Salt bath furnaces are used for:
Show Hint
- Melting metals
- Heat treating small parts
- Generating steam
- Incinerating waste
The Correct Option is B
Solution and Explanation
Step 1: Salt bath furnaces are specialized heating devices used primarily for the heat treatment of small metal components. The parts are immersed in a molten salt medium that provides uniform and controlled heating.
Step 2: This method is highly effective for applications such as hardening, tempering, annealing, and carburizing because it ensures excellent temperature uniformity and rapid heat transfer.
Step 3: The use of salt also prevents oxidation and scaling, preserving the surface finish of the components during treatment.
Why the other options are incorrect:
- (A) Melting metals typically requires crucible or induction furnaces.
- (C) Steam generation is done in boilers, not salt bath furnaces.
- (D) Incineration of waste is handled by incinerators, not designed for precision heating of parts.
