Simulating Calculation of Frictional Force between Mold and Billet

摘要

Assumption about the inner surface of mold is made according to the forming mechani- sms of frictional force. The frictional force between billet and mold can be analysed by calculating the thermal shrinkage and the shearing strength of the meniscus. The model is used to calculate the maximum drawing speed at different conditions. The results are very satisfactory.
