Abstract

The invention discloses a nickel-iron spectrum standard sample and a preparation method thereof. The nickel-iron spectrum standard sample is characterized by comprising the following chemical elements by weight: 14.9-50.0% of Ni, 0.03-2.50% of C, 0.2-4.5% of Si, 0.004-0.040% of P, 0.002-0.300% of S, 0.4-2.0% of Co, 0.01-0.25% of Cu, 0.1-2.0% of Cr and 40-80% of Fe. The method utilizes processes including intermediate-frequency furnace smelting, rain drench type pouring, water cooling copper mould casting, tundish bottom pouring and the like, so that uniform component tissue of the spectrum standard sample is ensured.

Description

technical field [0001] The invention relates to a nickel-iron standard sample and a preparation method thereof, belonging to the field of metallurgical analysis. Background technique [0002] At present, ferronickel is an important raw material for smelting stainless steel, nickel-based alloys and other products. In order to control the quality of ferronickel products, production and use enterprises must have corresponding standard samples to evaluate and verify the quality of analysis, as well as calibration and drawing work curve. At present, there are no nickel-iron spectral standard samples at home and abroad to draw and calibrate the working curve of the instrument, which brings a lot of inconvenience to the spectral measurement of nickel-iron. In view of this, a special process was designed to develop a set of nickel-iron standard samples for spectrometer calibration and working curve drawing. Contents of the invention [0003] The object of the present invention i...
