Based On The PLC Of The Car Type Heat Treatment Furnace Burning Gas Control System Research And Design

Car type heat treatment furnace burning gas to product equipment and pressure vessels after welding stress annealing temperature and volume before heating is given priority to; Hot coil, hot pressing molding before heat treatment and hot school and artifacts of normalizing is complementary.This thesis is divided into five chapters. The first chapter Outlines the development process of heat treatment furnace, the significance of automatic control system for heat treatment furnace; The second chapter introduces the composition and working principle of programmable controller, development and application areas, and explains some problems that should be paid attention to in use in the engineering design of PLC; The third chapter describes the production technology and process control requirements, discusses the detection and control system of the overall structure and process design, analyzes the main detection and control equipment selection, and the equipment selection were discussed; The fourth chapter analyzes the main functions of the control system, this paper introduces the selection of the control strategy, and discusses the control strategy in the Step7 software implementation; Fifth chapter briefly introduces the Win CC program outline design, details the total frame and various molecular functions and operating characteristics of the picture.
