Activity Description
The production process of steel billets includes steps such as converter smelting, medium-frequency furnace melting of alloys, molten steel refining, and casting and shaping of molten steel, covering energy consumption, material consumption, waste treatment, and environmental emissions required during the production process.
Process Description
A steel billet is a primary product obtained by casting molten steel from a steelmaking furnace, and its shape is typically a slab (for producing plates), bloom or billet (for producing sections and wire rods), or tube billet. It is an important semi-finished product in the iron and steel industry, possessing good plasticity and workability. Steel billets can serve as raw materials for downstream processes and are further processed by rolling, forging, drawing, and other methods into finished steel products of various specifications and shapes, such as steel plates, steel pipes, and steel bars. 430 stainless steel is a commonly used ferritic stainless steel, whose main components include iron, approximately 16%–18% chromium, and smaller amounts of manganese, silicon, carbon, and phosphorus. Stainless steel billet is the primary form in the stainless steel manufacturing process and is typically further processed into various stainless steel products.

Technology comment
The steel billet production process combining a dephosphorization converter with an intermediate frequency furnace is an efficient steelmaking method. In the dephosphorization converter stage, excess phosphorus is removed from molten iron by adding an appropriate amount of lime and oxygen blowing. In the intermediate frequency furnace stage, electromagnetic induction heating is used to mix alloying elements with the molten iron. The intermediate frequency furnace provides precise temperature control and a relatively uniform heating environment, facilitating uniform distribution of alloying elements in the molten steel. Various alloying elements such as carbon, silicon, manganese, nickel, and chromium can be added during this stage as needed to achieve the desired chemical composition and mechanical properties.
