1. A method of aluminothermic welding by pouring intermediate metal, in which steel, obtained after burning of thermite mixture is poured into fire-resistant casting mould, and into which are included the ends of rails to be welded, while a part of steel poured off from a reaction crucible and which forms a welded joint in the zone of the rail head is brought into contact with additional alloying admixtures, wherein said additional alloying admixtures are introduced into after said aluminothermic reaction is over and separation the is separated from slag during steel drain before pouring the steel into a cavity, formed by said casting mould and with closed overflow in said casting mould 2. A method of Claim 1, wherein said alloying admixtures are introduced before pouring the steel into the cavity, formed by said casting mould, using automatic crucible separating layer. 3. A method of Claim 2, wherein said alloying admixtures are arranged in the cavity beneath the crucible-separating layer. 4. A method of Claim 2, wherein said alloying admixtures are added into a moulding mixture when forming the body of said crucible separating layer. 5. A method of the preceding Claims, wherein said alloying admixtures represent powder or granulate. 6. A method of Claims 1-3, wherein said alloying admixtures are used in a solid compact form. |
