Metallurgical production enterprise adopts computer for automatic control and management. Automatic control during metallurgical production process includes the control on main production process such as smelting, casting and rolled metaletc.and the control on auxilliary production process such ass water supply, electricity, heat, oxygen and gas etc. Modern metallurigical enterprise adopts computer to integrate production process control and production management, thus largely improves automation degree. Metallurgical automation could largely increase labor productivity and product quality, reduce circulating fund occupation and improve labor condition thus obtain high economic benefits.
Production Management system of metallurgical enterprise is composed by central computer,several process management computer, several hundreds of imput/output terminal and communication system. Most of the terminal devices are placed in various links of the whole production process. This kind of computer production management infromation system could timely reflect various changes during overalll production process. Therefore, actual situation and data of the whole production could be obtained through computer query. Reversely, the production of the whole metullurgical plant could controlled through the computer's statistic analysis, logical judgement mathematical model calculation and the command from management personnel. Its main function include: controlling product contract, making production plan and operation plan, mastering capital balance and flow as wellas equipment running and spare parts inventory, and executing optimum management on production.
Metallurgical automation have further development toward integration, intellectualization and optimization of management, monitoring and control. For example, computer has been applied for unmanned operation and management of stacking and material taking of spare parts warehouse and slabs. Operating status of mechanical equipment and electrical equipment aslof starts adopting computer for automatic diagnosis; if there is any equipment fault, except for automatically ananlyze fault property and location, it also could automatically switch and start stanbby devices to ensure equipment running in good condition. Development tendency of metallurgical automation is to compose a control system from part to entirety, integrating a perfect entirety from production plan, stock preparation to the whole production process.
