Description

Technical Field

[0001] The utility model relates to the technical field of steelmaking, in particular to a nozzle structure capable of isolating steel slag. Background Art

[0002] Drainage sand is a special refractory material that ensures that molten steel can flow automatically during ladle casting. It plays a key role in the self-opening rate of the ladle and the quality of the molten steel.

[0003] After the ladle is hot-repaired, the residual steel and slag in the ladle are not emptied in time, resulting in residual steel (liquid) slag flowing into the water inlet when the ladle is erected, and the phenomenon of clogging the water inlet occurs from time to time. Especially after the current ladle covering process is promoted, the reflux residue is more prominent, which seriously affects the self-opening rate.

[0004] Therefore, in view of this, the shortcomings of the existing structure are studied and improved, and a nozzle structure with slag isolation is proposed. Utility Model Content

[0007] Furthermore, a clamp assembly is provided at the junction of the water inlet and the iron shell, and the clamp assembly includes a half clamp, and the half clamp is divided into two left and right parts, and the two half clamp notches are arranged opposite to each other.

[0008] Furthermore, the clamp assembly also includes mounting holes and screws. Four mounting holes are symmetrically provided on the bosses on both sides of the half clamp, and screws are inserted into the mounting holes.

[0009] Furthermore, the clamp assembly also includes a nut and a stop washer. The nut is threadedly fastened to the tail end of the screw, and the stop washer is sleeved between the nut and the screw.

[0010] Furthermore, the clamp assembly also includes foldable ears, and the foldable ears are integrally fixed on both sides of the stop washer, and the junction between the foldable ears and the stop washer can be bent.

[0011] Furthermore, the through holes on both sides of the stop washer are sleeved and matched with the screws in the adjacent mounting holes, and the folded ears on both sides of the stop washer are bent to lock the corresponding nuts.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. When the utility model is in use, the present application can effectively prevent the residual slag ladle from flowing into the water inlet when it is erected and further causing blockage of the water inlet by buckling the iron shell at the top opening of the water inlet and fastening it through the clamp assembly.

[0014] 2. When the utility model is in use, the clamp assembly of the present application is composed of two half hoops on the left and right. When in use, the screw is inserted into the mounting holes at both ends of the half hoop and the locking washers are put on the tails of the two adjacent screws. After tightening the nut, the folding ears on both sides of the locking washer are bent to lock the nut to prevent loosening, which can ensure the long-term fastening of the joint between the water inlet and the iron shell and prevent leakage and falling off caused by loose bolts.
