 铜熔炼过程中熔体温度是一个重要参数，温度过低，反应无法正常进行，温度过高会浪费能源，降低炉寿命，所以熔体温度在线检测成为实现生产过程自动控制的关键。但是目前国内转炉吹炼绝大多数没有温度在线检测的手段，基本上处于凭经验操作的落后状况，这主要由于冶炼生产的环境恶劣(高温辐射、高粉尘、腐蚀性气体、杂光干扰)造成的，如果使用热电偶接触法测温，由于熔体腐蚀性很强，在铜熔炼中难以实现长时间温度检测，而且转炉过程中炉体会经常转动，熔体处于强烈翻动状态，所以应用接触法测熔体温度非常困难。非接触法测温具有充分的灵活性，现在应用较多的仪表———辐射温度计，是根据物体的辐射强度与温度的函数关系来标定温度值。但由于辐射强度受辐射系数影响，必须要根据辐射系数来修正测量值才能接近真实温度，这种修正不仅在技术上存在很多困难，现场也只能根据经验判断，修正中难免引入人为误差。此外,由于在铜冶炼中烟尘、大气、杂光等介质对辐射能的影响很大，使所测温度偏低，很难进行修正。因而，在铜冶炼中要想简便而准确地测定物体的温度是比较困难的。为此，我们通过大量实验与研究，开发出运用比值测温法的熔体自动测温装置。
