Equipment operating and process quality state monitoring system for high-speed rolling mill

Abstract

The invention discloses an equipment operating and process quality state monitoring system for a high-speed rolling mill, belonging to the technical field of high-speed wire rolling. Hardware comprises sensors for electric quantity, rotation speed and the like, a 4017+ intelligent data acquisition module, an RS485-RS232 communication conversion module and an industrial control computer. A rolling current signal, a rolling rotation speed signal and other signals are measured by the sensors, then subjected to A/D (Analog to Digital) conversion by the data acquisition module and then stored into the industrial control computer through the RS485-RS232 communication conversion module, the acquired data are issued to a network by utilizing an OPC (OLE (Object Linking and Embedding) for Process Control) protocol, and a user extracts the recorded information from an IE browser or a client side through the network for observing and analyzing. Software comprises an OPC communication module, an operation state real-time monitoring module, an alarm information recording and analyzing module, a trend information analyzing and processing module, a historical recall functional module and an industrial signal logic analysis module. The equipment operating and process quality state monitoring system has the advantages of improving the reliability for equipment operation, prolonging the service life and effectively lowering the cost.

Description

technical field [0001] The invention belongs to the technical field of high-speed wire rolling, and in particular provides an equipment operation and process quantity state monitoring system for high-speed wire rolling mills. Background technique [0002] High-speed wire rod mills are typical highly automated and mechanized equipment. Once a sudden failure occurs, it will seriously threaten normal production and cause huge losses. Due to the influence of equipment function, accuracy and reliability, the output and accuracy of wire rod products are also affected, and the indicators such as machine-hour output and finished product rate are unstable; equipment failures in turn affect the production rhythm. In order to ensure the completion of output tasks, it is inevitable that there will be periodic The overload production of the equipment has a greater impact on the equipment status, function and precision, thus forming a vicious circle. What's more, unbalanced production wi...

Problems solved by technology

However, the statistics of the production process of high-speed wire rolling does not match the installed capacity of wire rods, which is a problem that must be paid attention to in the development of the wire rod industry today. Many steel mills lack effective monitoring and management methods for the production process process
