    摘要： The invention relates to a process for producing steel of low phosphorus content from hot metal of usual phosphorus content, in which the hot metal is simultaneously decarburized and dephosphorized in a single process step in a metallurgical vessel, in particular in a converter. The refining gas consisting predominantly or completely of technically pure oxygen is top-blown into the melt, particularly from below. The vessel is charged with hot metal containing manganese in an amount of less than 0.2% by weight. Lime is then added and refining is carried out down to a final phosphorus content of 0.005% by weight or less in the steel at the end of blowing, without a change of slag.

    摘要： A process for continuous casting of a metal comprises continuously withdrawing a strand of the metal from a mold along a strand withdrawal direction, measuring the expansion of an inside wall of the mold along the strand withdrawal direction to obtain a component of inside wall expansion in the strand withdrawal direction due to mechanical forces exerted on the inside wall, and controlling the speed of withdrawal based on the component of inside wall expansion in the strand withdrawal direction due to mechanical forces. If the component of inside wall expansion of in the strand withdrawal direction due to mechanical forces exceeds certain limit values, the withdrawal step is slowed or interrupted, thereby eliminating break-outs due to cobbles. In an embodiment of the invention, expansion measurements are also taken along a direction transverse to the withdrawal direction, enabling the elimination of the component of expansion in the withdrawal direction due to heat.

    摘要翻译： 一种连续铸造金属的方法包括：沿钢丝绳退出方向从模具连续取出金属股，测量模具内壁沿钢丝绳退出方向的膨胀，从而获得内壁膨胀成分 由于施加在内壁上的机械力引起的股线退出方向，并且由于机械力而基于股线退出方向上的内壁膨胀部分来控制退出速度。 如果由于机械力引起的股线退出方向的内壁膨胀部分超过某一极限值，则退出步骤变慢或中断，从而消除由于鹅卵石而导致的断裂。 在本发明的一个实施例中，也沿横向于抽出方向的方向进行膨胀测量，从而能够消除由于热量引起的抽出方向的膨胀分量。

    摘要： The present invention relates to a process and 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. During said process 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 650.degree. 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 fluidization bed is submitted to the effect of vibrations favoring 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.
