The diagram illustrate how steel rods aee manufactured in the furniture industry.

The given diagram describes the process of

steel

rod production by the manufacturers of furniture. It can be clearly seen that

steel

rod making is a liner process comprised of ten steps i.e., melting, refinement, ingot making, strand casting, rolling, heat treatment, surface check, and cutting before ID stamping and inspection.

To begin

with, raw materials i.e., yellow ore, iron ore, and carbon are gathered and transferred to the melting slits where these are subjected to the temperature of 1300- 1500 Celsius for melting.

Next,

melted raw materials are refined in a smelting cabin and

then

candescent metal is poured by a pouring machine into bar moulds for making

steel

ingots. Following ingot making, wires of cooled

steel

produced through the step of strand casting in which each ingot is passed through the nozzle connected to a cooling reservoir of temperature 60 – 100 Celsius. The wires of cooled

steel

are

subjected to the rollers to flatten the strands before subjecting them to the heating machines for heat treatment.

After

, the

steel

wires are passed on for surface check with the help of a measuring automation machine before sending them for cutting into equal sizes.

Lastly

, the

steel

rods produced are stamped with the manufacturer’s ID and

then

passed for quality inspection.
