Achievement of high quality of cold drawn sized steel surface as well as its roughness parameters signifi cantly depends on the choice of lubricant which ensures the adjusted friction conditions in the contact zone. Lubricant composition and technological properties appoint its effectiveness in deformation zone at sizing. The results of study the composition and technological properties of powdered lubricant SVS-U used for sizing steel grade 40Cr with special surface finishing are presented in this paper. It was stated that lubricant SVS-U consists from sodium soap and filler materials as sodium sulphate and talc which makes it possible to create stable lubricant film in the deformation zone. The lubricant was estimated in accordance with such technological characteristics as humidity, granulometric composition, melting temperature and thermooxidizing stability. Peculiarities of procedures to study the melting temperature and thermooxidizing stability and data analysis using calorimretric and thermogravimetric curves are presented. The index for estimation the lubricant thermooxidizing stability which makes it possible to determine its workability temperature range is suggested. The results of investigation showed that the lubricant SVS-U exhibits high melting temperature and thermooxidizing stability. Based on the obtained results it was concluded that high quality of sized steel surface could be achieved at using the lubricant SVS-Y at such sizing regimes when temperature in the calibration zone is not higher than 265 °C. As a result of numerical calculation of temperature fi elds at steel sizing the temperature of 241 °C in the calibration zone was defined. Hence, it was approved the eff ectiveness of using the lubricant SVS-U for sizing steel grade 40Cr with special surface finishing in order to achieve the required surface roughness parameters which are regulated by normative documentation on this kind of metal product.
The study has been accomplished at the financial support of RFFR in the framework of project No. 18-58-45008 IND_a.
