Description

Technical Field

[0001] The utility model belongs to the technical field of blast furnace smelting, mainly aims at assisting the angle adjustment of a blast furnace opening machine, and more specifically, relates to a device for adjusting the angle of a blast furnace opening machine. Background Art

[0002] During the blast furnace smelting process, molten iron and slag are continuously generated and accumulated in the furnace. The generated slag iron needs to be discharged through the slag hole and iron hole. Timely discharge of the generated slag iron is the main link to ensure the normal production of the blast furnace.

[0003] The significance of fixing the appropriate taphole angle is to keep the dead iron layer at a certain thickness, which is beneficial to protect the furnace bottom and discharge clean slag iron, reduce the erosion rate of the furnace hearth and furnace bottom caused by the molten iron circulation, and ensure sufficient furnace hearth temperature. The taphole machine is designed to have an adjustable angle of 6°-19°. In one generation of furnace campaign, the taphole machine angle needs to be adjusted according to production needs.

[0004] The angle of the opening machine is adjusted by adjusting the different positions of the opening machine fan-shaped plate on the opening machine beam to achieve the purpose of adjusting the angle. However, there are the following difficulties in actual operation:

[0005] (1) Since the beam of the opening machine contains a propulsion mechanism and a drilling mechanism, the total weight of the entire equipment reaches 3 tons, and a crane is required to cooperate with the operation when adjusting the angle;

[0006] (2) When adjusting the angle, the center line of the opening machine is required to remain unchanged, and two front and rear adjustment sections need to be set on the fan-shaped plate of the opening machine. The workload is large and generally takes 2 hours;

[0007] (3) In order to ensure the stability of the opening machine, it is necessary to ensure the strength of the opening machine fan-shaped plate. Therefore, the bolt hole diameter of the opening machine fan-shaped plate is small, and there are 12 corresponding installation holes in the front and back, and the installation accuracy is high. However, the hoisting accuracy of the overhead crane is poor, and it is difficult to ensure the accuracy requirements during the hoisting process. Multiple adjustments are required, which is time-consuming and labor-intensive;

[0008] (4) Due to site limitations, a blast furnace can usually only be equipped with one overhead crane. The overhead crane takes a long time to adjust the angle, affecting other normal operations.

[0009] Therefore, the above-mentioned prior art needs to be improved. Utility Model Content
