过去,国内外多以快速热电偶点测出铁槽处的铁水温度,以此作为考核炉况的依据。但点测用的快速偶为一次性消耗品,而且当测温间隔较短、点测频繁时,补偿导线温度往往升至100℃以上,超出其补偿温度范围,使指示温度低于实际温度,引起附加误差。故目前连续测温的使用在日益增加。连续测温是将热电偶埋入冲天炉前炉或过桥内进行测量的一种方法。过桥连测虽能灵敏地反映炉况,但对测温装置要求较高(铁水温度高,对保护套管冲刷严重),在生产上使用不多。而常用前炉连测。连测比点测有较大的
In the past, at home and abroad to quickly measure the temperature of the hot metal at the hot metal temperature, as the basis for assessment of furnace conditions. However, with the rapid measurement of even a one-time consumables, and when the temperature measurement interval is short, frequently measured points, the compensation wire temperature tends to rise above 100 ℃, beyond the compensation temperature range, so that the indicated temperature is lower than the actual temperature, Caused additional error. Therefore, the continuous use of temperature measurement is increasing. Continuous temperature measurement is a method of measuring thermocouples embedded in a cupola furnace or bridge. Although the bridge can be measured even sensitive to reflect the furnace conditions, but the higher temperature measurement device (hot metal temperature, the protection of the casing erosion serious), not much use in the production. The common test before the furnace. Even test than the measured point larger
