Injection Technology for Energy Reduction)” ， which makes it possible to greatly

reduce CO2 emissions in the sintering process ， and successfully applied this

technology to a commercial sinter plant for the first time in the world.

In ordinary sintering process ， after coke breeze is mixed with iron ore and

limestone，raw materials are charged and sintered in sintering machine. To produce

high strength and high reducibility sintered ore，it is necessary to keep the sintering
ᇏݓࣁඋ࿐߶
temperature between 1-200 °C and 1-400 °C during sintering. In the temperature zone

below 1-200 °C， the strength of sintered ore decreases because raw materials don't ᇏݓࣁඋ࿐߶

melt enough. In the temperature zone over 1-400 °C， the strength and reducibility

decrease by increasing glassy silicate.

With “Super-SINTER ” technology，it is possible to extend the period in the
TM
optimum temperature by injecting a hydrogen-based gas fuel from the upper side of

the charged raw materials as a partial substitute for coke breeze. As the result， the

energy efficiency of the sintering process is greatly improved ， and it has been
ᇏݓࣁඋ࿐߶
achieved to reduce CO2 emissions.
