Beneficial effect:
1. the utility model characterizes the variation of its viscosity by the speed difference of measuring metal bath under the identical suction function and being inhaled into the sampling hut through the long-pending entrance of same cross-sectional, reaches after the balance the different variable density that characterize tested melt of pressure of metal bath top in the sampling hut to finish the imbibition process.Because the melt suction velocity characterizes with pressure change speed in the sampling hut; fusant density finishes gas-liquid with the imbibition process and reaches after the balance that static pressure characterizes in the sampling hut; intermediate link is few, and apparatus structure is simple, need not for the mechanical mechanism setting such as reducing friction, avoiding the protective condition such as vibration.Although fusant density also can produce certain influence to its rate of liquid aspiration (sampling hut's liquid level ascending velocity), but because the utility model can the Accurate Determining sampling hut in static pressure and obtain the fusant density parameter, utilize density value compensation viscosity test result, can realize that fully two-parameter high precision detects.
The utility model is owing to characterize respectively melt viscosity and density by mensuration liquid-column height method after measuring rate of liquid aspiration and imbibition end in the negative-pressure liquid suction process, omit many physical construction and reduce constraint condition, thereby make this proving installation have that test speed is fast, test accuracy is high and testing cost is low.
Viscosity and density are two very important metal bath thermal physical property parameters, and Measurement accuracy viscosity, density is production control process and product quality effectively.Detect simultaneously and rapidly melt viscosity and density and not only can greatly shorten sense cycle, and can reduce testing cost.
