in its sinter plants at jamshedpur (india), tata steel has progressively improved the sintering process over more than 40 years through the appropriate selection of raw materials and the improvement of hardware . it has successively lowered the al2o3 content from 5.0 to 1.9%, with the corresponding improvement in the rdi, which has dropped,conversion of mill scale waste into valuable products via,in an integrated steel plant, portion of mill scale, the large size one, was recycled in sintering plants . but a study on recycling mill scale of steel in the sintering process showed that the sinter productivity decreased with the increase in mill scale addition due to a decrease in sinter bed permeability [ 2 ].
sinter plant. sinter plants agglomerate iron ore fines (dust) with other fine materials at high temperature, to create a product that can be used in a blast furnace.the final product, a sinter, is a small, irregular nodule of iron mixed with small amounts of other minerals. the process, called sintering, causes the constituent materials to fuse to make a single porous mass with little change,sinter machine - an overview,a.e. morris, m. wadsley, in encyclopedia of materials: science and technology, 2001 4.1 smelting of lead. the conventional process for smelting lead involves roasting a mixture of lead sulfide concentrate and flux on a sinter machine, followed by blast furnace smelting.environmental and energy considerations have prompted studies of a more direct route, a so-called “direct” smelting process.

the sintering process is a pre-treatment step in the production of iron, where fine particles of iron ores and also secondary iron oxide wastes (collected dusts, mill scale etc.) along with fluxes (lime, limestone and dolomite) are agglomerated by combustion.,limestone and dolomite and their use in iron and steel plant,limestone and lime products are used as fluxing material both in ironmaking and in steelmaking. basically limestone is used as a slag former, while dolomite is used as a slag former, slag modifier and as a refractory material. the process of iron making is

sintering is a widely used method to agglomerate iron-containing fine-grained materials. in sintering the ore fines, concentrates, fluxes, and coke breeze are thoroughly weighed, moistened, and mixed. the sinter mix is fed on the grate of the sintering machine to make a 0.3–1 m high bed. the grate is an endless strand of slowly moving pallets.,the world leader in ironmaking solutions,as plant designers, our job is to create concepts that offer the best possible solution to meet environmental requirements and economical needs simultaneously. primetals technologies, with its integrated process knowledge, is a leading full-line supplier of sinter plant solutions. our technologies meet all local and market-specific requirements.
the principal feed materials for sintering are fine untreated ores (8–10 mm) and ore concentrates, as well as fuel (coke breeze and anthracite breeze up to 3 mm), flux (limestone and dolomite up to 3 mm), and in some cases fine wastes (flue dust, scale, and others). the end product is sinter cake.,iron and steel manufacturing -,from sintered, pelletized, or lump iron ores us-ing coke and limestone in a blast furnace. it is then fed to a bof in molten form along with scrap metal, fluxes, alloys, and high-purity oxygen to manufacture steel. in some integrated steel mills, sintering (heating without melting) is used to agglomerate fines and so recycle iron-rich mate-
