Abstract
The utility model relates to a converter auxiliary gun composite probe temperature-measuring oxygen-determining component, which comprises a ceramic head (1), a temperature sensor (2), a zirconia pipe (4) and outer electrodes (3) of the zirconia pipe (4), wherein the temperature sensor (2) and the zirconia pipe (4) are arranged on the ceramic head (1). The utility model is characterized in that the outer part of the zirconia pipe (4) is sheathed with a section of high temperature resistance protective pipe (5) which is fixed on the ceramic head (1); the inner hole diameter of the high temperature resistance protective pipe (5) is matched with the diameter clearance of the zirconia pipe (4); the end part of the zirconia pipe (4) penetrates out from the front end of the high temperature resistance protective pipe (5) to be exposed. Since the strength of a quartz glass pipe is higher than that of the zirconia pipe (4) and only the front end of the zirconia pipe (4) penetrates out from the high temperature resistance protective pipe (5) to be exposed, the utility model can well protect the zirconia pipe (4). The utility model stops the phenomenon of the fracture of the zirconia pipe (4) from occurring. The comprehensive measuring success rate of the utility model can reach over 96 percent shown by a great amount of trials.

Summary of the invention
The purpose of this utility model is to provide a kind of and improve the comprehensive revolving furnace sublance combined probe thermometric of surveying into rate and decide the oxygen parts for overcoming the deficiencies in the prior art.
The utility model purpose reaches by following technical solution: a kind of revolving furnace sublance combined probe thermometric is decided the oxygen parts; comprise ceramic head and be located at temperature sensor, tubular zirconium-oxide and outer electrode thereof on the ceramic head; it is characterized in that: described tubular zirconium-oxide is arranged with one section high temperature resistant protective tube outward; described high temperature resistant protective tube is fixed on the ceramic head; high temperature resistant protective tube internal orifice dimension cooperates with the tubular zirconium-oxide diametric clearance; the tubular zirconium-oxide end passes from high temperature resistant protective tube front end exposes, and wherein can be quartz glass tube, vitrified pipe or nickelalloy pipe.
Further be provided with as the utility model purpose: described ceramic head aft end face is provided with the die cavity of an indent; described ceramic head front end face be provided with cross-sectional shape respectively with temperature sensor, high temperature resistant protective tube and outer electrode matches and be communicated with die cavity three jacks are installed; temperature sensor, high temperature resistant protective tube and outer electrode thereof are plugged in three respectively and install in the jack; the signal lead of temperature sensor, tubular zirconium-oxide and outer electrode thereof is connected on the wiring board and by lead and causes outside the die cavity, and wiring board places die cavity and sealed admittedly by high-temperature cement.
Compared with prior art; the beneficial effects of the utility model are: because quartz glass tube has the intensity more much higher than tubular zirconium-oxide; tubular zirconium-oxide only front end therefrom passes and exposes; therefore can protect tubular zirconium-oxide well; stopped the phenomenon of tubular zirconium-oxide generation fracture; by a large amount of demonstrations on probation; comprehensively surveying into rate can reach more than 96%; in addition, the revolving furnace sublance combined probe thermometric of above-mentioned further setting is decided the oxygen block construction and is also had the more advantage at the end of cost simple in structure, easy to assembly.
