61. Wear and oxidation behavior of cast high-speed steels used for work rolls in hot rolling mills

Maximilian Reiter (Eisenwerk Sulzau-Werfen R. & E. Weinberger AG, Tenneck, Austria)

Rolling of long and flat product

Oral Presentation

Cast high-speed steel (HSS) work rolls are used in roughing and finishing stands of hot rolling mills, as they possess high hardness and wear resistance, which is responsible for their great durability in service. During the rolling process, depending on the operating conditions in the respective stand, the degradation of the work rolls is caused by a combination of thermal fatigue, rolling...

100. PERT GRINDING BALL ROLLING MILL

Mr NICOLA TOMBA (PERT SRL)

Rolling of long and flat product

Oral Presentation

Nowadays grinding balls production process is mainly done by casting or by pressing, processes which involves anyway low productivity and poor quality on finished products.
PERT has developed a new revolutionary rolling mill to produce high quality grinding balls by rolling process, starting from a round bar coming from upstream bar mill rolling.
Round bars are heated up by a traditional...

72. Sustainable repairs of machine parts in rolling mills by advanced coating technologies

Jens Igel (SMS Group)

Rolling of long and flat product

Oral Presentation

Machine parts, like chocks, rollers, HGC cylinders or gearbox housings, are the backbone of every rolling operation for section and flat rolling mills. They are essential for the delicate production process and ensure perfect product quality, tolerances and dimensions. However, rough operating conditions, such as elevated temperatures, corrosive media, high static/cyclic loads and abrasion,...

172. Advanced manufacturing and improved performances of hot rolling mill edger rolls (EdgerRolls)

Mr Jurgen Malbrancke (CRM Group)

08/10/2025, 12:10

Rolling of long and flat product

Oral Presentation

As the time between roll changes is continuously increasing due to improved performances of roughing rolls, a newer problem is that the performance of the edger roll becomes a bottleneck inducing strip defects crises and mill (unplanned) stoppages only to change the edger rolls. Additionally, worldwide the supply of edger rolls is becoming a problem. Especially for European hot strip mills...

15. On The Performance of Implementing Pre-conditioned Oxide Film of HSS Rolls in A Hot Strip Mill

ZHI ZHANG (BAOSHAN IRON&STEEL CO. LTD)

08/10/2025, 12:30

Rolling of long and flat product

Oral Presentation

Hot strip mills require higher-quality, incident-free rolls to enhance productivity in the production of technical strips with stringent surface quality requirements. This necessitates rolling engineers to innovate new operational designs. The spin-cast HSS grade roll, engineered in Europe, stands as one of the most advanced grades developed over decades. Despite being a mature product, there...
