PURPOSE:To make measurement of the O2 partial pressure of a molten metal layer, molten slag layer or gaseous layer and drawing of a sample simultaneously so that the in-furnace reaction is recognized overall by inserting a probe provided with a lower level measuring part and upper level measuring part perpendicularly into a converter and positioning both the measuring parts to the molten metal, molten slag or the gaseous layer above the same. CONSTITUTION:The probe 1 which is provided with the lower level measuring part 2 constituted of an insert 4 contg. a thermocouple and oxygen concn. cell and a vacuum pin sampler 5 and the upper level measuring part 3 consisting of a sampler 7 having an inflow port 6 for the molten slag and gas and an oxygen concn. cell 8 provided therein apart at a specific spacing l from each other is inserted perpendicularly into the converter. The lower level measuring part 2 is positioned into the molten metal A, the upper level measuring part 3 into the molten slag B or the lower level measuring part 2 is positioned into the molten slag B and the upper level measuring part 3 into the gaseous layer C. The measurement of the O2 partial pressure in the respective layers and the drawing of the sample are simultaneously executable. The association of the chemical reactions in the respective layers in the furnace changing momentarily is thereby known and efficient converter operation is carried out. |
