A steam atmosphere blackening furnace featuring both continuous and batch types. It forms a magnetite (Fe3O4) film on the surface of steel.
We handle a "blackening furnace (continuous/batch type)" that generates an oxide film using steam for rust prevention and hardness enhancement of iron-based metal parts. The continuous type allows for easy maintenance due to its segmented structure. The batch type, on the other hand, is equipped with a fan inside the furnace to circulate the steam atmosphere, enabling uniform treatment of magnetite (Fe3O4). 【Standard Specifications】 ■ Operating Temperature: 500–700℃ ■ Atmosphere: Steam atmosphere ■ Type: Continuous / Batch *For more details, please download the PDF or feel free to contact us.
