mm steel wire rod products,then processing with solution heat treatment and acid pickling,the material yield of end wire rod products can be increased more than 3%. Many times industrial continuous casting production experiments,in which the phenomenas of meniscus abnormal fluctuation and slag entrapped defects of billet macro structure were not being found,promoted SCEMCC taking a key step on business operation. Finally,the feasibility of SCEMCC from the billet section expending to the slab was discussed.
