This diagram outlines the steel rod manufacturing process used in furniture production. The process involves eleven significant stages and utilizes three primary constituent materials, which go through several preparatory steps before resulting in the final product.
In the initial stage, raw materials like iron ore, yellow ochre, and carbon are mixed together. Subsequently, this mixture is heated to around 1300 to 1500 degrees Celsius to reach a molten state. The molten metal is then purified in a special chamber. Following this, the liquid metal is moved to a pouring machine where it is shaped into bars that are then cooled in a tank until they reach a safe temperature of 60 to 100 degrees Celsius.
The cooled metal bars are then processed through a set of rollers and a heating unit. After heating, the surface of the metal rods is automatically inspected for any defects. Once inspected, the rods are precisely cut to the required size by a cutter. In the following step, these standardized rods are stamped. Lastly, the final product undergoes a thorough inspection before being approved for release.
