Investigation of Efficiency of Use of High-Temperature Greases in Steel Rolling - Part 2

摘要

We investigated the friction coefficients (steel-to-steel) for various rolling pressures on application of consistent anti-wear, antiwelding, and metal-cladding greases and 11 metal-working coolants. The protective grease XADO (Ukraine) and import anti-wear greases Mol Favorit-2, Shell Albida, and Mobil 461 were found to be effective in steel rolling. The greases containing molybdenum disulfide don't have high greasing properties in steel rolling, i.e. at plastic deformations of steels. The surface-active substances PEG-4 (Rapeseedamine) and polyoxyethylene alkylether of carboxylic acids (AKYPO RO 90 and AKYPO RO 20) are suitable for creation of new technological metal-working coolants for steel rolling. Considerable decrease in friction coefficient is observed in steel rolling at use of a technological liquid "Universal-1TC".
