The fundamental possibility of the application of salt lubricants for continuous hot rolling of tubes was confirmed. The best properties are possessed by a lubricant with the following composition 40 zinc chloride, 30 potassium chloride, 30 sodium chloride, 10 of the weight of the salts magnesium oxide and 45 of the salts and filler water. The pickling time for tubes rolled with a salt lubricant decreases twice as compared to that of tubes rolled with graphite-mazut lubricant. It was found that a salt lubricant remaining on the internal surface of tubes promotes general corrosion of the metal of the tubes. The influence of the quantity of the various fillers and components of the lubricant on the melting and crystallization temperatures, and also the influence of the quantity of diluent on the consistency of the lubricant determining the covering ability per unit of surface of the mandrel, were established.
