Steel industryWhen things get heated

Occasionally, higher speeds and shock loads occur in hot strip, cold strip, heavy plate and section mills. For the hot rolling process, the lubrication must have a good resistance to high temperatures and process water. In the cold rolling mill, the product must also be resistant to a chemically active rolling mill emulsion. Thanks to the good wear protection and excellent sealing and corrosion protection, tailor-made BECHEM lubricants optimize the performance and operating time of the system.

BECHEM High-Lub FA 67-400 KS was developed together with the German steel industry, bearing manufacturers and universities for the challenging applications in work roller bearings of rolling mills and is also used in bearings for an operating period of one year without relubrication. For sealed bearings, we have developed our new calcium sulfonate complex grease, BECHEM Complex CM 21. It offers excellent corrosion protection and retains its consistency and lubricating properties even after several years of operation. For roughing stands and slab sizing presses, BECHEM High-Lub FA 50 is successfully in use around the world. The central lubrication of the mill roller tables and peripheral system parts occurs due to the BECHEM High-Lub LT 2 EP or Beruplex CS 2 EP, since these products have a good pumpability and versatile lubrication properties. BECHEM Ceritol PSA 12 H has proven itself for the special requirements of the reeling machine.

In cold rolling mills, the systems are run at significantly higher speeds. The requirements for the lubricant are very demanding in order to ensure that the system runs flaw lessly. Since a chemically active roller emulsion is used in many cases, chemical resistance and high sealing performance are of crucial importance. The immediate risk of overheating exists due to the increased hydrodynamic losses from higher operating speeds. The viscosity and composition of the lubricant must therefore be adapted in terms of the temperature increase and the minimization of the premature lubrication degradation.

The supporting roller bearings are lubricated with BECHEM Ovitol KT 460 VA. Despite the water ingress, the oil provides hydrodynamic lubrication. It quickly separates from the water and the oil film is not affected. To lubricate the oil flow bearing of the supporting roller, BECHEM offers a unique system in which the high performance circulating oil is matched to the process water in each roller mill and is adjusted for each reappointment. This exclusive technology was developed in cooperation with major steel producers and a leading plant engineering company. 

Extensive tests with international partners have shown that BECHEM lubricants make a significant contribution to the economic efficiency of the systems. BECHEM lubricants can also be effectively used for the rollers made for aluminum and copper forming

Many different operations of a metallurgical plant are marked by complex production processes that pose a variety of technical lubrication tasks. BECHEM offers an extensive lubrication range for these conditional. In addition to lubrication greases for general and special applications, it also includes hydraulic fluids, cooling lubricants, corrosion protection media, cable lubricants and chain oils.

Mineral oil basic and synthetic lubricating oils are avail able for gears and oil circulation. The mineral-based oils of the BECHEM Staroil G series cover many applications reliably. Synthetic oils are recommended in the case of special conditions, such as elevated temperatures, larger loads, previously damaged drives or longer oil change intervals. Here the poly-alpha-olefins of the Berusynth GPX series or the polyglycols of the Berusynth EPX series have stood the test worldwide.
