Description

Technical Field

[0001] The utility model relates to the field of metallurgical equipment, in particular to an oxygen burning and drainage device for continuous casting. Background Art

[0002] In the steelmaking production process, tasks such as drainage and cleaning of cold steel require an oxygen lance. The function of the oxygen lance is to connect the pipeline oxygen to the oxygen lance through a hose, and control the oxygen flow rate through the oxygen lance to complete the work content.

[0003] Before replacing the fixed water nozzle, it is necessary to use an oxygen burning gun to perform oxygen burning operations. When the current small square billet is produced, the continuous casting machine has a high pulling speed. When the pulling speed is greater than 3.5m / min, when replacing the immersed water nozzle, the oxygen burning flow rate is large and the oxygen burning time is greater than 50 seconds, which is easy to cause steel leakage accidents; in addition, after the water nozzle is replaced, it is necessary to deal with the slipped cold steel. Excessive oxygen burning flow rate will cause the slide to burn, and small oxygen burning flow rate will cause low work efficiency. In particular, new employees cannot control the oxygen flow rate by skillfully controlling the oxygen gun valve during the oxygen burning process, which not only causes low work efficiency, but also frequently burns the slide. Summary of the invention

[0004] In view of this, the purpose of the present invention is to provide an oxygen-burning and flow-guiding device for continuous casting to solve the problems raised in the above-mentioned background technology.

[0005] In order to achieve the above purpose, the technical solutions adopted are as follows:

[0006] An oxygen-burning and drainage device for continuous casting comprises a main pipe, one end of which is provided with two air inlets, and the other end of which is connected with an extension pipe 1 and an extension pipe 2;

[0007] A control valve 1 is installed on the main pipe, and a timer and a flow meter are installed on the main pipe;

[0008] The extension tube 1 and the extension tube 2 are connected to the gas nozzle.

[0009] As a further improvement of the utility model, the extension pipe 1 is connected to the control valve 2, and the extension pipe 2 is connected to the control valve 3.

[0010] As a further improvement of the utility model, the diameter of the extension tube 1 is smaller than the diameter of the extension tube 2.

[0011] As a further improvement of the utility model, a hand-held part for preventing slipping is installed on the main pipe.

[0012] The beneficial effects of the utility model are:

[0013] The device provides an oxygen-burning drainage gun with a simple structure, which reduces the difficulty for employees to get started through information such as oxygen burning flow rate and oxygen burning time, and then uses two oxygen pipelines with different diameters to improve employee work efficiency, reduce production accident rate, and prevent oxygen burning and steel leakage accidents.
