Claim Text:
1. A metal melting furnace vortex chamber body with a vortex chamber communicating with a storage space of a furnace body having the storage space storing molten metal, the metal melting furnace vortex chamber body comprising: a communicating side or a communicating opening formed in a part of a side wall, the vortex chamber of the vortex chamber body and the storage space of the furnace body communicating through the communicating opening, a shape of a cross-section of the side wall of the vortex chamber being substantively U-shaped, the vortex chamber being a space surrounded by the side wall, the vortex chamber having a given first width, a given first length and a given first height, and a partition plate which is made of a flat plate and is uprightly arranged inside the vortex chamber of the vortex chamber body, the partition plate having a given second width, a given second length and a given second height, wherein the partition plate is disposed at a communication side with respect to the storage space in the vortex chamber so that the second length direction of the partition plate follows the first length direction of the vortex chamber, and the partition plate 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, the first and the second vortex chamber openings line along the first and the second width directions, wherein a gap is formed between a front end portion of the partition plate positioned at the inside of the vortex chamber in the second length direction and an inner wall of the vortex chamber body facing the front end portion, wherein the first vortex chamber opening and the second vortex chamber opening communicate via the gap, and wherein the partition plate is detachable from the vortex chamber, a communicating opening reappearing by removing the partition plate so that the vortex chamber of the vortex chamber body and the storage space of the furnace body communicate through the communicating opening.
