Sintering production process: The sintering operation is to mix and granulate the pulverized iron ore, various fluxes and fine coke, then add it to the sintering machine through the distribution system. The fine coke is ignited by the ignition furnace, and the sintering reaction is completed through the exhaust windmill. After the high-heat sinter is crushed, cooled and screened, it is sent to the blast furnace as the main raw material for smelting molten iron.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

The basic oxygen furnace (BOF) production process begins with the transfer of molten iron to a pretreatment station for desulfurization and dephosphorization. Following oxygen blowing in the converter, the molten steel undergoes secondary refining\u2014tailored to the specific grade and quality requirements of the order\u2014at stations such as RH vacuum degassing, ladle injection, VOD (vacuum oxygen decarburization), or STN stirring units to adjust the chemical composition. Finally, the steel is sent to continuous casting machines for blooms and slabs, where it is cast into red-hot semi-finished products. These undergo inspection and surface conditioning (grinding or scarfing to remove defects) before being sent downstream for rolling into finished products such as bar steel, wire rods, plates, coils, and sheets.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

Continuous Casting Process: Continuous casting is the process of transforming molten steel into steel castings (billets or slabs). Molten steel, having undergone upstream processing, is transported via ladle to a turret; it is then distributed through a tundish into multiple streams and poured into molds of specific shapes, where cooling and solidification begin. This forms a casting with a solidified outer shell and a molten steel core. The casting is then withdrawn into an arc-shaped strand guide, where secondary cooling facilitates further solidification until the steel is fully solid. After straightening, the casting is cut to order-specific lengths; square sections are known as “billets,” while rectangular sections are known as “slabs.” Depending on requirements, these semi-finished products undergo surface treatment before being sent to the rolling mill for further processing.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

Hot rolling involves heating the material either during or prior to the rolling process; typically, the material is heated above its recrystallization temperature before rolling takes place. Hot-rolled products are characterized by high strength, good toughness, ease of forming, and excellent weldability, making them widely used in manufacturing sectors such as shipbuilding, automotive, bridge construction, architecture, machinery, and pressure vessels.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Wire rod production process: Small steel billets are heated in a furnace and then rolled through roughing, intermediate, and finishing mill stands, as well as a reducing and sizing unit. The material is then coiled, transported via a cooling conveyor, and sent to the finishing area.
