Abstract
Abstract In the cold rolling oils for steel sheets of the present invention, when 0.2-5% by weight of a high molecular nonionic surfactant having a molecular weight of 2000-15000 and an HLB value of 5-9, as well as 0.2-5% by weight of another nonionic surfactant having 12-16 HLB value, are incorporated with a cold rolling oil as emulsifying and dispersing agents, anti-coalescence of oil particles emulsified and dispersed are remarkably improved, and they are less affected by inclusion of iron powder so that excellent stability with time in an emulsified and dispersed state is obtained, as well as that its plateout is significantly improved. Further, the concentration of the resulting cold rolling oils does not decrease, even in case of weak stirring force, so that stable performance with time are obtained. In addition, when 0.1-10% by weight of an acetylene glycol nonionic surfactant is further incorporated with the above-described cold rolling oils for steel sheets of the invention, adverse effects due to inclusion of iron powder are safely avoided.
