“…В статье [19] предложена методика ускоренных стендовых испытаний канатов на износостойкость и показано, что периодическое воздействие коррозионноактивной среды многократно уменьшает износостойкость стальных канатов различных конструкций, в которых ни сердечник, ни пряди, ни канат в целом не смазывались и не пропитывались смазочными материалами.…”

The paper compares the results of endurance tests of steel ropes manufactured in accordance with GOST 2688-80, according to the standard method (GOST 2387-80 "Steel ropes. Endurance test method") without exposure to an aggressive environment and the test results according to the developed extended method, taking into account operating conditions in corrosive environments, in particular marine and freshwater environments. It was found that the periodic impact of sea water on the rope many times (from 2.5 to 9.5 times) reduces the wear resistance of the rope, depending on the lubricant used, when compared with tests according to the standard method and proportionally reduces its technical resource. It is shown that the impact of fresh water, as well as sea water, greatly reduces the wear resistance of the rope, but in somewhat smaller limits. On the basis of experimental studies, it has been shown that the compositions of lubricants, which ensured the maximum wear resistance of the rope according to the tests according to the standard method, showed the worst results when tested with the action of sea water. In this regard, it can be stated that the standard technique does not allow accurately predict the durability of ropes under special operating conditions (in sea and fresh water), which can lead to unreasonable, more than 9 times, reduction of the life of the rope. The complex of the studies carried out showed that when testing steel ropes for endurance, as well as when choosing the most effective rope lubricant, one should give preference to the test results according to the method proposed in the work, which takes into account the effect of a corrosive environment.

The paper presents the results of a comparative analysis of methods for testing the low-temperature properties of rope lubricants. Studies have shown that the designation of the temperature range for the use of the rope must be carried out taking into account the low-temperature properties of the rope lubricant used in its manufacture, determined in accordance with GOST 20458-89. The use for these purposes of the instructions of GOST 11507-78 or EN 12593 : 2007, which are intended for testing the low-temperature properties of bitumen, can lead to a significant unjustified reduction in the service life of the rope, since the test method according to the European standard provides for static loading of the sample film applied to the steel plate during its bending, and according to the Russian state standard, shock loading of the sample is provided, which, according to the authors, is closer to the real operating conditions. It is shown that the maximum effect of increasing the wear resistance of the rope at low temperatures is given by the lubricants having the best low-temperature properties determined by the standard method, which is confirmed by the complete correlation of the comparative results of testing the low-temperature properties and wear resistance of the rope at low temperatures. The authors have experimentally confirmed that the highest wear resistance of the rope at low temperatures is provided by lubricants, which have the best low-temperature properties, determined in accordance with GOST 20458-89. It has been established that lubricants, which have unsatisfactory lowtemperature properties, significantly reduce the service life of ropes that are operated at low temperatures, in some cases even with respect to an unlubricated rope. The authors suggest that at low temperatures the components of the lubricant crystallize, the resulting crystals play the role of abrasive elements contributing to accelerated abrasive wear of the wire surfaces.

The paper objective is to find out the effect of various lubricants on the wear resistance of galvanized steel ropes manufactured according to GOST 2688-80 Two lay rope type LK-R construction 6 19(1 +6+6/6)+ 1 o. c. Dimensions. The research was carried out on a machine manufactured according to GOST 2387-80 Stell Ropes. Method of Endurahce testify under normal conditions, at negative temperatures and under periodic exposure to seawater. It is shown that many rope lubricants used by Russian metallurgical enterprises for impregnating galvanized steel ropes, when periodically exposured to seawater, reduce their wear resistance from 16 to 34% in relation to non-lubricated ropes. Only the universal rope lubricant Rosoil-K112 showed an increase in the wear resistance of galvanized steel rope by 23%. It was found that lubricants that maximize the wear resistance of galvanized steel rope during its operation in normal climatic conditions turned out to be completely ineffective at negative temperatures or when exposured by seawater. As a result of the work carried out, it was revealed that in order to increase the wear resistance of galvanized steel rope, additional studies are needed to investigate the interaction of galvanized coating and lubricating material under conditions of periodic exposure to seawater, as well as industrial tests of galvanized steel rope lubricated with universal rope lubricant Rosoil-K112.
