Description

Technical Field

[0001] The utility model belongs to the technical field of converter steelmaking nozzles, and more specifically relates to a converter steelmaking nozzle connection mechanism. Background Art

[0002] The steelmaking converter is an important production tool in the field of ironmaking and steelmaking. The converter is equipped with a nozzle structure for the inflow and outflow of molten iron or molten steel. The molten iron or molten steel in processing has a relatively high heat. Excessive temperature will affect the material of the nozzle. Therefore, the steelmaking nozzle needs to be replaced frequently to ensure production needs.

[0003] The common nozzle structure is simple. The nozzle structure is inserted into the corresponding position of the converter, and then tightened and fixed by bolts. During installation, it is necessary to ensure that the installation position of the nozzle is accurate. The deviation during installation will affect the coordination between the nozzle and the converter, and will affect the operation of the nozzle after installation. The common positioning structure is relatively simple, and it is necessary to align with each point during positioning, which is troublesome to operate. Moreover, it is also necessary to fix it in the positioned state, and install each screw on the equipment while ensuring the stability of the nozzle equipment. Moreover, there are many screws that need to be fixed, and it is necessary to use tightening tools to fix the screws one by one, which is troublesome to operate. Moreover, most common tightening tools are wrenches. In order to ensure stable force and tighten the fixed screws, a long force arm is required to ensure the construction effect. The larger wrench will be limited by the protruding part of the nozzle when used, and the one-time rotation range cannot be too large, which affects the installation operation of the workers.

[0050] Furthermore, the matching accuracy between the second positioning column 6 and the second positioning hole 7 is greater than the matching accuracy between the first positioning column 5 and the first positioning hole 4. When the end of the first positioning column 5 away from the mounting frame 2 passes through the first positioning hole 4, the second positioning column 6 contacts the second positioning hole 7.

[0051] In this embodiment, a plurality of second positioning posts 6 are distributed around the circumference of the nozzle body 1 .
