Timken: Bearing specialist for rolling mill equipment
The World Steel Association recently stated that global steel demand has begun to gradually bottom out and will rebound in the US, Europe and Japan in 2010. As demand is stronger and customers no longer reduce inventory, global steel demand is expected to grow by 9.2% next year, returning to 2008 levels. Rolling mill equipment is one of the important equipments in steel smelting. In the future, steel demand will increase, and the demand for rolling mill equipment will also increase simultaneously. At the same time, higher requirements are placed on the quality of rolling mill equipment. In the metallurgical industry, rolling mills are in a very demanding working environment. The rolling mill is required to withstand the adverse effects of high temperature, heavy load, water and dust on the bearing conditions. As the inventor of tapered roller bearings and the largest manufacturer of tapered roller bearings, Timken began to produce pure steel in the 1920s. Through the manual operation of the rolling mill, Timken has a deep understanding of the metallurgical industry. We also know the needs of steel mill customers for bearing products and services. Since entering the Chinese market in 1992, Timken has been used in rolling mill applications such as wide plate, hot rolling, cold rolling, pickling, galvanizing, and leveling, or in continuous casting machines, converter trunnions, uncoilers, and coiling. Machines, disc shears, and conveyors and other auxiliary equipment applications provide customers with cost-effective bearing products and services. At the same time, they also provide the best rolling mill equipment solutions for domestic well-known metallurgical equipment manufacturers and steel companies. Program. Work rolls are subject to very high radial loads and varying degrees of axial loading. To withstand these loads, double-row, four-row cones, or four-row cones with axial thrust bearings are the most cost-effective solution. B. Support roller When the work roll is subjected to heavier loads due to bending force or roll force, the support roll mainly receives the actual product rolling force. Regardless of whether the bearings are used to reduce the rollbeat of the old mill or the performance of the automatic clearance control (AGC) system, it is critical to select the proper bearing. According to the working conditions, the support roller generally uses four rows of tapered roller bearings or four rows of cylindrical roller bearings. C. Pressing mechanism The pressing mechanism is used to adjust the thickness of the rolled product. In this type of mechanism, the bearing is essentially stationary and must withstand high rolling forces. Timken has developed a variety of heavy-duty thrust-down bearings for this application. D. Rolling mill drive / pinion frame For applications where most loads are radial and axial, Timken offers a combination of conical, cylindrical and self-aligning (single and double row) bearing combinations. E. Auxiliary equipment For the complete rolling mill solution, Timken offers the bearings needed for rolling mill auxiliary equipment. Including conveyor raceways, AP bearings, spherical roller bearings and spherical roller bearings with bearings; coilers, uncoilers, rolling mill gearboxes and flying shears. Timken not only provides customers with quality bearing products, but also offers a wide range of services including bearing repair, professional training and solutions.

Rolling mill bearing applications
With professional materials science and precision manufacturing technology, Timken has developed a variety of high-quality bearings including four-row tapered roller bearings, four-row cylindrical roller bearings, sealed roller neck bearings, spherical roller bearings and so on. It is widely used in key parts such as rolling mill work rolls, intermediate rolls and support rolls, as well as rolling mill auxiliary equipment. Timken offers a full range of innovative solutions for the following products.
A. Work roll
Depending on the type of mill application, Timken has developed bearings for a variety of applications. According to the different application needs of customers, comprehensive consideration of load, speed, lubrication, eccentricity, pollution and other factors, to design the most suitable bearings for customers. For example, the development of Timken's DuraSpexx® bearings benefits from advanced design, efficient production, and a comprehensive understanding of the application environment. To enhance the durability of the bearings and meet the fatigue life requirements of demanding applications, Timken will customize DuraSpexx® bearings to meet customer needs. DuraSpexx® technology offers one or several cost-saving features and enhanced bearing performance. For bearings with an outer diameter of less than 2130 mm, it can be selected according to the following characteristics to organize small batch production. These features include: the use of reinforced materials to reduce the damage caused by steel impurities; ultra-fine Grinding processing, can reduce surface flaking or fatigue when the temperature is too low and the lubricant film is too thin; designed with internal geometric shape, at high load The stress is evenly distributed in the case of and/or eccentricity.
In many cases, rolling mill bearings must be able to operate at high speed and efficiency in heavy and heavily polluted environments. This requires a good seal of the rolling mill bearing. Timken®'s full line of sealed roll neck bearings meets the demanding requirements of rolling mill equipment that successfully combines advanced bearing technology with an effective seal design, allowing users to seal effectively Find the best balance between bearing performance. Sealed bearings can provide many places for the metal rolling industry. For example, the sealing ring reduces the risk of contaminants entering the bearing and causing related damage, thereby improving the reliability of the bearing and prolonging the service life.
Comprehensive and reliable service
In addition, Timken is fully integrated with products and services such as bearings, gears, lubrication, sealing, maintenance, condition monitoring and training for the characteristics of rolling equipment in the metallurgical industry, providing customers with a total solution to help them maximize Improve job performance.
