Blast Furnace Reline project and it is possible that it will not go ahead. However if it does go ahead, it will be done in conjunction with the Blast Furnace reline project. Therefore, BlueScope Steel seeks DGR's for the following alternatives: a) DGR's for the Blast Furnace Reline project and the Sinter Plant Project (Project 1); and

coke breeze is used as a bonding agent for sinter, and lump coke is charged to the blast furnace. The coke oven gas (C gas) and blast furnace gas (B gas) generated by the coke ovens and blast furnace are used as fuels in various ironmaking processes (sintering, coke ovens, hot stove, power plant), or are injected into the blast furnace
Abstract: Through analyzing and inspecting the raw materials conditions and process conditions that affect ferrous material reduction in the thermal reserve zone, the article indicates that for the three commonly used ferrous material of blast furnace, sinter, pellets and lump ore, sinter is easiest to reduce and lump ore is most difficult to ...
as a part of the charge mix during sintering of iron ore fines. It has been reported that several sinter plants in the world recycle2, 3 up to 180200 kg of waste oxides per ton of sinter, whereas in India this rate is slightly lower, at 100170 kg per ton of sinter1. Some iron oxide wastes, like LD .
about the use of lump ores in modern BFs, and indicate the technical direction for using lump ores. Keywords: Lump ore, Sinter, Interaction, Softening properties, Blast furnace, Blast burden Introduction The ferrous burden materials used in Chinese blast furnace (BF) are high basicity sinters, acid pellets and natural lump ores.
SINTERING PLANT. COKE BREEZE SIZE •The required coke breeze granulometry for efficient sintering is: +5 mm < 5 % . • For reducing the microfines generation during mm = 8590 % 0. 57 .5 mm < 15 % •Presence of higher % of +5 mm slows down the .
Blast Furnace (pig iron) – Blast furnace (Figure 2) is a process for producing liquid raw iron by smelting pellets or sinter in a reducing environment. The end products are usually molten metal, slag and blast furnace gas. In the reduction process, oxygen (O 2) is taken out of the pellets or sinter. Coke is often used as a reducing agent, as well
In addition to producing feedstock for its own blast furnaces, the mill also supplies a leading Indian steelmaker with extruded briquettes, which is charging between 35% in a highvolume furnace. Result: The homogenous blend of iron oxide fines and fine carbon particles have driven a .
iron ore pellets versus sinter in blast furnace. Blast Furnace Ironmaking Process Using Prereduced Iron Ore197 Кб. Fine ore is a raw material for sinter that is the main component of the blast furnace fluidized bed is used when reducing fine iron ore directly57), whereas a shaft furnace is used when reducing lump ore or pellets.
The sinter of high basicity would interact with lump ores or acid pellets in the cohesive zone of blast furnace due to the difference of chemical composition and micro structures. The results of this work showed that the softeningmelting properties of lump ores and acid pellet would be obviously improved by the high temperature interaction.
In traditional blast furnace iron making, the iron ore is fed to the blast furnace in one of three common forms: Lump, pellets or sinter All of which are designed . 【More】 iron ore pellet 2 blast furnace .
Profitability Solutions: Using sinter in place of lump ore and pellets helps to reduce blast furnace fuel rate and CO 2 emissions.. Adding fluxed sinter feed to the blast furnace increases softening and melting temperature and improves reduction. Contact Supplier
Sinter plant practice and the control of the sulfur content of sinter 70 Eliminating sulfur from the blast furnace as SO 2 74 10. Implications for Process Modelling 79 Blast rate and productivity prediction 81 Defining reaction outcomes in the furnace shaft 83 Melting rate control 85 .
Literature review reveal that formation of a narrow cohesive zone lower down the blast furnace improves the productivity and reduces the coke rate and that in majority of the cases, the iron bearing material in the blast furnace reaches the softening temperature (top end of cohesive zone) with a reduction degree higher than 50 percent. The lowering and narrowing of the
The Blast Furnace charge mix will be combination of high percentage Sinter Pellet and balance lump ore. The BF will have modern features like high top pressure, stave cooling, carbon lining etc. The BFs will be provided with PCI system at a rate of 160 Kg/thm..
