More flexibility for continuous casting machines

Rexroth's high-performance cylinder drive allows users to control all oscillation strengths during the casting process.

High-performance cylinder drive from Bosch Rexroth optimizes mold oscillation

Mold oscillation forms the basis for optimum steel surface quality and the productivity and cost-effectiveness of the entire continuous casting line. Continuous casting lines require not only precise oscillation but also a high level of flexibility in terms of stroke and frequency. Only state-of-the-art electro-hydraulics can provide the required precise movement of heavy masses with respect to all of the oscillation parameters. This is where Bosch Rexroth provides an all-in-one drive and control package made up of well-matched components that can be integrated into any control system: from oscillation cylinders right up to high-performance multi-axis control with software packages.

The electro-hydraulic high-performance linear drive from Bosch Rexroth makes it possible to control all oscillation parameters while casting. Thanks to this flexibility in terms of control, various curve shapes can be implemented in order to optimize the oscillation. Both the stroke amplitude and the oscillation frequency can be varied during the casting process along with the casting speed.

If no radial forces come into play, users can opt for Rexroth's cost-effective high-performance cylinders. The high-performance series of cylinders are of modular design. The modular system comprises of five force levels from 16 to 250 kN with two predefined styles of mounting, those being "trunnion" or "head flange". The equal effective areas of the cylinder ensure good controllability, even with highly dynamic applications up to a maximum frequency of 50 Hz.

The basic version of the high-performance cylinder is fitted with a connection block, associated valves, pressure accumulator, damper accumulator and measuring points. An integrated magnetostrictive position measurement system for position sensing is available as an option.

Intelligent hydraulics for increased availability

Connected hydraulics increase the availability of machinery and plants through condition monitoring and predictive maintenance. For this purpose, Rexroth offers scalable solutions, from individual units with local evaluation to the complete, cloud-based monitoring of large plants. Sensors measure all relevant operating conditions and software detects wear before it leads to failure. Retrofitting kits also economically integrate already installed plants into these concepts.

Linear motion, short time to market

Stand-alone linear axes are the trend. The combination of electrical drive unit and mechanical or hydraulic cylinder reduces installation space and engineering time and combines our specific professional knowledge in one system. With ready-to-mount and i4.0-enabled solution packages, Bosch Rexroth is in line with the current market requirements regarding electrification, digitalization and monitoring as well as condition-based maintenance. The uniform control and drive concept which is used in the different technologies serves as a basis for a short time to market and the economical implementation of hybrid solutions.
