Detailed Description

In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention is further described below with reference to the following embodiments.

As shown in fig. 1 and 3, a pearlite nodular cast iron roll for rolling mill, including shaft 3, roll neck 1 and spindle nose 9, 3 one sides of shaft are provided with spindle nose 9, and 3 opposite sides of shaft are provided with

roll neck

1, 3 peripheral one end welding that is close to roll neck 1 of roll body has holding

ring

2, and 1 peripheral one end that is close to spindle nose 9 of roll neck is provided with shift ring 4, bearing 11 is installed through the preformed groove in 4 one side tops of shift ring and the bottom surface, 3 tops of shaft and top one side all through screw installation location section of

thick bamboo

6, and 6 one side surfaces of a location section of thick bamboo install screw rod 5 through the preformed groove, 5 one end of screw rod is located bearing 11's rolling circle.

In this embodiment, as shown in fig. 1 and 3, the two screws 5 are matched with each other, and can limit the moving ring 4, so as to prevent the moving ring 4 from rotating, and the screws 5 are connected with the moving ring 4 through the bearing 11, so when the two screws 5 rotate simultaneously, the position of the moving ring 4 can be changed, and further, the distance between the moving ring 4 and the positioning ring 2 meets the requirement, and it is necessary to ensure that the thickness of the steel strip is greater than the wall thickness of the moving ring 4 and the positioning ring 2, so that the rolling operation can be performed on the steel strip after the roller is matched with other rollers.
