Band 6+: The diagram illustrates how steel rods are manufactured in the furniture industry. Summarize the information by selecting and reporting the main features and make comparisons where relevant.

The diagram explains the way in which steel rods are produced for the furniture industry.

Overall, the process consist of eleven stages , beginning with row material and ending up with the product’s inspection.

First of all, iron ore, yellow ore and carbon are collected to serve as a raw material for steel rods manufacturing. After that, the raw material is melted in a melting slit, where it is heated to a temperature in range of 1300-1500 °C. The melted mass is thentransferred to a smelting cabin to undergo refinement. Next, the candescent metal is put in a pouring machine and poured into ingots.

In the next stage, the ingots are connected to a cooling reservoir, where the temperature falls to 60-100 °C. Metal goes through special nozzles and cools down, forming strands. Following this, the metal strands proceed to rollers that change their shape. Next, the products are put into a heating machine, where they undergo heat treatment. Subsequently, a measuring automaton completes a surface check of the products.

After that, the metal rods are sized by special cutters and get ID stamping. Finally, the products undergo inspection and are ready for use.
