Technical Field

The invention belongs to the technical field of converter metallurgical machinery, and particularly relates to a deslagging device for prolonging the service cycle of a converter oxygen lance and a use method thereof.

Background

In the use process of the original oxygen lance, slag on the surface area of the lance body is removed by a worker through the oxygen lance, in addition, in the cleaning process, the reason that the air flow of the oxygen lance cannot be controlled easily damages the lance body to cause off-line, the field environment is severe, along with the continuous reduction of the workers, the oxygen lance cleaning work cannot be completed, and only other methods are needed to solve the problem.

Disclosure of Invention

The technical problem to be solved is as follows: the application mainly provides a deslagging device for prolonging the service cycle of a converter oxygen lance and a use method thereof, and solves the technical problems that in the prior art, the lance body is easy to damage, the off-line is caused, the oxygen lance cleaning work cannot be completed, and the like.

The technical scheme is as follows:

the utility model provides an increase dross removal mechanism of converter oxygen rifle life cycle, includes two solenoid valves, two cylinders, two push rods, two supporting seats, two scarfing cinder dolly and a set of blade, the solenoid valve links to each other with cylinder one end, and through the switch-on of the interior gas source of solenoid valve control cylinder, the cylinder other end links to each other with the push rod, link to each other through the supporting seat between push rod and the scarfing cinder dolly, a set of blade is established on the semicircle inner wall of scarfing cinder dolly.

As a preferred technical scheme of the invention: one end of the slag remover trolley is connected with the supporting seat, and the other end of the slag remover trolley is inwards sunken to form a semicircle.

As a preferred technical scheme of the invention: the blade is arranged on the semicircular inner wall of the slag remover trolley.

A use method of a deslagging device for increasing the service cycle of a converter oxygen lance specifically comprises the following steps:

the first step is as follows: the deslagging devices which increase the service cycle of the converter oxygen lance are symmetrically arranged and are arranged on two sides of the converter oxygen lance;

the second step is that: after the converter oxygen lance splashes slag or blowing is finished, in the process of lifting the oxygen lance, an operator switches on an air source of an air cylinder by controlling an electromagnetic valve, and the air cylinder pushes a supporting seat on a push rod to close a slag remover trolley;

the third step: the blade extends into the cold steel on the surface of the oxygen lance of the converter and is about 1-3cm away from the surface of the oxygen lance body of the converter, the blade acts on the cold steel on the surface of the oxygen lance of the converter, and the cold steel falls off in the lifting process of the oxygen lance of the converter;

the fourth step: when the converter oxygen lance is lifted up, the blade thoroughly cleans slag and cold steel generated on the surface of the converter oxygen lance body in the blowing process of the converter oxygen lance, and the slag remover trolley is controlled to be separated after slag removal.

Has the advantages that: compared with the prior art, the deslagging device for increasing the service cycle of the converter oxygen lance and the use method thereof adopt the technical scheme, and have the following technical effects:

1. the workload of personnel is reduced, before the design is not available, 6 converter oxygen lances need to be replaced every day for each furnace, and one converter oxygen lance needs to be replaced every three days at present;
