Apparently, the described embodiments are some, but not all, of the embodiments of the present utility model.

[0022] By providing a ladle nozzle flow regulating device in the embodiments of the present application, the problem that the flow of the traditional ladle nozzle is usually controlled by a control valve is solved. However, during the process of controlling the flow of the ladle nozzle, due to the periodic operation of the sliding nozzle position, this reciprocating motion will increase the wear of parts, reduce the service life of the nozzle, and at the same time, it is not convenient to control accurately, and the maintenance is not convenient enough after the parts are damaged.
[0023] To better understand the above technical solutions, the above technical solutions will be described in detail below in conjunction with the accompanying drawings of the specification and specific implementation manners.
[0024] The embodiments of the present utility model disclose a ladle nozzle flow regulating device. As shown in the attached Figures 1-4 figure, it includes a flow regulating valve 1. A nozzle structure 2 is provided at the bottom of the flow regulating valve 1. L-shaped mounting platforms 3 are provided on both sides of the nozzle structure 2.

A positioning rod 301 is fixedly connected to the L-shaped mounting platform 3, and the positioning rod 301 is movably clamped in the positioning hole 402.
[0025] Through the design of the L-shaped mounting platform 3, the electromagnetic device 4 is conveniently installed on the nozzle structure 2. The magnetic field generated by the electromagnetic device 4 is applied inside the nozzle structure 2. When the molten steel is discharged through the principle of electromagnetic induction, an induced current and an induced magnetic field are generated during the process that the molten steel crosses the magnetic field and cuts the magnetic force lines. The two magnetic fields interact with each other to apply a resistance to the molten steel, thereby regulating the flow rate of the molten steel. This regulation method has a simple structure, is non-contact, and is convenient to operate.

[0028] Through the design of the locking mechanism 5, the disassembly and assembly of the electromagnetic device 4 are convenient, thus ensuring the convenience of the maintenance and subsequent replacement and upgrade operations of the electromagnetic device 4. When installing the electromagnetic device 4, first pull the two groups of sliders 502, so that while the sliders 502 drive the locking rods 503 to move, the springs 504 are compressed. At this time, the positioning holes 402 on the electromagnetic device 4 are engaged with the positioning rods 301. After the engagement, release the sliders 502, and the springs 504 reset and push the sliders 502 and the locking rods 503 to move, so that the locking rods 503 are inserted into the inside of the locking holes 401.
[0029] A clamping strip 505 is fixedly connected to the L-shaped mounting table 3. A clamping groove 506 is formed on the slider 502, and the clamping groove 506 is engaged with the clamping strip 505. A handle groove 507 is formed on the slider 502. Through the design of the clamping groove 506 and the clamping strip 505, the force on the slider 502 is stable. Through the design of the handle groove 507, the movement of the slider 502 is convenient.
[0030] A protective cover 403 is provided on the electromagnetic device 4. Through the design of the protective cover 403, the outer corners of the electromagnetic device 4 are protected from being bumped and damaged.
