Russian world market leader benefits from new Reika Technology

Reika Straightener setting new quality standards

It is almost half a year since Reika delivered another 10-Roll-Straightening machine to a leading tube producer in the Ural region in Russia. Today, Reika’s model RRM103 is setting new standards in precision right from the production debut in the Russian global players’ workshop.
Since the on-schedule start of production at the beginning of this year, the high-performance system ensures a tube straightness of less than 0.2 mm / m over the entire tube length. Even the ends of up to 12-meter-long tubes are almost completely straightened due to the optimized roller arrangement and geometry. "Exactly for this reason it was an easy decision for the customer to choose once more our straightening technology. Above all, quality is the key to advantage in competition with other tube manufacturers. Today, a serious company can hardly afford to produce scrap.", Hans-Jörg Braun, Reika’s Managing Director, says.

The new generation of 10-Roll-Straightening machines provides many advantages to tube manufacturers. In addition to the straightened tube ends, the machines offer a self-learning multi-axis control and intelligent database analysis as quality standards. For example, process settings of precisely straightened tubes are stored in a database to reproduce the high quality in a reliable way. "We claim to provide our customers with optimum quality of all tubes, not only for some very good ones and this for as many years as possible” explains Braun.

Reika Straighteners ensure long life cycle time

Hence, the Reika engineers carefully sought to ensure the durability of the straighteners. Model RRM103 features a robust, rigid and long-life closed steel frame structure without columns to fight effects like vibrations during the straightening process to the minimum. The enormous mechanic rigidity of the steel frame and the roller carriers ensure a long lifetime and low maintenance costs of the straightening machines, "For the Russian market this is a significant issue," Braun says. He knows the requirements and rough operating conditions in the Russian mills from own experience. The Russians quickly realized the robustness of the equipment and precision of the tubes straightened over the entire length.

Additional benefits include individual drives to ensure wear compensation by simple calibrating. Furthermore, a dynamic process monitoring is integrated to run each roller at optimum capacity. The roller wear is minimized by using individual drives and avoiding   friction between the tubes and the straightening rollers. The prototype of this new generation of straightening machines was delivered 12 years ago to the largest German precision tube manufacturer and the first rollers of this straightener are still in use. There is less strain on the roller material and the tube surface. Even prior to straightening, the ingoing tube is set to optimum rotation and speed by special tube drivers. Material protecting inlet and outlet troughs are also part of Reika’s production program. Scale layers of hot-rolled tubes will be discharged during the straightening process via the inclined machine bed and a vibrating chute.

All those benefits ensure not only efficiency and profitability but also the customers confidence in Reika’s products. The Russian precision tube manufacturer is working with a Reika 10-Roller-Straightening machine since 2012 and knows the benefits. Today the Russian corporation is producing tube diameters in a wide range with the latest Reika technology – with top precision in the most economical way
