Design Principles of Skew Rolling Mill
Skew rolling mill is a rolling technology which is widely used in the metal forming process. It has two basic components – a roller and a die, which are operated at high speed to form a continuous rolling motion. The roller is rotated at an angle to the die, which is produced by the shape of the rollers, the shape of the die, the rollers rotation speed, and the pressure applied to it.
The basic design of a skew rolling mill is simple, with the primary objective of producing round or circular shapes. The main components of the mill are the roller and die, which are positioned in such a way that a rolling action is generated. The roller is rotated at an angle to the die, which is produced by the shape of the rollers, the shape of the die and the speed at which it moves.
Since the specific shape of the rolls and die will heavily influence the quality of the final product, it is important to select the appropriate design for the required application. For instance, for a given application the designer may choose to use a rectangular shape for the rolls and die if a rectangular shaped object is desired.
In terms of material selection, the designer should be aware that the selected materials should be able to withstand high temperatures, stress and wear and tear. Factors to consider when selecting the materials include the speed at which the rollers and die rotate and the thickness and hardness of the material used to produce the desired shape.
Designers should be aware of the fact that the shape of the rolls and die will determine the amount of pressure exerted on the material being rolled. The higher the pressure, the greater the rolling force. This means designers must ensure that the force applied to the material is not too great as this could cause damage to the material.
The rolling speed of the mill is also an important factor to consider when designing a skew rolling mill as it determines the amount of material processed in a given time. Rolling too quickly may cause the material to become overheated, causing it to discolor. Additionally, if the rolling speed is too slow, it may result in an uneven surface finish.
Finally, designers should consider the method of lubrication and cooling of the rolls and die. The lubrication system should be chosen carefully, as it can influence the quality and wear of the die and rolls. The coolants and lubricants should be chosen carefully as well, as they should be able to reduce the temperature of the rolls and die as well as provide adequate lubrication.
To ensure the best rolling performance, designers must be aware of all of these design considerations, as they will help to ensure the highest possible quality product is produced. By taking all of these factors into consideration during the design process, designers can create a mill that produces products of the highest quality and at the most competitive prices.
