Description
Technical field
The utility model belongs to molten metal and detects analyser, a kind of molten metal specificity analysis of special design sample cup.
Background technology
In Foundry Production, can measure rapidly and accurately in the stokehold chemical constitution, mechanical property, the nodularization rate of molten iron at present, be the key that control determines casting quality.Use microelectric technique and computer technology, in conjunction with hot analysis principle, development improving cast iron quality stokehold device for quick testing is to realize the effective approach of casting quality optimal control.Heat analysis has the characteristics such as test speed is fast, working stability is reliable, and mathematical model is proofreaied and correct the Foundry Works that can be used for different working conditions in the machine through reality.Someone is referred to as the cooling curve in the foundryman's fever analysis in " fingerprint of metallurgical quality ", and the ultimate principle of foundryman's fever analytical technology stokehold fast prediction and forecast casting quality is utilized the cooling curve of thermal-analysis instrumentation record molten iron in specific sample cup exactly.Then come chemical constitution and the mechanical property of quantitative calculating molten iron according to the variation of eigenwert on the cooling curve, or estimate qualitatively graphite form and the Solidification Quality of main body with heat of solidification effect parameter.Quantitative thermal analysis is for the control hot metal composition, and the mechanical performance index of passing judgment on fast foundry goods has practical significance; Qualitative heat is analyzed the important directive significance of Solidification Quality certificate for the control molten iron.Along with the development of Foundry Production, mechanization and automaticity improve day by day, and the main chemical compositions of stokehold Fast Measurement molten cast iron (carbon equivalent, silicon amount, carbon amount) has great significance to the packing casting quality.Conventional chemical analysis method is very time-consuming, needs approximately 15 ~ 20 minutes just can obtain analysis result, although fast spectral analysis is rapid, accurately expensive and equipment is complicated, the stokehold is used and is restricted.And thermal analysis system needed 3 ~ 4 minutes can obtain the result, and expense is cheap, and is easy to operate, and use the specialized Foundry Works stokehold that is particularly suitable for large-lot production.Therefore modern iron foundry (shop) adopts thermal analysis system to control fast the important detection means of molten steel quality as the stokehold more and more, the Castiron Melting quality express-analysis technology of getting up as base growth take statistical science and numerical evaluation, in the research and development course in existing more than ten years of China, its advantage is:
1, testing result has more Practical significance, it is well-known to prevent that the material waste product from occuring, there are graphite element and carbide-forming element in the iron liquid, each element has again different effect degrees under different content, these elements merge mutually, after reacting to each other, again separately effect degree there is counteracting or strengthens.Heat analysis has and can measure the combined action result of individual element in iron liquid, at short notice iron liquid is finished intuitively synthetic determination.In composition detection, quote not to the utmost principal ingredient C, the content of Si and according to C, the carbon equivalent ce C value of Si cubage, and also this parameter of carbon equivalent ce S of measuring shows the combined action of other elements.By contrast CES and CEC value, stokehold control personnel can judge very intuitively that hundred mouthfuls of the liquid that taps a blast furnace are changed and degree of graphitization, in order to take measures in time to adjust, prevent the waste products such as foundry goods generation spoken parts in traditional operas and shrinkage porosite even material be defective.To be that spectral analysis is directly spent in conventional chemical constitution and stokehold incomparable for the advantage of the combined action of various elements in this measurement iron liquid of thermal analyzer.
2, measure simply, quick heat is analyzed from sampling, can measure CES individual in the liquid that taps a blast furnace in three minutes, CEC and C, and Si content, Measuring Time shortens tens times than conventional chemical analysis, shortens more than one times than the straight degree spectrometer in stokehold.Can be completely achieved the On-line Control of iron liquid quality.
3, after the measurement result of iron liquid composition analyser easy to adjust is calculated, computing machine can be according to the target component of setting material, the carburant that automatic calculating need to not add, the weight of ferrosilicon and steel scrap, need not stokehold control personnel and carry out loaded down with trivial details calculating, result of calculation is quick and precisely avoided personal error and unnecessary composition fluctuation.
4, chemical constitution measuring accuracy higher carbon equivalent degree of accuracy can reach 0.1%, and carbon equivalent can reach 0.05%, and silicone content can reach 0.1%.The measurement of temperature all is indispensable in key links such as measuring melting, prepare and shape.In the Metal Melting process, realize the control of composition and metallurgical quality by the control temperature.In the metal freezing, temperature directly affects nucleation, grows up and distributes, and the Measurement accuracy of temperature is the key of solidifying control with control.In the forming materials process, the formation of the defectives such as stowing capacity, contraction and pore is also all directly related with temperature.Thereby accurately and real-time monitoring and effective control temperature are Metal Meltings, moulding by casting and the important step of solidifying control.
This express-analysis technology, wherein one of crucial is to design a kind ofly to guarantee that polarity correctly analyzes connector with heat and link to each other so that response speed is faster, pouring temperature range is broad, cooling curve stability by force, the sample cup that the rate of surveying into is high.
Summary of the invention
The object of the invention is to overcome above-mentioned technical deficiency, provide a kind of and guarantee that polarity correctly links to each other with heat analysis connector, so that response speed is faster, pouring temperature range is broad, and cooling curve stability is strong, the sample cup that the rate of surveying into is high.
The technical scheme that the utility model technical solution problem adopts is: a kind of molten metal specificity analysis sample cup, comprise precoated sand cup (2) and cup socket (7), it is characterized in that fixedly being equipped with one by the U-shaped pipe of interior quartz glass (4) and outer quartz glass (5) formation at the center of precoated sand cup (2), thermopair (3) is housed in the pipe, precoated sand cup (2) is equipped with at thermopair (3) two ends, and the bottom surface of precoated sand cup (2) is provided with groove (8); Internal chamber wall and the end at precoated sand cup (2) are fixed with spoken parts in traditional operas coating (1), and the spoken parts in traditional operas coating (1) the end of on is fixed with a plurality of air chill agent hoof (6).
The beneficial effects of the utility model are, this utility model guarantees that polarity correctly analyzes connector with heat and link to each other, so that response speed is faster, pouring temperature range is broad, and cooling curve stability is strong, surveys into the rate height.
