Embodiment Construction

[0013] In the galvanizing production process, the annealing furnace section is a very important link. Due to factors such as the material of the strip steel and the temperature in the furnace, when the strip steel runs in the annealing furnace, it often deviates, and the edge of the strip steel is hung in the furnace. Cracks, resulting in broken belts in the furnace. Therefore, in the traditional technology, a deviation correction detection device is specially configured in the annealing furnace section. However, in the original design program of the traditional technology, the unit is not considered to automatically reduce the speed of the unit when the strip is seriously deviated, and the strip is still running at high speed. When the operator finds out, the edge of the steel strip is often cracked or even broken, causing the unit to stop passively, which has a great impact on production and operation, and produces a large amount of waste and defective products. In order to ...

Abstract

The invention relates to an automatic control technology in the smelting field, and discloses a control method capable of preventing strip steel of a galvanizing unit from deflection and belt braking in operation. The problems that in the prior art, the galvanizing unit still runs at a high speed after the strip steel is deflected, therefore, the strip steel is easily broken, a large number of waste products and a large number of inferior-quality products are produced due to machine halt of the galvanizing unit, and serious damage is caused to a device are solved. The method includes a first step of collecting deflection data of the current running strip steel through a deflection correcting detection device, and transmitting the deflection data to a control unit; a second step of enabling the control unit to compare the deflection data with a preset deflection threshold limit value, and controlling the galvanizing unit to conduct speed reducing running if the deflection data are larger than or equal to the deflection threshold limit value; controlling the galvanizing unit to continuously run at the current speed if the deflection data are smaller than the deflection threshold limit value. The control method capable of preventing the strip steel of the galvanizing unit from the deflection and the belt braking in the operation is suitable for automatic control of the galvanizing unit in smelting.

Description

technical field [0001] The invention relates to an automatic control technology in the field of smelting, in particular to a control method for preventing strip deviation and broken strips in a galvanizing unit. Background technique [0002] The complexity of the galvanizing production process determines that the galvanizing unit has many equipments, long lines, continuous production and cannot be shut down. Once shut down, a large amount of waste and defective products will be generated, a large amount of raw materials will be consumed, and production costs will be increased. Due to the long line, the length of the strip running between the uncoiler and the coiler is more than 2,000 meters. Therefore, in order to ensure that the operation of the strip steel does not deviate too much from the axis of the unit, and to reduce the occurrence of strip sideband defects and broken strips, in the traditional technology, after the uncoiler, at the entrance looper, at the end of the ...
