The diagram delineates the intricate process involved in the manufacturing of steel rods within the furniture sector.
In summary, the process encompasses eleven distinct stages, commencing with the procurement of raw materials and culminating in a comprehensive inspection of the finished products.
Initially, the process begins with the amalgamation of raw materials, including iron ore, yellow ore, and carbon, which are subjected to a melting temperature ranging between 1300°C and 1500°C. Following the melting stage, the molten mixture is transferred to a smelting cabin for refinement. Subsequently, the refined metal is poured into an ingot machine, leading to the formation of condensed ingots. These ingots are then directed towards a cooling reservoir, where they are cooled to a temperature of 60°C to 100°C. As the metal cools, it passes through specially designed nozzles that facilitate the creation of elongated strands of cooled metal.
The next phase involves the transformation of the metal strands through a rolling process, wherein they are shaped by rollers. Following this, the rolled metal components undergo heat treatment in a dedicated heating machine, enhancing their structural integrity. Subsequently, automated systems carry out a thorough surface examination to ensure quality. The rods are then resized using a cutter, which has a specific identification number, 22006. The final stages of the process include ID stamping, followed by an extensive inspection, which verifies the quality and conformity of the final products before they are deemed ready for use.
