The stabilizing roll is mainly composed of three parts: the stabilizing roll body, the stabilizing roll neck and the shaft head. The stabilizing roll body is the middle part of the stabilizing roll that actually participates in rolling the metal. It has a smooth cylindrical or grooved surface. The rolling neck is installed in the bearing, and the rolling force is transmitted to the bracket through the bearing seat and the pressing device. The shaft head of the transmission end is connected with the gear seat through the connecting shaft, which transmits the torque of the motor to the stabilizing roller. The stabilizing rolls can be arranged on the frame in the form of two, three, four or more stabilizing rolls. The stabilizer roller produced by Qingdao Hexin Machinery Co., Ltd. has the following advantages:
1. Thermal crack resistance
Coarse stabilizer rolls generally require strength and thermal crack resistance. When selecting the stabilizing roll, the main material of the safety bearing (cast iron, cast steel or forged steel of various grades) should be selected according to the basic strength requirements of the stabilizing roll.
2. Hardness
The speed of the finishing stabilizing roll is high, and the final product must have a certain surface quality. Hardness and wear resistance are the main requirements. Because the wear mechanism of stabilizing rolls is very complex, including mechanical stress, thermal effect, cooling effect, chemical effect of lubricating medium and other functions, there is no unified index to comprehensively evaluate the wear resistance of stabilizing rolls. Since the hardness measurement is simple and can reflect the wear resistance under certain conditions, the radial hardness curve is generally used to approximate the wear resistance index of the stabilizing roll.
3. Impact resistance
In addition, there are some special requirements for the stabilizing roll, such as when the reduction is large, the stabilizing roll has strong bite capacity and impact resistance.
4. Smoothness
When rolling thin-gauge products, the rigidity, structural performance uniformity, machining accuracy and surface finish of the rolling stabilizer are strictly required.
5. Cutting performance
When the stabilizing roll is rolling complex section profiles, the cutting performance of the working layer of the stabilizing roll body should also be considered.
When choosing a stabilizing roll, certain performance requirements of the stabilizing roll are often opposed to each other, and the purchase and maintenance costs of the stabilizing roll are very expensive. Therefore, the advantages and disadvantages of technology and economy should be fully weighed, and casting or forging, alloy or non-alloy, single material or composite material should be decided.
