Abstract

A molten steel monitoring oxygen probe comprises the following units: a plastic support provided with two vertical through holes, wherein the outer periphery is provided with a plurality of buckles, the central portion extends upwards so as to form the vertical support, and a fixed hole is formed on the vertical support top end; a steel-made outer protection barrel with a bottom opening, wherein the protection barrel comprises a slender barrel, a thick barrel and a horizontal connecting portion, a conical top cover is formed on the slender barrel top, and a flange is formed on the thick barrelbottom; a steel-made inner protection barrel with a bottom opening and arranged in the outer protection barrel, wherein a conical top cover is formed on the inner protection barrel top, and the bottom outer periphery expands to form a platform; the platform inner side wall is provided with a plurality of buckle holes, and the buckles are buckled in the corresponding buckle holes one by one; the platform is clamped and fixed between the flange and the horizontal connecting portion; the probe also comprises a U-type quartz tube; top ends of two metal wires respectively go upward and penetrate one pin of the U-type quartz tube, and are connected in the bending portion; one U-type quartz tube pin is sleeved in a fixed hole; the probe also comprises a resin pre-coated sand rod in cladding moulding. The molten steel monitoring oxygen probe can easily penetrate steel slag.

Description

technical field [0001] The invention relates to the technical field of sensors in the smelting industry, in particular to a molten steel oxygen determination probe in the smelting industry. Background technique [0002] The oxygen-fixing probe is mainly composed of an oxygen-fixing sand head and a paper tube. It is mainly used in the steelmaking process of the smelting industry to measure the temperature and oxygen content of molten steel. Control plays an important guiding role. It is a must in the smelting process of major steelmaking plants, and it is a one-time consumable. Each furnace of molten steel must be measured many times by this product to complete the requirements for steelmaking. . When in use, put a 1.2-meter-long paper tube on the oxygen-fixing sand head, connect the special industrial PC oxygen meter to the oxygen-fixing gun, then insert the front end of the oxygen-fixing gun into the paper tube and plug it into the oxygen-fixing sand head, and put the oxyg...
