Abstract
A continuous casting device capable of giving lubricating property to a molten metal pouring nozzle without increasing lubricating oil and performing casting with high casting surface quality for a long period of time is provided. In a continuous casting device 1 in which a molten metal pouring nozzle 20 is arranged between a molten metal receiving portion 10 and a mold 40, the molten metal pouring nozzle 20 is equipped with a cylindrical main body portion 22 made of a fire-resistant substance and having a molten metal passage 21, and an annular member 30 having self-lubricating property is arranged on a mold-side end face 23 of the main body portion 22 so as to surround the molten metal passage 21.
Claims8
A continuous casting device in which a molten metal pouring nozzle is arranged between a molten metal receiving portion and a mold,
- wherein the molten metal pouring nozzle is equipped with a cylindrical main body portion made of a fire-resistant substance and including a molten metal passage,
- wherein an annular member having a self-lubricating property is mounted in a stepped portion of the main body, on a mold-side end face of the main body portion, so as to surround the molten metal passage, and
- wherein an inner diameter of the annular member is larger than a diameter of the molten metal passage, and the main body portion is exposed at an inner side area continuing from the molten metal passage in a portion facing a molding hole of the mold.
