| Decalub has introduced the new dry high-performance steel rod cleaning and preparation system (DCCD process , enabling in-line direct drawing of mechanically descaled high-carbon rod (from 0.78 to 0.88 per cent C), without wet pre-coating chemicals and without rod speed limitation.
This new system permits a direct drawing from the green rod, at unlimited rod entry speed - does not need any acid and completely eliminates phosphate, borax and other wet pre-coatings. According to users, this system provides one of the greatest performances ever obtained in mechanically descaled rod surface preparation.
The system excels in the most demanding applications and offers immediate substantial cost savings in production of quality wires, including spring, rope, bead, PC strand, galvanised H/C or L/C, CO2 welding, plating quality and collated nail.
The Decalub DCCD process incorporates the new LVC/PDH rod coating technology that enables an automatically controlled fusion of lubrication compounds, or their blends in all proportions, independently of their melting properties and grain size. Such a "liquefied" substance achieves an exceptionally consistent and hard residual coat, adjustable in weight, at all speeds.
The DCCD processed 5.5 mm (0.218") 0.83 per cent C rod is dry coated and drawn directly, in-line, without wet pre-coating, to 1.85 mm (0.073") at 13.5 m/s (2700 ft/min) with virtually "zero friction" - exiting wire temperature not exceeding 45 �C (113 �F).
