Batch steam treatment furnace

The Batch Steam Treatment Furnace is a closed-chamber, intermittent operation furnace designed to subject ferrous components (typically sintered metal parts) to superheated steam at elevated temperatures. The purpose is to form a magnetite (Fe₃O₄) oxide layer on the surface, enhancing corrosion resistance, wear resistance, and oil retention.

Unlike conveyor-type furnaces, batch furnaces treat components in discrete loads, making them ideal for flexible processing of different parts or small to medium production volumes.

🔧 Key Components and Features:

  • Steam treatment body with SUS321 material.
  • The insulation material is high-quality aluminum silicate cotton.
  • Electric heating is a strip or wire-shaped alloy that is convenient for maintenance.
  • The hot air circulation system ensures uniform temperature distribution inside the chamber.
  • Equipped with an over-temperature alarm system. When the furnace temperature exceeds the set range, it will emit an audible and visual alarm signal and cut off the heating power supply.
  • Because the furnace temperature is uniform, there is a certain pressure of steam inside the furnace, and the oxide film thickness of the product is 5-8mm, with good density and uniform hardness.
  • The atmosphere is H2O steam.
  • Nitrogen application for purging.
  • The steam flow is controlled by PLC program, and the data is displayed on the touch screen for easy control.
