摘要： The present invention relates to an apparatus for preparing binder-free hot briquettes for smelting purposes consisting of iron-containing pyrophorous finely divided solids. Before briquetting, the finely divided solids are blown-through by means of a rising oxidating heated gas flow and held in a fluidized bed. The gas flow is controlled in such a way that by oxidation of at least part of the metallic iron the temperature of the finely divided solids is increased to about 450.degree. to 65020 C. Subsequently, the solids are briquetted in hot condition. Characteristic for the invention is that there is added to the fluidized bed sensible heat from the outside until oxidation of part of the metallic iron starts, and that the fluidized bed is submitted to the effect of vibrations favoring the the conveying of the solids over the fluidized bed.

摘要： An improvement in a process for forming a refractory lining on the interior walls of the metallurgical vessel which interior walls are coaxial to the principal axis of the vessel wherein a refractory mass containing a binder is centrifugally slung onto the interior walls in a direction normal thereto while the vessel is at a standstill is disclosed. According to the invention, the refractory mass is initially shaped into balls prior to being centrifugally slung and the balls are centrifugally slung in rapid succession to form a mass jet. Also disclosed, is a device for so slinging a refractory mass on the walls of a vessel comprising a slinger head having a slinger wheel and a motor and at least one supply conduit for supplying refractory mass to be slung. The slinger wheel of the slinger head is disposed on one end of a shaft which shaft is extendable into a vessel, the slinger wheel being connected to an actuatable by a slinger motor. The slinger unit includes a slinger head, the shaft and the slinger motor as well as the supply conduit and is rotatable about the axis which extends in the direction of the entrance to the vessel.
