Lubricant with great lubricating performance

Abstract

The invention discloses a lubricant with a great lubricating performance. The lubricant is prepared from, by weight, 40% of talcum powder, 0.8% of sodium carboxymethyl cellulose, 0.7% of diatomite, 9%of sodium pyrophosphate, 6% of aluminum stearate, 15% of borax, 18% of polyethylene glycol, 1.6% of glycerol monostearate and the balance water. The lubricant has advantages that the problem of highfriction coefficient of graphite-free lubricants is improved, and an environment-friendly water-based clay lubricant which is uniform in dispersion, easy to spray, resistant to high temperature, effective in lubrication, easy in cleaning and free of pollution is provided for hot-rolling seamless pipes.

Description

technical field [0001] The present invention relates to lubricants with good lubricating properties. Background technique [0002] Mandrel lubrication is an important part of metal plastic processing in hot-rolled seamless steel pipes. When hot-rolled steel pipes pass through the mandrel, it can improve the elongation coefficient and surface finish of the rolled pipe, prolong the service life of the mandrel and reduce the rolling pressure. As well as energy consumption, reducing or avoiding rolling accidents, all countries in the world are constantly improving mandrel lubricant technology. At present, the treatment of hot metal surfaces is mainly through water-based graphite lubricants, but many hidden dangers (such as electrical conductivity, difficult to clean, and heavy pollution) brought by it have attracted increasing attention. There have been a series of research programs on graphite-free lubricants, but there are still some problems with their relative lubricating p...
