“…Major elements in Saudi ores were determined effectively by instrumental neutron activation techniques as described in two recent papers (386,387), while the iron content of magnetite ores was determined by y-ray scattering after appropriate corrections were made to accommodate variations in sample density (360). A thermal neutron irradiation technique has been developed and applied to the simultaneous determination of Fe and A1 in iron ore fines on a moving rubber conveyoir belt ( I 71), while an americium-241 y-ray source has also been used for monitoring the iron concentration in ore concentrates on moving belts (397).…”

This review is produced from a search of the literature as performed with the DIALOG capabilities of Chemical Abstracts Service. The material covered in this particular review is a continuation of past reviews by the same authors and covers the period from September 1980 to October 1982 It is obvious that the level of activity in the publication of research results by analytical chemists and spectrographers in the steel industry is significantly reduced and directly reflects the malais that affects our industry. Without being overly critical, we will have approximately 300 less literature citations in this review as compared to the last one (448). ALUMINUMTotal trace aluminum was determined spectro hotometpriate dissolution steps as an Eriochrome Cyanine R complex (98), by using Chromazol KS as a color-forming agent (269), as a colored complex with salicylidene-o-aminophenol-4sulfonic acid (523), and with l-pheny1-2,3-dimethylpyrazolone-5-azopyrogallol (13).Low levels of A1 have been determined in high-and lowalloy steels and ferrovanadium by atomic absorption after separation from the matrix by electrolysis (94). The determination of acid soluble aluminum by AA continues to be a very popular method in the steel industry by virtue of its rapidity (51,76,511). Low concentrations were also determined in silicon steels by using electrothermal atomization (245). Direct injection of a dissolved steel sample into an AI-H flame has been reported (282).AA has not supplanted emission spectrochemical methods for this determination as they continue to be used for both soluble and insoluble aluminum determinations in steel (135,304). One method involves the premelting of a selected zone on a sample surface in an inert atmosphere so as to concentrate the insoluble aluminum inclusions in the surface of the remelted zone upon which the surface is mechanically removed and subsequently analyzed spectrally for the soluble portion (76). A design for an instrument has been claimed that eliminates anomalous emission spectrometric signals from aluminum inclusions, thus permitting the determination of acid-soluble A1 with high precision (452). rically in some unalloyed and low-alloyed steels a P ter appro-Various other procedures have been applied in a general way for the analysis of steel and related materials and include the use of lasers for localized sampling prior to spectral excitation (208,311), Grimm glow-discharge source excitation (466), ICP emission spectrometry (15,101), an acid dissolution, ignition, and NaF fluxing prior to dc arc excitation for stainless-steel analysis (299), and the use of dc plasma techniques for iron ores, sinters, and dust analysis (369).The accuracy of XRF spectrometry for determining A1 in low-alloy and stainless steels (at <0.1%) has reportedly been improved by adding granular FeZr to the molten metal during sampling (184). Conversely, a rapid and high percision XRF method for the determination of the A1203 content of steels has been described (317). Procedures for the routine XRF analysis of iron...

Neutron activation analysis / Minor elements / Metallurgical samples / Iron and steel industrySummary. In this work instrumental neutron activation analysis (INAA) was applied to investigate a total of 30 samples of metallurgical raw materials (sinter, pellets, coke) and related finished products (pig iron, slag, blast-furnace flue dust) sampled from the same blast furnace discharge in the ironmaking process in the Integrated Iron and Steel Works of Galati (Romania). The transfer efficiencies of minor elements As, Cu, K, Na, V and W from raw materials -iron-bearing components (sinter, pellets) and coke -to pig iron and their losses in slag and flue dust have been determined and a discussion of the behaviour of each element during the blast furnace process was done.
