Tenova HYL Strikes Up Partnership with Mill Byproducts Recycler
01/04/2017 - Tenova HYL and Diproinduca Canada Ltd. have formed an alliance that will further develop and commercialize technology designed to reuse iron ore fines in direct reduction plants.
“In the current struggling steel market scenario, in which each dollar counts, this exciting technology will provide (direct reduction) plant users a technology for reducing byproducts, increasing the yield and ultimately optimizing their operating costs, which obviously is the target of steelmakers anywhere,” said Tenova HYL commercial director Pablo Duarte in a statement.
Tenova said the technology it and Diproinduca Canada are working on captures fines from a variety of sources -- material handling scrubbing systems, iron ore screenings and the sludge from the scrubbing systems tied to reduction and cooling gas circuits -- and turn it into a feedstock.
The feedstock, in the form of a briquette, is meant to be fed directly into the reducing reactor to produce DRI, thereby increasing yields and lowering operating costs by eliminating the logistics associated with fines disposal.
Tenova said its direct reduction briquettes technology has been developed over the past two years at Ternium’s 3M5 plant in Monterrey, Mexico.
“Tests results have shown an average metalization of 94% to 95% with carbon content of about 3% and low fines generation, all at the same level of the DRI actually produced from iron ore pellets, reflecting the excellent behavior of the briquettes in terms of porosity and mechanical strength during the reduction process inside the industrial reactor,” the company said.
