Description

Technical Field

[0001] This utility model belongs to the field of centrifuge technology, and in particular relates to a horizontal casting centrifuge for rolling mills. Background Technology

[0002] The horizontal casting centrifuge is a cutting-edge special casting equipment that utilizes centrifugal force to produce composite rolls (mainly used in the metallurgical steel rolling industry) in a high-speed rotating horizontal state. Centrifugal force tightly binds the denser, higher-melting-point molten metal to the inner wall of the rotating mold, forming a uniform and dense outer layer. Then, a lower-density, more resilient molten metal is poured in, thus casting a bimetallic composite roll in one step—a roll with a hard, wear-resistant outer layer and a strong, impact-resistant core. Existing horizontal casting centrifuges suffer from inconvenient roll removal after casting, cumbersome operation, and reduced production efficiency. Utility Model Content

[0003] In view of the above situation and to overcome the defects of the prior art, the purpose of this utility model is to provide a horizontal casting centrifuge for rolling mills, so as to solve the problem that the rolling mills are inconvenient to remove.

[0004] The technical solution to the technical problem is as follows: It includes a first base and a second base, with multiple sets of springs installed between them. A centrifuge body is rotatably connected to the first base. The centrifuge body has a discharge port on its left side and an end shaft fixed to its right side. A feed pipe connected to the centrifuge body is fixed inside the end shaft. Two support legs and a support base are located below the second base. The two support legs are distributed on the front and rear sides of the second base. A fixed shaft corresponding to the support leg is fixed to the left end of the second base. The fixed shaft is hinged to the support leg. The support base supports the right side of the second base. An inclined hydraulic cylinder is hinged to the support base. A telescopic rod is slidably connected inside the hydraulic cylinder and hinged to the lower end of the second base. The hydraulic cylinder controls the second base to rotate to the left. A bracket is fixed to the right side of the second base. A lifting platform is installed on the bracket. A base plate is fixed to the upper end of the lifting platform. A pouring cup is slidably connected to the base plate, and an interface that mates with the feed pipe is fixed on the pouring cup.

[0005] Preferably, a motor is mounted on the first base, a first pulley is coaxially fixed to the motor, and a second pulley is coaxially fixed to the end shaft. The first pulley is connected to the second pulley via a belt.

[0006] Preferably, the first base is fixed with bearing seats located on the left and right sides of the centrifuge body, and the centrifuge body is installed in the bearing seats via bearings.

[0007] Preferably, the support base is provided with a slot, and the lower end of the second base is fixed with a locking block corresponding to the slot.

[0008] Preferably, an electric push rod is installed on the base plate, and a guide rail corresponding to the pouring cup is fixed on the base plate. The electric push rod controls the pouring cup to slide left and right on the guide rail.

[0009] This utility model has the following advantages over traditional equipment: 1) It has an ingenious structure. Through the hydraulic cylinder structure, it cleverly controls the overall flipping movement of the first base and the second base, so as to realize the free unloading of the rollers in the centrifuge body, which is convenient to take out, simple to operate, and highly stable; 2) It combines the pouring cup, the elevator and the electric push rod structure to facilitate the feeding of the centrifuge body, with a high degree of automation, improved work efficiency, and safety and reliability.
