Castings | What Are Sand Castings?

A casting is a type of metal component that is vital to countless industries. They are created through the casting process, which consists of pouring molten metal into a mold and then allowing it to cool and solidify. The casting process is extremely versatile and offers the freedom to form intricate metal parts. Due to the versatility of cast parts, there are a wide-range of casting types. Some popular casting types include investment castings, heat resistant castings, and sand castings. Today we will explain sand castings so you can decide whether or not these metal components can benefit your next project.

Sand Castings: Explained

A sand casting is different from other cast parts because it uses sand as the mold material. The sand is typically mixed with a bonding agent, such as clay, and is then moistening with water or another liquid in order to create the appropriate mold strength and plasticity. The surface of a sand casting might not be as smooth as other casting types. However, its rough surface and minor imperfections can be easily fixed with machining. Sand castings are one of the most common cast parts and can be utilized for both short-run and long-run productions. Some of the appealing advantages of this type of casting include its cost effectiveness, easy to change design, and manufacturing speed, just to name a few.

Alloy Castings | What You Need to Know

Countless industries would not be able to function without castings. Formed by pouring a liquid metal into a mold and then allowing it to cool and solidify, these metal components create complex shapes that would be close to impossible to emulate using other methods. While you can create castings using just one metal, such as iron, alloys are an extremely popular casting material as well. Keep reading to find out what you need to know about alloy castings!

What Are Alloys?

Most metals used in castings and other metalworking processes are not metals at all. Rather, they are alloys. Alloys are metals combined with other substances to make them stronger, lighter, or better in some other way. The substances that are paired with the main metal are called alloying agents. The alloying agents can be another type of metal or a completely different chemical element. They are present in much smaller quantities (sometimes less than 1 percent of the total) than the main metal, but have a significant impact on the quality of the castings. 

What Should I Consider When Choosing a Casting Alloy? 

There are numerous different types of alloys that are used to create castings, each with their own advantages and disadvantages. As a result, there are a variety of factors to consider when choosing a casting alloy. Some specific considerations include strength, durability, production volume, corrosion resistance, cost, stability, and so on. For example, if your project requires components that are corrosion resistant with high strength, an aluminum or copper-based alloy could be an effective choice. Which alloy you utilize for your castings depends on which factors are required for your project.

Forgings | Types of Forging Processes

Forgings are one of the most sought after metal components. At its most basic level, forgings are created by forming and shaping metals by hammering, pressing, or rolling. As a result, forgings come in a myriad of sizes and shapes with enhanced properties. Depending on your specific project and desired application, different forging processes are used to create the metal part. Keep reading to learn about the most popular forging methods!

3 Different Methods for Forgings

1. Rolled Ring Forging

Rolled ring forging is a process that uses two curved dies to deform the metal. Normally, the dies are two opposing rollers. This method produces forged products with a final shape that is similar to the dies. The rolled ring process is largely used due to its many benefits. Some of these benefits include a long lifespan, high productivity, low cost, and quality finishes.

2. Closed Die Forging

Closed die forging is a process that shapes a metal part by forcing it into the contours of a die. This process gets the name “closed die” because the material is confined between an upper and lower die. The closed die process requires a significant amount of force. It is often used to produce near net shapes.

3. Open Die Forging

Open die forging is a process that plastically deforms the metal with a series of compressive forces. It is carried out between two flat dies or simple shapes. Usually, the dies do not completely enclose the material, which is why this process is called “open die.” The open die forging method is used mostly for large objects and smaller quantities.

Forged Furnace Roll Trunnions

Ferralloy, Inc. began shipping an order for 120  furnace roll trunnions, or bell ends as they are sometimes referred to, for a new heat treating furnace ordered by a large international steel producer.

The requirement for forgings in this application is somewhat unusual as this component is typically supplied as a sand cast component. For reasons related to the inherent mechanical properties of a forging, we were asked if we could source the billet material in the desired chemistry, forge the trunnions, and rough  machine them to the drawing dimensions. We produced the open die forgings, which were then normalized and machined.  The forgings will be welded to centrifugally cast tubes and then the entire assembly will be finish machined before field installation in the new furnace.

The forgings weigh 70 pounds in the rough machined condition and were produced from a grade of heat resistant alloy steel.
