Metal-stream inoculation device for casting

Abstract

The invention discloses a metal-stream inoculation device for casting. The metal-stream inoculation device for casting comprises a nucleating agent bin, wherein the outer side of the nucleating agentbin is symmetrically fixed with two rotary shafts which reversely extend; the nucleating agent bin is rotatably connected onto two detachable brackets through the two rotary shafts; the two detachablebrackets are separately fixed to the two sides of a ladle mouth through support bases; the support bases are fixedly arranged on the ladle mouth, and the nucleating agent bin is positioned above theladle mouth; the bottom of the nucleating agent bin is equipped with a downward opening part which is positioned above the ladle mouth of a casting ladle, and a gate valve is connected on the openingpart; a detachable discharge spout is connected below the gate valve; and the gate valve controls opening and closing of the gate valve through a pushing-pulling rod. The metal-stream inoculation device for casting overcomes the problems in the prior art, has characteristics of being safe and high in practicability, reducing labor intensity, being low in cost and reducing quality risk, can guarantee consistency and stability of a casting material, increases the yield, and is convenient for maintenance.

Description

Technical field [0001] The invention relates to the technical field of casting, in particular to a flow inoculation device for casting. Background technique [0002] In order to obtain high-strength cast iron, it is necessary to carry out multiple inoculation and modification treatments on the molten iron to obtain better quality castings. It is necessary to carry out inoculation during the casting of molten iron to ensure the consistency of casting materials. [0003] In the process of realizing the present invention, the inventor found that the existing inoculation device for casting has at least the following problems: [0004] Most of them use pull-wire switches to control the opening and closing of the drain nozzle, that is, the switch must be held during the entire pouring process, and it will not be released until the pouring is completed, which increases the labor intensity of the pouring workers in the high temperature environment; [0005] The aperture size of the leakage no...

AI Technical Summary

Problems solved by technology

[0008] Most of the inoculant chambers are open, and iron beans may be sprayed into the inoculant chamber during the pouring process, causing the leak nozzle to be blocked and resulting in unqualified castings;

[0009] There is no limit device on the rotation axis of the flow inoculation device. The worker cannot place it accurately in the center of the ladle nozzle when placing it, and there may be lateral displacement during the movement process, resulting in uneven or insufficient inoculation.
