The new briquetting technology for blast-furnace smelting has recently come back into use. An industrial line for brex production with a design productivity of 20 tons/h was introduced in April 2011 at a small metallurgical plant owned by the company Suraj Products Ltd. in Rourkela (India). The plant makes foundry iron and conversion pig iron ...

In this paper, bed agglomeration characteristics during the combustion of biomass fuels using a relatively new bed material (iron blast-furnace slag) as well as ordinary quartz sand were determined. Controlled agglomeration tests lasting 40 h, using five representative biomass fuels (bark, olive residue, peat, straw, and reed canary grass) were ...

Effect of distribution of iron concentrates between pelletized and matrix feed on the preparation of blast furnace burdens from two different kinds of fine iron concentrates (magnetite and hematite) by composite agglomeration process (CAP) was explored. It was found that when the mass ratio of iron concentrate A (magnetite) to iron …

Abstract. An innovative process of preparing ironmaking burden – the composite agglomeration process (CAP) has been developed. In CAP, part or all of the fine grained iron bearing materials are separately made into 8–16 mm diameter green pellets in a balling disc or drum, and the rest of fine grained and all of the coarse grained …

There is a significant and necessary drive towards reducing CO 2 emissions produced by iron and steelmaking industries. Binding Solutions Ltd has developed a technology to contribute to the reduction of CO 2 in the short and long term, by introducing a cold-bonded iron ore pellet to the furnace burden. Binding Solutions' cold-agglomerated …

Blast furnace iron manufacturers aim to reduce expensive coke usage through the injection of coal. This paper investigates contrasting agglomeration behaviour with a view …

The stability of blast furnace process depends upon the quality of raw materials charged into the furnace. Among iron-bearing materials, pellets are an important feed material for the blast furnace operation. ...

The history of the agglomeration of iron-bearing raw materials for blast furnaces dates back to the first commercially successful such undertaking – the Grondal project. That project involved the production of briquettes from fine magnetite ore and was carried out in Finland in 1899 [1].

The blast furnace slag is obtained from Iskenderun Cement Industry. During the production of both artificial aggregates and concretes, a CEM I 42.5 Portland cement was used as a binder. The physical and chemical properties of fly ash, blast furnace slag and cement are presented in Table 1. The properties of fly ash-B are similar to those of …

As a promising method to strengthen the blast furnace smelting and to realize reduced fuel operation, high-proportion pellet charging has become the practice of BF ironmaking. Use of pellet gives rise to uniform bed permeability in comparison with iron ore or sinter. This leads to better gas–solid contact resulting in higher productivity at …

Software for calculation of metallurgical parameters and costs of iron production in blast furnaces, including calculation of agglomeration parameters. Allso: optimization of burden (at minimum cost or maximum productivity); calculation of minimum possible and actual …

There are several agglomeration processes including: briquetting, extrusion, nodulization, pelletizing and sintering, …

Composite agglomeration is a sintering technology in which a pelletized feed and sintering matrix feed are intensively mixed to produce high-quality charges for the blast furnace. 43 During the ...

There are several agglomeration processes including: briquetting, extrusion, nodulization, pelletizing and sintering, although pelletizing and sintering are the most widely used, and …

and agglomeration of the mix. On the underside of the sinter strand is a series of windboxes that draw combusted air down through the material bed into a common duct, leading to a gas cleaning device. ... Hot metal from the blast furnace is added by pouring from a ladle through a trough positioned in the door. The mixture of scrap and hot metal ...
