specific Embodiment approach 1

[0007] Specific implementation mode one: combine figure 1 and figure 2 Describe this embodiment, the mold of this embodiment includes two mold bodies 1 with the same shape and geometric dimensions, the two mold bodies 1 form a cylinder, and there are connected gates 2 and horn channels 3 in the mold from top to bottom. , the central channel 4 and the sample bottom cavity 5, the outer diameter D of the cylindrical mold body 1 is 104 mm, the inner diameter d of the sample bottom cavity 5 is 42 mm, and the height of the bottom cavity 5 is 5 mm.

[0008] The material of the mold body of the present invention is processed by low-cost carbon steel material, which is suitable for large-scale sampling on site. Copper material can also be used, and the whitening effect is better, but the cost is high and it is not convenient for on-site storage.

[0009] The diameter of the mold body can be increased to increase the heat capacity of the mold body and speed up the cooling of the sampl...

specific Embodiment approach 2

[0011] Specific implementation mode two: combination figure 1 Describe the present embodiment, the described mold of the present embodiment also comprises heat dissipation plate 6, and two die bodies are arranged on the top of heat dissipation plate 6, and heat dissipation plate 6 is a copper plate, and the thickness of heat dissipation plate 6 is 10mm, and this structure enlarges mold body heat capacity while accelerating sample cooling. Other implementation manners are the same as the specific implementation manner 1.

Abstract

The invention discloses a taken-sample chilling mold for measuring a pig iron sample, relating to a taken-sample chilling mold and designed for solving the problem that the chilling degree of a pig iron sample is low at present. The mold comprises two molds which are completely the same in shape and geometric dimension; the two molds form a cylinder; sprues, horn channel, central channels and a sample bottom chamber which are communicated from top to bottom are formed inside the mold; the outer diameter of the cylinder is 104mm; the inner diameter of the sampling bottom chamber is 42mm; and the height of the bottom chamber is 5mm.The mold is used for measuring a pig iron sample.

Description

technical field [0001] The invention relates to a whitening mold for sampling and preparation. Background technique [0002] At present, in iron and steel enterprises at home and abroad, there are various analytical methods for pig iron, mainly including chemical methods and instrumental methods. In terms of accuracy, the chemical method has advantages, and it has been established and has corresponding analysis standards, but it has the disadvantages of slow analysis rhythm and great influence of human factors, which is not conducive to rapid inspection and timely guidance of production. Instrumental methods mainly include fluorescence spectroscopy and direct reading spectroscopy, which are often used in qualitative, semi-quantitative, and quantitative analysis. This method is simple, fast, and accurate. In general, it can be used for the determination of components with a content of less than 1%, and it is widely used in the iron and steel industry. However, there are cer...
