In industry, ferrotitanium, ferromolybdenum, ferroniobium, ferroboron, ferrovanadium, ferrotungsten, metallic chromium, metallic manganese and master alloys such as nickel base, titanium base and aluminum base are usually produced by aluminothermic method.
A metal thermal reduction method using aluminum powder as reducing agent. When aluminum powder reacts with metal oxide, it generates enough heat to melt and separate the reduced metal from the formed slag to obtain metal or alloy. Widely used in the industrial production of pure metals (such as manganese, chromium, vanadium, etc.). ), carbon-free or low-carbon ferroalloy and metal welding.
Basic introduction Chinese name: aluminothermic method mbth: aluminothermic method uses: advantages of metal melting and welding: simple equipment, many products, short production cycle, potential safety hazards: high-heat reaction is prone to fire and explosion principle: brief introduction, advantages, brief history and principle of reducing the loss of low-oxide in slag by metal thermal reduction with aluminum powder as reducing agent, methods of increasing reaction heat, production technology, raw material preparation, batching, smelting, finishing and aluminothermic reduction to produce ferroniobium. When aluminum reacts with metal oxide, it generates enough heat to melt and separate the reduced metal and the formed slag to obtain metal or alloy. Widely used in the production of industrial pure metals (such as manganese, chromium, vanadium and so on). ), carbon-free or low-carbon ferroalloy and metal welding. Both aluminothermic method and silicothermic method with ferrosilicon as reducing agent are methods of producing ferroalloy by autothermal reaction, which are called metal thermal method, also called out-of-furnace method. They use aluminum particles, ferrosilicon powder or aluminum-magnesium alloy powder as reducing agents. The aluminothermic process is mainly used to produce ferroalloys, master alloys, refractory metals and refractory elements containing chromium and manganese. This product is characterized by extremely low carbon content (usually
