Description

Technical Field

[0001] The utility model relates to a water inlet anti-blocking device for a steelmaking furnace used for producing ultra-microcrystalline ribbons, belonging to the technical field of ultra-microcrystalline ribbon production. Background Art

[0002] Steelmaking furnaces can generally be divided into three types: converters, open hearth furnaces and electric furnaces. Steel is obtained by putting pig iron for steelmaking into a steelmaking furnace and melting it according to a certain process. Steel products include ingots, continuous casting billets and various steel castings directly cast. Steel usually refers to steel rolled into various steel products. Steel belongs to ferrous metals, but steel is not completely equal to ferrous metals. Steelmaking refers to controlling the carbon content (generally less than 2%), eliminating harmful elements such as P, S, O, and N, retaining or increasing beneficial elements such as Si, Mn, Ni, and Cr, and adjusting the ratio between elements to obtain the best performance.

[0003] There are still some problems in the use of an existing steelmaking furnace device for producing ultra-fine crystal strips. The water inlet anti-clogging device of the steelmaking furnace for producing ultra-fine crystal strips cannot quickly clean the solidified molten steel in the water inlet when in use, which affects the use efficiency. Utility Model Content

[0004] The purpose of the utility model is to provide a water nozzle anti-clogging device for a steelmaking furnace used for producing ultra-fine crystal strips. The utility model has a simple structure and is easy to use. It can quickly clean the solidified molten steel inside the water nozzle to prevent the water nozzle from being blocked, thereby solving the problems raised in the above-mentioned background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] Furthermore, an extrusion rod is fixedly connected to the outer side of the fixed block, a power box is fixedly connected to the outer side of the L-shaped plate, a switch is fixedly connected to the top of the power box, a return spring is fixedly connected to the inner side of the switch, a wire is fixedly connected to the outer side of the power box, and a heating coil is fixedly connected to the outer side of the water outlet pipe.

[0008] Furthermore, the pushing rod is movably connected to the outer side of the connecting plate through a screw rod, and the electric telescopic rod is slidably connected to the top of the L-shaped plate.

[0009] Furthermore, the electric telescopic rod is electrically connected to the motor and the controller, and the lifting rod is movably connected inside the moving groove.

[0014] (I) The utility model is provided with a steelmaking furnace body, and an L-shaped plate is fixedly connected to the outer side of the top of the steelmaking furnace body. When molten steel solidifies inside the water outlet pipe, the screw is first rotated to rotate and move inside the threaded tube. At this time, the screw drives the push rod to rotate and move. Since the end of the push rod away from the screw is rotated and clamped inside the fixed block, the fixed block can be driven to move when the push rod moves, so that the electric telescopic rod moves on the top of the L-shaped plate. When the electric telescopic rod moves to the top of the water outlet pipe, the controller starts the electric telescopic rod, so that the electric telescopic rod drives the lifting rod to move downward, so that the crushing column at the bottom of the motor moves to the inside of the water outlet pipe. At this time, the controller starts the motor, so that the motor drives the crushing column to rotate, and the crushing column can crush the solidified molten steel inside the water outlet pipe.

[0015] (ii) The utility model is provided with a steelmaking furnace body. When the fixed block drives the electric telescopic rod to move to the top of the water outlet pipe, the extrusion rod on the outside of the fixed block pushes the switch, thereby turning on the switch. At this time, the power box is energized, and the power box and the wire are used in conjunction to start the heating coil on the outside of the water outlet pipe, so that the molten steel remaining on the inner wall of the water outlet pipe after being crushed inside the water outlet pipe is thermally treated, thereby achieving the effect of preventing blockage.

[0026] Specifically, Figure 1 As shown, the pushing rod 9 is movably connected to the outside of the connecting plate 6 through the screw 8, the electric telescopic rod 11 is slidably connected to the top of the L-shaped plate 5, the electric telescopic rod 11 is electrically connected to the motor 14 and the controller 2, the lifting rod 12 is movably connected to the inside of the moving groove 13, the initial position of the crushing column 15 is on the outside of the water outlet pipe 4, and the rotation range of the crushing column 15 is smaller than the diameter inside the water outlet pipe 4.

[0027] In this embodiment: a steelmaking furnace body 1 is provided, and an L-shaped plate 5 is fixedly connected to the outer side of the top of the steelmaking furnace body 1. When the molten steel solidifies inside the water outlet pipe 4, the screw 8 is first rotated, and the screw 8 rotates and moves inside the threaded tube 7.

Through the cooperation of the power box 17 and the wire 20, the heating coil 21 on the outside of the water outlet pipe 4 is started, and the molten steel remaining on the inner wall of the water outlet pipe 4 after being crushed inside the water outlet pipe 4 is thermally treated, thereby achieving the effect of preventing blockage. When the cleaning is completed, the extrusion rod 16 no longer squeezes the switch 18, and the power supply box 17 is automatically powered off under the action of the reset spring 19, thereby achieving the effect of saving energy.
