Embodiment
Below in conjunction with the drawings and specific embodiments the Metal Melting body heat analysis that the utility model provides is elaborated with two quantitative sample cups of chamber double-thermocouple.
As Fig. 1-shown in Figure 2, the Metal Melting body heat analysis that the utility model provides comprises loam cake 1 and two temperature-sensing elements 5 of lower house 3, band dividing plate with two quantitative sample cups of chamber double-thermocouple;
Wherein lower house 3 is the cuboid casing of upper end open, analyzes specimen chamber thereby form the heat that can fill metal bath in the inner space, and depression is formed with two functional material mounting grooves 6 on the bottom surface of heat analysis specimen chamber one side;
The loam cake 1 of band dividing plate covers the upper end open place of lower house 3, the one middle side part is formed with a metal bath sprue gate 4, the opposite side middle part is formed with a vent port 2, the middle part, bottom surface then is formed with a dividing plate 10 along laterally giving prominence to downwards, thereby above-mentioned heat is analyzed specimen chamber be divided into two metal bath specimen chambers 8,9, and between the bottom surface of the lower end of dividing plate 10 and heat analysis specimen chamber corresponding distance is arranged, thereby between metal bath specimen chamber 8,9, form a narrow slit shape siphon groove 7, to guarantee the realization of siphonic effect;
The lower end of two temperature-sensing elements 5 is vertically fixed on the middle part, bottom surface of above-mentioned two metal bath specimen chambers 8,9 respectively.
Described metal bath sprue gate 4 is funnel-form.
Described temperature-sensing element 5 is a thermopair, and the pair-point of thermopair upper end is positioned at 1/2 place of metal bath specimen chamber 8,9 height.
Described vent port 2 is the buttress shaft shape, when covering loam cake 1 on the lower house 3, preferably makes vent port 2 be positioned at the top of functional material mounting groove 6, and a large amount of gases that generate in the time of can making reaction are like this discharged fast.
In addition, can utilize the method for adjusting dividing plate 10 positions that two metal bath specimen chambers 8,9 are arranged to identical or different volume, to realize measurement to specific generation phase content under the different cooling and solidification shrinkage defective volume.
In addition, the loam cake 1 of described band dividing plate and lower house 3 are made by exotic material, and the surface can apply a kind of high-temperature resistant coating of protectiveness, with anti-tamper.
When needs utilize Metal Melting body heat analysis that the utility model provides to carry out the hot analysis to measure of a certain metal material difference in functionality with two quantitative sample cups of chamber double-thermocouple, at first in two the functional material mounting grooves 6 of this Metal Melting body heat analysis, pile one or both functional materials (as oxygenant with two quantitative sample cups of chamber double-thermocouple, reductive agent, alterant etc.), lower end with two temperature-sensing elements 5 is vertically fixed on metal bath specimen chamber 8 respectively then, 9 bottom centre position, and make the pair-point on it be positioned at metal bath specimen chamber 8,1/2 place of 9 height is even pair-point just in time is positioned at two metal bath specimen chambers 8, on 9 the volume center point.To be bonded in the upper end open place of lower house 3 with the loam cake 1 of dividing plate at last, and make the vent port 2 on the loam cake 1 of band dividing plate be positioned at the top of functional material mounting groove 6 on the lower house 3 simultaneously, a large amount of gases that generate in the time of can making reaction are like this discharged fast.At this moment, the metal bath specimen chamber 8,9 of two fixed volume region that are divided into by dividing plate 10 measures specimen chamber as ortho states respectively and the function attitude is measured specimen chamber, and be separately installed with a temperature-sensing element 5 in each metal bath specimen chamber 8,9, can utilize the mode of regulating siphon groove 7 sizes and vent port 2 apertures to control the metal bath that contains functional material is not back in the ortho states measurement specimen chamber, with the measuring accuracy of anti-pollution ortho states metal solution.Afterwards the metal bath sprue gate 4 from the loam cake 1 of band dividing plate originally the attitude metal baths pour into the metal bath specimen chamber 8 that is positioned at its below.Owing to be communicated with siphon groove 7 between two metal bath specimen chamber 8,9 bottoms, therefore the metal bath that pours into will flow in another metal bath specimen chamber 9 by above-mentioned siphon groove 7, to guarantee the liquid level lifting height unanimity of metal bath in two metal bath specimen chambers 8,9.In addition, after script attitude metal bath floods functional material mounting groove 6, the functional material that is positioned at functional material mounting groove 6 inside will produce dissolving and react with script attitude metal bath.After the liquid level for the treatment of metal bath in two metal bath specimen chambers rises to the bottom surface of loam cake 1 of band dividing plate simultaneously, entering metal bath in the vent port 2 will solidify rapidly and should seal, the metal bath at siphon groove 7 places, vent port 2 sealing back also will stop to flow and solidifying rapidly, thereby the metal bath that will contain functional material is enclosed in the metal bath specimen chamber 9, at this moment the metal bath that contains functional material in the metal bath specimen chamber 9 just can't be back in the metal bath specimen chamber 8, therefore also just can not pollute the measuring accuracy of ortho states metal solution.At this moment, the loam cake 1 of band dividing plate in a fixing scope, after this just can adopt the mode identical with prior art that the result who handles through difference in functionality with a kind of metal material in two metal bath specimen chambers 8,9 is measured the metal bath volume defining in two metal bath specimen chambers 8,9.Promptly use the thermal data such as specific heat, crystallization, phase transformation and the rate of heat dispation of sample cup under different temperatures of the temperature-time curve of solidification of metal melt processes in the metal bath specimen chamber 8,9 that two independent temperature sensing elements of acquisition by thermal analysis instrument 5 degree captures and metal bath to calculate the concrete quality of specific phase transformation product exactly, and can report out the volume of defectives such as the concrete content of various solidified structures and shrinkage cavity, shrinkage porosite quantitatively.
