Description
Technical field
Patent of the present invention belongs to the research field of glass lubricant greasy property when high temperature, goes for the test of other lubricant kinetic viscosity.
Background technology
The Applicable temperature scope of glass lubricant is 900 ~ 1200 ℃, is mainly used in the plastic forming process of high temperature alloy or titanium alloy component.In the hot forming process, the variation of the viscosity with temperature of glass lubricant and changing, can make glass lubricant be in best lubricating effect very important for the shaping of high temperature alloy or titanium alloy component, and the best lubricating effect of glass lubricant depends on its kinetic viscosity, therefore, relation when high temperature between the kinetic viscosity of glass lubricant and temperature, the pressure etc. is one of the major technique that realizes the forming technology of high temperature alloy or titanium alloy component.
Viscosity is an important indicator of glass lubricant, and it plays an important role in the hot extrusion process of steel, usually represents with kinetic viscosity.Kinetic viscosity has characterized the size of fluid viscosity internal friction.Owing to moulds of industrial equipment temperature, the factors such as variation of running time, extrusion temperature has certain variation during hot extrusion, therefore requires the high temperature viscosity of glass to change little in the extrusion temperature scope.Rule of thumb, when hot extrusion, the viscosity of glass lubricant is when 30 ~ 100 Pa.s scope, and lubricant effect is better.Viscosity too hour, the lubricating film anti-pressure ability is poor, and irregular flowing occurs during hot extrusion easily, from the die orifice ejection and consume rapidly.When viscosity was too large, friction factor was too large, does not have lubricant effect.When different steel grades is carried out hot extrusion, because therefore technological parameter (extrusion temperature, extrusion speed) difference must choose suitable glass lubricant, its viscosity and extrusion process are complementary.
Summary of the invention
Purpose of the present invention is exactly curve and the deficiency that exists for overcoming above-mentioned prior art, and a kind of glass lubricant kinetic viscosity adhesion test method and device are proposed, the kinetic viscosity of (more than 1000 ℃) when adopting method and apparatus of the present invention not only can measure high temperature also can be measured the kinetic viscosity of the glass lubricant under the different pressures condition.So that the relation between research kinetic viscosity and temperature, the pressure.
