Abstract

PURPOSE:To provide a sampler capable of effectively sampling a slag from an upper opening of a converter even when the surface of a molten metal moves up and down in the blowing during the making of a pipe. CONSTITUTION:A sampler 1 is equipped with a cylindrical shaped hollow pipe 2 which is attached to a tip portion 4a of an elongate rod shaped holder 4. A handle section for a worker is formed in the other tip portion 4b of the holder 4. The bottom end 2a of the hollow pipe 2 is opened for inputting or sampling a molten metal and the top portion thereof is closed by means of a top plate 2b, thereby preventing a molten metal splashes from going into the hollow pipe from the top portion. Further, at the upper portion of the hollow pipe 2, e.g. a side face adjacent to the top plate 2b, a hole 6 for discharging a gas is formed.

DISCLOSURE OF THE INVENTION The inventors of the present invention produced a cylindrical cylindrical sampler 100 ′ made of steel having a sample intake opening on the side surface of the same shape as the paper tube container 100,
We tried to collect the slag in the converter. for that reason,
In the converter 110 as shown in FIG. 2, the molten metal L in the converter is
After measuring the level, the opening 10 of the sampler 100 '
The sampler 100 ′ was inserted into the furnace through the insertion opening at the upper part of the converter 110 and the discharge port 112, aiming at 2 ′ near the converter tuyere 114 and at the surface layer of the molten metal.

As a cause for this, although the sampler opening 102 'is aimed so as to come to the surface of the molten metal by referring to the level of the molten metal measured before sampling, the surface of the molten metal L is as shown in FIG. During the drafting period,
It is considered that this is because the sampler opening 102 ′ actually reaches the white paste layer because it moves up and down violently. In other words, it has been found that it is difficult or practically impossible to sample only the surface part of the molten metal by the sampler in the converter smelting.
