Description of invention (2) 9 The upper end surface is tightly connected to the lower end surface of the chute nozzle 18 by a sealing ring (not shown), and the outer surface of the nozzle housing 10 is protrudingly provided with support pins 19, 19 at the symmetrical position of its diameter . The lower part of the immersion nozzle 9 is frequently immersed in the molten metal as shown above. Since it is in the state of being washed by the molten metal, it will be worn out, and it needs to be replaced with a new immersion nozzle 9 in due time. . Therefore, in the past, the nozzle supporting device 11 of the immersion nozzle 9 was replaced as soon as possible. In the previous example shown in the eleventh circle, below the slide valve device 6, an air cylinder 2 1 is provided with a piston rod 20 facing downward, and a support arm 2 2 is fixed to the piston rod 20 of the air cylinder 21 , And the front end side of the support arm 22 is provided with a concave portion 23 held in a suspended state by the support pins 19, 19 of the nozzle housing 10, and when the concave portion 23 is fitted After the support pins 1 9, 19 of the immersion nozzle 9, shorten the air cylinder 21 so that the upper end surface of the immersion nozzle 9 moves below the periphery of the hole 17 of the sliding plate 16 of the slide valve device 6, and then slides When the valve device 6 is provided with a chute nozzle 18, the immersion nozzle 9 is pressed against the chute nozzle 18 by a sealing ring, and it is fixed. The means of fixing may also be a lever or a toggle mechanism. However, in the above device, when you want to replace the immersion nozzle 9, you must first slide the slide plate 16 of the slide valve device 6 to make it closed, and then raise the feed tank 1 to make the air cylinder 21 Extend the action to lower the support arm 22, remove the immersion nozzle 9 by hand, and after cleaning the chute nozzle 18, set a new sealing ring of the immersion nozzle 9, then make the air red, 2 1 Shrink_short action to raise the immersion type.

Description of the invention (3) Injection port 9, while lowering the feed trough 1, opening the sliding valve device 6 and other procedures, so this The replacement operation takes as fast as 60 to 90 seconds. As a result, during the replacement of the immersion nozzle 9, the surface of the molten metal 13 in the mold 12 will harden, and the joint portion of the molten metal 13 will become scrap The ratio will increase, and there is a big problem of reducing the yield. The flow-out time of molten gold 13 is interrupted, but because the used immersion nozzle must be pulled out before the new immersion nozzle 9 can be replaced (inserted), the time that can be shortened also has its limits, or not The feed trough 1 is moved up and down without omitting the time required, but the presence of the slide valve device 6 makes the space below it very narrow, and the replacement operation in this narrow space is more time-consuming and difficult to implement Quick replacement. The above replacement work is done by hand, because the immersion method is itself made of brick, so the replacement is very large, and its installation and removal work is not easy, and the temperature around the sliding valve device 6 Very high, so it is difficult to work in a high-heat environment. On the other hand, in order to make the replacement of the immersion nozzle easy, such as the technology described in USP 4,669,528 patent specification. This technology is in The lower part of the fixed plate is provided with a sliding mechanism, and the upper combined plate-shaped brick is made of a thin iron plate shell to make it into a special immersion nozzle, which is supported from below The front and rear parts of the lower part of the housing part are biased upward by the spring plucking, so that it slides on the guide rail, and the top of the slab gate brick of the immersion spout is pressed and fixed by the shape of the guide rail It is composed of the bottom of the board. This paper scale is applicable to the Chinese seabream national standard (CNS) A4 specification (210X297mm) ~~ (please read the notes on the back to write this page-installation-line 315336 A7 B7 Central Economic Ministry Printed by the WC Industry Consumer Cooperative Society of the Kneading Bureau 5. Description of the invention (4) Therefore, when the immersion nozzle is to be replaced during continuous sickling, a new immersion nozzle is installed on the sliding mechanism and an immersion nozzle is installed at the same time Push in the cylinder, then after closing the insertion nozzle by the stopper, push the immersion nozzle through the cylinder, and then open the stopper, take out the used immersion nozzle, the time required for this procedure is roughly 1 0 ~ 15 seconds, so it can be replaced faster than the above-mentioned prior art * However, in the above device, it is necessary to use a special combination of slab-shaped bricks on the upper part of the immersion type mouth to make it integrated with the shell. Immersion nozzle Therefore, the price of the nozzle becomes expensive, which is about 1.5 times the price of conventional products, which causes a problem of increasing operating costs. In addition, due to the method of pushing from the bottom of the housing of the immersion spout, the inner and outer plate-shaped bricks are easily deformed into a curved shape, so a gap will occur between the joint surface with the fixed plate. Inhalation occurs at this location, which leads to problems such as abnormal melting loss or deterioration of steel quality. Another example is when the slab brick cracks, the phenomenon of hot metal immersion occurs and even constitutes a serious accident of steel leakage. The stopper is used to control the molten metal, so there is a problem that it is easy to attach Aj? 20 3 to the head of the stopper and it is difficult to control the flow. The purpose of the present invention is to provide a limit to shorten the casting interruption time caused by the replacement of the immersion nozzle, which can reduce the scrap of molten gold and improve the yield rate, and reduce the immersion of people in harsh environments. Replacement device for type sprue. In addition, the present invention does not require a special structure for the immersion nozzle, and can use a simple and inexpensive immersion nozzle. In addition, the present invention supports the immersion along the entire circumference by a nozzle-like hip; the upper part of the nozzle is not immersed, and the size of the paper is not used.
