PRODUCT DETAILS
1. What is Sponge Iron
Sponge iron is a metallic product produced through direct reduction of iron ore in the solid state. It is a
substitute for scrap and is mainly used in making steel through the secondary route. The process of sponge
iron making aims to remove the oxygen from iron ore.
The quality of sponge iron is primarily ascertained by the percentage of metallization (removal of oxygen), which is the ratio of metallic iron to the total iron present in the product.
Sponge iron manufacture is highly sensitive to raw material characteristics. Therefore, it is essential to
examine the chemical and physical characteristics of raw materials, both individually and in combination. The basic raw materials for the production of sponge iron are iron ore, non-coking coal and dolomite.
Sizing of the Raw materials also play vital role in sponge iron manufacturing process.
2. PROPERTIES & ADVANTAGES
Properties of Sponge Iron
^ High iron content and high degree of metallization
^ Uniform and consistent quality
^ Lower sulphur and phosphorus content
^ Negligible tramp element
^ Minimum dust generation during material handling
^ Good flow ability in bins, pipes and conveyors for continuous and trouble free charging
^ Superior technical support to induction furnace operators
Advantages of Sponge Iron
^ Chemical composition is uniform.
^ It contains no undesirable impurities.
^ It permits dilution with low cost scrap.
^ Easy to handle & transport.
^ Permits automatic continuous charging.
^ Less noise during melt down.
^ More predictable price structure.
^ No trump elements.
^ No requirement of metallurgical coal.

4. TECHNICAL PROCESS
A long slightly inclined to the horizontal slowly rotating kiln is employed to carry out the reduction.
The charges are fed from that end which is at a higher level it travel under gravity aided by the rotating
motion through several heating zones & the reduced charge comes out from the other end of the kiln.
This is a solid phase and gaseous reaction and no liquid phase occurs inside the kiln.
5. PACKAGE & SHIPPING
# 25kg/bag, 1000kg/JUMPO bag ; Customization Allowed.
# After confirmation of cargo in good condition(packing sound), the cargo can be loaded
in CONTAINER, then sealing the container and finally starting shipping from loading port.
# You will be receive the bulk products at your destination port after about 7- 15 days.
6. CORPORATION & SERVICES
# Ningxia Baiyun carbon Co.,Ltd, is one professional manufacturer, with rich experiences of industrial
products exporting worldwide.
# Our corporation has already get the customers' approval continuously according to our integrity,
strength and product quality (having the complete and scientific quality managment system).
# Our corporation, located in shizuishan city, with title of "coal city", which is famous for producing
anthracite. We mainly engaged in activated carbon, carbon additives, carbon products, desulfurization
carbon, anthracite filter, flocculant, abrasive, refractory materials, emery and other products.
