Learning to buy CDRI sponge iron from zero to one hundred

CDRI sponge iron is a valuable material that has a wide range of applications across various industries.

Understanding its properties, production process, and benefits can help potential buyers make an informed decision when purchasing this essential material.

What is CDRI sponge iron? CDRI sponge iron, also known as direct-reduced iron, is a high-quality metallic product derived from iron ore.

t is produced through the reduction of iron oxide, primarily in the form of pellets or lumps, in a solid state at relatively low temperatures.

This process involves the removal of oxygen from the iron ore, resulting in a highly pure form of iron with a sponge-like structure.

Production Process

The production of CDRI sponge iron typically begins with the selection of high-quality iron ore, which is then processed into pellets or lumps of the desired size.

These iron ore pellets are then fed into a rotary kiln or a fluidized bed reactor, where they are subjected to a controlled reduction process at temperatures ranging from 800°C to 1050°C. During the reduction process, a reducing agent such as natural gas or coal is injected into the kiln or reactor, which reacts with the iron oxide in the pellets to remove the oxygen content.

This reduction reaction leads to the formation of metallic iron particles with a high iron content of approximately 90-95%.

Once the reduction process is complete, the sponge iron product is cooled and discharged from the kiln or reactor.

The resulting CDRI sponge iron can be further processed and used in a variety of applications across different industries.
