Raw material granulation and sintering

Granulation of raw materials is the single most important factor in controlling the permeability of the sinter bed and hence the productivity of the sinter line. Treatment of the binding water in a magnetic field reduced its surface tension enabling better binding of the small fraction size…

Doubling the life of torpedo ladles

The selection of refractory lining design and installation of targeted high-wear areas of torpedo ladle lining using innovative techniques have doubled the life of torpedo ladles to 2,500 cycles equating to the transport of 775kt hot metal per ladle before relining. This is the first step…

Models for EAF energy efficiency

The EAF process is the subject of continuous cost and process improvements and energy models help to benchmark a particular EAF process by accounting for variations in production parameters, such as deviations in raw materials quality and process parameters such as metal yield, oxygen…
