The paper compares energy consumption during cold rolling on a 4-stand mill 1680 of carbon steel assortment using "Quakerol" and "Universal-1TS" lubricating-cooling emulsols. The object of the study was the manufactury process for cold rolled strips in the cold rolling shop. The subject of the study were regularities of the technological conditions influence for cold rolled strips production on a four-stand mill 1680 with the use of "Quakerol" and "Universal-1TS" emulsions on the rolling energy and power parameters. It was found that the average total load on mill's stands motors and winder when using "Quakerol" emulsion is on 4.19% higher than when rolling the same assortment rolled with emulsion from "Universal-1TS". It is shown that the total specific consumption of electricity when rolling on an emulsion prepared from the experimental "Quakerol" emulsol is 2.7% more than rolling on an emulsion prepared from the serial "Universal-1TS" emulsol. The assumption is substantiated that higher specific power consumption in the operation of lubricant-coolant from experimental emulsols, which has a higher saponification number, can be the cause of incorrectly selected and emulsion underestimated concentration in order to reduce the emulsol consumption for the rolling process. It was established that the total consumption of the "Quakerol" emulsion was 0.151 kg/t of rolled product, and it was found that the duration of use before replacement of the experimental emulsion "Quakerol" is in 2.17 times more than that of the "Universal-1TS" emulsion.
