Abstract

The most important task of increasing pipe production efficiency is the task of improving the quality of manufactured products. Further development and improvement of pipe manufacturing technology is connected with studying the conditions of contact interaction in the pair “tool – deformed metal”, in particular with creation of separating layer. Application of modern lubricant-deoxidizing materials (hereinafter deoxidant) and modern equipment for their application allows to achieve guaranteed separation of contact surfaces. Also creating of separating layer provides significant advantage in terms of improving the quality of finished tubes, operational reliability of finished products, reducing the cost of production and intensification of deformation processes. However, the uneven distribution of the deoxidant on the inner surface of the sleeve leads to a decrease in the quality of the inner surface of the finished tube, as well as to the uneven wear of the mandrels of continuous mills. One of the reasons for lack of guaranteed separation of contact surfaces is mismatch of blown out portion of deoxidant with the set value. The article describes the principle of operation of standard cyclones and calculates the standard cyclone design. The results of computer simulation of a cyclone of standard design and a modernized cyclone are presented. Also presented the results of physical experiments on particle capture.
