Metal bar feeding device for electroslag metallurgy and adding system of metal bar feeding device

Abstract

The invention discloses a metal bar feeding device for electroslag metallurgy and an adding system of the metal bar feeding device, and belongs to the technical field of electroslag metallurgy deoxidation alloying. The metal bar feeding device sequentially comprises a storage area, a material blocking mechanism and a supporting piece from top to bottom, wherein a first discharging opening is formed in the supporting piece; a first opening is formed in the bottom of the storage area, the length direction of the first opening corresponds to the length direction of a metal bar, and the size of the first opening is not smaller than that of the metal bar; the material blocking mechanism is arranged on the supporting piece and comprises a driving part and a material blocking piece, the driving part is connected with the material blocking piece, and the driving part is used for driving the material blocking piece to slide on the supporting piece; and a material passing hole is longitudinally formed in the material blocking piece and corresponds to the first opening, and the size of the material passing hole is not smaller than that of the metal bar. By means of the metal bar feeding device for electroslag metallurgy and the adding system of the metal bar feeding device, precision of metal bar selection can be effectively improved, and the difficulty of manual operation is reduced.

Description

technical field [0001] The invention belongs to the technical field of electroslag metallurgy deoxidation alloying, and more specifically relates to a metal rod feeding device for electroslag metallurgy and an adding system thereof. Background technique [0002] Electroslag metallurgy is both a casting process and a refining and refining process, which can better purify metals and significantly remove non-metallic inclusions. A lot of practice has shown that oxide inclusions in steel are directly related to oxygen content. During remelting, active elements in steel such as Al, Ti, Ce, B, etc. are often lost due to oxidation. How to prevent the oxidation of active elements is one of the important metallurgical problems in electroslag remelting. The electroslag remelting process is generally carried out in the atmosphere. During the remelting process, the slag pool continuously absorbs oxygen from the air and transfers it to the molten pool. This is actually equivalent to an ...
