Retired, Dublin, OH 

For many years, involvement in melting and pouring of metals was my passion. Helping foundries succeed was always important for me. Being retired, I have appreciated the highs and lows of melting. I will highlight those highs and lows, while offering some key takeaways to benefit your foundry as well as cast a positive image on improving melt quality and safety. Metallurgists and Melters can be friends.

Fluorspar is a useful tool to aid desulfurization in a lime-based process. It also comes with significant restrictions when working with the melt parameters of Ductile Iron production. A synthetic option is available as an alternative to natural ore Fluorspar. This option can increase the envelope for effective usage and efficiency. Fluorine mechanisms and process effects will be discussed in pursuit of desulfurization optimization.

Foundry Manager, Ford Meter Box, Wabash, IN

Melting in channel furnaces offers many benefits and challenges. Outlining a path to improvement, Ford Meter Box has continued to work towards improving their furnace campaign lives by utilizing data and analysis. In the same vein, moving away from a manual pouring process to implementing a pressure pour unit, Ford Meter Box has learned lessons on what works and what has been an opportunity to improve.

Pig iron is a key raw material for the cast iron industry. Most pig iron consumed in the United States is in the form of Basic Pig Iron and is consumed in both integrated and electric arc furnace (EAF) steel mills. While integrated mills, by definition, produce their own pig iron via blast furnaces, EAF mills have traditionally relied upon imported pig iron. Today there are significant governmental, environmental and end user pressures to reduce material carbon footprints that are affecting both the steel and foundry markets.  In this talk, the speakers will discuss potential changes in iron feedstock and a back-to-the-basics discussion around trialing new materials in a process. The speakers will highlight: 
 

• The current and projected state of steel mills and how their raw material demands will impact the foundry industry.
• Impacts the changing mill requirements will have on the scrap stream as it relates to Carbon reduction goals.
• Direct Reduced Iron (DRI) and the impacts if it is used in an EAF, Cupola and/ or Induction Furnace.
• An alternative approach to producing pig iron by recycling byproducts and subprime feedstocks in a mini-blast furnace.
• Considerations when exploring various charge materials, specifically focusing on metal quality, recovery, and slag generation.

A panel presentation identifying process considerations for ductile iron treatment methods from foundries with different casting sizes and annual volumes. Panelists represent iron foundries with different primary melting methods including cupola, coreless induction, and channel induction. Treatment methods covered include sandwich method, Georg Fischer, modified tundish, and wire treatment.

This presentation will cover the key points of the installation of a new electric melt system, discussing the challenges of transitioning from a 120-year-old cupola foundry to an electric melt shop. We will also look at the learning curves of furnace linings, mixing alloys, melt efficiency, and safety.

The widely established cupola system design in europe differs in some technical and process related aspects to most of the cupola systems that are currently in service in US. Thus, a brief overview on the main differences between state of the art US and european cupola systems will be provided. 

The optimized process-internal hot blast generation in cupola systems is a key factor to increase thermal efficiency of cupola melting systems. Technical approaches to intensify this heat recovery process in order to gain hot blast temperatures up to 1.500 °F will be presented. 

The CO2-saving goals defined by the european legislative require a substitution of fossile coke by a CO2-neutral alternative in european cupola applications. One approach to achieve this is the use of biogenic, solid fuels, so called “Biobriks”. The general concept, the current development status of the product as well as gained practical experiences using this novel fuel will be presented.

Cadillac Castings Inc. experienced an unprecedented event in which a failure in the system caused their cupola to freeze. Several methods of removing the “slug” of metallics from the stack were attempted. His case study will cover the events leading up to the freezing of the cupola, how the “slug” of metallics was eventually removed, and lessons learned along the way.

Refractories are a necessary evil in melting operations. Today’s melt operations are lean and efficiency is critical. How can we do more with less? This panel will discuss experiences related to melting and holding furnaces and molten metal transfer equipment refractories. Lessons learned and best practices will be covered.

Brad Rudolph

The presentation will review the challenges associated with and lessons learned with melting secondary materials in copper channel furnaces. There will be a focus on lining materials and operational practices, along with a discussion of trials, testing and analysis performed.

Mark Kohler
Director of Induction Melting, Metal Technologies, Inc. (MTI), Auburn, IN

An overview of sound maintenance practices for coreless induction furnace systems and overcoming the challenges of less experience in the modern-day foundry. More then just the components of the system, the training of people and creating an internal knowledge base is vital to maintain and build productivity, reliability and safety in the foundry.
