Description

TECHNICAL FIELD

[0001] The utility model belongs to metallurgical technical field, concretely relates to a continuous casting machine tundish baffle suspension device. BACKGROUND

[0002] The continuous casting machine tundish is a transition device connecting a ladle and a crystallizer, mainly used for protecting molten steel, distributing molten steel, stabilizing flow and purifying molten steel in the continuous casting production process. The tundish is a container made of refractory material, usually composed of a shell 1, a cover, a nozzle and a stopper. The shell 1 usually has a plurality of openings 10, which help the refractory material to better ventilate during continuous casting, thereby ensuring stable operation and efficient operation of the tundish. However, the openings 10 can cause the molten steel to splash out of the openings 10, posing a safety risk.

[0003] In order to prevent the molten steel from splashing out of the openings 10 during production and causing safety accidents such as scalding, a baffle 2 is provided on the outer wall of the shell 1, which is suspended by a traditional suspension method, as shown in Figure 1 The shell 1 has a hanging ring 11 welded on the outer wall, and the upper part of the baffle 2 has a T-shaped baffle hook 12, which suspends the baffle 2 on the outer wall of the shell 1 by the baffle hook 12, blocking the molten steel from splashing outwards.

[0004] However, this suspension method has certain drawbacks. Since the baffle 2 is subjected to the scouring and beating of the high-temperature molten steel flowing in the continuous casting machine tundish over the years, it will gradually deteriorate as the service life increases, failing to meet the use requirements, so a baffle 2 needs to be replaced every certain period of time. However, in the above suspension method, if the cross arm of the T-shaped baffle hook 12 is too long, it is very difficult to disassemble and install the baffle hook 12, which is time-consuming and laborious; if the cross arm of the T-shaped baffle hook 12 is too short, it is easy to cause one end of the baffle hook 12 to fall off from the hanging ring 11, resulting in the whole baffle 2 falling off and causing a safety accident.
