Embodiment

[0021] A converter oxygen lance, refer to figure 1 with figure 2 , including a gun body 1, on which a fixed ring 2 and a detection ring 3 are sheathed. The fixed ring 2 is in interference fit with the gun body 1 , the detection ring 3 is in clearance fit with the gun body 1 , and the detection ring 3 is fixed under the fixed ring 2 . During the use of the oxygen lance, the lifting and fixing of the oxygen lance is realized by the lifting trolley, and the detection ring 3 and the lifting trolley are fixed, which reduces the impact on the detection ring 3 when the gun body 1 is tilted. Several support rods can be arranged between the lifting trolley and the lower end surface of the detection ring 3, and the two ends of the support rods are fixed with the lifting trolley and the detection ring 3 screws respectively. In order to reduce the damage to the fixed ring 2 caused by the temperature of the gun body 1 during operation, the inner wall of the fixed ring 2 is provided with...

Abstract

The invention discloses a converter oxygen lance. The converter oxygen lance comprises a lance body which is sleeved with a fixed ring and a detection ring, the detection ring is located below the fixed ring, the fixed ring and the lance body are in interference fit, the detection ring and the lance body are in gap fit, the detection ring is fixedly connected with a lifting trolley used for fixingthe lance body, multiple detection devices are arranged between the fixed ring and the detection ring, any detection device comprises a gravity ball, a displacement sensor and a displayer, all the gravity balls and the lower surface of the fixed ring are connected through ball hinges, the distance between the gravity balls and the upper surface of the detection ring are the same, all the displacement sensors are correspondingly arranged on the orthographic projection points of the gravity balls on the detection ring, and the distance between the gravity balls and the detection ring is monitored; the displayer electrically connected with the displacement sensors is arranged on the lance body. The lance has the effect of conveniently judging whethre the oxygen lance inclines or not

Description

technical field [0001] The invention relates to a converter oxygen lance. Background technique [0002] Oxygen lance is one of the main process equipment in oxygen converter steelmaking. The oxygen lance connected with the oxygen supply pipeline in the workshop is sent into the furnace by the lifting trolley, and the oxygen is sprayed to the furnace at a certain height from the surface of the metal molten pool. Liquid metal to realize the smelting reaction of the metal bath. Since the oxygen lance must be raised and lowered strictly along the vertical line during the blowing process, the lance head is sprayed towards the molten metal pool. However, in actual use, whether the oxygen lance moves along the vertical line during lifting and working cannot be intuitively detected whether the oxygen lance is tilted, so that it is inconvenient for the operator to judge whether the oxygen lance is tilted. Contents of the invention [0003] The technical problem to be solved by th...
