[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-5 This utility model is a high-efficiency bottom-blowing argon device for an electric furnace, including a furnace body 1; the furnace body 1 has a cavity 2 inside, and a blowing assembly is snapped onto the bottom of the furnace body 1; the blowing assembly includes a brick seat 8, a permeable brick body 18 is fixedly connected inside the brick seat 8, an adjusting plate 2 10 is fixedly connected to the top of the permeable brick body 18, an air hole 19 is opened on the upper surface of the adjusting plate 2 10, a pipe 7 is connected to the bottom of the permeable brick body 18, and the end of the pipe 7 is connected to an external air source, an adjusting assembly is rotatably arranged inside the brick seat 8 to cooperate with the permeable brick body 18, the adjusting assembly includes an adjusting plate 1 9 that rotates on the permeable brick body 18, an air hole 19 is opened on the upper surface of the adjusting plate 1 9 to cooperate with the adjusting plate 2 10, a sliding groove 15 is opened at the bottom of the brick seat 8, a connecting rod 14 that slides inside the sliding groove 15 is fixedly connected to the bottom of the adjusting plate 1 9, and a limit ring 16 is threadedly connected to the end of the connecting rod 14.

[0025] An external gas source is connected to pipeline 7 to blow argon gas into the permeable brick body 18. The argon gas is blown into the cavity 2 inside the furnace body 1 through the air holes 19 of the second regulating plate 10 on the top of the permeable brick body 18. The connecting rod 14 is moved to make the first regulating plate 9 on the top of the second regulating plate 10 rotate. During the rotation, the first regulating plate 9 blocks the air holes 19 on the surface of the second regulating plate 10, so as to adjust the size of the air holes 19 on the surface of the second regulating plate 10. When the position of the first regulating plate 9 is appropriate, the rotating limiting ring 16 fixes the connecting rod 14. The size of the hole directly affects the flow rate and flow velocity of the gas through the permeable brick. A smaller hole diameter increases the gas flow resistance and reduces the flow rate; a larger hole diameter reduces the resistance and increases the flow rate, thereby controlling the stirring intensity of the molten steel.

[0026] Please see Figures 1-5The outer wall of the brick base 8 has grooves 311 on both sides. A limit block 13 is slidably installed inside the groove 311. A spring 12 is fixedly connected inside the groove 311. The other end of the spring 12 is fixedly connected to one side of the limit block 13. The inner sides of the furnace body 1 have grooves 14 that cooperate with the limit block 13. The outer wall of the furnace body 1 has grooves 25 that communicate with grooves 14. A screw 6 that cooperates with the limit block 13 is threadedly connected inside grooves 25.

[0027] When installing the brick base 8, the limiting block 13 enters the interior of the second groove 5 along the first groove 4 to limit the brick base 8. When the limiting block 13 moves inside the first groove 4, it compresses the spring 12 to generate elastic potential energy, pushing the limiting block 13 into the interior of the second groove 5. When it is necessary to disassemble the brick base 8, simply rotate the screw 6 on the outer wall of the furnace body 1. The screw 6 moves in a straight line along the second groove 5 to push the limiting block 13 to retract. When the limiting block 13 retracts into the interior of the third groove 11, the brick base 8 can be pulled out to complete the disassembly.

[0028] Please see Figure 3 The groove 4 is trapezoidal in shape, and the inclined surface of the trapezoid contacts one end of the limiting block 13.

[0029] By designing the groove 4 to be trapezoidal, the inclined surface of the trapezoid forms a push against the limiting block 13, enabling it to retract.

[0030] The operation process of this embodiment is as follows: When installing the brick base 8, the limiting block 13 enters the interior of the second groove 5 along the first groove 4 to limit the brick base 8. When the limiting block 13 moves inside the first groove 4, it compresses the spring 12 to generate elastic potential energy, pushing the limiting block 13 into the interior of the second groove 5. When it is necessary to disassemble the brick base 8, simply rotate the screw 6 on the outer wall of the furnace body 1. The screw 6 moves linearly along the second groove 5 to push the limiting block 13 to retract. When the limiting block 13 retracts into the interior of the third groove 11, the brick base 8 can be pulled out to complete the disassembly. Connect the external air source and the pipeline 7. Argon gas is blown into the permeable brick body 18. The argon gas enters the cavity 2 inside the furnace body 1 through the air holes 19 of the second adjusting plate 10 on the top of the permeable brick body 18. The connecting rod 14 is moved to make the first adjusting plate 9 on the top of the second adjusting plate 10 rotate. During the rotation, the first adjusting plate 9 blocks the air holes 19 on the surface of the second adjusting plate 10, so as to adjust the size of the air holes 19 on the surface of the second adjusting plate 10. When the position of the first adjusting plate 9 is appropriate, the rotating limiting ring 16 fixes the connecting rod 14. The size of the hole directly affects the flow rate and flow velocity of the gas through the permeable brick. A smaller hole diameter increases the gas flow resistance and reduces the flow rate; a larger hole diameter reduces the resistance and increases the flow rate, thereby controlling the stirring intensity of the molten steel.
