  • Monitoring equipment which swivels into and out of a traveling line
    Patent number: 4477722
    Abstract: In monitoring rod or wire rolling mills it is useful to determine whether the rolling and cooling trains are free of obstacles. To that end a light source and an optoelectric sensor are swivelled into the traveling line of the goods to be rolled and after measurement they are swivelled out of the traveling line. The measured data are supplied to a control unit to which also detectors (30, 31) for the traveling goods arranged in front of the supply end and/or behind the discharge end of the rolling train are connected.

  • Process for piloting or controlling a steel refining process
    Patent number: 4147532
    Abstract: In a steel refining process control over the composition of the product is maintained in part by supplying blowing oxygen to the molten material in an amount predetermined for achieving FeO content which is required for slagging the manganese and phosphorus. Lime, if required, is added in accordance with the FeO content and the silicon content to give saturation in lime and in the quasi-ternary system CaO--FeO--SiO.sub.2 at the final temperature of the metal.
