Description

Technical Field

[0001] The utility model relates to the technical field of converter slag stopper cones, in particular to an adjustable refractory slag stopper cone. Background Art

[0002] The slag stopper is one of the important equipment in the converter smelting process. It is used to control the separation of molten steel and slag during the steelmaking process, prevent slag from entering the molten steel, and ensure the quality of steelmaking. Slag stopper tapping refers to the operation of releasing molten steel into the steel ladle after the converter blowing is completed and leaving the oxidized slag in the furnace. The slag stopper is a plug made of slag stopper with an inverted cone on the top and a rod on the bottom. Because its shape is close to a funnel shape, it can match the molten steel flow during tapping.

[0003] The existing slag stopper cone cannot adjust the length of the slag stopper rod, which is inconvenient for operators to use. At the same time, the installation process is relatively troublesome and inefficient. Therefore, the utility model proposes an adjustable refractory slag stopper cone to solve the above problems. Utility Model Content

[0006] Preferably, four mounting plates are fixedly connected to the fixing ring, and the mounting plates are provided with limiting holes for the limiting threaded columns to extend into.

[0007] Preferably, a buffer plate is sleeved on the limiting threaded column, and the buffer plate is fixedly connected to the upper end of the slag blocking cone body.

[0008] Preferably, the upper end of the threaded rod passes through the fixed column and the slag blocking cone body in sequence and extends into the interior of the guide rod.

[0009] Preferably, the threaded rod is threadedly connected to the slag stop cone body, and the threaded rod is threadedly connected to the guide rod.

[0010] Preferably, a rotating column is threadedly connected to the limiting threaded column, and the lower end of the guide rod is tightly attached to the upper end of the slag blocking cone body.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] By providing a threaded rod and a high-temperature resistant layer, the threaded rod is threadedly connected to the fixed column, the slag stop cone body and the guide rod. The slag stop cone can be quickly assembled or disassembled by rotating the rotating block, and the convenience is improved. By providing a high-temperature resistant layer, the high-temperature resistance of the guide rod can be improved.
