Application of high-temperature bearings in metallurgical industry

Nov 28, 2023

In the metallurgical industry, high-temperature environments are inevitable. Every link requires high-temperature treatment, from ironmaking to steelmaking to steel rolling and forging. In this process, high-temperature bearings play a vital role.

Ironmaking and Steelmaking

High-temperature bearings are widely used in various mechanical equipment, such as blast furnaces, converters, and electric furnaces, in the ironmaking and steelmaking processes. These devices must operate in high-temperature environments, and high-temperature bearings can withstand this harsh environment.

In the ironmaking process, the blast furnace is one of the core equipment. To enhance blast furnace efficiency and lifespan, workers need a stable operation. High-temperature bearing is one of the critical components of the blast furnace. It can withstand the enormous pressure and temperature generated by the blast furnace during the process and ensure the regular operation of the blast furnace.

Converters and electric furnaces are the leading equipment in the steelmaking process. Converters mainly produce carbon and alloy steel, while electric furnaces especially have stainless and high-strength steel. During the operation of this equipment, high-temperature bearings can withstand high temperatures and substantial impact loads, ensuring the stability and reliability of the equipment.

Steel rolling and forging

In the steel rolling and forging processes, high-temperature bearings are widely used in various rolling mills and stamping machines. These equipment require processing and handling metals in high-temperature environments, and high-temperature bearings can withstand this harsh environment.

In the steel rolling process, high-temperature bearings are used in various rolling mills. These rolling mills require processing and handling metals in high-temperature environments to ensure product quality and performance. High-temperature bearings can withstand this high-temperature environment and ensure the regular operation of the equipment.

In the forging process, high-temperature bearings are used in various forging machines. These forging machines require the processing and handling of metal in high-temperature environments to ensure product quality and performance. High-temperature bearings can withstand this high-temperature environment and ensure the regular operation of the equipment.

Importance

High-temperature bearings are one of the most critical components in the metallurgical industry. Since mechanical equipment in the metallurgical sector must operate in high-temperature environments, approaches that can withstand such harsh environments are required. High-temperature bearings have the characteristics of high-temperature resistance, corrosion resistance, dust resistance, and friction reduction and can meet the requirements of the metallurgical industry.

First, high-temperature bearings can withstand high-temperature environments. Every link in the metallurgical industry requires high-temperature treatment, from iron-making to steelmaking to steel rolling and forging. High-temperature bearings can maintain stable performance and life during this process, ensuring the regular operation of the equipment.

Secondly, high-temperature bearings are resistant to corrosion. Corrosion is a widespread problem in the metallurgical industry. High-temperature bearings have good corrosion resistance and can resist the erosion of various chemical substances, ensuring their service life and performance.

In addition, high-temperature bearings are dust-proof. Dust and impurities are a widespread problem in the metallurgical industry. High-temperature bearings have better dust-proof functions, which can prevent dust and water from entering the inside of the bearing and affecting its regular operation.

Finally, high-temperature bearings also have the characteristic of reducing friction. Friction is a widespread problem in the metallurgical industry. High-temperature bearings can reduce friction inside the bearing through unique designs, making them more stable and reliable in high-temperature environments.

Bearing types for high-temperature bearings usually include deep groove ball bearings, cylindrical roller bearings, tapered roller bearings, thrust roller bearings, spherical roller bearings, etc. These bearing types can maintain stable performance and life in high-temperature environments.

Deep groove ball bearings are a widely applied type of high-temperature bearings. They have deeper raceways and balls and can withstand larger radial and specific axial loads. Cylindrical and tapered roller bearings are also commonly used in high-temperature bearings. They can withstand large and radial-axial loads and have good impact resistance. Thrust bearings are used to bear axial loads with more minor rolling elements and rings and can withstand thrust loads at high temperatures. Spherical roller bearings have better self-aligning performance and can maintain stable operation in high-temperature environments.

In addition to the above common bearing types, there are some special high-temperature bearing types, such as high-temperature sliding bearings, high-temperature spherical bearings, etc. These bearing types have good high-temperature and adaptability and can maintain stable performance and life in high-temperature environments.

In short, high-temperature bearings play an essential role and application value in the metallurgical industry. It can withstand high-temperature environments, resist corrosion, prevent dust, and reduce friction, ensuring the regular operation of equipment and improving product quality. With the continuous development of science and technology, the performance of high-temperature bearings will continue to improve, making more significant contributions to the development of the metallurgical industry
