Powder Production Technologies - Powder Metallurgy

Sponge iron provides the base feedstock for all iron-based, self-lubricating bearings and still accounts for around 30% of iron powder usage in PM structural parts. Solid state reduction is also used for the production of refractory metal powders, using hydrogen as the reducing agent, and for the production of specialist iron powders by the

SPONGE IRON – Lloyd’s Metals

Sponge iron is also known as Direct Reduced Iron (DRI). Direct reduction, is an alternative route of iron making has been developed to overcome some of these difficulties of conventional blast furnaces. DRI is successfully manufactured through either gas or coal-based technology. Iron ore is reduced in solid state at 800-1050 c either by

PRODUCTION OF IRON AND STEEL POWDERS

quality sponge iron to be used by the Swedish steel industry as high-purity melting stock for the production of special steels like tool-steel and stainless steel. Initial tests in 1937 showed that, owing to its high porosity, the sponge iron produced by H gan s could readily be comminuted to iron powder. Production of iron powder

Direct reduced iron process - tec-science

Jun 21, 2018 In the direct-reduced iron (DRI) process, the iron ores are reduced directly to sponge iron by gaseous reducing agents! Electro-steel process. In the electric steel process, the sponge iron obtained from the direct reduced iron process is used for crude steel making. In general, scrap is also added to this process as well as pig iron from the

Raw Material for Steel, PIG Iron, Sponge Iron, Steel Scrap

Sponge iron is produced through direct reduction of iron ore in the solid state. Sponge iron is an iron source relatively uniform in composition, and virtually free from tramp elements. It is mainly used in Electric Arc and Induction furnaces to dilute the contaminants present in the scrap

Sponge Iron - an overview | ScienceDirect Topics

3.3.3.1 Direct Reduced Iron. DRI, also known as sponge iron, is the product of reducing iron oxide in the form of iron ore and steel plant wastes into metallic iron, below the melting point of iron and typically in the range of 800–1200 C. Iron oxide is charged into shaft furnace, rotary kiln, or fluidized beds in the form of pellet, iron ore lumps, or fines
