Clean galvanising solutions

MHD (magneto-hydro-dynamic) galv- anising technology is claimed to be the only eco-friendly galvanising process on the market today. SunWyre offers economical and environmentally friendly galvanising solutions for rod, wire, rebar, pipe and tubing. SunWyre’s modern process is for high or low carbon steel wire rods or wire, 4 to 16mm diameter, moving at speeds from 1.7 to 5m/sec automatically and continuously through galvanising and drawing, non-stop. The skilful integration of continuous rod pay-off, blast cleaning, induction heating, MHD galvanising, quenching, wire drawing and coiling or spooling, all managed by touch-screen PC, provides an efficient continuous process for galvanised wire manufacturing. SunWyre’s proprietary MHD process offers the following advantages: • It is energy efficient • Energy costs to maintain only one ton of zinc, instead of 50 or more, are lower than traditional wire galvanising • 7kW or less will maintain the pot temperature when the system is idle • Non-polluting • Uses no acid or flux • Requires no waste water treatment system • Emits no toxic fumes • Creates no hazardous by-products • Offers lower operating costs than traditional hot dip galvanising • Fewer man-hours are required to operate the process • Low nitrogen consumption compared to conventional gas wipe methods The SunWyre MHD process offers an innovative approach to the production of galvanised and galfanised steel wire.
