How Do Steel Castings and Cast Irons Differ?

Steel Castings

Steel castings are components that are formed by pouring molten steel into a mold cavity. The liquefied steels then cool and solidify within the mold. You can create the shape and the casting to perfectly fit your specifications. Although the casting process of steel can be difficult, the results are well worth it.

Moreso, steel castings are mainly used when other types of cast irons do not have enough strength or shock resistance. Its physical properties allow the castings to be both strong and ductile, making it extremely tough. Also, it limits the chances of fracturing under pressure.

Industries that use steel castings range from food processing and electronics to oil and gas. Some specific industries that use this type of casting include the railroad, construction, drilling, transportation, and mining industries

Cast Irons

When it comes to corrosion, iron has better corrosion resistance than steel. It is also often cheaper because of the lower material costs, energy, and labor required to produce a final product. Additionally, cast iron is relatively easy to cast–it pours easily and doesn’t shrink as much as steel.

Why is Aluminum Used in Rolled Rings?

Lightweight

Aluminum is famous for its soft and lightweight characteristics. This type of metal is frequently used by rolled ring manufacturers because it is non-sparking, non-magnetic, and non-toxic. More so, it works best alone or with other metals.

Quick trivia: if you’re wondering why aluminum has this dull silvery appearance, it’s because of the thin layer of oxidation that is abruptly created when the metal is exposed to air. Nonetheless, the low atomic weight of aluminum is the reason why it is low in density.

Extremely Durable

Another reason why forging companies use aluminum is that it’s durable. Aside from being famous for its lightweight characteristics, aluminum doesn’t disappoint manufacturers when it comes to durability. What makes aluminum durable is the long life span combined with the right amount of energy.

Low Maintenance and Corrosion-Resistant

Aluminum is also low maintenance because it requires little care and cleaning compared to other metals.

What makes aluminum corrosion-resistant is its tendency to create a solid oxide layer over the surface. The oxide created is responsible for the high rust resistance.

Distortion in Forged Rolled Rings

The thermal and rolling treatment of forged rolled rings sometimes leads to the creation of residual stresses, causing dimensional distortion in the results. However, there are tons of corrective measures employed by forging industries to address this concern. Ongoing studies are seeking to base newly-found corrective measures on the laws of physics.

How does Dimensional Distortion Happen?

Ring Rolling Process

First, the rings and other metal components are rounded and cut to how much it weighs. It is then processed to reach the intended integrity, directional grain, and other specifications. It is then punched and pierced to create a ring.

After that, it is placed on the ring mill to be rolled. The idler roll applies pressure against the drive roll and slowly the ring diameters are increased. Continued pressure is applied, and this reduces the wall thickness.

The axial rolls control the height as it is being rolled and this is repeated until the proper size and specifications are reached.

Distortion is Not the Only Problem

Once the metal components have been rolled at a certain forging temperature, most of them are heat treated. Due to this method, some parts of the components become ovular and distorted.

This occurs more often in huge metals with outer-diameter to wall-thickness proportions. More so, distortion is the only concern resulting from this method. Despite furnishing results that meet dimensional tolerances, residual stresses may still happen even after the product has been shipped to the customer.

The reason is that succeeding machining processes conducted by customers or other metal-production companies may cause extra distortion and deformation to the product.

Preventive Measures Must be Employed

In light of the intricacy of the issue, various ring-rolling companies approach it with only corrective measures while disregarding the essential preventive measures. There are companies which manufacture the metal components with great tolerances so it can be earlier manufactured to its final dimension and preventing any possible distortion.

Others employ corrective ring distortion measures through expansion and compression processing, partially relieving the components of residual stresses.
