摘　　要：在冶炼等工业的生产过程中,热处理是决定锻件质量的重要步骤。工件淬火时温度过高会导致工件损坏,淬火时温度过低不足以消除工件成分中的应力,容易造成工件硬度不够。热处理炉是重要的工业冶炼设备,具有温度范围大、炉温控制严格等特点,热处理炉的温度控制一直是工业锻造、冶炼的重点的难点,炉温的调整会直接影响部件的质量。从热处理炉的运行入手分析,综合探讨了单片机的功能以及工作原理,提出了一种基于单片机的热处理炉温度PID控制系统设计方法,从软硬件开发角度详细介绍了温度控制系统的模块设置以及控制算法选择,使热处理炉炉温控制更加智能化,能够最大限度的提升工业热处理炉的温度控制精准度,为工业热处理的智能化和自动化发展提供参考性建议。In the production process of smelting and other industries,heat treatment is an important step to determine the quality of forging.Workpiece quenching temperature is too high will lead to workpiece damage,quenching temperature is too low is not enough to eliminate the stress in the workpiece composition,easy to cause the workpiece hardness is not enough.Heat treatment furnace is an important industrial smelting equipment,with a large temperature range,strict temperature control and other characteristics,the temperature control of heat treatment furnace has always been the key and difficult point of industrial forging and smelting,the adjustment of furnace temperature will directly affect the quality of components.It analyzes the operation of heat treatment furnace,comprehensively discusses the function and working principle of single chip microcomputer,proposes a design method of PID control system of heat treatment furnace temperature based on single chip microcomputer,and introduces the module setting and control algorithm selection of temperature control system in detail from the perspective of software and hardware development,so as to make the temperature control of heat treatment furnace more intelligent.It can maximize the temperature control accuracy of industrial heat treatment furnace,and provide reference suggestions for the intelligent and automatic development of industrial heat treatment.
