<div>In the iron and steel industry large amounts of fine granular bulk material like iron ore fines, fluxes, foundry sands or residues from off-gas dedusting have to be handled. In storage, conveying and handling of such materials wall friction between the particles and the wall material is an important parameter. Recently, it was demonstrated that coatings made of diamond-like carbon (DLC) applied on the surface of the wall material can reduce the wall friction angle with fine granular bulk material substantially. In this study, wall friction angles of different wall materials with various fine granular bulk materials from steel mills were investigated. The results showed a significant reduction of the wall friction angle by the DLC coating in comparison to uncoated steel of up to more than 10°, while other coatings showed comparatively little reduction in wall friction.</div>
