The diagram illustrates the manufacturing process for steel rods used in the furniture industry. Overall, this cycle consists of eleven distinct stages, beginning with the initial processing of raw materials (iron ore, yellow ore, and carbon) and ending with a quality inspection of the finished product.
The manufacturing process starts with immersing the raw materials in a melting slit, where they are heated to extremely high temperatures of 1300 to 1500 degrees Celsius. Once melted, the material is transferred to a smelting cabin for refinement. In the following stage, the refined metal is poured into molds to form ingots. These ingots are then connected to a cooling reservoir, where they pass through nozzles and are transformed into strands of metal as they cool. The temperature of the metal gradually decreases to between 60 and 100 degrees Celsius during this cooling phase.
After cooling, the metal strands move through a series of rollers to shape them as needed. Next, the shaped rods undergo heat treatment in a specialized heating machine to enhance durability. Following this, the metal rods are inspected by a measuring device to ensure surface quality, and a cutting machine precisely cuts them to the required length.
The final stages involve stamping an ID mark onto each rod for tracking purposes, followed by a comprehensive inspection to verify the quality and compliance of the finished products. Once these steps are complete, the steel rods are ready for use in the furniture industry.
This well-defined process ensures that steel rods meet required standards of quality and consistency before reaching their final application.
