Figure 5 Process flow through No.5 Blast Furnace 5.4.2 Blast Furnace The Blast Furnace is a vertical shaft of circular cross-section and stands approximately 40 m high (although the overall facility approaches 100 m). The vessel is internally lined with cooling elements and refractory bricks and blocks.
به خواندن ادامه دهیدProcess Description. R&D Trends. Blast furnaces are usually tall shaft-type steel vessels, up to ten stories high, internally lined with refractory brick, and superimposed over a crucible-like hearth. The necessary charge to produce molten pig iron consists of iron-bearing materials, coke, and flux. The charge is introduced into the furnace at ...

The Kakogawa #1 blast furnace, which led the way, was one of the first furnaces domestically to install a movable armor and the first domestically to install an in-furnace gas sampler, which served
به خواندن ادامه دهیدBlast Furnace Process. The blast furnace is a counter-current gas/solids reactor in which the descending column of burden materials [coke, iron ore and fluxes/additives] reacts with the ascending hot gases. The process is continuous with raw materials being regularly charged to the top of the furnace and molten iron and slag being tapped from ...
به خواندن ادامه دهید3. PROCESS In the Blast Furnaces (BF) liquid iron (popularly termed as 'Hot Metal') is produced by the process of reduction at high temperature from raw materials like iron ore, base mix, sinter, coke, fluxes (limestone / quartzite), etc. &also air blast / O2. In blast furnace the process is also known as
به خواندن ادامه دهیدBlast furnaces are used continuously and are only shut down when their brick lining needs replacing. As the mixture of iron ore, coke and limestone heats, the hot waste gases are collected and cleansed. They are then used to help heat the air blast, required if blast furnace is to reach the high temperatures needed to produce molten iron.
