Stopper rod with capability of efficiently blowing argon and function of removing flocculates

Abstract

The invention discloses a stopper rod with the capability of efficiently blowing argon and a function of removing flocculates. The stopper rod comprises wire blocks and a gas permeable material. The wire blocks are mounted on the side walls of an inner cavity, the inner cavity is arranged inside a rod body, a funnel guide pipe is fixed into the inner cavity, the bottom of the funnel guide pipe isconnected with the top of a through hole cone, the through hole cone is mounted in a rod head, the rod head is arranged at the bottom of the rod body, and the gas permeable material is arranged insidethe rod head and is connected with the bottom of the through hole cone. The stopper rod with the capability of efficiently blowing the argon and the function of removing the flocculates has the advantages that the frequent problems of argon blowing type stopper rods and diffusion type stopper rods can be effectively solved by the aid of the stopper rod in a novel structural design, flocculate removal operation can be thoroughly and stably carried out by the stopper rod, and smooth steel casting procedure can be guaranteed; the stopper rod can be prevented from being affected by pressure variation of the argon when the argon is blown by the stopper rod, the uniform and stable argon can be blown out by the stopper rod, and accordingly the liquid level of crystallizers are steady without fluctuation in integral casting procedures.

Description

technical field [0001] The invention relates to the technical field of iron and steel continuous casting equipment, in particular to a stopper rod capable of efficiently blowing argon and having the function of removing flocculation. Background technique [0002] Many equipment and devices are used in the continuous casting process, and the stopper rod is a kind of refractory material rod. It is an essential and important device in the production process of cast steel. [0003] With the continuous development of the steel casting industry, the frequency of use of stoppers has also increased significantly. However, in the process of using traditional stoppers, it was found that when the traditional stoppers were used, once the flocs were in the head of the rod and the nozzle of the middle bag The accumulation in the bowl or the inner cavity of the overall submerged nozzle will seriously affect the normal flow control effect and the amount of molten steel passing through, so ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a stopper that can efficiently blow argon and has the function of removing flocs, so as to solve the problem that the flocs cannot be removed in the above background technology, which may easily cause slag on the liquid surface to affect the quality of the billet, and reduce the single casting Second life increases production cost
