Abstract

본 발명은 턴디쉬내에서의 충분한 용강의 버블링을 발생시켜 고품질의 청정강을 제조할 수 있게 하는 제강용 턴디쉬의 스토퍼를 제공하기 위하여 레이들에 의해 턴디쉬로 이송된 용강이 용강유출구를 통해 적절한 주입류의 제어상태로 몰드에 주입될 수 있도록 컨트롤러에 의해 용강유출구를 개폐하며, 외부튜브로부터 공급되는 알곤가스가 유입될 수 있는 중공을 형성한 제강용 턴디쉬의 스토퍼에 있어서, 상기 외부튜브를 통한 알곤가스의 유통량을 증대시키기 위해 그 하부에 다공성 내화물을 장착한 스토퍼의 중공에 직교 상태로 연통되는 다수의 버블링홀을 형성하여 됨을 특징으로 한다.The present invention provides a molten steel outlet which is transferred to a tundish by a ladle in order to provide a stopper of a steelmaking tundish that generates bubbling of sufficient molten steel in the tundish to produce high quality clean steel. In the stopper of the steelmaking tundish formed by the opening and closing of the molten steel outlet by the controller to be injected into the mold in a controlled state of the appropriate injection flow, the hollow argon gas supplied from the outer tube can be introduced, In order to increase the flow rate of argon gas through the tube it is characterized in that it forms a plurality of bubbling holes communicating in a perpendicular state to the hollow of the stopper equipped with a porous refractory in the lower portion.

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음As this is a public information case, the full text was not included.

제2도는 본 발명의 적용 상태를 나타내는 도면, 제3도는 본 발명에 의한 제강용 턴디쉬의 스토퍼를 나타내는 도면이다.FIG. 2 is a view showing an application state of the present invention, and FIG. 3 is a view showing a stopper of a steelmaking tundish according to the present invention.

Claims (1)

레이들(22)에 의해 턴디쉬(18)로 이송된 용강이 용강유출구(24)를 통해 적절한 주입류의 제어 상태로 몰드에 주입될 수 있도록 컨트롤러(10)에 의해 용강유출구(24)를 개폐하며, 외부튜브(2)로부터 공급되는 알곤가스가 유입될 수 있는 중공(4)을 형성한 제강용 턴디쉬(18)의 스토퍼에 있어서, 상기 외부튜브(2)를 통한 알곤가스의 유통량을 증대시키기 위해 그 하부에 다공성 내화물(16)을 장착한 스토퍼(14)의 중공(4)에 직교 상태로 연통되는 다수의 버블링홀(28)을 형성하여 구성됨을 특징으로 하는 제강용 턴디쉬의 스토퍼.The molten steel outlet 24 is opened and closed by the controller 10 so that the molten steel conveyed to the tundish 18 by the ladle 22 can be injected into the mold through the molten steel outlet 24 in a controlled state of proper injection flow. And a stopper of the steelmaking tundish 18 having the hollow 4 through which the argon gas supplied from the outer tube 2 can be introduced, thereby increasing the flow rate of argon gas through the outer tube 2. To the stopper of the steelmaking tundish characterized in that it is formed by forming a plurality of bubbling holes (28) in communication with the orthogonal state to the hollow (4) of the stopper (14) equipped with a porous refractory (16) in the lower portion. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
