Therefore, when the descaling unit works, the descaling box is fixed on the roller bed frame, at the moment, the material pulling rods are all inserted into the gap between the rollers and do not exceed the surface of the roller bed, so that the roller bed can continuously convey steel billets into the descaling box according to the running direction of the steel billets for descaling, and the descaling unit cannot be influenced by the removing unit. When the steel billets need to be removed, the removing unit needs to work, at the moment, the descaling box and the roller bed frame need to be separated firstly, then the descaling box is lifted to remove the descaling box from the roller bed, then the hydraulic cylinder I is used for driving the material pulling rod to rotate upwards, the steel billet frame is separated from the roller bed after the material pulling rod exceeds the roller surface, the steel billets slide down to the steel billet support beside the roller bed along the material pulling rod under the action of gravity after continuing rotating to a certain angle, the blank removing work is finished, then the material pulling rod rotates reversely to return to the roller bed interval again through the reverse action of the hydraulic cylinder I, and the removing work is finished. And then, the descaling box is lowered to the working position, and the descaling box and the roller bed frame are fixed at the same time.
Because the steel billet penetrates through the descaling box and the descaling collecting pipe when the descaling box is ready to be removed, the descaling collecting pipe cannot be made into an annular structure when the descaling box is lifted, and therefore, the upper descaling collecting pipe and the left and right descaling collecting pipes are integrated, namely the upper descaling collecting pipe and the lower descaling collecting pipe can only be manufactured, fed and fixed independently. In the embodiment, the upper descaling header and the descaling box cover plate are welded into a whole and fixedly connected with the descaling box body through bolts, and the high-pressure water inlet pipe enters water from the top and is lifted together with the box body, so that the high-pressure water inlet pipe is connected with a high-pressure water pipe from a descaling pump room through the high-pressure hose 4.

Therefore, the cantilever support is arranged on the other side of the roller way which does not influence the work of the removing unit, and the descaling box is driven by the two hydraulic cylinders II to vertically ascend or vertically descend. When the removing unit is ready to work, the descaling box vertically rises from the working position on the roller way and exceeds the working height of the material stirring rod of the removing unit, after the removing unit finishes working, the descaling box falls back to the initial position and is properly pressurized by the lifting mechanism to enable the descaling box to be tightly attached to the roller way frame, and after the removing unit finishes working, the descaling box restarts descaling.
And when the hydraulic cylinder II is selected, a certain coefficient is properly considered according to the gravity of the descaling box and the upper descaling collecting pipe.

And when the descaling box returns to the working position, all the pins can effectively position the descaling box.
In specific implementation, all the pins positioned on one side of the vertical rod are higher than the maximum rising height of the guide part, so that the pins are still in the corresponding pin holes when the descaling box rises to the highest point; the top ends of all pins on the working side of the removing unit are positioned below the upper surface of the roller way, so that the removing unit is prevented from being influenced.
