route for making consists of or plants, and . Such plants require high and raw materials of stringent specifications. is
needed to make a strong enough to support the burden in the blast furnace. Integrated steel plants of less than one
million tons annual capacity are generally not economically viable. The coke ovens and sintering plants in an integrated
steel plant are polluting and expensive units.

2. High activity and good effect of regeneration
3. High strength to resist compression, no-powder, no-hardening
4. Large specific surface, high voids content, remove thedissolved oxygen in the water quickly
5. Good back flush effect, low back flush rate, long life cycle of use.
Use of sponge iron
One of the more common uses for sponge iron is the creation of wrought iron. Iron of this type is helpful in the creation
of ornamental objects for use around the house, such as decorative grills for screen doors, burglar bars for windows,
