摘要： Gas purging element (10) comprises (a) a refractory ceramic body having a first end and a second end. The second end is in the installed state of the gas purging element in contact with a molten metal. The first end is externally covered by a metal sheath (12) having an opening (16) which is followed by a gas connection pipe (20). The gas purging element, the body and the gas connection pipe are designed such that a treatment gas flows through the body, which is supplied via the gas connection pipe and emerges from the body at the second end. Gas purging element (10) comprises (a) a refractory ceramic body having a first end and a second end. The second end is in the installed state of the gas purging element in contact with a molten metal. The first end is externally covered by a metal sheath (12) having an opening (16) which is followed by a gas connection pipe (20). The gas purging element, the body and the gas connection pipe are designed such that a treatment gas flows through the body, which is supplied via the gas connection pipe and emerges from the body at the second end. The gas connection pipe is connected to the metal sheath and is formed as a plug or socket of a plug connection for connecting to a corresponding socket, or a corresponding connector of a gas supply line (30). An independent claim is also included for a gas supply line for a gas purging element, comprising a first end and a second end for connection to the gas connection socket of the gas purging element, where the second end corresponds to the gas connection pipe as a plug or socket of the plug-in connection between the gas connection pipe.

摘要： A method is described for preheating annealing material (4, 5) in a hood-type annealing system, comprising annealing bases (1, 2) which accommodate the annealing material (4, 5) under a protective cover (7) in a protective gas atmosphere, with the annealing material (4) to be subjected to a heat treatment in a protective cover (7) being preheated with the help of a gaseous heat carrier which flows in a cycle around the protective covers (7) on the outside and absorbs heat from annealing material (5) which is already heat-treated in a protective cover (7) and emits it to the annealing material (4) to be preheated in the other protective cover (7). In order to achieve advantageous utilization of the thermal energy it is proposed that for the heat treatment of the annealing material (4, 5, 6) at least one further annealing base (3) is used which comprises a protective hood (7) which is heatable from the outside by a burner (15), and that the hot exhaust gases from the heating of the protective hood (7) are admixed into the heated heat carrier for preheating the annealing material (4).

摘要： A modular lateral transfer system for use in a horizontally oriented processing chamber is provided. Each module has the ability to deliver process gas in addition to moving the reactant material through the horizontally oriented processing chamber. The modular design enables the operator to remove and replace a module of the system, thereby substantially minimizing the downtime of the chamber required during servicing.

摘要： A method for producing ferro-chrome alloys comprising a stoichiometric charge and stoichiometric slag calculation step, a step of making the plant and the crucible furnace operate at normal regime, steps of casting the metal and the slag, a step of collecting the molten metal in suitable modular molds made from spheroidal graphite cast iron, a step of removing the ingots contained in the molds with suitable pincer means, a step of collecting the slag in suitable nonrefractory bells or ladles, characterized in that the metal-slag separation takes place directly inside the furnace and in that said castings of metal and slag take place in successive steps so as to allow the drawing off of the liquids in the amounts formed between one casting and the next.
