随着对造型线生产率及铸件质量要求的提高，对型砂性能的在线检测及控制提出了更高的要求，而计算机应用技术及机电一体化技术的飞速发展，使得实施在线检测－控制型砂性能成为可能。基于此，研究与开发型砂在线控制仪在国际上也是铸造技术的前沿课题之一。通过理论研究与实验验证，证明了本研究所指的一套型砂性能自动控制系统，具有良好的重复性和可靠性，用其可实现型砂性能的在线检测与控制。
With the improvement of molding line productivity and casting quality requirements, higher requirements are put forward for the on-line inspection and control of molding sand performance. The rapid development of computer application technology and mechatronic technology has made it possible to implement on-line inspection and control of sand performance may. Based on this, the research and development of in-line controller for sand is also one of the leading issues in the field of foundry technology in the world. Through the theoretical research and experimental verification, it proves that the system is an automatic control system for the performance of sand, which has good repeatability and reliability. It can realize the on-line detection and control of sand performance.
