Abstract
The invention provides an adjustable stopper rod for continuous casting. The adjustable stopper rod comprises a stopper rod body, a stopper rod head and an argon gas channel, wherein the stopper rod head is fixed on the front end of the stopper rod body, and the argon gas channel is arranged in the stopper rod body; the stopper rod head is internally provided with an adjustable stopper rod gas-guide tube; the upper end of the gas-guide tube stretches into the argon gas channel, and the lower end of the gas-guide tube is leveled with the bottom of the stopper rod body; and the gas-guide tube and the argon gas channel are on the same axis. The invention has the following main beneficial effects: since the adjustable gas-guide tube is arranged on the stopper rod head, when the adjustable stopper rod is used, the input flow rate of argon gas can be more simply and accurately controlled by setting the inner diameter of the gas-guide tube, thus ensuring the stability of argon gas pressure and being favorable for improving the molten steel quality.
Description
Technical field
The present invention relates to a kind of continuous casting adjustable stopper.
Background technology
Continuous casting has become the main mode of modernized iron and steel enterprise STEELMAKING PRODUCTION.Stopper is continuous casting one of functional refractory, is the critical elements of control continuous casting tundish to the molten steel flow and the mold liquid level height of continuous cast mold.
General stopper as shown in Figure 1, by Stopper Body 2 and the ar gas passage 1 that is arranged on Stopper Body 2 inside, reaches the ar gas passage 1 that designs at 21 places, end of Stopper Body 2 in advance at present, is blown into argon gas in ar gas passage 1, and the tamper of mouth of a river inwall is washed away.The pressure and the flow of the uncontrollable gas of this stopper are blown into argon pressure and flow is suitable, and be too big as flow, and Argon Bubble can make crystallizer molten steel face seethe, and covering slag is rolled in the molten steel and field trash is increased.Can in casting cycle, cause eddy current or molten steel to pour in down a chimney, influence the quality of molten steel.
Summary of the invention
The object of the present invention is to provide a kind of continuous casting adjustable stopper.
Purpose of the present invention is achieved through the following technical solutions: a kind of continuous casting adjustable stopper, comprise Stopper Body, be opened in the ar gas passage in the Stopper Body, be provided with adjustable stopper wireway in the stopper head of wherein said stopper, the upper end of described wireway is stretched into and is arranged in the ar gas passage, the lower end of wireway and the bottom of Stopper Body maintain an equal level, and described wireway and ar gas passage are on same axis.
Beneficial effect of the present invention is mainly reflected in: by setting the internal diameter of wireway, the input flow rate of simpler accurate control argon gas has guaranteed the stable of ar pressure, and the quality that improves molten steel is very helpful.
Description of drawings
Below in conjunction with accompanying drawing technical solution of the present invention is described further:
Fig. 1: common stopper generalized section of the prior art.
Fig. 2: continuous casting of the present invention adjustable stopper generalized section.
Wherein:
1 ar gas passage, 2 Stopper Bodies, 3 stopper heads
21 wireways
The specific embodiment
The present invention has disclosed a kind of continuous casting adjustable stopper, as shown in Figure 2, comprise Stopper Body 2, be opened in the ar gas passage 1 in the Stopper Body 2, be provided with adjustable stopper wireway 21 in the stopper head 3 of described stopper, the upper end of described wireway 21 is stretched into and is arranged in the ar gas passage 1, the bottom of the lower end of wireway 21 and Stopper Body 2 maintains an equal level, and described wireway 21 and ar gas passage 1 are on same axis.The wireway of adjustable stopper of the present invention is a steel, and when isostatic pressing was equipped with, the wireway of steel was put into die head, adds batch mixing again and is pressed into stopper together, can not become flexible after being pressed into, and need not change in the use.Since be small-bore steel tube place with not yielding in the pressing process, ar gas passage can not stop up.And ar gas passage easy deformation or obstruction in pressing process of at present general stopper head.
The flow of argon gas and air pressure are to realize according to the casting condition enactment and by the internal diameter of regulating wireway, the internal diameter of wireway is reserved by experience and calculating when design, in test or when calibration, feed argon gas and measure the gas flow and the air pressure of afterbody at the stopper afterbody for preparing, if do not meet designing requirement then need change the internal diameter of wireway.
The present invention compared with prior art has the following advantages: owing to be provided with adjustable wireway at the head of Stopper Body, in use can be by setting the internal diameter of wireway, the input flow rate of simpler accurate control argon gas, guaranteed the stable of ar pressure, the quality that improves molten steel has been very helpful.
The present invention 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 scope of protection of present invention.
