Both old and new concepts of wear of the grinding rollers
2013-07-10 by seoer3
 Grinding roller is directed to the rolling mill pressure metal processing tools. Grinding roll rolling between the rolling member and the contact between the grinding roller friction, resulting in wear of the grinding roll.
The production of the rolling, grinding roll with a hard oxide withstand cyclic loading  and temperature fluctuations, and in water vapor and air-oxidizing atmosphere, and the interaction of the surrounding liquid and gaseous media, subject to various types of wear mechanism together. In the hot rolling unit is organized according to the production, the amount of each roll a rolling finish replaced after grinding roll. Throughout the rolling units, roll grinding roll undergone great changes, there is a large amount of wear.
As the wear of the grinding roller rolls deformation calculation accuracy, while tensile stress before be rolling pressure and pressure between rolls some impact, it established a grinding wheelroll wear model of the rolling process grinding roll wear prediction.
Maintaining sheet flatness conditions:
Old idea: that the elongation along the width of the same shape for good everywhere.
Disadvantages: does not consider metal lateral flow.
New concept: the plate-shaped transverse thickness difference flatness and influence each other.
Advantages: Consider the lateral flow of metal to ensure flatness flatness and horizontal thickness deviation requirements are met.
