    • The invention concerns a process for handling metals, in particular steel, in a vacuum, in which molten metal is contained in a vessel (30) for in vacuo handling which is tightly sealed by a lid (20). To obtain a process and a device for handling metals, in particular steel, in a vacuum, which obviate the conventional drawbacks by simple means, which dispense with the need for free space in the ladle (46) and which do not prevent gas from escaping from the melt (41), the surface (42) of the molten metal is subjected to different partial vacuums during in vacuo handling.
    • 本发明涉及在真空中处理金属,特别是钢的方法,其中熔融金属包含在用于真空处理的容器(30)中,该容器由盖子(20)密封。 为了获得用于在真空中处理金属(特别是钢)的方法和装置,其通过简单的手段消除了常规缺点,这避免了在钢包(46)中需要自由空间并且不阻止气体逸出 在熔融物(41)中,熔融金属的表面(42)在真空处理期间经受不同的部分真空。

    • The invention concerns a method of decarburizing steel melts in a closed metallurgical vessel connected to a vacumm pump and into which oxygen can be supplied by means of a lance and combustible materials by means of a feed device. The method calls for the following steps: a) the melt is poured into the vessel, the pressure reduced continously to less than 100 mbar and oxygen blown in in order to burn off the carbon, the oxygen being blown in in predefined excess, in addition to the supplementary oxygen used during the decarburization phase; b) at the moment when the oxygen is in partial excess, metallic combustion material is supplied, distributed uniformly throughout the melt. The invention also concerns a device which includes sensors (21 and 29), located in the closable vessel, for the measurement of the melt temperature (T) and pressure (P), respectively, and which are connected via a measurement and control unit (22) to control elements (23, 25) for supplying oxygen (O2) and metallic combustion materials (A).
    • 本发明涉及一种用于钢的脱碳在一个封闭的冶金容器,它连接到一个真空系统和可燃物质通过喷枪氧,以及一个进给装置引入熔化。 这里,下面的步骤被执行:1)引入熔融的和连续减少低于100毫巴至脱碳用于进行碳烧掉补充氧气期间采用的压力的除被注入后,过量的氧的可预先确定的量; b)在部分Sauerstoffüberberschusses金属燃料的时间被添加均匀地分布。 此外,本发明涉及一种设备,其特征在于,有在所述可密封的容器的测量元件(21和29),用于通过测量和控制装置检测到所述熔融温度(T和压力P)提供(22),其具有控制部件(23,25) 用于供应氧气(O 2)和金属燃料(A)被连接。
