Sintered Ore Philippine Sinter Corporation

Sintering of iron ore is a pre-process vital to steel manufacturing. It begins with the mixing of fine iron ore, solid fuel such as coke breeze & anthracite coal, and flux such as limestone & dolomite. Sintered Iron Ore/ Sintered Ore (SO) is the result of the sintering process. The product is made of ferrous and calcium which can be produced

Limestone Its Processing and Application in Iron and

Jul 07, 2017· Application of limestone and lime in iron and steel plant. During the production of iron by blast furnace (BF) route, limestone is added either in the process of sintering or as a direct feed in the blast furnace. Limestone is normally added during ironmaking for obtaining either neutral or

The chemistry of steelmaking. Making iron.

In this condition, the ore is difficult to handle without creating dust that can be wasteful and polluting. Heating a mixture of this loose material with fine coke from the ovens makes a much coarser material called sinter. Sinter is fed into the top of the Blast Furnace as well as coarse lumps of coke, limestone and iron ore.

Ore Sintering an overview ScienceDirect Topics

Apr 02, 2010· Like other sintering processes, iron ore sintering converts iron ore fines of often − 8 mm sizing into larger agglomerates, namely, sinter, between 5 and 50 mm particle size, which possess the physical and metallurgical characteristics and gas permeability required for efficient blast furnace operation. As shown in Figure 14.1, iron ore sintering is carried out in three stages: raw material
