Metal melting furnace vortex chamber body and metal melting furnace using the same

Abstract

A metal melting furnace includes: a furnace body which includes a storage space storing molten metal; a vortex chamber body which includes a vortex chamber capable of communicating with the storage space of the furnace body; and a drop weir part which changes a communication state and an interruption state between the storage space and the vortex chamber, wherein the drop weir part includes a blind drop weir and an opening type drop weir which are formed as separate members, wherein at least the blind drop weir is movable up and down with respect to the vortex chamber body and is selectively positioned at an upward movement position and a downward movement position so as to switch the communication state and the interruption state, and wherein the opening type drop weir includes notches which communicate the vortex chamber and the storage space with each other in the communication state.
