kuyu-surface finishing tapes and strips, which meets the sanitary-pygienic requirements.

The goal of the goal is achieved by the fact that the smaac ' on the basis of the mineral oil and dialkyl dithiophosphate of cic additionally contains transnomerized refined vegetable oil, tributyl phosphoric acid and 4-methyl-2,6-dig / e-butylphenol.

In the dry SOTS, trans-isomerized refined vegetable oil was introduced to ensure optimal friction conditions for 1 between the rolled strip and work rolls, between the water and idle support rolls; tributyl

phosphate ester helps to improve the surface finish of the rolled metal; zinc salt of dithiophosphoric acid (additive CDDF) provides anti-scuff, anti-wear, anti-corrosion properties; 4-methyl-2,6-di-gregbutylphenol provides thermo-oxidative stability of the composition during long-term operation. As a mineral oil can be used

oil with a viscosity of 3-22 cSt at 50 ° C, which provides the necessary viscosity properties, cooling ability, filterability in the circulation and regeneration system of the coolant heat circuit system.

In the process of preparing SOTS, the above components are introduced into the base oil at a temperature of 50-80 ° C and constant stirring in the above order. The composition of the coolant specimens is given in table. one.

Specimen samples for complex testing of bearings (bearing 406203 E, speed 1440 load 1400 kg). The data are presented in Table. 3. TsNIICHM when rolling a blade tape from steel 6X13. Rolling conditions: the initial tape is negative, pickled, thick, a different 0.3 mm, setting the rolls is constant, the surface roughness of the rolls of class 10. The data are presented in Table. 4. Note. Initial surface roughness of the tapes. The obtained p-results indicate high lubricating, shielding and technological properties of the proposed lubricant, which ensures high quality of the treated surface. Thus, the application of the proposed lubricant made it possible to ensure the production of strips and tapes on various steels and alloys with high surface finish, to increase the productivity of multi-roll mills, to increase the operational durability of high-performance expensive deficient bearing subs and mill rolls, to increase the service life of a cell, and also to improve sanitary and hygienic conditions of labor of workers and environmental protection.
