Other Specification:

SUGAR ELECTRODE

I. APPLICATIONS:

The application of this electrode on sugar mill rollers improves the grip on the cane, increases the quantity of sugar cane crushed and, consequently, results in a higher sugar production.

SUGARHARD 90 has been developed to resist the extreme load produced during crushing. The deposit is highly abrasion-resistant and also corrosion-resistant.

II. DESCRIPTION:

SUGARHARD 90 has an aggressive “spray” type arc with excellent penetration to allow application while the mill is in operation.

By attaching the earth clamp to the gear box housing, arcing in the bearing area is avoided.

III. NOTES ON USAGE:

  • Hold electrode vertical to workpiece. Keep stable arc on moving roll for full spraying effect.

  • 2 o’clock position welds (45-50º angle, from the horizontal).

  • 12 o’clock position welds, Desired high spatter levels at high current.

All positions listed above, apply to procedures related to the surfacing/resurfacing of the crushing rolls for the sugar cane industry.
