<p>To provide a device which is compact, requires a small installation space, and is easily maintained at low cost. A metal melting furnace includes: a furnace body which includes a storage space storing molten metal; and a vortex chamber body which includes a vortex chamber communicating with the storage space of the furnace body, wherein the vortex chamber body includes a partition plate which serves as a drop weir uprightly formed inside the vortex chamber, wherein the partition plate is disposed at a communication side with respect to the storage space in the vortex chamber so that the longitudinal direction of the partition plate follows the communication direction and divides the communication side so as to form first and second vortex chamber openings positioned at both sides of the partition plate and communicating with both the storage space and the vortex chamber, and wherein a molten metal whirling gap is formed between a front end portion of the partition plate positioned at the inside of the vortex chamber in the longitudinal direction and an inner wall of the vortex chamber body facing the front end portion.</p> |
