Abstract
The invention discloses a method and a device for testing an adhesive force of glass lubricant. The device comprises a worktable, wherein a cantilever beam is fixed on one side of the worktable, and a heating furnace is arranged on the worktable. The measuring method of the device comprises the following steps of: (1) putting the glass lubricant between an upper template and a lower template, wherein the upper template and the lower template are parallel; (2) starting the heating furnace 4 to heat the glass lubricant to a temperature of 900-1200 DEG C; (3) gradually increasing weight of a balance weight 10 until the upper template 5 begins to move, and recording an indicating value of a tension meter 1, wherein the indicating value is a tension F value; and (4) counting an adhesive force value of the glass lubricant under a condition that the temperature is 900-1200 DEG C. The method and the device for testing the adhesive force of the glass lubricant have the advantages of simple method, accuracy in measurement and the like; and according to the method and the device for testing the adhesive force of the glass lubricant, the adhesive force of the glass lubricant under the high temperature above 1000 DEG C can be measured.
Description
technical field
The invention belongs to the research field of glass lubricant greasy property when high temperature, go for other lubricant.
Background technology
For the glass lubricant of high temperature alloy pipe extrusion molding, the Applicable temperature scope is at 900 ~ 1200 ℃.In the hot forming process, the adhesion liquid body viscosity of glass lubricant, temperature impact, can make glass lubricant very important for the shaping of high temperature alloy pipe extruding in best lubricating effect, and the best lubricating effect of glass lubricant depends on the technological parameters such as its adhesion, viscosity, temperature, therefore, relation when high temperature between the adhesion of glass lubricant, viscosity, temperature, pressure and other parameters is one of important technology of realizing the high temperature alloy pipe extrusion process.
Glass lubricant adhesion is an important indicator of glass lubricant, and it plays an important role in the hot extrusion process of steel.There is substantial connection between liquid glass lubricant adhesion and viscosity, temperature.Rule of thumb, when hot extrusion, the adhesion of glass lubricant is larger, and lubricant just more easily sticks to the extrusion billet surface, and its lubricant effect is better.Viscosity has obvious impact to adhesion, and the larger adhesion of viscosity is larger.For glass lubricant, the Proper Match relation between the parameter of adhesion, viscosity, temperature, pressure, be one of major technique improved the comprehensive lubricant effect of glass lubricant.
Summary of the invention
Purpose of the present invention is exactly defect and the deficiency existed for overcoming above-mentioned prior art, and proposes a kind of method and apparatus of measuring glass lubricant adhesion when high temperature, so that the relation between research adhesion and viscosity, temperature, pressure and other parameters.
The technical scheme adopted is:
A kind of glass lubricant adhesion testing device, comprise worktable, a side of worktable is fixed with semi-girder, is provided with a heating furnace on worktable, be arranged with cope match-plate pattern and lower bolster in heating furnace in parallel, between cope match-plate pattern and lower bolster, glass lubricant is arranged, be inserted with a thermopair in glass lubricant, the both sides at semi-girder top are equiped with respectively pulley, stay cord is arranged on pulley, one end of stay cord is connected with described cope match-plate pattern, and the other end of stay cord is connected with a mass, is equiped with draw-bar donamometer on stay cord.
A kind of glass lubricant adhesion test method is characterized in that comprising the following steps:
(1) glass lubricant is put between two parallel upper and lower templates; (2) start heating furnace 4, glass lubricant is heated to 900 ~ 1200 ℃; (3) increase gradually the weight of weight 10, until cope match-plate pattern 5 setting in motions, record the reading of draw-bar donamometer 1, i.e. the tensile force f value; (4) the glass lubricant adhesion value of accounting temperature under 900 ~ 1200 ℃ of conditions.
Principle of the present invention:
Apply a tensile force f perpendicular to lower bolster on cope match-plate pattern, start from scratch while increasing gradually when tensile force f, cope match-plate pattern starts mobile, until cope match-plate pattern separates with metal level, reads draw-bar donamometer reading now.Contact area between cope match-plate pattern and glass precursor solution is A, the adhesion of glass precursor solution:
In formula: F is pulling force, N; A is contact area,
; F is adhesion, Pa.
It is simple that the present invention has method, measures the advantages such as accurate, the adhesion of the glass precursor solution in the time of can measuring high temperature more than 1000 ℃.
