Effect of Rotational Speed in Vertical Centrifugal Casting on the Wear Properties of Obtained Aluminum Tubes

摘要

The rotational speed of molds plays a predominant role in defining the quality of cast tubes. The melt during the different rotational speeds strongly influences its motion in forming the final cast tube. Here, an Al-2Si alloy was taken for our experiment and cast at various rotational speeds (600-1200rpm) to observe the formation of the tubes. The uniform tube was formed at 1000rpm, the optimum speed, and the non-uniform cast tubes were formed at the other rotational speeds. Small grain sizes and optimum wear characteristics were formed in the cast tube that was rotated at the optimum speed. In other cast tubes formed at the other rotational speeds, coarse grains, pores and poor wear characteristics were formed.
