ANOTEC - High Silicon Cast Iron Stick Anodes
Chill Cast in Metal Molds: Assures consistent weight, greater density, less flake graphite grain boundary, and lower chemical segregation than Sand Cast Anodes. The ANOTEC Chill Cast structure is similar to "Spin Cast" Tubular Anodes.
More than Twice as Strong
Independent laboratory tests confirm that Anotec Anodes withstand drop impact tests to more than twice the height of Sand Cast Anodes.
Quality Control
Chemistry, weight, impact strength and connection cavity integrity verified for each production lot in accordance with "Specification for High Silicon Chrome Stick Anodes" available from Anotec.
Performance
Accelerated Corrosion Tests confirm that Anotec Chill Cast anodes perform significantly better (up to 19%) than Sand Cast anodes in chloride and sulfate environments. Test reports available on request.
Spherical Tip
Prevents hang-up when lowering into deep wells.
Typical ANOTEC Anode Cross Section
A dense skin of minute columnar grains and a dense core of equiaxial grains. Occasionally, very fine interdendritic porosity at center. Predominantly spheroidal shaped graphite. Similar to the structure of vacuum refined High Silicon Iron.
Typical Cross Section of a Conventional Sand Cast Anode
Skin of nonporous equiaxial grains. Remaining section relatively porous from interdendritic shrinkage and porosity. Predominantly flake graphite with larger boundary areas than equivalent spheroidal graphite.
