An online quality alarm method for wire rod cooling process

Abstract

The invention relates to a wire controlled cooling process on-line quality alarming method. Logical judgment is added into a second level system L2, a segment of program is added, particularly, the field with wrong information in an MES database is received, and an L2 program automatically activates a WAV alarming audio frequency. If the field with the wrong information in the database is a blank, the field shows that the WAV alarming audio frequency is not activated, and thus an operator can master the product quality change condition after spinning in real time during production. According to the wire controlled cooling process on-line quality alarming method, real-time monitoring is conducted on on-line products, the whole course control ability of the operator to the air cooling line product quality is improved, the reasons for quality risks of the products are understood, the product quality is promoted, quality scrapping caused by process parameter change is prevented, and batch scrapping is avoided completely.

Description

technical field [0001] The invention relates to an on-line quality alarm method for a cooling process that is automatically judged by a system. Background technique [0002] After the wire is spun by the laying machine to form a coil, it needs to be cooled by the air-cooled roller table, and finally the coil is formed. In this process, the temperature and humidity of the environment, the opening degree of the fan, the number of openings of the insulation cover, and the speed of the roller table, once any factor changes, will have a serious impact on the quality of the product. Different steel types will be adjusted, but the coil situation cannot be grasped in real time during the normal production process. At present, the following problems exist in the wire rod cooling process: [0003] (1) The operator cannot control the process situation after spinning in real time. [0004] (2) Products that do not meet the process cannot be found in time, resulting in batch scrapping....

Problems solved by technology

In this process, the temperature and humidity of the environment, the opening degree of the fan, the number of openings of the heat preservation cover, and the speed of the roller table, once any factor changes, will have a serious impact on the quality of the product. At present, the operators follow the process requirements. Different steel types will be adjusted, but the coil situation cannot be grasped in real time during the normal production process. At present, the following problems exist in the wire rod cooling process:

[0003] (1) The operator cannot control the process situation after spinning in real time

[0004] (2) Products that do not meet the process cannot be found in time, resulting in batch scrapping
