Embodiment Construction

[0020] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0021] like Figure 1 to Figure 3 As shown, the embodiment of the present invention provides a dummy head for a hollow round billet, including a dummy head body 10 and a connecting piece 20 . The dummy head body 10 is a hollow cylindrical structure with two ends open. One side of the connecting piece 20 is fixedly connected with one end of the dummy head body 10 , and the other side of the connecting piece 20 is provided with an upper rib 21 for connecting with the hollow round billet.

[0022] On the other side of the connecting piece 20, an upper rib plate 21 is arranged. After pouring, the molten steel enters the crystallizer and can be solidified with the upper rib plate 21 to form a bill...

Abstract

The invention provides a dummy bar head for a hollow round billet and a continuous casting machine. The dummy bar head for the hollow round billet comprises a dummy bar head body and a connection piece, wherein the dummy bar head body is of a hollow cylindrical structure with the two ends being open, one side of the connection piece is fixedly connected with one end of the dummy bar head body, andthe other side of the connection piece is provided with upper rib plates used for being connected with the hollow round billet. The dummy bar head for the hollow round billet has the beneficial effects that the upper rib plates are arranged on the other side of the connection piece, after casting starts, molten steel enters a crystallizer and can be solidified with the upper rib plates to form the billet head, by means of the billet head, the billet with the formed billet shell is drawn out from the crystallizer, and therefore the purpose of guiding out the hollow round billet is achieved.

Description

technical field [0001] The invention relates to the technical field of continuous casting in steel production, in particular to a dummy head for a hollow round billet and a continuous casting machine. Background technique [0002] With the development of the iron and steel industry, iron and steel enterprises pay more and more attention to energy saving and consumption reduction. The near-net shape continuous casting technology can save energy, reduce the investment and production cost of subsequent processes, and the hollow round billet continuous casting technology is one of them. At present, seamless steel pipe manufacturers mainly produce seamless steel pipes by the method of solid round billet → perforation → oblique rolling of waste pipe → continuous rolling pipe → reduction and sizing. If the billet is made into a hollow round billet, the perforation can be omitted process, reduce the investment and production cost of pipe-piercing equipment, and have great economic b...
