Table 4.1.2　Iron Content and Agglomeration Rate of Charge Feedstock

Note:The"average iron content"in the above table excludes content of special ore.

Table 4.1.3　Quality Requirements for Sinter

Table 4.1.4　Quality Requirements for Pellet

Notes:1　The above table excludes special ore.
2　The basicity of pellet shall be determined properly in accordance with the burden mix of the blast furnace.It's necessary to make clear specification in the design document that the burdening of acid pellet and high-basicity sinter should be designed for achieving the pellet's physicochemical properties.
3　The basicity of pellet should not be valued in the range of 0.3-0.8.

Table 4.1.5　Quality Requirements for Lump Ore

Table 4.1.6　Requirements for Grain Size of Feedstock

Note:Grain size of the limestone，dolomite，fluorite，manganese minerals and silica shall be the same as that of lump ore.

Table 4.1.7　Quality Requirements for Top-charging Coke

Note:The quality requirements for stamp-charging coke are not listed herein because for stamp-charging coke oven，the coal batching varies greatly，coke products have pretty different densities，heat pattern is not complete as desired，and as a result，the technical indicators of the coke cannot fully meet the blast furnace production needs.
