direct reduced product

Reduced product - Wikipedia

In model theory, a branch of mathematical logic, and in algebra, the reduced product is a construction that generalizes both direct product and ultraproduct.. Let {S i i ∈ I} be a family of structures of the same signature σ indexed by a set I, and let U be a filter on I.The domain of the reduced product is the quotient of the Cartesian product ∏ ∈

Direct Reduction Process - an overview ScienceDirect Topics

The direct reduction processes can be divided into gas reduction and coal reduction processes depending on the type of reducing agent used (see Section 12.5). DRI and HBI are predominantly processed in the EAF, and predominantly for the production of steel grades of long products. Compared to scrap, the advantage of DRI/HBI is low content of trace elements; however, the disadvantage is

Direct Reduced Iron and its Production Processes – IspatGuru

16/03/2013  Direct reduced iron (DRI) is the product which is produced by the direct reduction of iron ore or other iron bearing materials in the solid state by using non-coking coal or natural gas. Processes which produce DRI by reduction of iron ore below the melting point of the iron are normally known as the direct reduction (DR) processes. The reducing agents are carbon monoxide (CO) and hydrogen (H2 ...
