CONTINUOUS PRODUCING DEVICE FOR COMPOSITE INGOT

摘要

PURPOSE:To make stable mass production of a composite ingot having good quality with good wordability by inserting a heated core material through a tundish connected to a mold open at both ends into said mold and drawing continuously the resulted composite ingot. CONSTITUTION:The molten metal 31 is supplied into the tundish 23 connected via a refractory ring 22 to the top end of the mold 21 open at both ends and is preferably sealed by an inert gas such as Ar to prevent the oxidation thereof. The core material 24 is fed into the tundish 23 through an upper aperture 25 thereof by centering rolls 26 and after the core material is heated to a prescribed temp. by a heating coil 27, the material 24 is continuously inserted into the mold 21 through the above-mentioned connecting part. The composite ingot 28 having the good adhesiveness at the joint boundary and high quality is thus formed without the intrusion of scum and the abnormal wear and is continuously drawn together with a dummy 30 by pinch rolls 29.
