Abstract

871,210. Refining iron. ARBED, ACIERIES REUNIES DE BURBACHEICH-DUDELANGE S.A. April 23, 1959 [April 29, 1958], No. 13827/59. Class 72 [Also in Group XL(b)] Foaming of the slag in a converter, surface blown with oxygen and suspended dephosphorizing agent, is counteracted in response to a decrease in the infra red radiation of the flame being detected. As shown, photocell 1 receives light from the flame of the converter along line 6 through one micron wavelength filter 2. The intensity of radiation is recorded at 5. When this intensity drops, the lance 7 is lowered to reduce foaming.
