TECHNICAL FIELD

[0001] The utility model relates to seamless steel tube production technical field, specifically to a kind of eliminating borax agglomerate's shell car. BACKGROUND

[0002] In the process of producing seamless steel tube, there are two important processes, in order, "piercing" and "rolling". In order to suppress the generation of iron oxide skin under high temperature environment, borax will be sprayed in the shell after "piercing", and then the shell is transported for "rolling". However, in the process of blowing, borax and iron oxide skin melt along the inner wall of the shell, and gather at the bottom of the shell, forming borax agglomerate, which produces internal scarring in the finished seamless steel tube.

[0003] Therefore, in order to correct the above-mentioned defects, we propose a kind of eliminating borax agglomerate's shell car. CONTENT OF THE UTILITY MODEL
