Problems solved by technology

However, because the environment in the smelting room is very harsh, and the furnace tube is manually placed on the smelting flat car by a crane, even if the flat car can be positioned accurately, the furnace tube may not be in the center position, and some current laser or photoelectric positioning methods It cannot be used here, so we designed a method that can be used in harsh environments and can accurately position the furnace drum

Embodiment Construction

[0019] Take the 3000KVA ferroalloy refining furnace as an example:

[0020] 1. The absolute value encoder sensor 9080 series of German Turck company with Profibus bus is selected, which has a good reputation in metallurgical enterprises;

[0021] 2. The control system adopts simens s7-314-2dp, and the DP coupler is used to connect with the absolute encoder;

[0022] 3. When the diameter of the furnace cylinder is 2 meters, if the position of the furnace cylinder positioning sense does not rotate, the proximity switch can accurately measure the longitudinal position of the furnace cylinder. The vertical deviation between the rod and the rail is only about 20mm, so as long as the operator lifts it according to the regulations, it can be guaranteed that the sensing rod can be within the effective range of the proximity switch;

[0023] 4. Install a calibration sensor pair in the refining area. When the flat car passes by here, the center distance of the flat car will be auto...

Abstract

The invention provides a method for automatic positioning of a smelting flat cart. The invention studies positioning systems in complicated smelting environments, and on the basis the invention provides an automatic positioning system adapted to current technical equipment and satisfying requirements of technique automation. Firstly, an induction rod suitable for furnace cylinder positioning is designed, and then a proximity switch is installed on each of two sides of a flat cart track. Through cooperation with an absolute value encoder, a furnace cylinder on a flat cart can be positioned precisely.

Description

technical field [0001] The invention is applied to automatic position control of mobile smelting flat cars in ferroalloy enterprises. Background technique [0002] Ferroalloy enterprises that smelt outside the furnace generally use a mobile flat car to transport the smelting furnace barrel, put the pre-made furnace barrel on the smelting flat car with a crane, and lift it away with a crane after smelting. Due to the harsh environment of the smelting furnace and the large amount of smoke and dust after the combustion reaction, it is not easy to see the position of the furnace barrel in the control room, and it is very dangerous to go in and get close to it. Therefore, it is necessary to automatically position the smelting flat car, and the flat car Automatic positioning is also an important part of realizing automatic smelting. However, because the environment in the smelting room is very harsh, and the furnace tube is manually placed on the smelting flat car by a crane, eve...
