Automatic regulating lance device for steel making oxygen lance

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...

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 mouth of the converter, and it is necessary to manually adjust the oxygen lance

At present, the diameter of the domestic 300-ton converter oxygen lance is φ402. When the oxygen lance is fed with cooling water, the weight of the oxygen lance is nearly 10 tons. Almost 2 hours of gun time

Manual gun adjustment not only increases the labor intensity of workers, but also reduces labor productivity, which is contrary to modern rapid steelmaking
