Foundry scrap

Foundry scrap is usually a very uniform material. The high-quality scrap is processed for our foundry customers according to type and suitable for charging.

How is foundry scrap differentiated?

Foundry scrap is divided into the following groups:

• Scrap for gray cast iron
• Scrap for nodular cast iron
• Scrap for cast steel

Foundry scrap for the production of gray cast iron is scrap with a higher carbon content (C) and silicon content (Si), such as cast iron scrap.

• Machine casting scrap: usually from old machine parts, crushed to a manageable size, rarely less than 10 mm thick
• Castings: weak-walled breakage from e.g. agricultural machinery, construction casting breakage or pipe casting breakage
• Mold scrap
• Circulating material from foundries: lumpy casting material that is separated off when cleaning the raw casting (e.g. runners, feeders)

Scrap from steel production is also used for the production of gray cast iron. These scraps have lower carbon contents and lower silicon contents.

Scrap for nodular cast iron is Fe scrap that is particularly pure (focus on low Mn content) in order to meet the customer’s strict analytical specifications.

• Cupola scrap (e.g. heavy plate cupola): steel scrap from beams, profiles, heavy plates, thick-walled pipe sections, dimensioned according to customer specifications for the respective (cupola) furnace
• Trimming scrap: Scrap produced as production scrap during rolling
• Bundled scrap: production scrap that is pressed into bundles of various dimensions, depending on the customer’s requirements
• Punching scrap
• Sheet scrap

Scrap from the same steel groups as in the production of forged and rolled steel is used to manufacture of cast steel products.

Where does foundry scrap come from?

As foundry scrap must have a high degree of purity, it mainly comes from uniform sources, such as punching scrap, industrial scrap, castings or similar. They are sorted by us, shredded according to the customer’s specifications and, if necessary, packaged before being delivered to our foundry customers.

What is done with foundry scrap?

Foundry scrap is returned to the product cycle by being used in foundries. Using foundry scrap significantly reduces the use of pig iron, which saves manufacturing costs and greenhouse gases. RHM offers its customers the option of storing foundry scrap until the customer calls for it and then delivering it in smaller amounts as required, so that the foundries require less storage capacity.

What does the use of foundry scrap mean for the environment?

The use of secondary raw materials instead of primary raw materials means a comprehensive reduction in environmental impact. For this reason, the processing and marketing of scrap makes a significant contribution to climate protection. The use of foundry scrap not only saves a huge amount of CO₂ and energy, but also conserves considerable amounts of natural resources. Scrap can be fed back into the economic cycle an infinite number of times without changing its properties.

Why scrap from RHM?

RHM has a very broad and strong base. It markets ferrous scrap, foundry scrap, alloyed scrap, non-ferrous scrap and industrial residues / metallurgical residues. The portfolio also includes steel product trading. RHM supplies well-known steelworks and foundries as well as the chemical industry.

RHM is always open to new technical challenges in order to further develop and optimize the recycling of scrap. In addition to a high standard of quality, the company also attaches great importance to research and development (R&D) of innovations. RHM’s way of thinking is such that challenges are implemented quickly and “unbureaucratically” in order to meet sustainability and customer requirements in the best possible way.
