#207 - Tenova Goodfellow to optimize twin shell EAFs at Steel Dynamics Inc.

Mississauga, 17 February 2015: Tenova Goodfellow receives PO for two (2) EFSOP holistic optimization® systems including water detection for both twin shell EAFs at Steel Dynamics Inc. Butler, IN.

In Post #205, we discussed the basic operation of an electric arc furnace (EAF). One of type EAF is known as ‘twin shell’. From Wikipedia:

The scrap basket is then taken to the melt shop, the roof is swung off the furnace, and the furnace is charged with scrap from the basket. Charging is one of the more dangerous operations for the EAF operators…In some twin-shell furnaces, the scrap is charged into the second shell while the first is being melted down, and pre-heated with off-gas from the active shell…After charging, the roof is swung back over the furnace and meltdown commences. The electrodes are lowered onto the scrap, an arc is struck and the electrodes are then set to bore into the layer of shred at the top of the furnace. Lower voltages are selected for this first part of the operation to protect the roof and walls from excessive heat and damage from the arcs. Once the electrodes have reached the heavy melt at the base of the furnace and the arcs are shielded by the scrap, the voltage can be increased and the electrodes raised slightly, lengthening the arcs and increasing power to the melt. This enables a molten pool to form more rapidly, reducing tap-to-tap times.

Tenova Goodfellow has significant expertise in making this and other types of EAF operate more efficiently and effectively.

Steel Dynamics Inc., has confirmed an order with Tenova Goodfellow for the supply and purchase of two (2) EFSOP holistic optimization® systems for both EAF batteries at their SDI, Butler, IN steelmaking facility. Tenova’s innovative technology and value proposition will provide full spectrum evaluation via upstream and downstream offgas analysis and water detection technology for all 4 EAF shells. The scope of supply will also include newly developed optical sensors for the measuring of off-gas velocity and temperature.

The order which was received in December 2014, included project work that was scheduled to begin immediately with the manufacturing of hardware & sensors at TGI’s Hamilton, ON production facility, Nova Analytical Systems. Installation and commissioning of the systems is scheduled to take place by April 2015.

#206 - Heart and Soul takes over 270 Sherman

We saw this article about the arts side of our facility in today’s paper:

Arts and wellness festival beginning of ‘larger conversation’ about living sustainably
The Cotton Factory, an artist loft complex at 270 Sherman Ave. N., is like a city unto itself, several converted factory buildings teeming with art studios, workshops and businesses big and small. This weekend, its largest room — the size of a small arena — will hold a city of its own, as two-day arts and wellness festival Heart and Soul takes over.
"I see this as a park or a city block and we'll build a little city in this block," explained Annette Paiement, the event's founder, as she walked through the cavernous space, pointing out which sections would have vendor booths and which would have workshops.
Her vision is for an outdoor festival, but inside — a break from the solitude that comes with winter. The room is certainly big enough.
"I'm asking people to bring their lawn chairs and blankets."
The event starts each day with 11 a.m. yoga, followed by a suite of workshops, talks and performances. Session titles include Mindfulness: Coping with Stress; Heartbeats and Native Storytelling; Elysium Tribal Dance Presentation; and Sustainable Food and You. Admission to the event is free, but some of the workshops charge a fee.

"A lot of people will be set up to do mini-massages or other mini-treatments," she added. 
The event serves as a launch for the Centre for Artistic Sustainable Lifestyles, a co-working space being built in the west end of the massive room. Paiement is CASL's executive director and envisions a communal office for people working in alternative wellness, non-profit ventures and the arts.
"Heart and Soul is like a soft launch for the kinds of things we want taking place at CASL year round," she said.
Paiement also plans to expand the event to other cities. She sees the event — and the co-working space — as ways to bring people together to change the world.
"I think about sustainability and the state of the world right now, and we are at a crossroads," she said. "The only thing that is going to save us is each person on an individual level being responsible for themselves. Looking at how they do everything: how they shop, how they cook, how they make money.
"It all has to inform the larger conversation."

A lot more goes on here than just analytical technology.
