Description

[Detailed Description of the Invention] (Technical Field of the Invention) The present invention relates to a molten metal sampling device for collecting a sample by scooping up molten metal.

(Prior technology) This type of sample collection device was developed in the 1970s.
Various products such as No.-26151 are known, but there is room for improvement in terms of ease of manufacture, ease of taking out samples after collection, etc.

(Purpose of the invention) The object of the present invention is to solve the above-mentioned conventional problems and provide a molten metal sampling device that is easy to manufacture and easy to take out the sample after sampling.

(Embodiments of the invention) The molten metal sampling apparatus of the invention (hereinafter referred to as the sampling apparatus of the invention) will be described below with reference to the embodiments shown in the drawings.

1 to 3 show the sampling device of the present invention,
The sampling device has a sampling container 1 provided with a main part 2 and a secondary part 3 which are laterally adjacent to each other.

The collection container 1 is made by shell molding, in which sand grains are bound together with a synthetic resin binder (for example, phenolic resin) and molded.

The collection container 1 is divided vertically into a pair of halves 1.
It is formed by adhering parts a and 1b to each other with a heat-resistant adhesive.

Next, a storage chamber 5 having an opening 4 upward is formed within the main portion 2 .

In the illustrated embodiment, a constriction throat 19 is formed in the opening 4 to prevent the flowing molten metal from spilling and to separate unnecessary ends (with burrs, etc.) of the solidified metal sample at the constriction throat 19. Efforts are being made to facilitate direct pressure feeding through pneumatic pipes.

A chiller 9 such as a steel block is attached to the storage chamber 5 (in the illustrated embodiment, it is attached to the bottom).

On the other hand, a holding rod 8 is attached to the holding rod path 6 of the sub-portion 3, and one end of the holding rod 8 is integrally or fixedly attached to the chiller 9 in the illustrated embodiment.

If one end of the holding rod 8 is integrated or fixed to the chiller 9, the cooling capacity (its volume) of the chiller 9 can be substantially increased, which is desirable.

Next, the other end of the holding rod 8 protrudes above the sub-portion 3,
As shown in FIG. 3, it is inserted and fixed to the lower end of the handle 10.

In the illustrated embodiment, the handle 10 is made by covering a core material 11 such as a metal pipe with an outer skin 12 such as a paper tube, and the lower end thereof forms a holder 13.

On the other hand, the opening 4 is closed with a lid 14.
In the illustrated embodiment, it consists of an outer material 15 such as a paper board and an inner material 16 such as an iron plate.

In this way, the lid 14 is attached to the outer material 15 and the inner material 16.
If a heavy structure is used, the surface will burn and become thinner as in the case of only paper plates, and when the molten metal flows in, the carbonized paper plates will be mixed into the molten metal flow, causing errors in measuring the carbon content, or as in the case of only iron plates. This is preferable because problems such as slag easily adhering to the surface are less likely to occur, but this does not mean that it is impossible to collect the slag without doing so.

Depending on the on-site usage conditions, it is also possible to use a single-layer lid made of paper board or iron plate.

The method of manufacturing and using the sampling device of the present invention shown in the above embodiments is as follows.

First, as for the manufacturing method, as shown in FIG.
Glue them together with heat-resistant adhesive.

Next, as shown in FIG. 3, the protruding end of the holding rod 8 is inserted and fixed into the lower end of the handle 10.

Next, a lid 14 consisting of an outer material 15 and an inner material 16
is attached to the opening 4 and the opening 4 is closed.

The method for using the collection device completed as described above is as follows.

That is, the operator holds the handle 10 and immerses the collection container 1 into the molten metal to be collected from above.

When the collection container 1 is submerged and the lid 14 is immersed in the molten metal, the lid 14 is melted (the lid 14 is for preventing slag on the surface of the molten metal from flowing in).

As a result, the molten metal flows into the storage chamber 5 through the opening 4 and fills the storage chamber 5.

In the storage chamber 5, the molten metal is removed with heat by the chiller 9 and solidified.

The solidification of the sample in the collection container 1 of the shell mold is delayed due to the insulation effect of the container, and as a result, there is a risk that cavities may occur in the sample or segregation of components may occur, but the cooling effect of the chiller 9 does not It is useful for preventing the occurrence of segregation, cavities, etc. in solidified samples.

After collecting the sample, the operator pulls up the collection container 1 and applies an impact to the collection container 1.

Since the collection container 1 is made of shell mold, it becomes brittle due to the high temperature of the molten metal at the time of collection, and is extremely easily disintegrated by impact.

As a result, the solidified metal sample is taken out and used for spectroscopic analysis or the like.

Here, the core material 11 of the handle 10, the holding rod 8, and the chiller 9 can be reused.

(Effects of the invention) The embodiments of the molten metal sampling device of the invention are as described above, and the effects thereof are listed below.

(1) The collection device of the present invention has the configuration described in the claims for utility model registration, and in particular, the collection container is made of shell mold and is formed by gluing a pair of halves divided into two pieces, so its manufacture is difficult. It's extremely easy.

(2) The sampling device of the present invention has the same configuration as above, and in particular, since the sampling container is made of shell mold, it collapses upon impact after sampling, and as a result, it is extremely easy to take out the sample after sampling.

(3) The sampling device of the present invention has the same configuration as above, and in particular, the sampling container is made of shell mold and is not covered with paper, etc., so when immersed in molten metal, no splash occurs and worker safety is ensured. At the same time, there is no need to worry about hot water spilling due to boiling vibrations.

(4) The collecting device of the present invention has the same configuration as above, and in particular, since a holding rod is attached to the sub-portion of the collecting container, the collecting container is reinforced by the holding rod, and as a result, the molten metal can be reliably collected in terms of strength. It can be collected.
