摘要:
激光热处理作为一种材料表面高温处理技术,具有升温速度快、温度范围宽的特点,升温速度可达104℃/s。传统的接触式测温法无法满足快速升温的温度场和升温过程的测量需求,为满足这一需求,本文设计一种非接触式的基于图像处理的红外CCD测量材料表面温度的方法。针对温度测量范围宽的问题,提出了分段测量的方法;针对升温速度快,提出了计算机控制的快速自适应曝光时间算法;为提高测量精度,对温度-灰度曲线进行了严格标定。实验证明该方法是一种低成本、高稳定性、高精度、简单有效的测温方法,本研究为激光热处理中材料表面温度测量提供了切实可行的解决方案。
Abstract:
Laser heat treatment is a high-temperature material-treatment technique that can heat rapidly and can work in a broad temperature range; it heats at a rate of up to 104℃/s. The traditional methods of measuring contact temperature cannot satisfy the measurement requirements of a rapid temperature-rising range and heating process. In this study, a noncontact image processing-based infrared CCD method was designed to measure the surface temperature of materials. Moreover, a method of segmented measurement was developed to solve the problem of the wide temperature measurement range. For the rapid heating rate, a computer-controlled fast adaptive exposure-time algorithm was proposed, and the temperature-grayscale curve was strictly calibrated to improve the measurement accuracy. The experimental results showed that the proposed method is a low-cost, high-stability, high-precision, simple, and effective temperature measurement technique. This paper presents a practical improvement technique for measuring the surface temperature of materials during the laser heat-treatment process.
