The blowing-in process is carried out in several steps (Fig 1) which consist of (i) drying out the lining, (ii) filling of the blast furnace with a specially arranged high coke blow-in furnace charge, (iii) igniting of the coke or lighting of the blast furnace, and (iv) gradually increasing the hot blast (wind rate) with frequent castings to ensure the raising of temperature of the blast

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 from downstream iron and steelmaking processes.

HOW A BLAST FURNACE WORKS Introduction The purpose of a blast furnace is to chemically reduce and physically convert iron oxides into liquid iron called "hot metal". The blast furnace is a huge, steel stack lined with refractory brick, where iron ore, coke and limestone are dumped into the top, and preheated air is blown into the bottom.

01.01.2010· Important properties of sinter for blast furnace process are reducibility, size and size distribution, cold and hot strength, and softening and melting behavior. Typical sinter suitable for blast furnace process is from 15 to 25 mm, as is illustrated in Figure 1.1.10 [22].Another important property is the disintegration of sinter in reduction, which occurs during the transformation of hematite

In the bottom part of the furnace, combustion air (blast) compacted by a blower is fed into the furnace shaft by nozzles (see Hot blast nozzle, Blast pressure). During this process, the counter flow principle is used to transfer heat from the combustion gases to the charge until it is melted (Figs. 1 and 2).

blast furnace process. The iron ore concentrate is now mixed and ready for the pelletizing process. Pelletizing A pellet plant contains a series of balling drums where the iron ore concentrate is formed into soft pellets, in much the same manner that one rolls a snowball, to make a pellet about the size of a marble (between 1/4" and 1/2").

Combustion process. The iron in the processed ores must be dissolved out by chemical processes. This requires an element that binds oxygen more strongly than iron. This is exactly what carbon can do as a reducing agent.The carbon is fed to the blast furnace in the form of coke (pyrolyzed coal) from the coking plant.At sufficiently high temperatures, the carbon can participate directly in the
