Wagu opening and closing device of the charter carrier {Apparatus for opening/closing ladle gate of TLC}

The present invention relates to an opening/closing device for a waggle of a molten iron transport vehicle, and more particularly, by opening and closing the waggu with a cover to prevent contact between the hot water surface of the molten iron and the atmosphere at zero, and to prevent the heat in the molten iron transport container from being released to the atmosphere It relates to a waggu opening/closing device of a molten iron transport vehicle that can minimize the temperature drop of the molten iron during movement.

에 이르는 고온의 용선을 장시간 보관할 수 있다. 여기서 용선은 용선출입구인 와구를 통하여, 용선운반용기의 내외로 출입한다.The Torpedo Ladle Car (TLC) is a facility that transports or stores the molten iron (molten iron) produced in the blast furnace to the post process. This TLC includes a charter vessel whose interior is permanent, semi-permanent, and built-in refractory bricks. This charter vessel is 1500

High-temperature molten iron can be stored for a long time. Here, the chartered ship enters and exits the inside and outside of the chartered ship through the wagu, which is the entrance and exit of the chartered ship.

In general, the TLC is moved or stored and operated with the wagu open to the atmosphere after accommodating the chartered iron. In this case, the temperature of the molten iron may drop due to the inflow of external air during the movement of the TLC, there is a risk of explosion if rainwater flows in through the sump, and the dust generated inside the TLC is released into the atmosphere, causing environmental pollution. can

Patent Document 1 (Registered Patent Publication No. 10-0701394) discloses a molten iron inlet cover as a way to prevent the temperature drop of the molten iron transport container. On the other hand, the disclosed chartered iron inlet cover has the same radius of curvature as the outer circumferential surface of the cylindrical chartered vehicle and opens and closes the chartered charter vehicle by rotating radially along the outer circumferential surface. Here, the molten iron inlet cover is rotatably installed with respect to the outer circumferential surface of the molten iron transport vehicle, and there is a disadvantage in that it operates by a complex driving device including a driving motor, a driving shaft, a coupling, a gear shaft, a guide rail and a guide roller.

In addition, the conventional cover opening and closing device is installed for each TLC, and performs only the operation of opening and closing the molten iron inlet of one TLC.
