Title:

SEIZING INHIBITOR FOR HOT PLASTIC WORKING OF STEEL

Document Type and Number:

WIPO Patent Application WO/2006/106637

Kind Code:

A1

Abstract:

A seizing inhibitor for the hot plastic working of steels which comprises an inorganic ingredient as a first ingredient, sodium hydroxide as a second ingredient, a water-soluble resin and/or water-soluble surfactant as a third ingredient, and water. The contents of the first ingredient, second ingredient, and third ingredient are 96.5-99.98 wt.%, 0.01-2.0 wt.%, and 0.01-1.5 wt.%, respectively, based on the sum of the first, second, and third ingredients. The inorganic ingredient comprises one or more members selected from the group consisting of Al₂O₃, SiO₂, CaO, B₂O₃, K₂O, and Na₂O. The seizing inhibitor is satisfactory in the property of wetting steels and surface fixability. After application, the seizing inhibitor forms a coating layer tenaciously adherent to the steel. This layer does not peel off during cold and hot working.
