Abstract

The invention relates to the technical field of stoppers, in particular to a stopper core rod. The stopper core rod comprises a straight core rod body. A head core rod body is welded to the bottom of the straight core rod body. The bottom of the head core rod body is connected with a filling brick. Air holes communicating with the interior of the straight core rod body are formed in the head core rod body and the filling brick correspondingly. The top of the straight core rod body is connected with a threaded core rod body, and the straight core rod body and the threaded core rod body are connected through a connecting rod. Through holes communicating with the interior of the straight core rod body are formed in the connecting rod and the threaded core rod body correspondingly. The stopper core rod provided by the invention has the advantages of being simple in structure, convenient to use, and capable of saving resources; and after a thread at the threaded end of the threaded core rod body is worn, the threaded core rod body is cut off along an annular cutting groove in the connecting rod, a new threaded core rod body is welded, wasting of the head core rod body and the straight core rod body is avoided, the scrappage of the core rod is decreased, the production cost is lowered, and the gas flow rate in the straight core rod body can be regulated by a user conveniently.

Description

technical field [0001] The invention relates to the technical field of plug rods, in particular to a plug rod mandrel. Background technique [0002] The Tao plug mandrel is generally welded by the head mandrel and the straight mandrel, and the head mandrel and the straight mandrel are both made of bar material. During use, the wire end of the head mandrel fixes the plug head brick, and the straight mandrel covers the sleeve brick to make a Tao plug rod. The Tao plug rod is fixed on the cross arm of the lifting mechanism with a nut by the wire end of the straight mandrel. Because the nut is repeatedly tightened and loosened, the whole mandrel will be scrapped after the wire end of the straight mandrel slips, causing a lot of waste. Increased production costs. [0003] And in the continuous casting process, using the gas injected under the mandrel can obviously benefit the quality of the cast metal. Usually, a chamber is arranged in the mandrel, and one end of the inner cham...
