Production Process
iron powder for welding materials
Chemical Equation: Fe3O4+4H2=3Fe+4H2O
Use reducing agent, such as coke, carbon, anthracite, Water gas, natural gas, Dissociated Ammonia or hydrogen to reduce the oxide of iron, for getting reduced iron powder.
(Iron Concentrate or rolling steel scale) → drying → Magnetic separation → shattered → screen → tinning → into once reduced furnace → get sponge iron
