Embodiment 1
[0016] Example 1: A kind of sampling method of lanthanum cerium rare earth metal raw material, such as figure 1 As shown; a batch of lanthanum-cerium rare earth metal raw materials weighs 10 tons, and there are a total of 10 small batches, that is, each small batch is 1 ton, and each 1 ton is packed in 4 barrels. The supplier's material list is as follows: 10 sets of detection data. Take 3 barrels per 1 ton, that is, each small batch, and take one sample per barrel. For each small batch of three alloy ingot samples, use a 7mm drill to drill the samples, and discard the 0.5-1.0mm from the surface. Drilling cuttings, and then put the drilled samples into the sampling bag immediately; then weigh the samples according to the ratio of 1:1:1 to form a comprehensive sample, a total of 10 comprehensive samples. After comprehensive sample pretreatment, it was detected by ICP-AES spectrometer.
[0017] In order to prove the practicability and reliability of the method, the conventio...
Embodiment 2
[0020] Example 2: A kind of sampling method of lanthanum cerium rare earth metal raw material, such as figure 1 As shown; if one incoming material is 5 tons, and 5 tons of raw materials are a batch, at least 4 barrels are used for each 1 ton, and only one set of test data is displayed on the material list of the supplier; 6 barrels of incoming materials are randomly selected, Take one sample per barrel, drill the sample with an 8mm drill bit for 6 alloy ingot samples, discard the drill cuttings 0.5-1.0mm from the surface, and then immediately put the drilled sample into the sampling bag; every two samples Weigh the samples according to the ratio of 1:1 to form a comprehensive sample, a total of 3 comprehensive samples. After comprehensive sample pretreatment, it was detected by ICP-AES spectrometer.
Embodiment 3
[0021] Embodiment 3: A kind of sampling method of lanthanum cerium rare earth metal raw material, such as figure 1 As shown; if one incoming material is 12 tons, and the 12 tons of raw materials are a batch, at least 4 barrels are used for each 1 ton, and only one set of test data is displayed on the material list of the supplier; then 8 barrels of incoming materials are randomly selected, Take one sample per barrel, drill samples with a 9mm drill bit for 8 alloy ingot samples, discard the drill cuttings 0.5-1.0mm from the surface, and then immediately put the drilled samples into the sampling bag; every two samples Weigh the samples according to the ratio of 1:1 to form a comprehensive sample, a total of 6 comprehensive samples. After comprehensive sample pretreatment, it was detected by ICP-AES spectrometer.
