Abstract
Description
technical field
[0001] The invention relates to the technical field of titanium-based alloy smelting suction casting, in particular to a bottom-drain vacuum suction casting equipment for titanium-based alloy induction melting and a control method thereof. Background technique
[0002] The traditional titanium alloy melting process has undergone several stages of changes. The first is vacuum arc melting. The principle of this melting method is to use titanium ingots and water-cooled copper crucibles as positive and negative electrodes respectively, and to melt the titanium ingots through mutual discharge of a large amount of heat under high current conditions, thereby forming a molten metal in the crucible. The molten metal, and then complete the pouring.
[0003] The second is vacuum induction melting. The principle is to wrap the induction coil outside the split-type water-cooled copper crucible. The electromagnetic force generated by the induction coil acts on the metal i...
