In view of the various demands on specialty graphites used for continuous casting, SGL Group group has developed special graphite grades to meet the specific requirements of the different applications.

Due to the high thermal conductivity of graphite, there is a risk of "chilling in" at the edges of rectangular or square sections of cast iron. To avoid these undesirable and extremely hard structures, the corner strips of split molds are made of carbon grades with low thermal conductivity. Thus, the cooling process at these critical points is delayed. The RINGSDORFF^® R4261H grade has proved to be very effective in this respect.
