2 PagesHeater Failure Peppers Salt Bath Performance - Solved With Watlow Tubular Heaters Problem: Salt bath furnaces treat metals 300-750°F(150-400°C) to achieve improved uniform hardness, less distortion, and reduced cleaning time. Types of applications where these qualities are designed are: Parts for computers Golf clubs Cutting tools Lawn mower blades Chain saw guide bars Gears and valve plates Molten salt is the heat transfer medium used because: a) It transfers heat rapidly b) It virtually eliminates the problem of vapor phase barrier during the initial stage of quenching c) Its viscosity is uniform over a wide range of temperatures d) Its viscosity is low at removal temperatures, thus minimizing drag-out losses e) It remains stable at operating temperatures and is completely soluble in wat
