Abstract
A continuous casting apparatus for molten metal is equipped with a mold having an electromagnetic coil which imparts a low frequency alternating current to the initially solidified portion of a meniscus and is formed with a plurality of divided cooling portions wherein the divided cooling portions are formed with a plurality of cooling copper plates each having cooling paths and back plates. The outer wall of the divided cooling portions is formed by facing the cooling path side of each of the divided cooling copper plates to that of the corresponding nonmagnetic stainless steel back plate and closing and fixing both plates, and the cooling copper plates are electrically insulated from each other by bonding electric insulating material to the joint faces of the cooling copper plates.
