INVESTIGATION OF PRE-PLUG COMPRESSION RATE IN PIERCING OF HCC BILLET
The effect by pre-plug compression rate on formation of the cavity was investigated in a comparative method with step-down test samples of HCC billet and rolled bloom respectively.The result shows that it is more possible for the HCC billet to form the cavity than the rolled bloom in rotary piercing operation owing to the former's plasticity less than the latter's.
