Please review my essay. Thank you!

The diagram illustrates how steel rods are manufactured in the furniture industry.

Summarize the information by selecting and reporting the main features.

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

Overall, the process includes eleven steps, beginning with collecting raw materials and ending up with the inspection.

First of all, iron ore, yellow ore, and carbon are collected to serve as raw materials; then they are melted in the slit at a temperature of 1300 to 1500 Celsius. After melting, the raw materials are put into a smelting cabin to undergo a refinement process. Next, candescent metal is poured into ingots via a pouring machine.

In the strand casting step, ingots are connected to a cooling reservoir, where the temperature falls to 60 to 100 Celsius. Here, metals go through nozzles, and strands of cooled metal are made. Subsequently, the metal strands pass through rollers and then undergo a heat treatment via a heating machine. Once they have been heated, metals’ surfaces are checked by measuring automation. After that, a cutter is used for sizing metal shapes and then the metals go through the ID stamping process. Finally, the steel rods undergo inspection and are ready for use.
