AUMUND Wins Order for Conveyor at New DRI Plant in Algeria
01/15/2016 - Germany’s AUMUND Fördertechnik GmbH is building a 116-meter conveyor that will link a new hot direct reduced iron plant to a meltshop at the Tosyali Holding AS mill in Algeria.
In a statement, AUMUND said it is supplying a patented pan conveyor with buckets at the mill, which is in the province of Oran. The conveyor will be capable of moving 323 tons hot DRI per hour at temperatures of 750 degrees Celsius.
“The improved sealing protects the material to be transported completely from any environmental influences. Thus, the inert system prevents the reoxidation of the highly reactive bulk material and makes the transport of the sponge iron possible without losing the high degree of metallization,” the company said.
AUMUND said the new DRI plant, being built by Midrex Technologies Inc. and partner Paul Wurth SA, will have an annual production capacity of 2.5 million tons. It will be capable of making both hot and cold DRI simultaneously.
AUMUND said the mill plans to feed the meltshop, which also is new, with hot DRI to save on energy costs and on wear in furnace electrodes.
“Compared to cold charging, the transport of HDRI results in up to 6 percent less wear on the electrodes. The tap-to-tap times get shorter, the demand for carbon as the primary energy carrier will be reduced, and CO2 emissions will be lowered as well,” said AUMUND Fördertechnik’s Frank Reddemann in a statement.
Because the DRI will be hot when put into the furnace, energy savings are expected to be above 120 kW per ton of liquid crude steel, the company said.
