Project Description

SALT BATH FURNACE

TMAX 850°C

Salt bath furnaces are characterized by rapid heat transfer and exceptional temperature uniformity. MSE produces salt bath furnaces for operating temperatures up to 850°C.

Salt bath furnaces are one of the oldest methods of use.

PRODUCT INFORMATION

Salt bath furnace provides fast and homogeneous heating, controlled cooling conditions during quenching, low surface oxidation and decarburization. When parts are immersed in the molten salt of the furnace, heat is transferred directly contact to the surface. Heat transfer into parts is very rapid faster than with radiation or convection methods. The working parts that inside of the salt can’t contact air. So, oxidation and decarburisation are prevented.

Additionally, by the uniform rate of heat transfer permits components having complex geometries and diverse cross-sections to be heat treated and quenched with minimal distortion. Salt bath furnace is ideal for case hardening of low carbon steels and the neutral hardening of higher carbon and alloy steels, including tool steels.

Generally capital of salt bath furnace cost is low. But safe disposal of the used salt is needed. This situation due to environmental, health and safety considerations can affect to operating cost.

APPLICATION NOTES

For the maximum life of the furnace and the longer use of the furnace equipment, we recommend that the heating rate of 10 °C/min should not exceeded. Flammable and explosive products must not be used in the furnace.

The chemical salt which is inside the furnace must not touch with water and with damp any pieces.

If the salt long-term as cold stays, it may get solid. In these cases, it is better to pre-heating without a sample.

SERIES

Salt bath furnaces are manufactured in wide a range of volumes and temperatures up to 850°C.
