APPARATUS FOR CONTINUOUSLY MEASURING TEMPERATURE OF MOLTEN STEEL

摘要

PURPOSE: A temperature measuring device for consecutively measuring a temperature of molten steel is provided to reduce a steel processing time by consecutively measuring a temperature of molten steel. CONSTITUTION: A temperature measuring device(100) comprises a measuring sensor(120), a cable(110), and a protection unit(130). The measuring sensor measures a temperature. The cable is connected to the measuring sensor and transmits the temperature measured by the measuring sensor. The protection unit protects the measuring sensor and cable from heat by arranging the same in inside. When a measuring device is inserted into molten steel, the protection unit has other portions having a thicker thickness than a thickness of a portion where a slag layer contacts to. The protection unit is composed of a first refractory body-carbon compound and second refractory body.
