Activity Description
The production process of steel billets includes steps such as converter smelting, molten steel refining, and casting and shaping of molten steel, covering energy consumption, material consumption, waste treatment, and environmental emissions during the production process.
Process Description
A steel billet is a primary product obtained by casting molten steel from a steelmaking furnace, typically in the form of slabs (for producing sheet products), blooms or billets (for structural and wire products), and tube rounds. It is an important semi-finished product in the steel industry, possessing good plasticity and workability. Steel billets serve as raw materials for downstream processes and can be transformed through rolling, forging, drawing, and other forming methods into finished steel products of various specifications and shapes, such as steel plates, steel tubes, and steel bars. Silicon steel, also known as electrical steel, is a type of steel containing silicon (Si), with a silicon content generally ranging from 1.0 to 4.5% and a carbon content below 0. 08%, it can be divided into two major categories: grain-oriented silicon steel and non-oriented silicon steel.

Technology comment
Basic oxygen steelmaking is a common steelmaking process. During smelting, high-temperature combustion and oxygen blowing remove impurities such as sulfur and phosphorus from the molten steel. By controlling the amount of oxygen blown in and the processing time, the oxygen atmosphere and reaction conditions inside the furnace are regulated, thus controlling the composition and quality of the alloy. Subsequently, the molten and refined steel is transferred via ladle to a turret, which rotates to the casting position and pours the steel into a tundish. The tundish then distributes the molten steel through nozzles into individual molds, where it solidifies upon cooling to form shaped raw steel billets.
