Learn about the principles, applications, and features of salt bath furnaces for heat treatment of metals. Ajax Electric offers various types of salt bath furnaces for different industries and purposes. The salt-bath furnaces TS 20/15 - TSB 90/80 can be used for heat treatment of metals in neutral and active salt baths.
They are used for processes such as nitriding according to Tenifer up to 600 °C, carburization to 950 °C or bright annealing to 1000 °C. Upton Industries began as a manufacturer of molten salt bath equipment in 1937 with the advent of the submerged electrode design which has since become the industry standard for electric salt bath furnaces. The expertise gained from our original endeavor has since been expanded to more traditional lines of thermal processing equipment including box type, car bottom, liftoff and specialty.
Salt Bath Heat Treatment Working Principle Salt bath heat treatment is a process used to enhance the properties of metal components. It involves immersing the parts in a bath of molten salt at high temperatures. The salt acts as a medium for heat transfer, allowing for rapid and uniform heating of the parts.
Water bath heaters are typically suited for applications where the outlet process temperature is no greater than 189 °F. Two common subtypes of water bath heaters are salt bath heaters and direct. Operating temperatures for salt baths can be as low as 300ºF or as high as 3000ºF.
The salts can be directly heated using electric energy introduced with immersed electrodes, or indirectly heated in a metal pot with either gas or electric heat. Fluidtherm manufactures these new furnaces or rebuilds them, regardless of their original manufacturer. The salt bath furnaces and the hot water rinse tanks require gas piping for the burners.
The rinse tanks require water fill, drain, overflow and on occasion air agitation piping. What is a Salt Bath Furnace? A Salt Bath Furnace is a type of heat treatment equipment that uses molten salt as the heating medium instead of air or gas. The workpieces are immersed directly into a heated bath of molten salt, which transfers heat rapidly and uniformly.
The salt bath operates at temperatures typically ranging from 150°C to 1300°C, depending on the process requirements. These. The DM series Electrode Salt Bath Furnace are provided for temperature up to 1300ºC.
Crucible salt bath furnace is widely used in military industry, Aerospace industry, automobile industry, various metal parts Non. Superior Annealing Furnaces from Ajax Electric Co. Due to the exceptional temperature control necessary for annealing, salt baths are often used to heat and cool metal.
Salt baths offer the advantage of uniform temperature throughout the bath, faster heating, and highly regulated cooling for a more efficient process that reduces production time.
