18.4. NO x emissions and their mitigation technologies 18.4.1. Characteristics of NO x emissions. NO x is associated with air pollution problems such as "photochemical smog." In Japan, the amount of NO x emitted from sintering plants accounts for the majority of total NO x emissions from integrated steelworks (Morioka et al., 2000).

Though it is regarded as a waste product,mill scale is recycled as a ferrous feed for iron sinter plants, which are plants very much associated with the manufacture of iron and steel.Therefore, mill scale is reused as a raw material for the manufacture of iron and because of this, it is increasingly traded as a bulk cargo. Sintering plants

Mill scale is a very at- tractive industrial waste due to its richness in iron [about = 72 % Fe) [2]. In the whole world, 13.5 million tons of mill scales are generated annually [3]. Mill scale is suitable for direct recycling to the blast furnace via sintering plant [4]. Ap- proximately, 90% of mill scale .

Used for sintering (auxiliary material). Used in steelmaking (use directly or use as briquette). Used to make sponge iron ...

Sintering of iron ore is a generic term which is used to describe the process whereby a sinter mix (raw mix or green mix) of iron ore fines, fluxes, fuel (coke breeze) and plant return fines (e.g. mill scale, blast furnace dust, and returned sinter fines etc.) are converted into a particular form of agglomerate.

The invention relates to a method for the agglomeration of iron-oxide-containing residual materials, in particular scale and mill scale, wherein the residual materials and paper sludge are dried and ground and agglomerates are produced, by hot briquetting, from a mixture of the residual materials and paper sludge so processed. In this manner, it is possible to produce mill scale briquettes of ...

Before iron ore pellets became common, sintering was used to process fine ore so it could be fed into a blast furnace. This is stll being done overseas. Now, most sinter plants in the USA are the "garbage disposal" for the steel mill processing pellet fines, dust, and mill scale into blast furnace feed.

The sintering process begins with the preparation of a sinter mixture consisting of iron ore fines, fluxes, solid fuel (called bonding agents in Japan) such as coke breeze, and return fines from the sinter plant and blast furnace as well as recycled ferruginous materials .

A. Mill scale is oxides of iron and alloying elements present in steel. Obviously, it is a rich source of iron. Most of the steel plants recycle mill scale through sintering or pelletization. However, a value-added utilization of mill scale is in steel making after converting it into briquettes.

Mill scale is a byproduct that can be used for sintering iron and zinc ore. The scale is mixed with a fuel and an agglomeration agent is used to create the mixture. The sinter bed is then heated to bring the process to its conclusion.
