一、前言温度的反复循环,即热疲劳,在许多生产过程中是引起构件损坏的主要原因,如各种热作模具。因此,许多生产和研究部门,常需进行一定数量的热疲劳实验,用以研究或评价材料。本文介绍的简易热疲劳炉温自动控制装置,其特点是简单、实用、性能可靠,几乎对所有的研究部门,都可利用原有仪器组装一台;另外,该设备性能比较齐全,其升降温速度,上下限温度和上限保温时间,在一定的范围内都连续可调,使用起来十分方便。二、工作原理如使用的是一台XCT-101二位控温仪表,应再配置一套同样的感应线圈L′_3、信 First, the introduction of the cycle of temperature, that is, thermal fatigue, in many production processes is the main cause of component damage, such as a variety of hot die. As a result, many production and research departments often require a certain amount of thermal fatigue tests to study or evaluate materials. This article describes the simple automatic thermal fatigue temperature control device, which is characterized by simple, practical, reliable performance, almost all of the research department, the original instrument can be used to assemble a; In addition, the performance of the device is relatively complete, the cooling temperature Speed, the upper and lower temperature and the upper holding time, in a certain range are continuously adjustable, very convenient to use. Second, the working principle If you are using a XCT-101 two temperature control instruments, should be configured with a set of the same induction coil L’_3, letter
