Application

During solidification, steel shrinks likely to form shrinkage cavities, with varying degrees of severity depending on the steel grade. The corresponding area in the ingot is unusable for the subsequent forming process. For this reason, the ingot head is heated to minimize shrinkage and to force non-metallic inclusions to the surface. This task is performed by THERMO D3, with a specific consumption of 1,5 - 2,5 kg/ton of steel, depending on the ingot geometry.
