I. APPLICATIONS:

SPRAYZUCAR 90 can be used in wet condition (during crushing) as well as in dry condition (on lathe of 3 to 5 RPM) or on stationery position.

II. DESCRIPTION:

SPRAYZUCAR 90 is the result of long research of the spray electrode for the crushing rollers of sugar mills. Roller arching with SPRAYZUCAR 90 process of surface treatment of mill rollers consists of the deposition of wear resistant cane gripping globular points or protrusion onto the sides and tips of the roll grooves on a three roll assembly.

SPRAYZUCAR 90 is a high alloy electrode designed to maintain a self regulating arc for the bonding of the hard metal globules to the cast iron rolls. In the presence of sucrose juice and can fiber dust. It deposits globular protrusions of high alloy complex martensite chromium carbide on the teeth of mill rollers. Increased frictional properties achieved by the globular deposits of SPRAYZUCAR 90 eliminates the need for chevrons resulting in the gain of 12% more surface area, more contact with the bagasse. The result is more pressure which leads to less humidity and a greater extraction.

BENEFITS:

More production, eliminate the need of chevrons, reduction in bagasse humidity and decrease wear on rolls.

WELDING PROPERTIES:

Powerful arc spray type which deposit cast alloy hot droplets of chromium carbide of high hardness. Perfect adherence and total utilization of the deposited droplets that are placed in ideal size, format and quality that do not detach in service.

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.
