The diagram illustrates the manufacturing process of steel rods in furniture factory.

It is clear that there are a number of stages of this process and number of tools. It is also noticeable that the process starts with melting raw materials and ends up with observing final products for delivery.

At the beginning of the steel manufacturing process, there are three kinds of raw materials mixed into a jar. After adding Iron ore, Yellow ore and Carbon then they are melted in the melting slit with 1300-1500 celcius temperatures. At the following stage, the melted materials are purified into the smelting chamber then poured ingots in the next step. Afterwards, poured metal goes into the nozzles to the cooling zone then they rolled by rollers.

For the remaining stages, rolling metal is heated in the heating machine then surface is checked by automaton. After checking surface, the steel rods are cut by cutter. At final stage of the process, stamping company logo in the rods and then go for checking quality for the delivery.
