Slag-blocking structure for automatic argon-blowing joint device

Abstract

The invention provides a slag-blocking structure for an automatic argon-blowing joint device. The structure can overcome the problem of proneness to accumulation of slag and ash of a male joint terminal in conventional automatic argon-blowing joint devices, can effectively block high-temperature steel slag from splashing onto a spring of the male joint terminal and ensures service life of the spring. According to the invention, the slag-blocking structure comprises a female joint terminal and the male joint terminal of the automatic argon-blowing joint device, wherein the female joint terminal is arranged on the tank wall of a liquid steel tank, and the male joint terminal is arranged on a support of transloading equipment. The slag-blocking structure is characterized in that the slag-blocking structure further comprises a slag-blocking device installed on the support of the transloading equipment, and the slag-blocking device comprises a rotatable slag-blocking plate; when the female joint terminal and the male joint terminal of the automatic argon-blowing joint device are disconnected, the slag-blocking plate located right above the male joint terminal blocks high-temperature steel slag; and when the female joint terminal and the male joint terminal of the automatic argon-blowing joint device need to be connected, the slag-blocking plate can downward rotate so as to allow the joint body of the male joint terminal to be exposed and engaged with the joint body of the female joint terminal.

Description

technical field [0001] The invention relates to the field of auxiliary equipment in the steelmaking production process, in particular to a slag retaining structure of an automatic argon blowing joint device. Background technique [0002] During the molten steel transfer process under the furnace, the molten steel tank needs to blow argon to the molten steel to achieve the effect of stirring the molten steel. Generally, argon blowing devices are usually installed on the transfer equipment under the furnace, such as molten steel tank cars and ladle turrets. When the molten steel When the tank is dropped, it is necessary to connect the argon pipeline of the molten steel tank with the argon blowing device on the transfer equipment. At present, most of the docking operations are performed manually through quick-change joints. Due to the heat dissipation of the molten steel during transfer It will cause the precipitation of sulfur and phosphorus in the molten steel, resulting in t...
