Tracks: Novel Methods for Enhanced Lubrication in Continuous Casting & Rolling Mill Operations

The rolling of high-strength steels poses enormous demands on coolants/lubricants. Minimum Quantity Lubrication (MQL®) represents a new generation of roll-gap lubrication technologies for cold rolling, which applies minimum amounts of pure rolling oil, finely atomized with pressurized air, directly onto the work roll surface. MQL is successfully installed and commissioned at ThyssenKrupp Steel Europe’s tandem cold mill No. 1 in Bruckhausen. MQL replaces the conventional roll-gap lubrication system with emulsion in mill stands 1 and 2. Additionally, Primetals has modernized the work roll cooling on mill stands 1–3, which resulted in improved cooling performance and drastically reduced emulsion flowrates. The industrial solution concept and impressive results from the first MQL installation will be presented in this paper.
