[0041] like Figure 4 As shown, the working principle of this scheme is:

[0042] The present invention provides a multi-interactive medium frequency furnace automatic slag scooping mechanism and control system, including a guide rail 1 and an industrial robot 2 installed on the guide rail 1, a coaxial slag scooping mechanism installed at the end of the industrial robot 2 and a high-temperature resistant slag scooping spoon 6 fixed on the coaxial slag scooping mechanism, the coaxial slag scooping mechanism has a built-in stepping motor for driving the slag scoop 6 to move; the heat insulation board 5 can effectively block the heat radiation from the high-temperature molten iron and protect the components inside the coaxial slag scooping mechanism; the slag scoop 6 is made of high-temperature resistant material, has extremely high flexural strength and high-temperature strength, and is in direct contact with the molten iron. It will not stick to the molten iron and can scoop out residues in the molten iron for a long time. The control system includes an operation panel 8, which has a built-in programmable controller to realize linkage control of various on-site equipment. The control system includes a computer-side host computer 16 and a mobile phone-side host computer 17. After the host computers establish communication with the industrial computer 14, they can process signals sent by various sensors to realize control of corresponding equipment in the system. The operator can control the slag scooping mechanism through physical buttons, host computer buttons, and voice interaction to avoid close-range operation by the operator, effectively reducing safety risks.

[0043] The industrial robot 2 of this solution adopts a six-axis industrial robot, which is installed on the guide rail 1. The industrial robot 2 can move on the guide rail 1 to expand the working radius of the industrial robot 2, while also taking into account the areas of two adjacent intermediate frequency furnaces 11; and according to the instructions issued by the operator, the industrial robot 2 can move on the guide rail 1 in the direction of the instructions, and then the industrial robot 2 performs a specific slag removal action;

[0044] The coaxial slag scooping mechanism 3 of the present scheme has a built-in stepper motor, and the entire coaxial slag scooping mechanism 3 is installed on the end flange of the industrial robot 2. When the industrial robot 2 moves to above the medium frequency furnace 11, the slag scooping spoon 6 opening program in the control system is triggered, and the program controls the slag scoop 6 of the coaxial slag scooping mechanism 3 to be in the open position. When the industrial robot 2 and the coaxial slag scooping mechanism 3 move to above the molten iron, the coaxial slag scooping mechanism 3 automatically starts the slag scooping operation, and then the coaxial slag scooping mechanism 3 is lifted to a safe height, and then moves with the industrial robot 2 to above the slag bucket 12. After that, the stepper motor of the coaxial slag scooping mechanism 3 repeatedly opens and closes the slag scoop 6 to remove the slag blocks and drop them into the slag bucket 12, thereby completing the slag scooping operation.

[0045] Usually, the industrial computer 14 is arranged in the control room, and the operation panel 8 is also installed in the control room. The operation panel 8 is controlled by PLC and is used to connect the industrial robot 2, the medium frequency furnace 11 and other on-site auxiliary equipment. The operator can remotely control the equipment of this scheme through the smart phone, and realize the linkage control of each device in the slag scooping mechanism through the built-in mobile phone program and voice control program of the smart phone; the slag scooping spoon 6 is made of high temperature resistant material, has extremely high bending strength and high temperature strength, is in direct contact with the molten iron, and can scoop the residue in the molten iron for a long time;

[0046] The control system of this solution has multiple startup methods: 1. Start button on the control panel; 2. Start button in the host computer program on the computer; 3. Start button of the host computer on the mobile phone; 4. Voice interaction program of the host computer on the mobile phone.

[0047] In summary, this solution implements remote control of industrial robots to perform slag scooping operations in a variety of interactive ways, solving the problem of high risk at the slag scooping site. The coaxial slag scooping mechanism 3 involved in this solution can reduce the amount of molten iron carried out. By arranging a stepper motor inside the coaxial slag scooping mechanism 3, the rotation angle of the stepper motor is controlled by the command sent by the control system, and the opening and closing of the slag scooping spoon 6 can be further controlled, so that the coaxial slag scooping mechanism 3 has a unique movement mode, which is different from the existing technology, so that it can scoop out the residue to the maximum extent.
