氮气保护推板炉自控系统的设计与实现

基于锂电池止极材料烧结曲线和T艺参数等特点，提出应用可编程逻辑控制器（PLC）对氮气保护推板炉的温度、气氛和循环动作实现自动控制。同时用VB语言设计了可以设置控制参数、显示和存储测控数据的计算机控制软件。指出自动控制系统应该是结合工艺，集控制、管理和数据处理功能于一体的系统。现场运行表明该系统稳定可靠，达到设计要求。

Design and Implementation of Automatic Control System of Nitrogen-protected Push Type Kiln

Based on the characteristics of the sinter curve and technique process of positive pole material in lithium battery, the application of programmable logic controller is proposed to implement automatic control for temperature, atmosphere and circulation of nitrogen-protected push type kilns, Meanwhile, the computerized control software that can set up control parameters, display and store measured data is designed by using VB language, It is pointed that the automatic control system should be an integrated system combining techniques, control function, management function and data processing function. The locale circulation shows that the system is steady and it achieves design requirement.
