Manufacturing plants for tubes, bars and sections: Driven cold rolling stand improves flexibility and quality.
EJP has received an order from Russian OJSC MMK-METIZ for the supply of two drawing lines to be installed at the Magnitogorsk works. One is a combined drawing line for bright steel with diameters between 8 and 30 mm. It will be the world“s first 30-ton drawing line equipped with a driven cold rolling stand in order to be able to produce square bright steel sections from round input stock. The second line is a chain draw bench line for the production of bars with diameters of up to 68 mm.
With the new lines, which will come with a number of innovative features, MMK-METIZ is going to expand its product range, among others, towards larger diameters. The excellent product quality – e.g. straightness tolerance of 0.1 mm/m and diameter tolerances of h8 and h9 – will provide MMK-Metiz a leading position in the Russian bright steel.
The new lines will boost the works“ output by approx. 15 tons per hour of bright steel products.
Combined drawing line for up to 30 mm diameters
With a drawing force of 30 ton and drawing speeds of up to 80 m/min, the combined drawing line CDS 300 will produce finished bars in diameters from 8 to 30 mm – from coil-to-bar, from coil-to-coil or bar-to-bar, as desired.
As an innovation, EJP is going to install a driven cold rolling stand between the blasting plant and the drawing machine. The function of the rolling stand is to pre-form the material so that it will be possible to directly draw from round to square. The high-precision drive control will make the forming process much more accurately controllable than in the past.
The servo-electric actuation of the drawing jaws achieves more flexibility in bar and tube drawing, cuts the set-up times and reduces the maintenance effort.
Chain draw bench line for up to 68 mm diameters
The DB 800 chain draw bench will be designed for drawing forces of up to 80 t and the production of bars in diameters of up to 68 mm, straight from bar to bar.
Both lines will be equipped with eddy-current testers for inline inspection of the surface quality. In case of small to medium diameters, the machine can process three bars simultaneously.
Denis Kanaev, Director Technology at MMK-Metiz, explains why his company has chosen EJP as supplier: „We conducted a comprehensive market analysis and EJP clearly came out on top when we drew up the technology shortlist. The EJP lines fulfill our requirements one hundred percent. Once our new lines are running, we will be one of the leading producers in Europe in terms of product quality and delivery performance.“
Jacques Paraskevas, Managing Director and Shareholder of EJP, is convinced that having their manufacturing base in Germany has proved to be the right strategy for the company: „The order from MMK-Metiz is the biggest in our company history. However, since then we have already received another order for a combined drawing line CDS 300. One more proof of the continuing good international reputation of technology „Made in Germany“.
EJP will be the general contractor for the supply of the two lines. Installation is scheduled to take place in the fall of 2018, commissioning is slated for spring 2019.
