The Operating Challenges in the Metallurgical Industry and the Core Value of Split Bearings
Core equipment in the metallurgical industry, such as converters, continuous casting machines, rolling mills, and heating furnaces, operate under extreme conditions of high temperature, heavy load, dust pollution, and frequent impact loads. For example, continuous casting machine guide rolls must withstand continuous heavy loads under temperatures exceeding 180°C and spray cooling conditions; rolling mill work rolls face instantaneous impact loads and eccentric shaft operation; and converter support bearings must withstand dust erosion and alternating loads. Traditional integral bearings face three major challenges in these scenarios: installation and maintenance require disassembling the entire equipment, resulting in downtime of several days; ordinary materials are susceptible to high-temperature oxidation and accelerated wear, with a lifespan generally less than 6 months; and insufficient sealing performance leads to frequent failures due to dust intrusion. The modular design of split bearings precisely solves these problems—installation and replacement can be completed without disassembling the shaft system and frame, improving maintenance efficiency by over 60%; and their self-aligning and impact-resistant structural characteristics allow them to withstand the harsh operating conditions of metallurgical equipment. AMUS, a professional brand deeply rooted in the industrial bearing field, offers split bearings customized for the metallurgical industry. These bearings, while retaining fundamental advantages, achieve performance upgrades, becoming a core support for cost reduction and efficiency improvement in steel enterprises.
Key Application Scenarios of AMUS Split Bearings in the Metallurgical Industry
1. Continuous Casting Machine: Stable Protection Under High Temperature and Heavy Load
The guide rollers and drive rollers of continuous casting machines are high-risk areas for bearing failure. Traditional bearings, due to high-temperature deformation and lubrication failure, have an average lifespan of only 3-4 months, and replacement requires disassembling the guide roller assembly, resulting in 8-12 hours of production line downtime. AMUS’s split self-aligning roller bearings, developed specifically for continuous casting machine conditions, utilize special high-temperature resistant alloy steel and an optimized raceway design, achieving a temperature resistance limit of up to 220℃, far exceeding the industry standard of 180℃. Their integrated sealing structure effectively prevents the intrusion of sprayed water mist and molten steel splashes. Combined with long-life grease, a single bearing set can operate continuously for 18 months without maintenance, extending its lifespan by more than 30% compared to similar products. A case study from a large steel plant shows that after adopting AMUS split bearings, the failure rate of guide rolls in continuous casting machines decreased by 75%, and the annual maintenance cost of a single continuous casting line decreased by 400,000 yuan.
2. Rolling Mill System: Highly Efficient Adaptation to Impact Loads
The work rolls and support rolls of hot and cold rolling mills must withstand radial loads of up to several thousand kN and instantaneous impacts, while also adapting to slight shaft misalignment. AMUS split cylindrical roller bearings feature a double-web thickened outer ring design and precision roller geometry, dispersing contact stress and improving impact resistance by 25% compared to industry standards. The spherical bearing housing allows for ±1.5° self-aligning compensation, perfectly adapting to shaft deformation during rolling mill operation. More importantly, its split structure allows for bearing replacement without disassembling the rolls and frame, completing the entire replacement in just 2 hours, reducing maintenance time by 80% compared to traditional bearings and avoiding millions of yuan in economic losses caused by prolonged rolling line downtime. 3. Converters and Heating Furnaces: Durability Guaranteed in Harsh Environments
3. Converters and Heating Furnaces: Durability Guaranteed in Harsh Environments
The bearings of converter support rings and heating furnace conveyor rollers are exposed to harsh environments of dust and high-temperature flue gas corrosion for extended periods, requiring extremely high sealing performance and corrosion resistance. AMUS split bearings utilize a Corrotect® anti-corrosion coating and a multi-labyrinth seal structure, effectively resisting the corrosion of dust, high-temperature gases, and condensate, offering three times the corrosion resistance of ordinary bearings. In terms of materials, they employ high-strength ductile iron bearing housings and alloy carburized rolling elements, achieving a hardness of HRC60 or higher, significantly enhancing wear resistance. Data from a steel plant’s converter application shows that AMUS split bearings operated continuously for 24 months without failure, doubling the lifespan of the previously used brand, and increasing overall equipment efficiency by 15%.
AMUS Split Bearings’ Core Technological Advantages: Why is it the Preferred Choice in the Metallurgical Industry?
