Pattern Facility
EEC uses wood, laminate & foam patterns that are typically
sourced from outside pattern shops. EEC performs
regular pattern maintenance & constructs custom blocks
for truck, rail & container shipments.

Mold Production
Sand system - 1 Walco and 1 Didion are supported by a total of 7
continuous mixers, which in total are capable of mixing &
discharging sand at a rate of 300 - 2000 lbs (136 - 909 kg) per minute.
Our on-site sand reclamation system, which can process up to 90% of
reclaim sand guarantees that sand is conditioned to ensure optimal
properties when blended. Chemically bonded sand molds (Furan).
Pit Molding - Up to 20' ( 6.1 M ) wide x 133' (40.5 M) long x 6'
(1.8 M) deep and 6.4 M (21') wide x 87' (26.5 M) long x 8'
(2.4 M) deep

Steelworks Practices

Ingot Mold Temperature at start of cast (~100°C is ideal)


Ingot Mold cooling after use


Adequate space for uniform heat dissipation
Handling


Slow cool in air
Ingot Mold spacing for teeming


Preheat when cold
Avoid rough handling during stripping
Internal Surface Conditioning Program

Remove oxidized layer and shallow cracks
Foundry Processes

Chemistry Control
Effects of C, Si, Mn, S, Ti
 Deleterious effects of Pb, Cr, P


Solidification Control
Inoculation
 Teeming
 “Shakeout” time

Effects of Elements in Gray Iron



Carbon and Silicon (C.E.)
 Increases graphite volume and coarseness
 Reduces Tensile Strength
Manganese and Sulfur
 MnS promotes graphite nucleation
 Refine graphite
 Promote Pearlite
Titanium
 Refines graphite
 Increases ferrite
Deleterious Elements



Lead
 Produces abnormal graphite (spiky, mesh, Widmanstätten)
Chromium
 Causes shorter, thinner graphite flakes
 Can form large carbide particles
Phosphorus
 Can form FeP eutectic phase
Foundry Practices

Inoculation

Gating and Pouring

“Shakeout” time
Foundry Practices

Inoculation - Control of solidification by the addition of
FeSi, Al, Ca, etc. in the iron prior to pouring



Promotes small, uniform “Type A” graphite flakes by providing
nucleation sites
Prevents under cooling and “chill” (formation of primary carbides)
“Shakeout” Practice - removal of the cast iron mold
from the molding sand


Cooling rate after solidification is critical factor in obtaining optimum
microstructure and resultant mold life
Premature “shakeout” produces a fast post-solidification cooling rate



High residual stresses
Excessive pearlite in the microstructure
Poor mechanical Properties
Summary


Large ingot molds are exposed to severe temperature gradients
and stresses
Optimum mold life can be achieved with:
 Selection of the cast iron (gray or ductile)
 Mold Design (wall thickness, corner radii, etc.)
 Steelworks Practices (preheating, cooling, spacing,
handling, conditioning)
 Foundry Practices (chemistry control, inoculation,
gating/pouring, shakeout control)
