Open-die forging, also known as free forging or smith forging, creates a hole in the centre of a metal circle for use in the ring rolling process. This doughnut is heated above for recrystallization, and then put on the idler or mandrel roll. This idler roll moves under pressure towards a drive roll that keeps turning to reduce the wall thickness and make the I.D. and O.D. of the ring bigger.
Flat washer-like components to tall, seamless rolled rings are all possible. Usually, the ratio of a ring’s wall thickness to its size is between 1:16 and 16:1. Special processing makes it possible to achieve a higher percentage.
Most rings have a rectangular cross-section, the simplest and most common shape. Shaped tooling can make seamless rolled rings in complex shapes with curves on the inside and outside diameters.
Rolled Ring Forging Advantages
Making strong products that last a long time is an essential part of every modern manufacturing process. Every customer wants parts that remain functional for a long time. Seamless rolled ring forging is a great way to make solid parts and components that will last in all conditions.
With seamless rolled ring forging, different strong metals can make a wide range of gears, couplings, bearings, and connectors. The process is seamless, which is a big reason why the parts made are substantial and last a long time.
This post will discuss how open die forging and seamless rolled rings forging are different.
Open-Die Forging
The name “open-die forging” comes from the fact that the metal used is not held in place by the dies. The starting stock is shaped into the desired shape between two flat-faced dice.
Open-die forging makes it possible to make a wide range of shapes and sizes, from small pieces that weigh only a few pounds to huge ones that weigh 150 tonnes.
Open-die forging can produce components of any size and is the method of choice when your design requires the highest possible level of structural integrity in a massive metal component.
With open-die forging, you can make many different shapes:
•Bars with basic shapes like square, round, rectangular, and hexagonal
•Sold shafts
•Metal shells with a shape like pressure vessels
•Hollow cylinders
Seamless Rolled Ring Forging
Forging a seamless rolled ring starts with a circle of metal that has already been pierced to make it look like a doughnut. This ring is heated and then turned to make the walls thinner and the ring’s diameter bigger.
One of the reasons to use these rings is:
• Toughness
Forgings are more potent than other parts because they don’t lose their strength when the temperature changes.
• Value for Money
The cost of making these rings is less than that of similar products. As the rings are close to the shape of the finished part, less machining is needed.
• Reliability
Because rolled rings need to be made at high temperatures, the grain pattern gives them more strength and resistance than other parts.
Conclusion
Specialty Ring Products is the go-to choice for expert seamless rolled ring forging. Forged surfaces are ready to take coatings, plating, anodizing, and other high finishes. This gives them a good, uniform look and the most resistance to corrosion or coatings that don’t stick well. Forging also gives fundamental wrought properties by ensuring the best results are guaranteed.
