Method for detecting content of elements in alloy raw material

Abstract

The invention belongs to the field of alloy raw material detection, and particularly relates to a method for detecting the content of elements in an alloy raw material. The method comprises the stepsthat S1, alloy raw materials needing to be detected are randomly sampled, and selected samples are put into a small smelting furnace to be smelted into alloy smelting liquid; and S2, the molten alloysmelting liquid is injected into a degassing tank to be mixed with gas, then the mixed gas is poured into a mold to be prepared into a sample blank, element content analysis is conducted on the sampleblank through a spectrum method, detection data are obtained, and finally a final result is obtained by comprehensively comparing the detection data. The alloy smelting liquid is injected into the degassing tank before being prepared into a sample blank, a stirring rod and a stirring plate are arranged in the degassing tank, and the stirring plate and the stirring rod act on the alloy smelting liquid, so that the alloy smelting liquid is violently stirred, mixed gas is separated out, and the accuracy of a detection result of the element content in a final alloy raw material is guaranteed.

Description

technical field [0001] The invention belongs to the field of alloy raw material detection, and specifically relates to a method for detecting element content in alloy raw materials. Background technique [0002] Alloy raw materials are substances with metallic properties synthesized by two or more metals and non-metals. They are one of the important raw materials for the production of metallurgical industries, and generally have a large block shape. Since iron and steel products are produced continuously, there is a large demand for alloy raw materials, and their unit prices are generally high, so alloy raw materials account for a large proportion of the procurement funds of the iron and steel industry. It can be seen that the incoming inspection of alloy raw materials is extremely critical. A common detection method is to take several samples from the alloy raw material to be tested, then melt the samples into an alloy melting liquid and use a mold to make a sample embryo,...

Problems solved by technology

[0005] In order to make up for the deficiencies of the existing technology, the existing method for detecting the element content in the alloy raw material does not completely remove the mixed gas in the alloy melting liquid after melting the total raw material sample, so that the produced sample embryo has too many pores and affects the quality of the alloy. The accuracy of the final element content detection results in the final alloy raw material, a method for detecting the element content in the alloy raw material proposed by the present invention
