一前言温度是炼铜过程的很重要的一个控制参数,过去我们都是用光学高温计进行间断测温,误差较大,且不能发出连续信号,我们曾经试验过用红外线测温器对铜液温度作非接触式的连续测量,但因环境太差,除了灰尘之外,主要是CO,CO_2及H_2O蒸汽对红外波段有吸收而产生不规则误差,因而在目前条件下不宜使用。用热电偶作接触式连续测量也作过一些试验,主要问题是没有适当的保护套管,因而一直未能解决,例如我们曾用多种材料的套管作试验(如用不锈钢、高级
Preface Temperature is a very important control parameter of copper refining process. In the past, we all used the optical pyrometer to conduct intermittent temperature measurement with large error and could not send continuous signal. We have tested the use of infrared thermometer for copper liquid Non-contact continuous temperature measurement, but because the environment is too bad, in addition to dust, mainly CO, CO_2 and H_2O steam absorption of the infrared band has an irregular error, and therefore should not be used under current conditions. There have also been some experiments with thermocouples for continuous contact measurement. The main problem is that there is no solution to this problem. For example, we have experimented with various materials such as stainless steel,
