Description

Technical Field

[0001] The utility model relates to the technical field of refractory injection equipment, in particular to a refractory injection device for a ladle lining. Background Art

[0002] The steel ladle is used in steel mills and foundries to receive molten steel and perform pouring operations in front of open hearth furnaces, electric furnaces or converters. The structural types include plugger type and sliding nozzle type. The gantry is equipped with two types: hook-off type and bearing type. The lifting mechanism of the plugger type ladle is equipped with a sliding rod gap elimination mechanism to ensure the consistency of the plugger center and the nozzle center after repeated use.

[0003] Most of the existing ladle lining refractory material injection devices adopt a lifting structure, but the lifting process takes a lot of time, which seriously affects the work efficiency. At the same time, the existing ladle lining refractory material injection device needs to be paired with a ladle of corresponding caliber for use, and its applicability is poor.

[0004] For example, a transfer ladle lining refractory material injection device disclosed in Chinese patent publication number CN214160191U, the injection device is connected by a fixed seat and a movable seat, and the movable seat is rotatably connected to the fixed seat. At the same time, the gas rod is connected to the movable seat by a connecting rod. When the device is injecting, the extension and retraction of the gas rod can drive the movable seat to rise and fall, and the "V"-shaped structure of the movable seat and the fixed seat enables the discharge seat to inject the ladle lining at a vertical angle while the position of the device body remains unchanged. Compared with the existing lifting injection type, the injection process and the required time are greatly reduced, thereby improving work efficiency. In conjunction with the rotational connection between the main body and the fixed disk, the main body is driven to rotate by an external device, thereby quickly completing the entire injection of the ladle lining.

[0005] The existing technology has the following problems:

[0006] The above-mentioned device changes the lifting type injection operation of the prior art by forming a V-shaped structure with a movable seat and a fixed seat. Both the lifting type injection of the prior art and the telescopic type injection of the present device are injected through a single nozzle type, thereby reducing the injection efficiency of the refractory material in the ladle lining.
