Problems solved by technology

Most of the existing oxygen lance lifting guide rails are frame structures, and the wheels of the lifting trolley rotate in the lifting guide rails of the frame. Due to the machining accuracy and wear, and the weight of the three metal hoses, it is common for the oxygen lance to be fixed on the lifting trolley. There is a certain deviation between the center line of the upper and rear oxygen lance and the center of the furnace mout

Example Embodiment

[0010] The present invention will be further described below in conjunction with the drawings and specific embodiments:

[0011] An automatic gun adjusting device for an oxygen lance for steelmaking, comprising a lifting trolley and a metal hose 2, characterized in that an adjusting plate 1 is provided on the lifting trolley, the metal hose 2 is connected with the adjusting plate 1, and the oxygen lance body 3 It is also fixed on the adjusting plate 1, and the adjusting plate 1, the oxygen lance body 3, and the metal hose 2 are formed as a whole through the fixing device 4. A hemispherical support point 5 is designed on the center of gravity of the whole to act on the trolley body 6 Through this supporting point 5, the whole angle can be adjusted arbitrarily in the horizontal direction. After adjustment, the whole body is fixed to the trolley body 6 through the manual adjustment device 7 and the connecting device 8.

Abstract

The present invention belongs to the field of steelmaking apparatus technology, and is especially an automatic steelmaking oxygen lance regulator. The automatic steelmaking oxygen lance regulator includes an elevating bogie and a metal hose, and features one regulating plate on the elevating bogie connected to the metal hose and for the oxygen lance body to be fixed on; a fixture to fix the regulating plate the oxygen lance body and the metal hose integrally; a hemispherical support for the bogie in the gravitational center of the integral, and a hand regulating unit and a connecting unit to connect the integral and the bogie. The present invention is for regulating the deviation of the oxygen lance center line to the furnace mouth center automatically via rotation, and has the advantages of short regulating time and capacity of raising production efficiency.

Description

technical field [0001] The invention belongs to the technical field of oxygen blowing equipment for steelmaking, in particular to an automatic oxygen gun adjustment device for steelmaking. Background technique [0002] Oxygen lance is an important equipment for oxygen-blowing steelmaking in modern converters. The oxygen lance is fixed on the elevating trolley, connected with two metal water pipes and one metal oxygen pipe fixed on the elevating trolley. Oxygen steelmaking. Most of the existing oxygen lance lifting guide rails are frame structures, and the wheels of the lifting trolley rotate in the lifting guide rails of the frame. Due to the machining accuracy and wear, and the weight of the three metal hoses, it is common for the oxygen lance to be fixed on the lifting trolley. There is a certain deviation between the center line of the oxygen lance and the center of the furnace mouth of the converter, and it is necessary to manually adjust the...
