Abstract
The utility model discloses a casting alloy thermal analysis device, which belongs to the technical field of casting alloy analysis and detection instruments. The casting alloy thermal analysis device comprises a sanded cup, a quartz tube, thermocouples, a support and dual-hole alundum tube, and is characterized in that the casting alloy thermal analysis device is different from the conventional casting alloy thermal analysis devices, the thermocouples are respectively arranged at the center in the sanded cup and a position approaching the cup wall and are arranged in parallel and disposed in the dual-hole alundum tube which is cased by the quartz tube, the bottom of the sanded cup and the upper portion of the support respectively form a groove structure and a convex projection structure, and the groove structure and the convex projection structure can be engaged or overlapped detachably. The casting alloy thermal analysis device has the advantages of being capable of measuring heat of casting alloys during cooling processes more accurately and increasing analysis precision of casting alloys. In addition, the sanded cup and the thermocouples can be reused so as to reduce cost, and the casting alloy thermal analysis device which can be detached is convenient for use.
Description
Technical field
The utility model relates to a kind of apparatus for thermal analysis, particularly the analytical equipment of using before the casting smelting furnace.Belong to casting alloy analysis and detecting instrument technical field.
Background technology
Apparatus for thermal analysis is a kind of pick-up unit that is used to measure casting alloy stokehold quality and composition, Chinese patent CN85100031A discloses a kind of sample cup for thermal analysis, it includes sand cup, quartz ampoule and thermopair, the center line of its sand cup is vertical mutually with the center line of quartz ampoule, quartz ampoule and cover are inserted in wherein thermopair and pass across the sand cup and be positioned at same horizontal two through holes, and its thermopair adopts nickel chromium triangle-nisiloy high precision type.This sample cup has been widely used in the mensuration of the stokehold quality of casting alloy and composition, but adopt the sample cup of this structure, can't carry out Accurate Analysis to the hot-fluid that produces in the casting alloy cooling procedure, and after once using, the thermopair that inserts wherein is difficult for taking out, thereby must use each the replacing at every turn, and belong to disposable sample cup, improved production cost.
The utility model content
The purpose of this utility model is to provide a kind of can carry out Accurate Analysis to the hot-fluid that produces in the casting alloy cooling procedure, the measurement temperature range is big, the while again can reusable casting alloy apparatus for thermal analysis.
The apparatus for thermal analysis of a kind of casting alloy of the utility model includes sand cup, quartz ampoule, thermopair, support and diplopore alundum tube; It is characterized in that: center and nearly sand cup perisporium place in the bottom of sand cup respectively are provided with a pair of thermopair, and each inserts thermopair the bottom and have in the diplopore alundum tube of two apertures; Diplopore alundum tube outside respectively is with a quartz ampoule; The quartz ampoule of two parallel layouts is fixed in the sand cup by two through holes of sand cup bottom; The upper end closed end of quartz ampoule is positioned at the cavity of sand cup, and is positioned at nearly 1/2 place of sand cup height; The endpoint node of thermopair and quartz ampoule upper end closed end offset; Wherein thermopair passes the center of support upper brace part and two circular holes of side edge are fixed on the support together with inserting to fit over two diplopore alundum tubes in the quartz ampoule; The projection structure of groove structure and protrusion is made on the bottom of sand cup and the top of support structure respectively, and both formation agree with or superimposed self-mountable ﹠ dismountuble structure mutually.
Described sand cup is that cylindrical cup or cross section are trapezoidal cube cup.
Described thermopair is a platinum rhodium-platinum thermocouple.
Compared with prior art, the utlity model has following advantage and technique effect: adopt casting alloy apparatus for thermal analysis of the present utility model, can carry out Accurate Analysis to the hot-fluid that produces in the casting alloy cooling procedure, measure the temperature difference that occurs in the diverse location cooling procedure, thereby can judge the variation of alloying component and precipitated phase according to the difference of temperature.Its thermopair is reusable simultaneously, has reduced cost and can improve the reappearance of measurement.And the employing platinum rhodium-platinum thermocouple, measurement range is big, and stability is high, has improved measuring accuracy.During use, only need the sand glass holder is got final product on support, easy to use.
