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 plates), blooms (for profiles and wire rods), and tube billets. It is an important semi-finished product in the iron and 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 processing methods into finished steel products of various specifications and shapes, such as steel plates, steel tubes, and steel bars, widely used in construction, machinery manufacturing, shipbuilding, and automobile manufacturing. Bearing steel billets are the preliminary form used to manufacture high-precision bearings, primarily made from high-carbon chromium steel. Their chemical composition generally includes carbon (0. 95% to 1.1%), chromium (1.3% to 1.65%), and small amounts of manganese, silicon, phosphorus, and sulfur. This composition imparts excellent mechanical and heat treatment properties to bearing steel, including high hardness, high wear resistance, and good dimensional stability.

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.
