Times

Physical properties


Ferrochrome shall be in blocks, each weight shall not be more than 15kg, the size of less than 20×20mm ferrochrome block weight shall not exceed 5% of the total weight of ferrochrome. If the demander has special requirements on the grain size, the two parties shall negotiate separately.


There should be no nonmetallic inclusions visible to the naked eye inside and on the surface of high carbon ferrochrome powder, but it is allowed to exist in a small amount when the coating on the ingot surface is not clean.


Sampling method: bulk verification sampling: when the batch is less than 10 tons, no less than 10 samples should be randomly taken from different parts; If the batch is more than 10 tons and less than 30 tons, no less than 20 samples should be randomly taken from different parts; When the batch is more than 30 tons, no less than 30 samples should be randomly taken from different parts. The weight of each sample shall be approximately the same and its lumpiness shall not be less than 20*20mm. The total amount of sampling shall not be less than 0.03% of the batch. All samples should be broken to less than 10mm, and then reduced to 1-2kg by quartering method. After blending, the samples should be divided into two equal parts, one for analysis and one for retention.


Package verification sampling: no less than 10% packages should be randomly selected for each batch. A small sample of approximately equal weight shall be randomly selected in each piece, with the lumpiness not less than 20*20mm, and not less than 8 small samples, up to 30 small samples. All the samples should be broken to less than 10mm and reduced to 1-2kg by the quartering method. After blending, the samples should be divided into two equal parts, one for analysis and the other for retention.
