Abstract: In an X-ray tube rotary anode having a supporting body (1) of molybedum alloy, a target (2) of tungsten alloy, and a rough tungsten layer, applied by flame spraying to the whole surface of the anode except the focal path (4), for improving heat radiation, the rought tungsten layer does not adhere well to the tungsten alloy target, and particles of the rough tungsten layer may become detached in use, degrading the performance of the X-ray tube. To alleviate this problem, the whole surface of the anode, except the focal path (4), is blasted with steel grit, steel grit particles embedded in the anode are removed with acid, and the whole surface of the anode, except the target (2), is coated with a rough tungsten layer (3) by plasma spraying.

Abstract: Particularly in small AOD converters (1), it is almost indispensable to preheat their brick lining almost up to the bath temperature of the molten steel, before they are filled with melt. Otherwise, the temperature losses are excessive. Appropriate temperatures can be reached only by means of fuel/oxygen burners. For this purpose, the burner must be positioned above or in the converter opening. Because of the high exit gas temperatures, water-cooled burners are used in most cases. After heating, the burner is swivelled away from the converter opening. The burner represents additional expense. To avoid this, at least one of the AOD nozzles (2) located above the converter bottom is used during heating-up for forming the fuel/oxygen flame (14). <IMAGE>
