Performance
& References
- Finn
Inc.'s experience is proven by our past performance. The following are
some examples of Finn Inc.'s quality performance.
HOLCIM
INC.
Weirton Plant, WV
Cold
Runner (Large U-trough) used to transport molten slag that has just
been granulated,
Troughs / Launders |
into
a receiving hopper eventually into the dewatering system. The molten
slag is approximately 1,450°
F when it passes over the Blow Box or water injection system. This very
abrasive slurry impacts the cold runnern at extremely high velocity.
Earlier they used Hardox 400 wear plates in the cold runner. The whole
system now has our Ceramic (1") lining that holds up extremely
well. Hardox steel plates lasted only 3-6 months when our U-Trough sections
has not been replaced since the first was installed in June 2000.
Advanced Ceramic Tiles |
For
the rest of this slurry system almost all Pipes, Bends, Tees, Laterals,
Spools,
Reducers, Spray Bars and the Blow Box have our Ceramic products. Previously
most of these were Basalt Lined products.
Separator
in closed Circuit with Roller Mill for Granulated Slag. The Separator
has a 7ft high and 9ft ID cylindrical part and a 4 ft high (9 ft ID
at top) cone in the lower part. Finn Inc lined the cone on site with
3/4" thick castable Ceramic and for the cylindrical part we prefabbed
curved Tiles with anchors for welding to the steel cylinder frame. This
was done to reduce the down time. Since installation in March 1999,
very little wear is observed as of summer 2004.
