A kind of preparation method of cast steel backup roll

Abstract

The invention discloses a cast steel support roll, which includes a roll body and a roll end shaft. Roll end shafts are respectively provided on the two end side walls of the roll body; the cast steel support roll is produced through the following process: first, the roll is The main body and the roll end shaft are smelted separately, and the horizontal centrifugal casting process is used to fuse the roll main body and the roll end shaft into one body. The lifting plate is controlled to move upward to make the roll leave the ground, and the handrail is pushed to make the fixed plate pass through the two side plates. The support roller moves along the two transverse support rods. The bottoms of the two first slide rails are provided with chute. The tops of the two triangular plates are provided with a number of pulleys. The pulleys are arranged inside the chute to push the two transverse supports. The rod moves along the two first slide rails to realize the longitudinal movement of the grabbing device and move the roller to the next process position, which facilitates the movement of the roller, does not require manual transportation, reduces labor workload, and improves work efficiency.

Description

technical field [0001] The invention relates to the technical field of roll preparation, in particular to a method for preparing a cast steel support roll. Background technique [0002] Cast steel rolls are cheaper to manufacture than forged steel rolls. When the heat treatment system is the same, the wear resistance of cast steel rolls is better than that of forged steel rolls with the same composition, but the toughness is lower. Composite casting can significantly improve the strength and toughness of the cast steel back-up roll core and roll neck. The production of cast steel rolls includes processes such as smelting, casting, heat treatment, machining and testing, but there is a problem of inconvenient movement of the rolls during preparation. [0003] During the preparation process of the existing cast steel backup roll, when the roll is grabbed by the traditional grabbing device, the base of the grabbing device cannot be in a horizontal state, and it is not convenie...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a method for preparing cast steel back-up rolls to solve the problem that the base of the grabbing device cannot be horizontal when the traditional grabbing device is used to grab the roll during the preparation process of the existing cast steel backup rolls. state, it is not convenient for the four suction cups to contact the surface of the main body of the roll, it is not convenient to absorb the main body of the fixed roll, and the purpose of handling cannot be realized; in the preparation process of the existing cast steel support roll, only the grabbing device directly grabs the roll, grabs The force on the device is too large, there is no auxiliary support structure, and the suction force of the suction cup on the main body of the roll cannot be reduced, and the roll is easy to fall off, which is not convenient for the fixing work of the roll; during the preparation process of the existing cast steel support roll, the grabbing device moves Unchanged, or only able to move in one direction, manual handling is required, the labor load is large, and the work efficiency is low
