  • New Lubrication Technology For The Hot Strip Mill

    Jan 27, 2010 The use of lubrication during hot rolling presents a lot of advantages. One of the main advantages is the considerably high reduction of rolling force, which leads besides the energy saving (up to 15%) to a reduction of roll wear (longer rolling campaigns and roll lifetime). Product surface quality is greatly improved by a decrease of shearing forces in the roll gap
