Crystallization Behavior Evaluations of Mold Powder by Differential Thermal Analysis

摘要

One of the roles of mold pow?der in the continuous cast?ing process is the prevention of strand surface cracking. Mold pow?der selection is particularly impor?tant on crack-sensitive steel grades, including peritectic and medium-carbon grades. High-crystallization-temperature/high-basicity mold powder is a common and effective method to prevent surface cracking due to its softer heat removal.
