摘　　要：本文阐述了拔管过程、同管壁厚差、欠酸洗等对拔制力波动性的影响,提出了在自动轧管机上轧头的建议。Influences of tube drawing processes, wall thickness difference in a same tube, insufficient pickiing on the surfaces of a tube on the fluctuation of drawing force are expounded. A proposition to roll pierced shell head on a plug mill is advanced.
