到目前为止,在钢水、铁水测温方法中,按测温敏感元件的特点区分,主要有两大类:一是间接测温,又称非接触式测温.即测温敏感元件在测温时与钢水、铁水不直接接触.如光学高温计、光电高温计、辐射高温计、比色高温计、红外高温计等等,都属于这一类型.二是直接测温,又称接触式测温,即测温敏感元件在测温时,与钢水、铁水直接接触.热电偶测温就属于这一类型.
So far, in the molten steel, hot metal temperature measurement method, according to the characteristics of temperature-sensitive components to distinguish, there are two main categories: First, indirect temperature measurement, also known as non-contact temperature measurement, temperature-sensing components in the temperature measurement Such as optical pyrometer, photoelectric pyrometer, radiation pyrometer, colorimetric pyrometer, infrared pyrometer, etc., belong to this type. Two is the direct temperature measurement, also known as contact measurement Temperature, temperature sensing element in the temperature measurement, and molten steel, hot metal in direct contact with the thermocouple temperature measurement are of this type.
