WHO WE ARE

Sage was founded in 1978 in Brazil and operating in USA since 1985. It is dedicated to create alternatives for materials operating in particularly severe conditions. That includes high temperatures, chemically or mechanically aggressive conditions.

In 2010 Sage Thermal Shield was introduced to prevent the causes of unplanned outages in EAF mills.

Additional developments led to major opportunities to reduce production costs and ecological gains.

All these technological advances are described below.

Thermal Cracks

Tubes forming the panels in an EAF have their outer wall exposed to extremely high temperatures while inner wall remains cooled by water flow.

Every time power is turned off, huge temperature differences between inner and outer tube walls induce thermal cracks as shown at right.

No sudden cooling/heating occuers in Sage Panels, as shown below

Chemical Attack

Oxidizing atmospheres and high temperatures cause severe wear to the tubes material. During the primary refining, the environment between liquid bath, roof and shell tubes shifts from oxidizing to reducing atmospheres.

Both conditions impose corrosion on the walls causing leaks as shown at lower left.

Electric Arc Discharge

USING SAGE PANELS

Panels protected by Sage Thermal Shield® use proprietary materials and procedures that grant them much longer life cycles and also operating cycles that are at least 100% longer than traditional panels.

They are made available to users under a lease contract that includes maintenance and full-time technical assistance throughout the duration of the lease.

All components are made available in pairs to allow ready replacement at the end of each cycle. Used components are restored to their “as new” condition as soon as a cycle is completed.

Cycles are guaranteed to be longer and trouble free.

Additional gains granted by Sage Panels are:

The research required to make Sage thermal shield resistant to attack by foamy slag led to the development of Sage Self Foaming Slag.

The best material to resist attack by foamy slag was slag itself but pouring molten slag in between the fins proved to be impossible due to its instant solidification.

The research to overcome this problem led to the development of Sage Self Foaming Slag that eliminates most of the carbon required by the traditional foaming process.

Additional details are provided upon signature of a NDA with prospects interested in using this process.
