Sample for low-carbon ferrochrome chemical analysis and sample preparation method

The invention relates to the field of iron and steel smelting, in particular to a sample for low-carbon ferrochrome chemical analysis and a sample preparation method. The method comprises the following steps: crushing a batch of low-carbon ferrochrome samples step by step according to a first size fraction, a second size fraction, a third size fraction and a fourth size fraction to enable the particle sizes of the low-carbon ferrochrome samples to be gradually reduced; and screening the low-carbon ferrochrome samples subjected to the fourth size fraction crushing, and taking a sample with theparticle size of less than or equal to 1.6 mm. According to the method provided by the invention, various problems caused by sample preparation through a drilling method in the prior art can be solved, the sample preparation difficulty of the sample for low-carbon ferrochrome chemical analysis can be greatly reduced, and the sample preparation time is saved. According to the sample preparation method of the sample for low
