PROCESS FOR RECYCLING SIDE DAMS FOR THE CONTINUOUS CASTING OF THIN STEEL STRIP, AND BORON NITRIDE-CONTAINING POWDER MIXTURE AND SIDE DAM PRODUCED THEREBY

摘要

Process is for environmentally friendly, low-waste reprocessing of side dams for the continuous casting of thin steel strip having a mechanically or chemically worn surface. The mechanically or chemically worn surface of the side dams is cleaned by methods known per se and the side dams are subsequently converted into a BN-containing powder by crushing and milling.
