Abstract
The present invention provides a sampling vessel to be used for analyzing molten metals has a pair of sampling cavities 16, 18 and a sampling sump 22 separated by a first and second partition walls 14, 20 from each other. The upper surface of the first partition wall is provided with 2 first groove 26 so as to guide the melt from the first cavity 16 to the second cavity 18 and the upper surface of the second partition wall 20 is provided with a second groove 28 so as to guide excess melt in the second sampling cavity to the sump 22.
Description
The present invention relates to the sampling container for analysing of motlten metal, more particularly, relate to the used sampling container of composition that heat is analyzed the fused solution of cast iron and steel.
Before the fused solution with cast iron or steel is cast in the casting mold, whether meet the requirements etc. in order to find out metal structure and proterties, check as said stokehold and will carry out hot analytical review.
When the heat of carrying out this motlten metal is analyzed, generally be motlten metal to be taked in the cup-like containers of upper opening with handle spoon etc., this container be to use thermopair is installed the thermotolerance material for example pottery make, the end of thermopair is connected on the self-operated measuring unit of heat analysis usefulness, carries out heat analysis by the cooling curve of analyzing motlten metal.
Put down into patented claim in 5 years and announced a kind of like this technology No. 280664: " when carrying out its heat analysis as test portion; use two containers simultaneously; add a spot of tellurium in the container; another container is not thrown in any additives; according to two containers measurement result separately, judges whether have modulizer or CVization agent in the motlten metal with the part of cast iron fused solution.
When motlten metal is injected this sampling container, not necessarily always be full of by a certain amount of motlten metal.In other words, normally attempt to make motlten metal just be full of edge with container upper end by the practice that makes the motlten metal overflow container, to take a certain amount of test portion, but in injection rate slowly under the situation, the top protuberance of motlten metal and reach a certain amount of more than, in addition, fast under the situation, often not enough in injection rate.
Motlten metal is injected respectively under two situations in the container like this, its motlten metal amount is not a certain amount of, more or less during difference, then can influence its thermoanalytical precision between the two, can not carry out it exactly relatively.
Have, the motlten metal of high temperature is injected into the degree that can overflow in sampling container, motlten metal will splash or become spherical to flow to ground motlten metal when overflowing in the container, and tending to makes troubles to the operator.
The problem that exists when considering in the past container of above-mentioned employing, the object of the present invention is to provide a kind of sampling container for analysing of motlten metal, it has two test portion chambeies, can make the amount of taking of the test portion that the test portion that adds tellurium and measure measures with not adding tellurium become a certain amount of.
In addition, the present invention also aims to provide a kind of sampling container for analysing of motlten metal, it has the motlten metal that can hold by the unnecessary motlten metal test portion that flows out in the test portion chamber and accumulates the chamber.
For achieving the above object, motlten metal sampling container of the present invention is characterised in that: it has two the test portion chambeies in the first test portion chamber and the second test portion chamber and motlten metal accumulates the chamber, accumulate at first and second test portion chamber and the second test portion chamber and motlten metal on the part in the next door between the chamber short slot is set, the a certain amount of above unnecessary motlten metal test portion that injects in the test portion chamber can be got rid of, and the motlten metal of same quantity is taked simultaneously unnecessary motlten metal to be collected motlten metal and accumulate in the chamber in separately the test portion chamber.
Fig. 1 is the planimetric map of the sampling container for analysing of motlten metal of the present invention;
Fig. 2 is II-II cut-open view of Fig. 1;
Fig. 3 is III-III cut-open view of Fig. 1.
Referring to description of drawings most preferred embodiment of the present invention.As shown in Figure 1, motlten metal sampling container 10 is similarly made of heat proof material with sampling container in the past, has the perisporium 12 of thickness to a certain degree.
According to the present invention, container 10 has the first test portion chamber 16 of the same capability that is separated by next door 14 and the second test portion chamber 18 and the motlten metal that separated by the next door 20 and the second test portion chamber 18 accumulates chamber 22.
In first and second test portion chamber separately 16,18, identical in order to detect the temperature of molten metal test portion with common this sampling container, the gauge head 24 that runs through its bottom center and reach specified altitude is installed.
On the next door 14 that separates in the first test portion chamber 16 and the second test portion chamber 18, form first short slot 26 with certain degree of depth, make the motlten metal can be in the first test portion chamber 16 flows to the second test portion chamber 18 by its upper limb with container 10.
Have again,, form second short slot 28 with certain degree of depth, make motlten metal flow to motlten metal and accumulate in the chamber 22 by the second test portion chamber 18 by its upper limb the second test portion chamber 18 and motlten metal being accumulated on the next door 20 that chamber 22 separates.
The sampling container for analysing molten metal 10 of this invention is to constitute as top being described in detail, adds tellurium and the heat analysis of not adding the motlten metal of tellurium in order to study, and tellurium is positioned in one of them test portion chamber in advance.
Then, motlten metal is injected in the first test portion chamber 16, in the first test portion chamber 16, be full of a certain amount of test portion.And then continue to inject motlten metal in this first test portion chamber 16, therefore, motlten metal by the first test portion chamber 16 through first short slot 26, flow in the second test portion chamber 18, when the second test portion chamber is filled to when a certain amount of, unnecessary motlten metal is discharged to motlten metal and accumulates in the chamber 22 via being arranged at second short slot 28 on the next door 20.
Therefore, when using container of the present invention, taking of motlten metal, need special attention, just can in the first test portion chamber 16 and the second test portion chamber 18, inject a certain amount of motlten metal, can precision well and reliably carry out heat analysis, will be collected in motlten metal by the unnecessary motlten metal of the second test portion chamber, 18 outflows simultaneously and accumulate in the chamber 22, can not be splashed on the ground etc.
