Integrated iron and steel industries have many plants
that generate more than one industrial waste, especially in the
iron production unit. Whereas some of these industrial wastes
are used in the iron-making process, some of them are stored in
open areas. Blast Furnace Sludge (BFS) and Tar Decanter
Sludge (TDS) are good examples as a waste material which are
stored in the open areas. These materials cannot be used in iron
and steel production due to some restrictive reasons. Within the
scope of the evaluation of these two wastes at the same time, a
serial of tests was carried out in the Moving Wall Coking Test
Oven at Erdemir and Isdemir Coal and Coke Laboratories. In
these tests, single seam coking coals (low, medium and high
volatile) were milled to be 85% below 3, 15 mm and the BFS was
fixed at 0.5% and the TDS was added in certain percentages. The
results obtained from the coke produced in the Moving Wall
Coking Test Oven were interpreted by considering Coke
Strength after Reaction (CSR), Coke Reactivity Index (CRI),
stability and hardness values.
