Problems solved by technology
[0004] 1. At present, smelting converters are usually driven by AC winding motors. However, AC winding motors not only have poor speed regulation performance, but also poor controllability and high energy consumption. Therefore, high-precision speed regulation and control cannot be achieved. Currently, they can only be operated manually. , the operation is difficult and cannot be positioned accurately, which seriously affects the production capacity and even causes safety accidents
[0005] 2. At present, the smelting converter uses an electromechanical position switch to detect the position of the converter, but this electromechanical position switch has poor precision and poor reliability, so it is difficult to put it into normal operation for a long time, and it can only be positioned manually by the operator, which has serious safety hazards Hidden danger
In actual work, there have been many accidents of pouring high-temperature melt into the workshop, which not only caused damage to equipment, but also caused economic losses, and more seriously, casualties

The invention provides smelting converter control equipment, which comprises a converter, a variable-frequency speed-adjusting alternating-current asynchronous motor and speed reducer, a converter position detection device, a melt ladle liquid level detection device, a melt ladle position detection device and a control device. The converter comprises a body, transmission gears or rollers are arranged on the converter body, the converter position detection device is used for detecting tilting positions of the converter, the melt ladle liquid level detection device is used for detecting the height of liquid level of a melt ladle, and the melt ladle position detection device is used for detecting positions of the melt ladle. When the melt ladle position detection device detects that the meltladle is positioned at a preset position and the melt ladle liquid level detection device detects that the liquid level in the melt ladle does not reach a preset height, the control device is used for controlling the converter to tilt through the variable-frequency speed-adjusting alternating-current asynchronous motor and speed reducer.. High efficiency, safety, high precision and high reliability in automatic operation of the smelting converter control equipment can be realized.
Description
Technical field [0001] The invention relates to the technical field of metallurgy, in particular to a smelting converter control device. Background technique [0002] Converter smelting is one of the most commonly used smelting methods for non-ferrous metal smelting. The furnace body of the converter is cylindrical, and the inner lining is made of refractory materials. It is heated by chemical reaction heat during the blowing process and does not require an external heating source. It is an important equipment for smelting non-ferrous metals such as copper and nickel. [0003] The current electric drive and control technology of smelting converter has the following defects: [0004] 1. At present, smelting converters usually use AC winding motors to drive, but AC winding motors not only have poor speed regulation performance, but also have poor controllability and high energy consumption. Therefore, high-precision speed regulation and control cannot be achieved. Currently, they can ...
