Ring Rolling Mill

Large –scale aluminum ring rolling mill is the core of ring rolling ,it is required for automatic control system to realize high precision and fast response.Based on the configuration of the equipment, characteristics of ring rolling and the process flow of production, the paper not only studied the Control principle of the automatic control system but also designed the control scheme of software and hardware. The core of system is PLC. The system can effectively control hydraulic system, measurement system, feeding servo system by the cooperation of PLC and human machine interface (HMI). It realized fully automatic operation under the ring rolling mill close-loop control. The high precision control and safe operation can be realized by using multi network communication technology and advanced full AC drive system .The rolling quality of rings is high. The design accords with the control logic requirements of rolling process control. The control system is smooth and reliable.

Regarding high precision and automatic control requirements for management and control system of oil depot, this paper applied RF technology in in-out oil management and automatic control theory in automatic control system of oil depot. Thus, a novel oil depot automatic in-out control system based on three level structure and RF technology was designed. In the system, the three level structures are composed of on-site control level, site management level and remote management level. A mode of combining control instruments with PLC controller was adopted in on-site control level and VB .Net was used as software for upper computer. The designed non-contact IC card management software for oil access and in-out oil control system will simplify the operation process of employees; approve levels of safe management and data accuracy for oil access in oil depot. Field tests show that this system has advantage of high control accuracy achieved 0.2 magnitude, high precision of data acquisition and easy operation for control management. The system provides an efficient technology approach for raising the level of automation and management in the oil industry.
