Glasstrend Bilbao “Recent improvements in electrical glass furnace boosting systems”

There are several methods of applying electrical energy to a furnace, like multi tap switched or slide wire
controlled transformers, both having their specific advantages and disadvantages. Another
method makes use of SCR’s (silicon controlled rectifier) or what we call thyristors, to control the
power.SCR controlled boosting system are considered to be the latest, solid state technology although
the principal exist for more than 50 years (proposed by William Shockley in 1955). We have to
understand that the SCR is in fact only a solid state current switching device. The trick behind those
SCR’s is of course the complicated and sophisticated algorithms controlling the SCRs which became
available after the introduction of the ultra-fast micro and digital signal processors
Having this technology available, we are now capable of controlling SCRs such that they are capable of
adapting to all kind of situations and running these applications at the highest efficiency and best power
factors possible. Based on this technology and with the availability of a new transformer design we took
the opportunity to rework the total boosting layout aiming for at least 10% of electrical power efficiency
improvement and a standard design that should be able to fit 90% of the customers’ requests. This paper
will explain the basics of Ohm’s and Maxwell’s laws, show what need to be considered during the design
stage and how efficiency improvements can be found. Finally yet importantly, the paper will explain how
a “one size fits all” approach on a furnace boosting system could result in a standardized design for
multiple sites and furnaces.

It is a capital mistake to theorise before one has data

Obviously, the title of this new Glass WorldWide article was compelling enough to draw attention. Readers may be sufficiently convinced that glass melting and forming processes are some of the most complex manufacturing methods known in industry but, in my opinion important improvements can be made.

Glasspex India great success

20150313_Glasspex_India 093

This year, Eurotherm by Schneider-Electric participated again the Mumbai India Glasspex trade show. The quality of the show has increased potentially and reflects very well the growth and developing of India. Many high level people came to our booth and we had many interesting discussion and ideas exchanges. We would like to thank all that came and visit us and Messe-Duesseldorf for their great support and hospitality. See you all, and hopefully many more in two years.

Glasstec 2014 great success!

20141021_Glasstec 017

Glasstec 2014 has been a great success for Eurotherm by Schneider-Electric. Many people came, visited us, and shared their ideas and projects with our multinational booth team. We tried to capture as much as possible in visit reports and we will try to follow up all leads as soon as possible now. We would like to thank all that came and hope to see you soon at your facility to continue our discussion. Perhaps we will see each other next week already at the Glass Problems Conference.

Eurotherm E+PLC Launch at Furnaces North America (FNA2014)

It’s tradeshow season!! Eurotherm launches the E+PLC at Furnaces North America (FNA2014) – watch the interview below between Reed Miller (Industrial Heating Editor) and Peter Sherwin (Eurotherm).

Cost of Heat Treat quality compliance $780,000 per year …and FNA2014

Tom Morrison (CEO, MTI – Metal Treating Institute) recently introduced a video about “The Keys to Connecting Specifications and Audit Performance” and spoke about the high potential costs of quality compliance in Heat Treat operations – potentially as much as 13% of a Heat Treaters gross sales. Using the average MTI Heat Treaters Sales revenue, this could be as much as $780,000 per year – a significant expense!

Tom interviewed Jim Oakes and Andrew Bassett to get their views on conforming to Heat Treat standards and asked them about two or three keys to help Heat Treaters improve compliance to the standards.

1. Good understanding of the standards. Don’t take shortcuts! Get outside help if needed.

2. Well documented Control plan to deal with situations when you have a deviation.

3. Good training (mainly due to experience retiring from Industry).

For more information, please click on the image below to watch the original video.

mti videoEurotherm will be exhibiting at FNA 2014 Oct 7-8 (next week!). Please spend 5 minutes with us at booth #414/416 so we can show you some methods using existing and/or new technology to help you reduce this high cost of quality compliance.

The Future of Heat Treatment (reply to Janusz)


I just read an interesting post on Linkedin from Janusz Kowalewski regarding the Future of Heat Treatment and have already shared my response on both Linkedin and Facebook. I have copied the reply in detail below.

Please refer to the post from Janusz for background information.

It’s been fascinating to watch and be part of the developments in Heat Treatment over the past 25 years (migrating from a so-called Black Art to a Science) and know that the best is yet to come.

I think current decisions around material type and selection, processing options and the overall production cell configuration are more complex given the broad selection of Heat Treat and related processes on offer. The route taken today may or may not be the optimum route for your processing needs tomorrow – furnaces need to be able to offer a level of flexibility just in case a process change is required throughout the furnaces relatively long life.

Today’s control systems do offer a level of flexibility that allows for process improvements and/or changes to be made relatively easily, this was not possible in older systems.

Reference the point about the link between the Control Layer and Production Software for greater efficiency; I am part way through a new book by Peter Martin and Walt Boyes about “Real-Time Control of the Industrial Enterprise” – this describes in detail how control systems link to the enterprise and how this potentially impacts profitability. Full disclosure; Peter is a colleague at Schneider Electric (formerly Invensys).

The last point made by Janusz centered on furnace control systems and automatic reasoning, this is a really interesting topic. In the past the hardware and software technology available and complexity of programming has dictated what is commercially possible, we are about to challenge this situation.

Over the past two years we have been developing a new PLC and will launch the Heat Treat version of this PLC at the upcoming FNA show in the US  The major development in this technology is that we have been able to build on the widely supported open PLC platform technology of CODESYS and have embedded unique Functions that start to enable solutions relating to predictive/reasoning technology at a commercially acceptable price.

I do think this ‘type’ of technology will start to change what’s possible in Heat Treat control.

Hope to see many of you at FNA2014 in early October.
