Abstract

The invention provides a method for determining components of scrap steel and processing equipment for detecting scrap steel component sample. The method for determining the components of the scrap steel comprises the steps of A, sampling an iron-containing material containing machining scrap iron and crushed steel slag, and crushing by using a crusher; B, splitting the iron-containing material by using a riffle after crushing; C, under the sample condition, melting the divided iron-containing material obtained in the step B until slag and iron are completely separated, and naturally cooling to room temperature to obtain a slag sample and a steel ingot; and D, analyzing the contents of C, P, S, As, Si, Mn, Cr, Cu and TFe by adopting a spark discharge direct-reading spectrometer. The invention further provides equipment for measuring the components of the scrap steel. The inspection quality can be ensured, and the working efficiency is improved.

Description

Technical field [0001] The present invention relates to the field of metallurgical, and more particularly to the composition analysis of metallurgical materials, particularly a method of determining a scrap component and a processing apparatus detected by waste steel ingredient samples. Background technique [0002] At present, the amount of steel refining steel stove (scrap steel) made from iron-based materials such as iron, steel plant, the original steel, and the original refining steel, and the scrap steel (scrap steel) are artificial chemical analysis. Analysis test, due to the different resources of this type of ferritic (scrap), the stack ratio is uneven, the material is irregular, the composition difference is high, resulting in non-representative, difficulty, and detected test data. Differences are large, and they cannot guide smelting. [0003] In summary, there is a problem in the prior art: machine processing iron shrub (cut), broken steel sheaves such as iron-based m...
