WMV heat treatments
The deep vertical WMV furnace has been developed to harden Lunac coatings deposited on long parts as well as to anneal parts up to 4000 mm / 157.5" at 3000 Kg / 6667Lbs under partial inert gas (Nitrogen 98.5%). Our stress relieve temperature in this furnace is limited to 420 °C, so extended exposure time should be applied (mostly 10 hours instead of mostly 1.5 hours at 550 °C) . This furnace can reach this temperature within 2 hours and the additional heating time is 1 hour per 20 mm object radius. Very important is the hanging position of long parts will prevent them from any possible bending during the annealing process. A heating procedure report will be added to the treated parts.
