    The invention relates to ferrous metallurgy, in particular, to devices for introducing easily evaporating reagents into the liquid metal.
    A device is known for introducing reagents into a liquid metal, in particular for introducing magnesium carbon melt into an iron-carbonaceous melt, consisting of a working tank into which a suspension tube is inserted suspended on the loading pipe to the protective tank of the vessel with holes in its wall. the cavity of which communicates with the cavity of the loading pipe, and made of a metal armature located in the refractory lining, which also covers the loading pipe on the outer perimeter of the working pipe ij capacity
    However, a strong heating of the saipus pipe and flash-like reactions in the immersion bell during the immersion process lead to the formation of cracks and often to the destruction of the refractory material of the immersion bell or loading tube in the zone of their connection, so that the contents of the reaction chamber during the immersion process can suddenly and uncontrollably pour out into molten metal.
    The aim of the invention is to increase the durability of the device;
    The goal is achieved by the fact that the device for introducing the reagent, in particular, magnesium, into the molten metal, for example iron-carbon melt, to produce nodular cast iron, containing an operating vessel with a protective cap, into which the dip tube suspended on the loading tube is inserted the metal frame and the refractory lining, which encloses the metal frame and the outer perimeter of the loading ± pipe in the area entering the vessel, with holes in the stash of the bell and its cavity a loading tube with a cavity, is provided with a flange mounted on the end of the loading tube, and between the refractory lining on the one hand and the loading tube, and a protective flange Jug other hand expansion gap is formed.
    In the refractory material between the metal frame and the refractory lining temperature seams are made.
    Refractory lining reinforced with austenitic steel fibers.
    The drawing shows a device for the introduction of reagents, a general view.
    The device consists of a working capacity of 1, c. which is inserted into the immersion bell 2. The working tank 1, filled with molten metal 3, is closed with a protective cover 4. The protective cover 4 carries the loading tube 5, to the free end of which is suspended a submersible bell 2, made of metal fittings located in a fire lining, which also covers the outer perimeter of the loading pipe 5 in the area entering the working tank 1. The immersion bell 2 has a reaction chamber 6 with contact holes 7 for communication with the molten metal. To fasten the immersion bell 2 to the loading pipe 5, a flange 8 is installed at its end on the side of the bell, embedded in a refractory mass 9. a gap 11. A basket-shaped metal reinforcement 12 is connected to the flange 8, which, being inserted into the refractory mass 9, surrounds the reaction chamber b, Temperature joints 13 are also provided between the metal reinforcement 12 and the fire, and fibrous reinforcement 14, consisting of austenitic scraps of high-quality steel, is uniformly introduced into the refractory mass 9. The loading tube 5 is sealed with a stopper 15.
    The device works as follows
    J.
    Reagents, nagrimer magnesium, are introduced into the reaction chamber 6 through the loading tube 5. The reaction chamber is closed using a stop cap and, lowering the cover 4, the immersion bell 2 with the reaction chamber 6 is introduced into the working tank 1 filled with metal 3. The metal 3 through the contact holes 7 reacts with the reagent and melts it, the right degree Due to the presence of the flange 8 and the temperature gap 11, the possibility of cracking and the uncontrolled introduction of the reagent into the metal is eliminated
