Soap flakes are used in the steel industry (drawing, calibration, stamping, etc.) as technological oil and as a surface active agent.
For drawing of brass, aluminium and steel wire, for manufacturing of pipes, rods and wire of various groups, for nail production, the dry powder lubricants are widely used. The lubricants must provide high wear resistance to the tools as well as required surface quality of products, reducing the coefficient of friction. When traction is performed at high speeds, an effective cooling of tools is needed.
To solve these problems, usually, the soap flakes are used, which is a mixture of sodium salts and fatty salts containing the basic substance from 60 to 88%. Soap flakes are used both in pure forms or mixed forms with other paste-like consistency and olive oils (petroleum jelly, bitumen), vegetable oils, animal fats, powders of metal stearates, etc.
