炉前测温技术是近代发展起来的一种铸造测试技术,现已得到广泛应用。从目前我国铁路机车车辆工业系统常用炉前测温仪的种类及应用现状看,炉前测温仪按其测量方式分为接触式和非接触式两类。其基本结构由温度传感器和测量、显示、记录仪表等组成。一、钢水及铁水的温度测量钢水及铁水温度的测量方式有两种,即炉内(或浇包内)测温和炉外测温。在炉内测温时,一般采用浸入式热电偶高温计进行间断测温;炉外测温时,可用光学高温计进行间接测
Furnace temperature measurement technology developed in recent years as a casting test technology, has now been widely used. At present, the types and application status of commonly used furnace thermometers in China’s railway rolling stock industrial system are divided into two types: contact type and non-contact type. The basic structure of the temperature sensor and measurement, display, recording instruments and other components. First, the temperature measurement of molten steel and hot metal There are two ways to measure the temperature of molten steel and molten iron, that is, inside the furnace (or ladle) temperature and temperature outside the furnace. Temperature measurement in the furnace, the general use of immersion thermocouple pyrometer intermittent temperature measurement; outside the furnace temperature, the optical pyrometer indirect measurement
