Problems solved by technology

However, the closed contact of the existing stopper rod-nozzle flow control structure is realized through the tangential cooperation between the arc-shaped head of the stopper rod and the arc-shaped opening of the nozzle. The relationship between is a nonlinear relationship, which is difficult to calculate and control

Embodiment Construction

[0015] The present invention will be described in further detail below by means of specific embodiments:

[0016] The reference signs in the drawings of the specification include: tundish body 10, liquid outlet pipe 11, liquid outlet tank 111, stopper 20, liquid outlet 21, through hole 22, stopper rod 30, liquid inlet 31, grip ring 32 .

[0017] Such as figure 1 As shown, the tundish with speed regulating function includes a tundish body 10 , a stopper rod 30 , a liquid outlet pipe 11 and a stopper 20 . A second cavity is processed in the stopper rod 30, and a liquid inlet 31 communicating with the second cavity is also provided on the stopper rod 30. The upper end of the stopper rod 30 is welded with a grip ring 32, and the stopper 20 is welded on the The lower end, and the first cavity communicates with the second cavity.

[0018] Such as figure 2 , image 3 As shown, the block 20 is processed with a first cavity and a liquid outlet 21 communicating with the first cavi...

Abstract

The invention belongs to the field of casting melt containers, and particularly relates to a tundish having a speed regulation function. The tundish comprises a tundish body and a stopper rod, and further comprises a liquid outlet pipe and a stop dog. A first cavity and a liquid outlet communicated with the first cavity are formed inside the stop dog. The liquid outlet pipe is arranged at the bottom of the tundish body. A plurality of liquid outlet grooves of different sizes are formed in the inner wall of the liquid outlet pipe and are smaller than the liquid outlet. The liquid outlet pipe is connected to the stop dog in a sleeved manner. A second cavity is formed inside the stopper rod which is further provided with a liquid inlet communicated with the second cavity. The stop dog is fixed to the stopper rod. The first cavity is communicated with the second cavity. Compared with a traditional stopper rod-water gap flow control structure, it is not needed to consider the relation between the vertical movement distance of the stopper rod and the open area of a water gap, and it is only needed to machine the liquid outlet grooves of certain sizes in the liquid outlet pipe in advance and rotate the stopper rod to make the liquid outlet of the stop dog communicated with one liquid outlet groove, so that operation is easy, and flow rate control is more accurate.

Description

technical field [0001] The invention belongs to the field of casting melt containers, in particular to a tundish with a speed regulating function. Background technique [0002] The tundish is an important metallurgical process equipment. It is not only a buffer to distribute and ensure the continuous casting of molten steel, but also a key equipment to ensure the quality of casting slabs such as removing non-metallic inclusions, uniform temperature of molten steel, and preventing steel slag from entering the crystallizer. Its metallurgical The effect directly affects the quality of the slab. In actual operation, it is often necessary to effectively control the flow rate of the tundish. [0003] The stopper rod-nozzle flow control structure is a commonly used flow control structure in the pouring control of the tundish. This structure includes a liquid outlet arranged on the bottom surface of the tundish and a stopper rod matched with the liquid outlet. The opening of the n...
