Description

[Detailed description of the invention] The present invention relates to a white pigtail sampling device for collecting white pigtail samples used for spectroscopic analysis, etc., and provides a white pigtail sampling device that can sufficiently whiten pig iron and perform accurate spectroscopic analysis. With the goal.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The white pig iron sampling device of the present invention (hereinafter referred to as the device of the present invention) will be described below with reference to embodiments shown in the drawings.

FIG. 1 shows a device according to the present invention, which has a sampling mold 7 attached to the tip of a main body 1 made of a paper tube or the like.

The sampling mold 7 is a half body 7 made of metal such as cast iron, steel, copper, etc.
a and 7b, and is in contact with a cooling metal 15 made of metal such as cast iron, steel, copper, etc. at the upper side.

Inside the sampling mold 7, runners 8 that open at the lower end are provided at the top and bottom, and the runners 8 have a plurality of partitions 10,
It has 11.

The runners 8 and the partitions 10, 11 are the runners 8a, 8b, 8c, 8d of the halves 7a, 7b as shown in FIG.
and partitions 10 and 11.

A disk-shaped collection chamber 13 is provided above the runner 8 and communicates with the runner 8, and the collection chamber 13 includes the halves 7a, 7.
b and is surrounded by a cold metal 15.

Next, an introduction pipe 6 made of a heat-resistant material such as a metal pipe such as iron or a quartz pipe is fixed to the opening at the lower end of the runner 8 so as to protrude downward.

The introduction pipe 6 projects into a sump chamber 5 formed below a runner 8 by a container 4 made of a heat-resistant material such as cast iron or steel.

The water reservoir chamber 5 is communicated with the outside air through another introduction pipe 6 inserted from below.

The upper end opening of the lower introduction pipe 6 is positioned above the lower end opening of the upper introduction pipe 6, so that the upper and lower introduction pipes 6, 6 are staggered in the sump chamber 5.

Further, the lower introduction pipe 6 passes through and is supported by a refractory material 2 such as refractory cement or ceramics fixed to the lower end of the main body 1.

The lower end of the lower inlet pipe 6 is covered with a cap 16 of metal (which melts away at the temperature of molten pig iron).

The sump chamber 5 may contain additives (for example, tellurium, bismuth, boron, cerium, lead, antimony, magnesium, etc.) that promote whitening.

A method of using the apparatus of the present invention shown in the above embodiments will now be described.

That is, the device is immersed from the tip into molten pig iron.

As a result, the cap 16 melts away after passing the surface layer such as slag, and the lower end of the introduction pipe 6 opens into the molten pig iron.

This allows the molten pig iron to flow from the introduction pipe 6 to the sump chamber 5.
The liquid flows into the container 4, where it absorbs heat and its temperature drops (pre-cooled).

Furthermore, the molten pig iron fills the sump chamber 5 and flows into the inlet pipe 6 projecting into the sump chamber 5 from above.

Furthermore, the molten pig iron flows into the runner 8 and the partition 10,
11, the flow is disturbed, agitated, and cooled while reaching the collection chamber 13.

The molten pig iron is removed with heat by the cooling metal 15 in the sampling chamber 13 and solidifies while turning into white pig iron.

The device is pulled up after a predetermined period of time, and the solidified pig iron sample is taken out from the collection chamber 13 (half bodies 7a, 7
b) is used for spectroscopic analysis, etc.

FIG. 3 shows another device of the invention, which has the following features compared to that of FIG.

In other words, the water reservoir chamber 5 is arranged in multiple stages (the one shown is two stages).
1) which are inserted from the upper and lower sides in each water reservoir chamber 5 and whose openings are staggered.
A pair of inlet pipes 6, 6 are provided.

Therefore, the lowest water reservoir chamber 5 communicates with the outside air through the lower introduction pipe 6, and the uppermost water reservoir chamber 5 communicates with the runner 8 through the upper introduction pipe 6. .

Therefore, during use, molten pig iron reaches the runner 8 through a plurality of pool chambers 5.
The temperature at the inlet can be controlled to be lower than that in FIG.

The white pig iron sampling device of the present invention has the following effects in terms of the configuration and operation described above.

(1) The white pig iron sampling device of the present invention has the configuration described in the claims for utility model registration, and in particular, the runner 8
Since the molten pig iron has a pool chamber 5 below, the molten pig iron flows into the collection chamber 13 after being precooled in one or more stages of the pool chamber 5, and as a result, the temperature at the time of flowing into the runner 8 can be easily controlled ( For example, high-temperature pig iron can be rapidly cooled in the collection chamber 13 by cooling in the plurality of stages of sump chambers 5, and a sample that has been sufficiently whitened can be collected.

(2) The white pig iron sampling device of the present invention has the same configuration as above, and in particular, since the runner 8 has partitions 10 and 11, the molten pig iron is sufficiently stirred and flows into the sampling chamber 13, and as a result, the white pig iron is converted into white pig iron. is further promoted.
