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.

In order to determine the hot rolling processes, it is necessary to determine the temperature of Tnr. There
are many formulations to determine this temperature. These formulations vary according to the microalloys
found in the composition. Simulation equipments and methods are used in determination of temperature.
In this study, Tnr temperature determination of X70 quality Nb micro alloy steel material was performed by
using Gleeble 3500 thermal mechanical simulation device. Tnr temperatures found by formulations and
thermal mechanical simulation methods were compared and the closest formulation was tried to be
determined.
