Embodiment Construction
[0013] The specific implementation manner of the present invention will be described in further detail below by describing the embodiments with reference to the accompanying drawings.
[0014] Such as figure 1 As shown, a slag stopper for steelmaking converter tapping slag stopper includes a slag stopper body 1 , a guide rod 2 and a booster fin block 3 . Preferably, the body 1 of the slag stopper is a half rugby ball structure, one end of the guide rod 2 is connected to the tip of the half rugby ball structure, and the axis of the guide rod 2 is perpendicular to the longitudinal section of the half rugby ball structure.
[0015] The booster fin block 3 is arranged on the other end of the guide rod 2 to provide a boost force for the slag stopper body to enter the taphole of the converter, so that the slag stopper body can quickly and accurately reach the taphole position of the converter.
[0016] The booster fin block 3 is a cone structure, the end face 5 of the cone structur...

The invention discloses a slag baffle piston for baffling slag of steel discharged out of a steel smelting converter. The slag baffle piston comprises a slag baffle piston body and a guide rod, wherein one end of the guide rod is connected with the slag baffle piston body, and a boost wing-flanging block for offering a boost force used for enabling the slag baffle piston body to enter into a steel outlet of the converter to the slag baffle piston body is arranged on the other end of the guide rod. After the slag baffle piston is put into the converter, the boost wing-flanging block is washed by steel flow, a large boost force is generated, the slag baffle piston is quickly pulled to the position of the steel outlet, and the steel flow is quickly reduced; when the steel flow returns to normal, the position of the steel outlet is stably occupied by the slag baffle piston, and the slag baffle piston can not shift; due to a wing-flanging end face of the boost wing-flanging block, the guide rod is effectively controlled to be centered within the steel outlet, and the phenomenon of slag leakage caused by the incorrect piston position can be avoided; and the wing-flanging block is impacted by the steel flow, so that the phenomenon that the slag baffle piston automatically floats can be effectively controlled, and the unavailability of the slag stopping can be avoided.
Description
technical field [0001] The invention relates to the technical field of steelmaking auxiliary equipment, in particular to a slag stopper for steelmaking converter tapping slag stopper. Background technique [0002] In the middle and late stages of converter tapping, start the slag stop trolley and put the slag stopper into the converter. Using the principle that the proportion of molten steel is large, the proportion of converter slag is small, and the proportion of slag stopper is in between, at the end of steel tapping, all molten steel is discharged Go to the ladle under the furnace, and block the converter slag and stay in the converter to prevent the slag from entering the ladle with the molten steel. [0003] The continuous erosion of the high-temperature molten steel on the tapping port of the converter makes the tapping port become larger and larger, the tapping time becomes shorter and shorter, and the molten steel in the converter has a large fluidity. The traditio...
