The production of aluminum platinum sleeves with Centrifugal Casting will bring about the surface crack,inner crack and pores,so the measures should be taken such as the reasonable speed and pouring temperature of the mold,the vibration diminution of the work equipment and slow cooling and heat preservation measures so as to eliminate the defects in production to ensure the product quality.

Analyses of Aluminium-inserted Top Roller Manufacturing Technology;

The temperature changes in the outside and inside surface of aluminum cast-rolling roller shell,the formation of thermal stress in shell and the regularity of change were briefly described in the paper.
