INFLUENCE OF PROCESSING SPEED ON HIGH CARBON STEEL WIRE GALVANIZED WEIGHT AND MECHANICAL PROPERTIES

The zinc coating both increases the corrosion resistance and lubricated to minimize the friction for subsequent diameter reduction steps. The course of the reaction between the steel surface and the molten zinc depends upon the formation and growth of the iron-zinc alloy layers. The type and quantity of zinc coating layer produced depends on many factors particularly, immersion time, zinc temperature, steel wire composition, zinc composition and condition of the wire surface. PChange of the processing speed is an important factor as it will affect both the galvanizing time and the wiping of the coating. The as-fabricated galvanized steel wire needs to pass a number of quality tests before going on the market, concerning mechanical and corrosion properties. This paper presents data obtained from trials and production records on the effects of hot dip galvanising on wire properties. In this study, mechanical properties(tensile, elongation) and microstructure of alloy layer for different process speeds on wt. % 0.83 carbon wires at 3.20 mm diameter were investigated..
