The benefits of the use of exothermic insulating materials during ingot casting process are presented on the animation below. Different insulating products were applied at the top of the mold during teeming and solidification. MAGMASOFT® casting simulation software was used to show the difference between uninsulated (left side of the animation) and insolated mold (right side). The difference is obvious. While uninsulated mold creates deep pipe, the well-insulated mold prevents occurrence of the pipe and create almost flat top surface.
