Phosphate, rinse and borax systems for wire processing

The phosphate, rinse and borax system is designed to prepare heat treated wires for drawing. The applied phosphate creates a micro porous surface that assists in the lubricant ‘pick up’ as the wire passes through the borax tank.

Phosphate Tank
The phosphate tank is designed with corrosion resistant granite dipper rolls inserted into a stainless steel reservoir tank. The tank is heated to 90° C (194° F) by electric immersion heaters. A flow of solution counter to the wire direction is introduced by a fiberglass  pump.

The tank is angled towards its center point where a sludge pump is fitted. The entire tank is supported on a mild steel lrame with insulation on the sides and bottom to minimize heat loss.

Insulated covers are easily removed for the threading of wires.

Borax Tank
After passing through a heated water rinse, the wires enter into the borax tank.
The borax tank is fabricated oi reinforced fiberglass or stainless steel. it operates as a flood weir unit with a reservoir section and a processing tray.

Electric heaters control the temperature of the sodium borate solution to approximately 77° C (170° F).

Drain, fill and overflow connections are provided to suit your utility supply.
