Description

Technical Field

[0001] The utility model relates to the technical field of converter lining repair, in particular to a converter lining repair device. Background Art

[0002] Furnace repair refers to the repair work of stopping or not stopping the furnace for sudden local damage or vulnerable and eroded parts of the soaking furnace. Generally, amorphous refractory materials are used as furnace repair materials. The converter life is a comprehensive key economic and technical indicator in converter steelmaking. Improving the furnace life can stabilize production and improve converter productivity, reduce refractory consumption, and effectively reduce production costs. The main factor affecting the converter life is the speed at which the converter lining is eroded. In order to ensure the effectiveness of the lining and improve the life of the converter, it is necessary to frequently carry out local repairs on the converter lining.

[0003] The existing Chinese utility model patent with reference announcement number: CN209636268U discloses a converter lining repair device, including a metal nozzle, a base, a car body and a connecting pipe, a first slot plate is vertically fixed on the upper end face of the car body, a first swing slot is provided in the middle of the first slot plate, a second slot plate is vertically fixed on the upper end face of the base, a second swing slot is provided in the middle of the second slot plate, the metal nozzle passes through the first swing slot and the second slot plate, a cylinder is fixed on the upper end face of the car body, an air pump is provided on one side of the cylinder, a cylinder push rod is installed on the cylinder, and the cylinder push rod and the metal nozzle are welded and fixed by a welding sheet. The utility model can assist manual repair of the furnace lining, improve the repair work efficiency and reduce the labor intensity of the repair work.

[0004] When repairing the furnace lining, the repair material is generally sprayed into the inside of the converter through a nozzle. At present, the nozzle angle is generally adjusted manually to swing the nozzle to repair the inside of the furnace lining. Since the inside of the furnace lining is curved, manual adjustment of the nozzle angle for spraying may cause the relative position between the nozzle and the furnace lining to change, resulting in uneven spraying, affecting the spraying effect. At the same time, the nozzle angle of the existing repair equipment cannot be adjusted according to the use requirements during repair, which is very inconvenient. Utility Model Content
