Material design and measurement method of rolls in rolling mill(tungsten carbide rollers)

Both the roll and the roll chock are the core parts of the 4 hi wire cold rolling mill, and the roller is the main part of the flat and square wire rolling mill machine that directly rolls the rolling stock. During the rolling process, the rolls are in direct contact with the rolling stock, forcing the rolling stock to undergo plastic changes. At the same time, the rolling rolls are subjected to huge rolling pressure, and the stress of the rolling rolls changes periodically with time due to the rotation of the rolls themselves. .

Under the condition of hot rolling, the profile wire rolling mill machine rolls are severely heated by contacting the high-temperature rolling stock, and at the same time, they are rapidly cooled by water cooling, and the cold and heat are mixed. There are rolling grooves on the roll body, and the pass pattern is arranged according to the requirements of the section steel rolling process. At the same time, wire reducing machine,the hardness of the working surface of the roll is also one of the main quality indicators of the roll.

The requirements for the quality of strip rolling mill rolls are very high, because it determines the quality of rolling mill work, productivity and output quality. At the same time, considering that the working conditions of the rolls are also relatively complex, the strip rolling mill machine rolls adopt high-strength cast steel rolls, forged steel rolls and high-strength cast iron rolls. In this way, the roll can be used for a long time without breaking, and its surface wear is also small.

When using a triangle wire rolling machine to roll different metal materials, the metal will deform under the action of force, and the stand and roll of the square wire rolling mill machine will also be subjected to a certain force, and a certain amount of deformation will also occur under the action of the force. In this way, the gap of the rolls will be changed, and the size of the rolling stock will also be changed.

Therefore, when we design the shaped wire rolling mill machine, we need to consider this problem. In order to ensure its use effect as much as possible, we need to ensure that it has a sufficient rigidity coefficient. This will minimize negative impacts. Usually, the structure and size of the rectangle and wedge wire rolling machine will affect its stiffness coefficient, especially the size of the roll system. We usually set the stiffness coefficient to a common value, and then adjust it according to actual needs.

Of course, wire reduction mill machine,we can obtain the required stiffness coefficient by calculation. However, it is still necessary to obtain the actual required value through measurement. When measuring, we can generally use two different methods to complete, one of which is the rolling method, and the other is the pressing method. Comparatively speaking, the latter is simpler.
