Problems solved by technology

One sample is taken for every additional 500kg, up to 7 samples. The disadvantage of such sampling is that the samples taken are not representative, because sometimes the composition of different samples in each barrel varies greatly, and if a large number of incoming materials, only take 7 causes many ingredients to go out of inspection

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.

Abstract

The invention discloses a multi-component rare earth raw material sampling method. The rare earth raw materials comprise lanthanum-cerium alloy, cell-grade mixed rare earth and a multi-component rare earth alloy composed of two or more rare earth elements. The rare earth raw materials are metals in as-cast state, have clean surfaces and no obvious oxide layers and form metal alloy ingots without obvious included slag. The multi-component rare earth raw material sampling method comprises determining sampling number according to a material detail form provided by a supplier and the number of one batch of fed materials, taking samples by a drill bit, weighing the samples according to the material detail form provided by the supplier, combining the samples to form an integrated sample, pre-treating the integrated sample and detecting ingredients of the multi-component rare earth alloy. The multi-component rare earth raw material sampling method has the advantages that the taken sample is representative, the detection result is real and reliable and production burdening is accurate.

Description

technical field [0001] The invention relates to a method for sampling multi-component rare earth raw materials, the rare earth raw materials include lanthanum-cerium alloys, battery grade mixed rare earths and multi-component rare earth alloys composed of two or more rare earth elements; the rare earth The raw material is cast metal, the surface is clean, there is no obvious oxide layer, and the metal alloy ingot has no obvious slag inclusion. The rare earth raw material is hydrogen storage alloy powder for nickel-hydrogen batteries. The hydrogen storage alloy is a material that can absorb and release hydrogen under certain conditions and has reversible hydrogen absorption and desorption properties. Background technique [0002] At present, the sampling method for multi-component rare earth raw materials is to take 4-7 samples for each incoming batch of rare earth raw materials, and when the weight of each batch is ≤500 Kg, take 4 samples. One sample is taken for every addi...
