After completing the secondary metallurgy operations, achieving the required standards of chemical composition and purity, the molten steel is ready for the casting process. The standard method for tool steels is ingot casting, which involves pouring the liquid metal into specially designed molds of various shapes and sizes.<\/p><\/blockquote>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n[\/vc_column_text][vc_empty_space height=”16px”][vc_single_image image=”44670″][\/vc_column][\/vc_row][vc_row][vc_column]

This method, known as bottom pouring, limits the metal\u2019s contact with air, as it is continuously protected by slag, thereby reducing the entrapment of unwanted elements. Additionally, any fragments of refractory material that detach during filling remain afloat, making their removal easier.[\/vc_column_text][\/vc_column][vc_column width=”1\/2″]

During this phase, chemically similar elements tend to bind and concentrate in the central zones of the ingot, which remain liquid for longer. This phenomenon can cause segregation and non-uniformity. To minimize these effects, cooling must occur rapidly, and the use of molds with appropriate geometries helps increase the heat exchange surface area, improving the uniformity of cooling.[\/vc_column_text][\/vc_column][\/vc_row][vc_row][vc_column][vc_custom_heading text=”Special steel production processes \u2013 Ingot casting: conclusion.” use_theme_fonts=”yes”][vc_column_text]Continuous casting is a crucial stage in the production of special steel, as it directly affects the quality and homogeneity of the material. At Deutsche Edelstahlwerke (DEW) steelworks, which we proudly represent, this process is carried out with the utmost precision to ensure a final product of excellence.
