Special steel production processes: Scrap
The production of high-quality special steel begins with a careful selection of scrap. This phase is crucial to ensure that the final product meets all the required technical specifications. The use of scrap specifically selected for each type of steel is fundamental in order to control the presence of unwanted elements and to optimize the chemical composition from the very beginning.
Importance of scrap selection
The selection of scrap is of fundamental importance because it allows for the control of unwanted elements such as phosphorus. Reducing these elements during subsequent refining phases is very costly, so it is preferable to minimize their presence from the start. Moreover, proper scrap selection helps achieve a chemical composition closer to the desired one, reducing the need to add additional alloying elements.
Chemical composition of scrap
The scrap used must have a chemical composition compatible with that of the steel to be produced. This not only improves the efficiency of the production process but also helps reduce costs, as it minimizes the amount of alloying elements that need to be added to achieve the desired final composition.
Scrap selection and control
To ensure the quality of their steels, Deutsche Edelstahlwerke (DEW) subject the scrap to rigorous inspections and selections. This process guarantees that only the best materials are used in the initial melting. The quality of the scrap directly affects the mechanical and chemical properties of the produced steel, making this phase one of the most critical in the production process.
The production processes of special steel – Scrap: conclusion.
The selection of scrap is a fundamental phase in the production of special steel by Deutsche Edelstahlwerke (DEW), the steelworks we represent. Careful selection and control of the scrap ensure that the produced steel is of the highest quality, meets the required technical specifications, and is suitable for a wide range of industrial applications. This insight is just the beginning of a series of articles that will explore every stage of special steel production.
