Description

Technical Field

[0001] The invention relates to an ignition device and method outside a furnace, belonging to the technical field of alloy production equipment and methods. Background Art

[0002] The aluminothermic process is a metallothermic reduction method using aluminum as a reducing agent. When aluminum reacts with metal oxides, it generates sufficient heat to melt and separate the reduced metal and the resulting slag, yielding the metal or alloy. The aluminothermic process is primarily used to produce ferroalloys and master alloys containing high-melting-point metals and difficult-to-reduced elements.

[0003] Thermite reaction primarily involves igniting the reactants with an external heat source, triggering the reaction. Thermite reaction is characterized by high heat and rapid reaction speed. Improper operation can lead to serious production safety accidents. Therefore, the development of an automatic ignition device and method can prevent safety accidents such as fires and explosions caused by misoperation or equipment failure. Summary of the Invention
