A floating non-ferrous metal hot roll and processing method

Abstract

The invention discloses a floating non-ferrous metal hot rolling roll and a processing method. The invention adds a floating interlayer in the floating gap between the outer shell and the inner core, and in order to increase the connection between the floating interlayer and the outer shell and the inner core stability, and slightly improve the strength and wear resistance of the floating interlayer. The floating interlayer of the present invention is composed of polypropylene, hexagonal boron nitride, ceramic powder, glass fiber powder and silica gel. The present invention adds polypropylene to the silica gel , increasing the wear resistance of the floating interlayer, adding a small amount of ceramic powder and glass fiber powder is to improve the strength of the floating interlayer, slightly reduce the floatability of the floating interlayer, and facilitate the hot pressing of the outer shell, and adding hexagonal boron nitride, due to Hexagonal boron nitride has a six-sided crystal structure, which greatly increases the adsorption surface area of ​​the floating interlayer, the outer shell and the inner core, and greatly enhances the connection stability between the floating interlayer and the outer shell and the inner core.

Description

technical field [0001] The invention relates to a floating nonferrous metal hot rolling roll and a processing method. Background technique [0002] The roll is an important part of the rolling mill in the rolling mill and an important consumable part that determines the efficiency of the rolling mill and the quality of the rolled product. The rolls use the pressure generated by a pair or a group of rolls to roll the rolled piece, so that the rolled piece produces plastic deformation and obtains an ideal design shape. Therefore, the quality of the roll is directly related to the surface quality of the rolled product and the rolled steel. machine productivity. It mainly bears the dynamic and static loads during rolling, the influence of wear and temperature changes. The existing rolls and rolling parts have no cushioning toughness when they contact each other, which makes the breakage rate of the rolls very high. Generally, the rolls are integrated. The structure must be rep...

AI Technical Summary

Problems solved by technology

It mainly bears the dynamic and static loads during rolling, the influence of wear and temperature changes. The existing rolls and rolling parts have no cushioning toughness when they contact each other, which makes the breakage rate of the rolls very high. Generally, the rolls are integrated. The structure must be replaced as a whole after a period of use, causing a cost burden on the enterprise, and the operation cycle is not high, which affects efficiency
