Abstract

The invention discloses a pneumatic lifting system for an oxygen lance. The system comprises a control valve box which is communicated with a gas source, wherein the control valve box is provided with a motor driving end opening; the outer side of the motor driving end opening is connected with a pneumatic motor capable of lifting the oxygen lance; the control valve box is also provided with a cylinder control end opening; the outer side of the cylinder control end opening is connected with a braking cylinder which can be used for braking and locking the pneumatic motor. The pneumatic lifting system for the oxygen lance has the advantages of solving the problems of poor environmental protection and high cost caused by adopting a battery as an emergency power supply in an accident state in the prior art, effectively lowering the cost and improving the environmental protection performance by utilizing compressed air as a power source for the lifting system when an accident happens.

Description

technical field [0001] The invention relates to the technical field of metallurgy, in particular to an oxygen lance pneumatic lifting system used when a circuit accident occurs in a converter steelmaking workshop. Background technique [0002] Top-blown oxygen converter steelmaking is a more popular and common steelmaking process configuration in various steel mills. The main delivery device for oxygen is the oxygen lance, and the oxygen lance is fixed on the lifting and traversing vehicle. A converter is generally equipped with two sets of oxygen lance lifting and traversing vehicles and two oxygen lances, which are used as backup for each other. In the process of blowing (i.e. top-blown oxygen converter steelmaking), the oxygen lance needs to be raised and lowered several times to adjust the position of the lance. It is not only responsible for blowing oxygen to the converter, but also undertakes multiple tasks such as slag splashing and furnace protection. The main hois...
