<p>The present invention relates to a chute and, more particularly, to a chute which supplies a raw material supplied from the outside to a smelting furnace, by comprising a bin where a raw material is supplied; and a supplying pipe which is connected with the bin and inclines at a preset angle. The chute has a first speed reducing plate and a speed reducing protrusion which protrude from the inner circumferential surface of the supplying pipe. The length of the first speed reducing plate is longer than the length of the speed reducing protrusion.</p> |
