上充分に信頼される試料となる。[Detailed Description of the Invention] The present invention is an instrument for collecting a disk-shaped molten steel sample during the steelmaking process. Since the purpose of the molten steel sample is to analyze and measure its composition, it must be a reliable sample that can sufficiently represent the composition of the molten steel. For this purpose, the first requirement is that the sample be completely dense and have no internal cavities (cavities). The one that has been used in recent years is a two-part press mold 1, as shown in Figure 2.
Since the gas vent is pasted with only a few small holes at the rear end, the sample collected has a cavity inside due to insufficient gas venting, and the sample is not a dense complete sample. Not. Therefore, due to the characteristics of X-ray emission analysis, large errors and variations occur in analytical measurement values, making the sample unreliable. The sample of the present invention allows sufficient degassing and does not create cavities in the molten steel that is sucked in, making it a highly reliable sample for analysis.

ある。 The present invention will be explained in detail with reference to the drawings. As shown in Fig.
The divided wide metal ring 1 is sandwiched between metal disks 2 from left and right, fastened with heat-resistant tape 3, and a quartz tube 4 is fixed over the small hole provided at one end of the ring 1. When sucking molten steel, the ring 1 is inserted and fixed inside the ring 1 through the V-shaped cut groove provided on the outer periphery of the ring 1, the alignment with the left and right discs 2, and the gap between the inner gas and the molten steel. Since the air is evenly and sufficiently removed in the outward direction of the circumference, there are no cavities in the sample of molten steel that is sucked in, resulting in a completely dense sample that can be collected for analysis and measurement. . Furthermore, after the molten steel sample has cooled and solidified, when taking out the sample from the mold, the conventional mold is a two-part press mold, so casting burrs etc. get in the way, making it difficult to take it out. Since the ring 1 is divided into two parts and the disk 2 is also divided into two parts, making a total of four parts, they can be easily disassembled, so that the internal sample can be easily taken out.
