<p>23 Wet chemical, microcomputer-controlled procedure for the rapid dissolution of metal followed by accurate determination of elements in the sample and, more specifically, suited to meet steel industry requirements for control of the level of acid-soluble aluminum in steel during the making of steel, is described. A sample of steel to be tested is normally placed in an electrolytic cell wherein a known portion of the sample is dissolved electrolytically in dilute cold acid. The aluminum content of the resulting solution is determined spectrophotometrically. The apparatus is compact and readily installed near the steelmaking operation.</p> |
