Embodiment Construction
[0011] In the figure, the gun adjustment device 1 is in the standby position when not in use. When in use, the entire device 1 is rotated to the working position, and the position is fixed with the limit position 3 in the figure, and the limit bolt is screwed into the nut to ensure its accuracy. Then turn on the light 6, and the operator watches the light on the calibration head on the oxygen lance lifting trolley to adjust the oxygen lance. After the adjustment, turn off the light 6, rotate the gun adjustment device to the standby position, and fix it with the limit position 4 It is enough to meet the normal production needs.

The invention relates to an overhauling position lance adjusting device for a converter oxygen lance. According to the technical scheme adopted by the invention, an oxygen lance adjusting device (comprising several parts such as a correction head, a bracket and a limiting part) is arranged at an oxygen lance overhauling position; the correction head is a cylinder of which the upper section is uniformly provided with punched holes and below which a bulb is arranged; and both the position and the central position of the correction head can be determined. During lance adjustment, an electric lamp is turned on; and the lance adjusting device is turned to a lance adjusting position, and a limiting bolt is screwed into a nut, so that the accuracy of the device can be guaranteed. The device has the beneficial effects of convenience, fastness, long service period and low cost. Error between a central line of the oxygen lance and a central line of a converter body can be reduced; the lance adjusting time can be shortened; conflict with production can be prevented; meanwhile, the labor intensity of workers is reduced.
Description
Technical field [0001] The invention is suitable for adjusting the oxygen lance at the maintenance position of a steelmaking plant with a tense production rhythm, which can reduce the error between the center line of the oxygen lance and the center line of the furnace body, shorten the time for adjusting the lance, avoid conflicts with production, and reduce the labor intensity of workers. Background technique [0002] During the production process of the steel plant, if the oxygen lance has a problem, it must be replaced online, which will affect the normal production. The replacement of the oxygen lance can be carried out in the spare position, but the oxygen lance needs to be lowered to the lower lance hole of the moving section of the flue for operation. , and the working position of the oxygen lance and the oxygen lance lifting trolley must be adjusted by a special person, and the operator must follow the lifting trolley to move up and down, until the oxygen lance tip en...
