Tracks: Caster Process Optimization

The Compact Endless Casting and Rolling Mill (CEM) is a hot rolled strip manufacturing process with a direct connection between one casting line and one rolling line. It necessarily requires sufficiently high casting throughput to meet the endless rolling conditions. POSCO CEM caster is normally run over 6 m/minute. Such a high casting speed causes extreme thermal load around the meniscus in the mold, which severely damages the copper plates as a consequence. Two kinds of copper alloy, CuAg and CuCrZr, were tested and showed different damage patterns. Damage mechanism was analyzed based on the mold heat flux data measured during a high-speed casting.
