Abstract In this investigationcauses for casting billet jitter were analyzed and improvement measures were proposed under the consideration of actual situation. Result shows that, in two strand cold chamber the jitter is due to equipment precision and overlarge taper of the crystallizer copper tube. For the production of No.20, 16Mn, 37Mn5 shell which is relatively soft and ductile, jitter does not occur or only slight jitter occurs; but for the production of 40Mn2, 26CrMo, 27CrMo44 which have higher strength and hardness, severe wobble occurs. The using of low viscosity, low melting slag can increase lubrication performance and reduce billet jitter obviously, but fails to eradicate jitter.
