When the vortex slag suppressor of the continuous casting machine is suspended into the molten steel distributor through the hanging unit, the suppression body is placed in the molten steel of the molten steel distributor. The surface is used to destroy the small vortex formed on the molten steel surface by the vortex phenomenon, so that the scum, heat-retaining agent and slag adsorbent on the molten steel surface will not be distributed with the molten steel along with the small vortex, so as to reduce the steel embryo. The purpose of slagging defects and improving the quality of steel blanks.

Description

Eddy current slag entrapment suppressor for continuous caster

This creation is a continuous caster eddy current slag entrapment suppressor, especially a continuous caster eddy current slag entrapment suppressor that can suppress eddy current to reduce slag inclusion defects in the steel billet.

In the continuous casting process of steelmaking, the ladle transfers the molten steel to the molten steel distributor, and distributes the molten steel to each sprue through the molten steel distributor. The residence time of the molten steel can be prolonged by the molten steel distributor. Promote the floating of the intermediary substances in the molten steel to the molten steel surface. In addition, according to the production requirements, the heat preservation agent and the slag absorbent can be added to the molten steel distributor, thereby improving the heat preservation and gas temperature of the molten steel in the molten steel distributor. Tightness and clarity.

However, when the molten steel in the molten steel distributor is being distributed, eddy currents will occur in the molten steel distributor, causing the scum, heat-retaining agent, and slag absorbent on the molten steel surface to be involved in the molten steel and be distributed accordingly. Involved in the cooling copper mold, resulting in the formation of slag inclusion defects inside the steel billet, which affects the quality of the steel billet.

The main purpose of this creation is to provide a continuous casting machine eddy current slag entrapment suppressor, thereby improving the current eddy current phenomenon in the molten steel distributor, which causes the slag inclusion defect of the steel blank.

In order to achieve the above-mentioned purpose, the eddy current slag entrapment suppressor of the continuous caster of this creation is placed in a molten steel distributor, and the eddy current slag entrapment suppressor of the continuous caster includes: A restraining body made of refractory material; A hanging unit, which is arranged on the top surface of the restraining body; When the eddy current slag entrapment suppressor of the continuous casting machine is suspended into the molten steel distributor through the hanging unit, the suppressing body is placed on the molten steel surface of the molten steel distributor.

In the above, the hanging unit of the eddy current slag entrapment suppressor of the continuous caster can provide a hanging, so that the eddy current slag entrapment suppressor of the continuous caster is hung and sent into the molten steel distributor, so that the suppressor body falls on The molten steel surface of the molten steel distributor, the vortex phenomenon that occurs in the molten steel distributor forms a small vortex on the molten steel surface, and the suppression of the body damages the surface state of the molten steel surface, that is, the damage is sunken in the steel The small vortex of the liquid surface, so the scum, heat-retaining agent and slag absorbing agent on the molten steel surface will not flow down with the small vortex, avoiding the scum, heat-retaining agent and slag absorbing agent on the molten steel surface from passing through the small vortex The molten steel is distributed into the cooling copper mold to effectively improve the slag inclusion defect of the steel billet and improve the quality of the steel billet.

As shown in Figures 1 to 3, the eddy current slag entrapment suppressor of the creative continuous caster is placed in a molten steel distributor 30, and the eddy current slag entrapment suppressor of the continuous caster includes a suppressor body 10 and a hanging list. Element 20, the restraining body 10 is a member made of refractory material, and the restraining body 10 may be a rectangular plate-shaped member, the hanging unit 20 is arranged on the top surface of the restraining body 10, and the hanging unit 20 A lifting ring 21 is included, and the lifting ring 21 is arranged at the center of the top surface of the restraining body 10, wherein the hanging unit 20 can be made of a high-temperature resistant metal material. In addition, the lifting ring 21 can be an iron ring.

When the vortex slag suppressor of the continuous casting machine is suspended into the molten steel distributor 30 through the suspension unit 20, the suppression body 10 is placed in the molten steel 40 contained in the molten steel distributor 30 The molten steel surface. When the molten steel distributor 30 distributes the molten steel 40 for continuous casting, the flow of the molten steel 40 caused by the distribution of the molten steel 40 will generate a vortex phenomenon, and then a small vortex is formed on the molten steel surface, The restraining body 10 that enters the molten steel surface can destroy the state of the molten steel surface, thereby destroying the small vortex formed by the vortex phenomenon on the molten steel surface, so that the scum 50, heat preservation agent and slag absorbent of the molten steel surface will not be prevented. It flows down with the small vortex, and will not be distributed into the cooling copper mold along with the molten steel 40.

To sum up, the eddy current slag entrapment suppressor of the continuous caster can be placed in the molten steel distributor 30 through the hanging unit 20 after starting the casting, and the suppression body 10 can contact the molten steel distributor 30 The molten steel level of the contained molten steel 40 can smoothly destroy the small vortex formed on the molten steel surface due to the vortex phenomenon, and then achieve the goal of keeping the scum 50, heat insulating agent and slag absorbent on the molten steel surface as much as possible. The purpose of distributing the molten steel 40 on the molten steel surface instead of being driven by the small vortex is to effectively reduce the slag inclusion defects of the steel blank, thereby improving the quality of the steel blank.
