<p>1536824 Converters CREUSOT-LOIRE ENTREPRISES and CLESID SA 10 June 1977 [16 June 1976] 24447/77 Heading F4B A horizontally mounted cylindrical metallurgical converter has a circumferential wide and elongated opening divided into two parts 10a and 10b. The converter is mounted so that it can turn about the horizontal axis 28, and has a "normal" position for simultaneous heating, melting and refining which is with the 10a part of the opening upright. In this position opening 10a can be occupied by a vertically movable refractory arch 11 containing orifices 12 for electrodes 13 and the arch may have a further orifice for admitting solid matter. The 10b part of the opening in the "normal" position lies in front of a first device 14 for collection of gases. The converter includes two rows of blast pipes 15, a tap hole 16 and a second device 17 for collection of gases. When heating of the furnace is required without blasting, the furnace is rocked anticlockwise 45 degrees so that blast pipes 15 are above the melt and opening 10a is opposite the second gas collector device 17. For tapping the arch 11 is withdrawn and the converter is turned further anti-clockwise so that metal can pass through the taphole 16 into a ladle.</p> |
