Abstract

A water-base lubricant for mandrel contains scale graphite, filming resin, viscosity increaser, water and auxiliary material. Its advantages are high lubricating performance, and uniform and compact film.

Description

Technical field: [0001] The present invention relates to a lubricant. Background technique: [0002] With the continuous development of the domestic steel industry, the rolling process is constantly being updated to improve the physical and chemical properties of steel, reduce labor intensity, and improve product quality. Especially in the rolling of seamless steel pipes, due to the particularity of the rolling process, the changes of various parameters in the deformation zone are more complicated than those of steel plates, so there are more stringent requirements for the rolling process. [0003] In order to effectively control the changes of various parameters in the rolling area, reduce the friction coefficient, and control the uniformity of wall thickness, a high-quality rolling lubricant must participate in the cooperation. At present, most of the lubricants used in the seamless steel pipe manufacturing industry are dry powdered graphite, which is temporarily prepared...
