Smelterij man gooit staal in smeltoven waar veel vuur uitkomt

At Foundry Neede, we use traditional methods to melt down various materials during the production process. Thanks to our integrated coordination processes and close cooperation between all our departments, our melting process is characterised by very high efficiency.

How does the smeltery work?

In our smeltery, we can produce grey cast iron (lamellar), as well as nodular cast iron (ductile), in addition to comparable alloys in all shapes and sizes. All other materials are available upon request. Our foundry delivers these materials in line with DIN EN 1561 and DIN EN 1563 for lamellar and nodular cast iron respectively, which are then melted down in our smeltery.

Melting lamellar cast iron

There are hardly any ferrous alloys that are cheaper than lamellar cast iron and its industrial applications stretch far and wide. It is mainly used in products, machines and materials that are not subjected to high mechanical loads, such as gearboxes. Because it is easy to cast thin-walled products with lamellar cast iron, it’s also common in parts where aesthetics play an important role. Standard lamellar cast iron includes the following types:

  • EN-GJL-200 (GG20)
  • EN-GJL-250 (GG25)
  • EN-GJL-300 (GG30)

Melting nodular cast iron

Melting nodular cast iron

When producing nodular cast iron, special metallurgical techniques are used to ensure that the graphite in the iron takes the shape of nodules, rather than flakes (lamellar). Nodular cast iron is characterised by high tensile strength and elasticity. Standard nodular cast iron includes the following types:

  • EN-GJS-400-15 (GGG40)
  • EN-GJS-400-18-LT (GGG40.3)
  • EN-GJS-450-10 (GGG40 / 50)
  • EN-GJS-500-7 (GGG50)
  • EN-GJS-600-3 (GGG60)
  • EN-GJS-700-2 (GGG70)

Quality grades

The grades of metal obtained after the melting process are indicated in formats such as EN-GJS-450-10, EN-GJS-600-3 of EN-GJS-700-2, but we are also familiar with the GGG40/50, GGG 50 and GGG 70 grades. Gieterij Neede can produce batch castings with a weight per piece of 100kg, as well as manual castings that weigh 1000kg or more.

Because we cast and melt various alloys in our smeltery, all materials are produced in accordance with fixed melting procedures. In order to guarantee the correct chemical composition, the melted materials are carefully analysed once they have been completely melted down and mixed. If necessary, we can still adjust the mixtures to meet the required standards. During the casting process, the product is treated further, using grafts to give the casting the required mechanical properties.

Does your product need any further operations?

Depending on your request or needs, we can serve as a one-stop casting shop where your product can be designed and your finished products can be finalised. Perhaps you are also looking for assembly services or turning and milling services. You can also choose to have us make your product ready for use by applying a coating in our very own spray shop.
