Abstract

The invention discloses a slag removal device capable of increasing a service cycle of a converter oxygen lance and a using method of the slag removal device. The slag removal device comprises two solenoid valves, two gas cylinders, two pushing rods, two supporting bases, two slag clearer trolleys and a group of blades, wherein the solenoid valves are connected to ends of the gas cylinders; gas sources in the gas cylinders are controlled to connect through the solenoid valves; the other ends of the gas cylinders are connected to the pushing rods; the pushing rods are connected to the slag clearer trolleys through the supporting bases; and one group of blades is arranged on the semicircular inner walls of the slag clearer trolleys. The slag removal device reduces workload of staff, needs tochange 6 converter oxygen lances one day for each stove while the design is absent, and now only needs to change on converter oxygen lance averagely every three days for each stove.

Description

technical field [0001] The invention belongs to the technical field of converter metallurgical machinery, and in particular relates to a slag removal device for increasing the service life of a converter oxygen lance and a use method thereof. Background technique [0002] During the use of the original oxygen gun, the slag on the surface of the gun body is removed by the staff with the oxygen blowing tube to remove the cold steel on the surface of the oxygen gun, and during the cleaning process, the air flow of the oxygen blowing tube cannot be controlled, which is easy to damage the gun body It led to the offline, and the site environment was harsh. With the continuous reduction of personnel, the cleaning of the oxygen lance could not be completed, so we had to think of other ways to solve it. Contents of the invention [0003] Technical problem to be solved: This application mainly proposes a slag removal device and its use method that increase the service life of th...
