[0024] Example Melt Smelting Sampling-X-ray Fluorescence Spectrometry Analysis and Determination of Ferrovanadium Composition

[0025] (1) Sample preparation method

[0026] Take out the molten ferrovanadium sample from the smelting electric furnace, and quickly cast it into a sample block. It is required that the sample is uniform without delamination, the surface is smooth, and there is no crack damage. The sample is initially polished on the grinding wheel prototype, and then finely polished by the surface grinder. It is required that the polished surface should be smooth, with clear lines, no crossing, no flash, no pores, inclusions and cracks. The sample should not be overheated and cannot be stained. Calibration standard samples and analytical samples should be ground under the same conditions without overheating to prevent sample oxidation.

Abstract

The invention belongs to the technical field of the detection of vanadium iron, and particularly relates to a method for analyzing vanadium iron ingredients by a melt smelting sampling-X-ray fluorescence spectrum process. The method comprises the following steps of: (1) in a low-content calibration standard sample, mixing a vanadiumiron guide sample and pure iron powder, smelting under vacuum, casting for forming, measuring by using an X-ray fluorescence spectrograph, measuring the strength of a high-content calibration standard sample on the X-ray fluorescence spectrograph, crushing, analyzing a constant value by a wet process, and establishing a standard curve for each calibration standard sample, wherein the high-content calibration standard sample is a vanadium iron sample with different ingredient content gradients; and (2) taking a vanadium iron melt in a smelting electric furnace, casting to form blocks, polishing, measuring by using the X-ray fluorescence spectrograph, and calculating the content of each element in vanadium iron according to the standard curve drawn in the step (1). By the method, analytical information can be fed back within 10 minutes, so the method has the characteristics of high speed, high efficiency, low cost, safety and environment friendliness, and is suitable for quick and on-spot analysis of a ferroalloy smelting furnace.

Description

technical field [0001] The invention belongs to the technical field of vanadium-iron alloy detection, and in particular relates to a method for analyzing components of vanadium-iron alloys by means of melt smelting sampling-X-ray fluorescence spectrometry. Background technique [0002] With the development of production technology of vanadium ferroalloy, the control precision of the smelting process is getting higher and higher. The chemical analysis method that has been used for a long time has a long analysis period and single function, which can no longer meet the needs of production. [0003] X-ray fluorescence spectrometry is an important analytical instrument for quality control in modern industry. It has the characteristics of fast analysis speed, wide range of detection elements, and various types of analysis materials. It can greatly reduce the labor intensity of analysts and has been widely used in various industries. application. X-ray fluorescence spectrometry f...
