Title:
METHOD FOR SHIFTING MOLTEN CUPPER OR CUPPER ALLOY
Document Type and Number:
Japanese Patent JP3178297
Kind Code:
B2
Abstract:
PURPOSE: To provide a method for shifting molten Cu or Cu alloy capable of preventing the O2 concentration in the molten metal under shifting from being increased, and capable of manufacturing the slab of oxygen-free level even with a general melting and casting equipment.
CONSTITUTION: In shifting the molten Cu or Cu alloy where the O2 concentration is ≤10ppm through the deoxidizing treatment in the melting process to the casting process, the molten metal head part where the head is at least 20m among the molten metal head parts to be present in the molten metal shifting process from a melting furnace to a casting mill is covered by a covering member, and the inert gas flow is formed in the covered area.
