Casting roller convexity

Release time:2014-11-06

  Because of the metal deformation is generated when the deformation resistance strong, make the casting roll deflects, therefore changes the shape and size of the roller seam. In order to ensure the flatness, is to consider the appropriate roll has a certain convexity to counteractrolling process by roll bending, flattening, thermal expansion caused by factors such as thedeformation, so the roller sleeve should have a certain degree of convexity.

  In the outer roller sleeve and liquid metal contact, hot and cold alternating action repeatedly,eventually lead to defects such as surface fatigue crack. Therefore, each used for a period of time, the need to re grinding, according to casting roller roller diameter is different, should change the corresponding convex degree.
