Belzona® Keeps Metal Churning

 
 

Industry:

General Industry (GIND)

 
 

Application:

Gaskets, Seals and Shims (GSS)

 
 

Customer Location:

Metals Plant, North Carolina, USA

 
 

Application Date:

February, 2008

 
 

Application Situation:

Magnetic Cylinder, called a Stirring Jacket, used to mix molten Titanium.

 
 

Problem:

Electrical shorts in the coil wrapped around the cylinder caused a loss of current responsible for producing the magnetic field used to stir the molten titanium.

 
 

Products:

Belzona® 2221 (MP-Fluid Elastomer)

 

Substrate:

Stainless Steel

 
 

Application Method:

Application was carried out in accordance with Belzona Know-How System Leaflet GSS-1. Approximately one mile of #6 wire which supplied the current was removed. After surface preparation, one coat of Belzona® 2221 was applied, the coil was then re-wrapped, and a further coat of Belzona® 2221 was applied over the coil.

 
 

Belzona Facts:

The metals plant was not able to isolate the electrical short. It was more cost effective to insulate the jacket rather than to replace the coil. This job was done two years ago and remains in service. The plant was extremely happy to begin production again in such a timely manner.
