Abstract

The article develops one of the main directions of improving the technology of pipe rolling on a reduction-stretching mill, in order to reduce the end crop. The article describes a speed adjustment technique of the reduction mill, when rolling the front end and back end of pipes, the length of which corresponds to the length of the thickness of ends of the finished pipe. A distinctive feature of the technique is the calculation of volume of the thickness end, which must be reduced by an adjusted value, when rolling the end area in the head stands. The sequence of technological calculations and the results of industrial testing of pipe reduction by standard rolling modes, and modes calculated by the proposed technique, are given. An analysis of the results of industrial testing showed the possibility of reducing the mass of the thickness ends by no less than 7%.
