Sinter Plant

benefits and technical suitability for BF operations. As on today, sinter has become widely accepted and preferred burden material in blast furnaces. Almost, there is no blast furnace operating without sinter, nowadays. The sintering technology was developed for the treatment of the waste fines of iron ore, coke, line.

How we make steel | British Steel

Additional raw materials are processed at Scunthorpe's sinter plant, which forms an iron-rich feedstock for the blast furnaces. The ingredients – iron ore, coke and line fines – are carefully stacked and blended, then passed under an ignition hood at the sinter plant. This heating process is carefully controlled to make.

Blast furnace - Wikipedia

A blast furnace is a type of metallurgical furnace used for smelting to produce industrial metals and its alloys, generally iron, but also others such as lead or copper. In a blast furnace fuel (coke), ores, and flux (line) are continuously supplied through the top of the furnace, while a hot blast of air (sometimes with oxygen.

Simplifed Steel Making Tutorial: Iron Ore to Iron

Now the sintered iron ore is prepared to be heated to a very-very high temperature where the ore melts in the presence of gases. . the O3 (oxygen) in the Fe2O3 laden ore by adding a great amount of heat in the presences of coke, which is a pure form of carbon (C), and line (CaCO3) principally calcium carbonate.

Agglomeration behaviour of steel plants solid waste and its effect on .

The amount of coke breeze and iron ore was fixed to 300 g and 3 kg respectively, whereas the other raw material mixes are calculated for aforesaid basicity of sinter. The sinters produced in experiments have been graded as S1, S2, S3, …, S15 by varying line fines, i.e. flux and the amount of waste made pellets which.
