Abstract
The utility model discloses a method for measuring the high-temperature viscosity of liquid solder. The device comprises a tubular furnace with a quartz lining tube, wherein a furnace plug is arranged at an inlet of the tubular furnace; a nitrogen outlet is formed in the furnace plug; a nitrogen inlet is formed in the furnace wall, opposite to the furnace plug, of the tubular furnace. The device is characterized in that a graphite block is horizontally placed in the tubular furnace; a groove is formed in the upper part of the graphite block; a graphite sheet is slidably placed in the groove and is connected with a transverse dynamometer outside the tubular furnace through a drawn wire. The device has the advantages of simple structure, low cost, convenience in operation, high self stability, difficulty in external interference, intuitive measurement process and wide applicable temperature range; the temperature can be kept constant.
Description
Technical field
The utility model relates to liquid metal device for measuring viscosity, especially relates to a kind of liquid solder high temperature viscosity measurement mechanism.
Background technology
Viscosity is determining the hydrodynamics characteristic of liquid metal, is one of Important Property Parameters of liquid metal, and the measurement of viscosity is widely used in metallurgy industry.The packing material of using when solder is soldering, brazing member relies on the solder of fusing to couple together, the performance of solder self and and mother metal between interaction determined to a great extent the performance of soldered fitting, so the quality of soldered fitting depends primarily on solder.The assay method of relevant liquid solder high temperature viscosity is many, and typical classic method has capillary tube technique, rocks vibratory drilling method, falling ball method, rotary process etc.Owing to adopting capillary tube technique, rock vibratory drilling method, during the basic skills test such as falling ball method and rotary process, need to gather the small physical quantitys such as liquid solder natural flow time or suspension torsion angle, falling sphere time and velocity variations, and require testing apparatus very accurate, also very strict to working environment requirement in application, no person measures just inaccurate.Particularly for liquid solder high temperature viscosity, detect, under the specific condition of high-temperature work environment, many method of testings have been subject to restriction to a certain degree when commercial production real time monitoring.
Summary of the invention
The utility model object is to provide a kind of liquid solder high temperature viscosity measurement mechanism of realizing various solders Quick Measurement under different temperatures.
For achieving the above object, the utility model can be taked following technical proposals:
Liquid solder high temperature viscosity measurement mechanism described in the utility model, comprise the tubular furnace with quartz liner, inflow point at described tubular furnace is provided with stove plug, and described stove offers nitrogen outlet beyond the Great Wall, on the tubular furnace furnace wall corresponding with described stove plug, offers nitrogen inlet; It is characterized in that: in described tubular furnace, horizontal positioned has top to offer the graphite block of groove, in described groove, slide and be placed with graphite flake, described graphite flake is connected with the horizontal dynamometer being placed in outside tubular furnace by wire drawing.
The utility model advantage is simple in structure, and cost is low, and easy to operate and self good stability, is not subject to external interference, and measuring process is directly perceived, and Applicable temperature scope is wide, and can keep constant temperature.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, liquid solder high temperature viscosity measurement mechanism described in the utility model, comprises the tubular furnace 2 with quartz liner 1, in the inflow point of tubular furnace 2, is provided with stove plug 3, on stove plug 3, offer nitrogen outlet 4, on the tubular furnace furnace wall corresponding with stove plug, offer nitrogen inlet 5; In the interior horizontal positioned of tubular furnace 2, have top to offer the graphite block 6 of groove, in groove, slide and be placed with graphite flake 7, graphite flake 7 is connected with the horizontal dynamometer 9 being placed in outside tubular furnace 2 by the thin wire drawing 8 of conduction heat-resisting alloy.
While measuring certain solder viscosity, tested solder 10 is put into the groove of tubular furnace 2 graphite blocks 6, graphite flake 7 is placed in to the top of solder 10, first in tubular furnace 2, pass into nitrogen, after inner air is all discharged, heating solder 10 is melted to the temperature of appointment, with horizontal dynamometer 9, with certain speed, draw graphite flake 7, it is slided along groove, read the shown pulling force of horizontal dynamometer 9, be used for characterizing the high temperature viscosity of liquid solder; For preventing solder 10 oxidations in heating and measuring process, in tubular furnace 2, need to continue logical nitrogen protection.
