Movable cleaning device for burr of rectangular continuous casting slab

Abstract

The invention discloses a movable cleaning device for burr of a rectangular continuous casting slab and belongs to the technical field of steel making continuous casting slab production equipment. The movable cleaning device is used for cleaning the burr of the rectangular continuous casting slab. According to the technical scheme of the movable cleaning device, a fixing frame is fixedly connected with a continuous casting slab cutting trolley through a fixing rod, the fixing frame is provided with a sliding rail, a sliding block is arranged on the sliding rail and is in sliding fit with the sliding rail, the sliding block is connected with one end of a connecting rod, the other end of the connecting rod is connected with a fixing arm of a cutting gun, a gas spraying pipe is fixed to the sliding block, one end of the gas spraying pipe is connected with a compressed gas pipeline, the other end of the gas spraying pipe is provided with a gas nozzle, and the gas nozzle is opposite to the rear portion of a flame nozzle of the continuous casting slab cutting gun. The movable cleaning device is reasonable in structure, convenient to use, good in cutting slag blowing effect and capable of effectively blowing continuous casting slab cutting slag away from the surface of the continuous casting slab and meanwhile has the function of synchronously moving with the cutting gun of a continuous casting machine, and the problem that in the cutting process, as the distance between the gas nozzle and the cutting point position is increased, the cutting slag blowing capacity is lowered is solved.

Description

technical field [0001] The invention relates to a movable cleaning device for cleaning burrs of rectangular continuous casting slabs, and belongs to the technical field of steelmaking continuous casting slab production equipment. Background technique [0002] In the continuous casting slab production of the continuous casting machine, in order to facilitate the production and operation of the subsequent rolling process, the continuous casting slab needs to be cut and separated in fixed length and quantity. When the flame cutting machine uses a high-speed flame to cut the billet, the melted molten steel will stick to the slit at the bottom of the billet, thereby forming hard steel burrs containing a large amount of impurities. If the slab burr cannot be removed, the burr will enter the subsequent hot rolling process together with the slab. Due to the high hardness of the burr, when the burr comes into contact with the roll, it will cause damage to the roll, and problems such...

AI Technical Summary

Problems solved by technology

The main disadvantage of these three deburring machines is that after the continuous casting slab is cut, the transportation roller area takes up a large space to install equipment and facilities, so it cannot be installed in the reconstruction of the old continuous casting machine, and it also needs to be equipped with a special drive device and control system , increasing the difficulty of transformation
