Abstract
The utility model relates to a thermal analyzing device, in particular to an analyzing device before fusing the stove for founding alloy, which belongs to the processing technique field for founding alloy. The utility model comprises a sand sleeve, a quartz tube, a thermo electric couple and the bracket. The raised part of the upper surface of the bracket and the concave part on the bottom of the sand sleeve are cooperated in a moveable manner, and the outside surface of the bottom of the sand sleeve and the upper surface of the bracket are against with each other. The quartz tube is a hollow tube with one end sealed, and the quartz tube is positioned in the sand sleeve through the through hole at the bottom of the sand sleeve and the sealed end is positioned in the cavity of the sand sleeve. The double hole alundum tube and the thermo electric couple through the alundum tube are all through the round hole on the bracket and inserted to the quartz tube. The end node of the thermo electric couple and the sealed end of the quartz tube are against with each other. For the analyzing device for founding alloy afforded by the utility model, the thermo electric couple can be repeatedly used, which reduces cost and can improve the reproductivity of the quality. When in use, the sand sleeve is only needed to sleeve on the bracket with convenient use.
Description
Technical field
The utility model relates to a kind of apparatus for thermal analysis, the analytical equipment of using before particularly a kind of casting alloy smelting furnace.
Background technology
Apparatus for thermal analysis is to be used to measure the stokehold quality of casting alloy and a kind of pick-up unit of composition, Chinese patent CN85100031A discloses a kind of sample cup for thermal analysis, it includes sand cover, quartz ampoule and thermopair, the center line of its sand cover and the center line of quartz ampoule are vertical mutually, quartz ampoule and cover are inserted in same horizontal two through holes that are positioned at that wherein thermopair passes across the sand cover, 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 adopts the sample cup of this structure, 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 and can reuses, and it is big to measure temperature range, and improves the casting alloy apparatus for thermal analysis of measuring accuracy.
For achieving the above object, the utility model is taked following technical scheme:
A kind of casting alloy apparatus for thermal analysis comprises sand cover, quartz ampoule, thermopair, it is characterized in that sand cover bottom cooperates with a support is movable; Quartz ampoule is the hollow tube of end sealing, and this quartz ampoule is fixed in the sand cover by the through hole of sand cover bottom, and its blind end is positioned at the cavity of sand cover; A diplopore alundum tube is fixed on the support together with the thermopair that passes the diplopore alundum tube passes the circular hole on the support, and inserts in the quartz ampoule, and the endpoint node of thermopair and quartz ampoule blind end offset.
The axis of the axis of above-mentioned quartz ampoule and sand cover overlaps.
The above-mentioned sand cover and the movable fit structure of support are: an annular convex ring slip inserting of an annular groove and rack upper surface is arranged at sand cover bottom.
Above-mentioned sand cover is that upper shed is greater than circular cup of going to the bottom or square cup.
Above-mentioned thermopair adopts platinum rhodium-platinum thermocouple, and its endpoint node is positioned at the center of sand cover.
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, its thermopair is reusable, 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, improves measuring accuracy.During use, only need be enclosed within the sand cover on the support and get final product, and are easy to use.
