Heat Treatment by Salt Bath Furnace

Salt Bath Furnace is suitable for High Speed Steel products which are thick components.
The Salt Bath Furnace is origin of the Heat Treatment and creates a high quality Heat Treatment.

The Features of Salt Bath Furnace

  1. Non-erosion. (surface protection)
  2. It performs as an extremely evenness heating (excellent temperature penetration) and also, possible to heat a specific area independently (specific area heating possible) because Salt is flowed by Electromagnetic Stirrer to immersed products.
  3. It has enough heat content and heat conductivity for production (allowing for rapid heating and cooling)
  4. It reduces the curve produced by the weight of the products while it is being heated without coming up to the surface with giving specific gravity of 2~3 ascending force. (Reduces the deformation)
    As listed above, the Salt Bath Furnace has absolute advantage to perform ideal Heat Treatment compare to the Vacuum furnace. From single product (one product) is available.

Delivery shortened by Full Automatic Atmosphere Tempering Furnace.

  1. It is a fully automatic three-room structure; it has a Conveyance Table + Cooling Room, Heating Room, and Cooling Room + Extracting Table.
  2. Set the product into the basket, and push the start button, then temper twice repeatedly. It can place up to 3 baskets, and the tempered-products are sent to Extracting Table automatically the next morning, so it is greatly reduces the tempering time.
