There are various types of metallurgical equipment, including not only the equipment required for raw material plants, but also equipment needed for steelmaking processes, rolling processes, leveling processes, and other upstream to downstream processes. These devices are equipped with various bearings. These bearings are used under the unique "iron powder", "water", and "hot" working conditions of metallurgical equipment, and also need to meet the conditions of "heavy load vibration impact", "rapid acceleration and deceleration from ultra-low speed to high speed", etc. They are used under very harsh working conditions.

The steel smelting process is extremely demanding, and equipment needs to operate in environments with temperatures up to 3000C, loads of 3000 tons, extremely slow oscillations, peak loads, and vibrations. Every day, it faces high temperatures, large amounts of cooling water, and high impact forces, as well as increasing production requirements and challenges to maintain or even improve product quality. At the same time, operators are also under pressure to reduce unit costs, improve product quality, and reduce environmental impact. For industries where reliable and safe production is no longer easy, such challenges are severe.

Temperature and speed limits, sustained high impact loads, abrasive dust, corrosive chemicals, and high humidity are extreme operating conditions faced by metallurgical factories. It can be said that these are rare challenges in other industries. These operating conditions can cause equipment aging, unplanned shutdowns, and even in better conditions, make effective maintenance difficult. The increasingly strict environmental and health safety regulations also make environmental protection and employee safety a top priority.
