[0002] The production of vanadium aluminum, molybdenum aluminum, molybdenum vanadium aluminum and other intermediate alloys required for aerospace titanium alloys all adopts the aluminothermic method, which is a metal thermal reduction method using aluminum as a reducing agent. When aluminum reacts with metal oxides, it generates enough heat to melt and separate the molten metal and slag to obtain metal or alloy. The aluminothermic method is mainly used to produce ferroalloys and intermediate alloys containing high melting point metals and difficult-to-reduce elements.

[0003] Thermite reaction is generally initiated by igniting the reaction materials with an external heat source. Thermite reaction is characterized by high reaction heat and fast reaction speed. If the charge is not compacted, the gaps between the charge particles are large and there is a large amount of air, the thermite reaction will be violent, with severe splashing during the reaction and a large number of honeycomb pore defects inside the alloy after cooling.

[0004] By consulting the data and literature, it is known that there is no equipment and method for automatic compaction of furnace charge in the current aluminothermic process and production practice. Therefore, the present invention is proposed to solve the actual demand of the aluminothermic process for equipment and method for automatic compaction of furnace charge. Summary of the invention
