A wall of a mold assembly for the continuous casting of steel has a steel back-up plate. A thermally conductive plate composed of copper or a copper alloy is bolted to the back-up plate and a relatively thin copper or copper alloy facing is soldered to that surface of the thermally conductive plate which faces away from the back-up plate. The thermally conductive plate may be omitted and the facing soldered to the back-up plate. The facing contacts and cools a continuously cast strand travelling through the mold. When the facing becomes cracked or worn beyond repair, the solder joint is melted to remove the facing and a fresh facing is soldered to the thermally conductive plate or back-up plate. |
