TMK’s Seversky Pipe Plant in Polevskoy in Russia has successfully commissioned CONDRIVE oscillation systems from SMS Concast, a company of SMS group, on its five-strand bloom casting machine. or more than six months now, the CONDRIVE direct-drive systems have been operating with the expected high precision and reliability and for the first time ever on a resonance oscillation system of a bloom casting machine. The caster is designed for the production of round blooms in diameters from 150 to 400 millimeters. The installed direct oscillation drives from SMS Concast have fully met the customer’s requirements and specifications. The central aims of the installation were to enhance the control of the continuous casting process, improve the product quality and guarantee long-term process reliability along with minimized operating costs. Especially during the casting of small-diameter blooms, which takes place at higher casting speeds, TMK Seversky has been able to reduce the breakout rate to basically zero – thanks to the CONDRIVE oscillation technology.

The CONDRIVE equipment was installed without delaying the production plan. On each strand, the installation took only half a regular maintenance shift. The CONDRIVE systems were immediately ready to start operating, without any additional adjustment.

TMK Seversky is now able to adjust the oscillation curves, frequency and stroke, highly flexibly in an online process, with special consideration of the requirements of the individual steel grades and bloom diameters being cast. Given TMK Seversky’s range of Special Bar Quality tube grades and its various round bloom formats ranging from 150 to 400 millimeters in diameter, the online adjustment of the oscillation curve will contribute significantly to an enhancement of the product quality.

The main component of CONDRIVE is its powerful torque motor with an eccentric shaft connected to the oscillation table by means of a lifting rod. In combination with its highest-precision digital control system, CONDRIVE performs significantly better in terms of acceleration and speed control than other types of systems.
