[0004] In the above scheme, the method of rapid cooling the surface of roll is used to delay wear, which still has the following disadvantages: when the roll is working, the shoulder of the roll will be in sliding contact friction state for a long time during rotation, which may cause roll wear for a long time, affecting the accuracy of roll grinding. UTILITY MODEL CONTENTS

[0005] The utility model aims at providing a kind of shoulder sleeve working roll to solve the problem that the shoulder of the roll will be in sliding contact friction state for a long time during rotation when the roll is working, which may cause roll wear for a long time, affecting the accuracy of roll grinding.

[0006] To achieve the above-mentioned utility model purposes, the utility model adopts the following technical solutions: a kind of shoulder sleeve working roll, including mounting plate, the top surface of the mounting plate is fixed with two fixed plates, the top surface of the fixed plate is fixed with bracket, the upper of the mounting plate is rotatably provided with working roll inner layer, the both ends of the working roll inner layer are respectively fixed with shoulder column, the shoulder column is fixed with shoulder sleeve on, the top surface of the bracket is fixed with two towa, the towa supports shoulder column upward.

[0007] Preferably, one end of the shoulder column is fixed with roll neck, the both ends of the two roll necks away from each other are respectively fixed with flat head, the top surface of the mounting plate is fixed with grinding machine, the top surface of the mounting plate is fixed with support plate, the grinding machine is rotatably arranged with flat head, and the support plate is rotatably arranged with another flat head.

[0008] Preferably, the surface of the roll neck is provided with a locking groove, and the inner side of the locking groove is provided with a limiting groove.

[0009] Preferably, the bottom surface of the mounting plate is fixed with a supporting column, and the bottom end of the supporting column is fixed with a stabilizing plate.

[0010] Preferably, the bottom surface of the stabilizing plate is detachably provided with a non-slip pad, the top surface of the stabilizing plate is provided with two loading and unloading openings, the top surface of the non-slip pad is fixed with two connecting plates, the connecting plates are slidably arranged with the loading and unloading openings, and the top surface of the connecting plates is fixed with a flexible plate.

[0011] Preferably, the working roll inner layer is fixed with a working roll outer layer, and the working roll outer layer is made of high-chromium white cast iron.

[0012] Compared with the prior art, the shoulder sleeve working roll has the following beneficial effects:

[0013] I. When the working roll inner layer is ground on the grinding machine, the working roll inner layer and the shoulder column both have the characteristics of being resistant to fracture but not resistant to wear. Then the staff installs the shoulder sleeve made of high-carbon chromium steel-based wear-resistant material on the shoulder column, so that the surface of the shoulder sleeve contacts the bearing, thereby increasing the wear resistance of the shoulder column. The wear of the shoulder sleeve is small when the working roll inner layer rotates, which can improve the grinding precision of the roll and provide high-precision rolls for the rolling line, ensuring the control of the hot rolled strip.

[0014] II. The working roll outer layer is made of high-chromium white cast iron containing carbide, which is a high-wear-resistant material. When the bearing is installed on the roll neck, it is installed in the locking groove by using a snap ring, and the two bearing boxes are fixed on the roll neck. When the stabilizing plate supports the supporting column upward, the supporting column exerts a downward force on the non-slip pad, increasing the pressure of the non-slip pad on the ground, thereby increasing the friction of the stabilizing plate on the ground. When the non-slip pad is damaged, the staff bends the flexible plate and removes the connecting plate from the loading and unloading opening, increasing the convenience of the staff when replacing the non-slip pad.
