Abstract
The utility model provides a continuous-casting porous stopper rod, which comprises a stopper rod body and a stopper rod head connected to the bottom of the stopper rod body, wherein an argon gas channel is formed inside the stopper rod body, and extends into the stopper rod head; and a gas guide hole is horizontally formed in the stopper rod head, is vertical to the axis of the argon gas channel, is formed above a contact surface between a water hole and the stopper rod head, and is communicated with the argon gas channel. Compared with the prior art, the continuous-casting porous stopper rod has the advantages that impurity products on a contact part between the water hole and the stopper rod head are well cleaned, the flow speed of molten steel can be controlled more accurately, the bias flow of the molten steel in the water hole is reduced, the unstable state of eddy current is avoided, the integral efficiency of continuous casting is increased, and the quality of the molten steel is improved.
Description
Technical field
The utility model relates to a kind of continuous casting porous stopper.
Background technology
Continuous casting has become the major way of modernized iron and steel enterprise STEELMAKING PRODUCTION.Stopper is that control continuous casting tundish is to the critical elements of molten steel flow and the mold liquid level height of continuous cast mold, by being blown into argon gas the solid impurity product of mouth of a river inwall deposition is washed away, and the solid impurity product in the molten steel in the absorption mouth of a river, the quality of raising molten steel.
As shown in Figure 1, present general stopper comprises a Stopper Body 1 and is arranged on stopper head 2 compositions of Stopper Body 1 bottom, described Stopper Body 1 inside offers ar gas passage 3, offers gas port on the described stopper head 2, and described gas port and ar gas passage 3 are on same axis.During actual the use, the argon gas that is blown in the ar gas passage 3 blows out with the form of the bubble bottom from stopper head 2 by gas port, enters the inner chamber 5 at the mouth of a river 4 through carrying secretly of molten steel, can wash away the solid impurity product of mouth of a river internal chamber wall deposition.But the argon gas bubbles that this stopper blows out can not wash away the solid impurity product of the 4 bowls of section's inwalls in the mouth of a river and stopper head 2 outer walls, namely can not well the mouth of a river 4 and the impurity product of stopper head 2 contact portions be cleaned out.And the accumulation of these impurity products can cause stopper can't accurately control molten steel flow speed, causes molten steel in the mouth of a river 4 bias current to be arranged, and the labile state of eddy current affects the whole efficiency of continuous casting and the quality of molten steel.
The utility model content
The purpose of this utility model is to solve above-mentioned technical problem, and a kind of continuous casting porous stopper is provided.
The purpose of this utility model is achieved through the following technical solutions:
Continuous casting porous stopper, comprise Stopper Body and be connected in the stopper head of Stopper Body bottom, described Stopper Body inside offers ar gas passage, it is inner that described ar gas passage extends to the stopper head, level offers gas port on the described stopper head, described gas port is vertical with the ar gas passage axis, described gas port be arranged on the mouth of a river and stopper head contact-making surface top and with ar gas passage UNICOM.
Preferably, described gas port offers two at least, and described gas port is distributed in the stopper head.
The beneficial effects of the utility model are mainly reflected in: well the impurity product of the mouth of a river and stopper head contact portion is cleaned out, can control more accurately molten steel flow speed, reduce molten steel bias current in the mouth of a river, the labile state of eddy current improves the whole efficiency of continuous casting and the quality of molten steel.
Description of drawings
Below in conjunction with accompanying drawing technical solutions of the utility model are described further:
Fig. 1: existing continuous casting stopper structural representation.
Fig. 2: the utility model continuous casting stopper structural representation.
Fig. 3: the schematic cross-section of the gas port of level among Fig. 2.
Fig. 4: the structural representation of another horizontal gas port in the utility model.
The specific embodiment
The utility model has disclosed a kind of continuous casting porous stopper, such as Fig. 2, shown in Figure 3, comprises Stopper Body 1 and is connected in the stopper head 2 of Stopper Body 1 bottom, and described Stopper Body 1 inside offers ar gas passage 3, and described ar gas passage 3 extends to stopper head 2 inside.Level offers gas port 6 on the described stopper head 2, and described gas port 6 is vertical with ar gas passage 3 axis, described gas port 6 be arranged on the mouth of a river 4 and stopper head 2 contact-making surfaces top and with ar gas passage 3 UNICOMs.In conjunction with Fig. 3, shown in Figure 4, described gas port 6 can arrange as required, offers two or morely, is distributed in the stopper head 2.By interior hole number and big or small quantity and the size of controlling the argon gas bubbles that is blown into the mouth of a river of regulating horizontal gas port 6.The argon gas bubbles of varying number and size enters the solid impurity product that different-grain diameter in the molten steel can be effectively removed at the mouth of a river 4.
The argon gas bubbles that porous stopper of the present utility model blows out can wash away first the solid impurity product of the 4 bowls of section's inwalls in the mouth of a river and the accumulation of stopper head 2 outer walls through the contact area of stopper head 2 and the 4 bowls of sections in the mouth of a river; Then enter mouth of a river inner chamber 5, wash away the accumulated solids impurity product of mouth of a river inner chamber 5 inwalls.This stopper can be controlled molten steel flow speed more accurately, reduces molten steel bias current in the mouth of a river, and the labile state of eddy current improves the whole efficiency of continuous casting and the quality of molten steel.
The utility model still has multiple concrete embodiment, and all employings are equal to replacement or equivalent transformation and all technical schemes of forming, all drop within the claimed scope of the utility model.
