About remelting scrap ingots of iron or steel

cpc code 3935 covers the industry of remelting scrap ingots of iron or steel. This industry plays a crucial role in the broader steel and metal recycling ecosystem, as it allows for the recovery and reuse of valuable metal resources that would otherwise be discarded. By remelting scrap ingots, this industry contributes to the sustainability of steel production and helps to reduce the environmental impact of metal extraction and processing.

Production process

The primary production technique used in this industry is the remelting of scrap iron or steel ingots. This process typically involves heating the scrap material in a furnace or other specialized equipment until it reaches a molten state, at which point it can be cast into new ingots or other intermediate steel products. The specific methods and equipment used may vary depending on the scale and sophistication of the operation, but the core principle of melting down and reforming scrap metal remains the same.

Production inputs

The main inputs required for the remelting of scrap ingots of iron or steel include the scrap metal itself, as well as energy sources such as electricity or natural gas to power the remelting furnaces. Depending on the specific process, additional materials such as fluxes or alloying elements may also be required to achieve the desired metallurgical properties of the final product. The availability and quality of scrap metal feedstock is a critical factor in the success of this industry.

Production outputs

The primary output of the remelting of scrap ingots of iron or steel is the production of new ingots or other intermediate steel products, which can then be further processed or used in the manufacture of a wide range of end-use products. These new steel products may be consumed by industries such as 3940 Steel foundries, 3950 Steel rolling and drawing, or 3960 Steel pipe and tube manufacturing.
