Granular blast furnace slag is interground with amine salts of aromatic group-containing carboxylic acids to enhance the efficiency of the grinding operation. In a preferred embodiment, a mixture of aromatic group-containing carboxylic acids obtained as a low cost by-product in a commercial process to produce phthalic anhydride, is utilized to prepare the amine salt …
Surface finish refers to the process of altering a metal's surface that involves removing, adding, or reshaping. It is a measure of the complete texture of a product's surface that is defined by three characteristics of surface roughness, waviness, and lay. The surface roughness is the measure of the total spaced irregularities on the surface.
