Metal fusion device for casting metallic products, has high frequency-regenerative system, worm shovel formed around outer surface of air channel of gear, and fusion material supply device arranged on cover and extended into furnace body

摘要

The device has a high frequency-regenerative system (30) comprising a regenerative heating area (31) and recycling air with high temperature from a heating furnace (10). A raw material supply device (40) has a supply pipe (41) connected with a furnace body. A preheating worm gear (42) is arranged in the pipe, and has an air channel (421) with an inlet connected with an outlet of an air channel (32) of the system. A worm shovel (423) is formed around an outer surface of the channel of the gear. A fusion material supply device (52) is arranged on a cover (22) and extended into the body. An independent claim is also included for a method for melting metal in a metal fusion device.
