INTENDED USE

SYSTEM CONFIGURATION

The Descaling System consists of a 3-sheave Scale Breaker and a Cleaner/Precoater mounted on a common base plate. The Cleaner/Precoater includes a 60 gallon - 227 liter closed-loop, heated fluid system and a magnetic separator for continuously removing scale residues from the hot cleaning/coating solution.

SYSTEM OPERATION

In operation, the rod is pulled through the Scale Breaker by the wire drawing machine. Essentially all scale, on rod properly made for mechanical descaling with 0.5-0.75 wt % scale, is broken loose. And 80-90% of the loose scale falls from the rod and collects in the Scale Breaker cabinet. The remaining 10-20% is loose but clinging to the rod due to electrostatic charge. This undesirable scale residue is removed by the Cleaner/Coater which simultaneously coats the rod with any one of a variety of commercial precoat compounds. The rod is instantaneously dried on-the-fly.

The resulting rod is production clean, coated, dried and ready for drawing into wire.

SYSTEM CAPABILITY

Rod Composition - The WILCO Model 1060 is designed to mechanically descale low through high carbon hot-rolled steel rods.

Rod Sizes - The system is capable of processing rod sizes of 7/32 inch thru 1/2 inch - 5.5 mm 12.7 mm. The standard Model 1060 is equipped to process low thru high carbon rod .218 thru .266 inch - 5.5-6.75 mm diameter.

Rod Speed - Rod inlet speeds up to 850 fpm - 4.3 m/s can be descaled, cleaned, coated and thoroughly dried.

Rod Condition - The Model 1060 is uniquely capable of processing wet rod.

SYSTEM SPACE REQUIREMENT

The Model 1060 footprint is 76 inches long by 68 inches wide - 1.9 m by 1.7 m (footprint drawing available).
