Rotary Retort Design

Alloy Engineering has developed and designed batch rotary retorts and continuous rotary retorts for high-temperature applications since 1995.

Unlike OEM cast retorts, our rotary retort replacements are welded from a combination of different wrought nickel alloys and designed to operate over an extended service life – delivering consistent hardening performance required for uniform heat treating.  Importantly, this translates into cost savings and better production performance at your facility.  

Take a look at some of our product features, certifications and capabilities to see why Alloy Engineering is your number-one source for superior rotary retort solutions.  

Features

• Custom retort fabrications
• Welded to ASME/AWS specifications
• No pattern costs or restrictions
• Extensive experience with all stainless and high-nickel alloys
• Nickel alloys produce smooth interior surfaces without eruptions
• Weigh less and heat up faster than cast retorts for shorter cycle times 

• Ductile wrought materials with low carbon content and tight grain structures result in greater resistance to thermal fatigue
• A fabricated rotary retort can be repaired or rebuilt – replacing only the damaged section
• Quality testing, including dye-penetrant, pressure testing, x-ray and UT
• Our ASME-CE’s will provide recommendations for longer product life
