| Abstract | ||
| Dry solid lubricant for steel wire drawing was prepared and improved from locally available raw materials for the benefit of Al-Hilal Welding Wire Factory/South of Baghdad. Due to the unavailability of international specifications for such lubricants, small proposed batches of 5.0 kilogram were tested each time in 5.0 mm steel wire drawing, and the observations on its performance were recorded. The reports of the performance of every designed batch were obtained and examined, then improved. After many trails in the actual production line of the factory by tuning the lubricant constituents, their proportions, and physical composition, the convenient performance was achieved. The convenient particle size distribution of the lubricant was studied, and monitored to get efficient application of the lubricant particulates around the wire surface, and found to be within certain limits (mesh size rang of 20-100) for the recommended wire specification. The product performance was compared to that of the imported lubricant, of German origin, and found to be identical; the above factory was supplied with its operational requirements of this lubricant. The work includes, as well a synthetic method useful for large scale production of calcium stearate, the essential component of the steel wire drawing lubricant, from industrial grade soap lump, calcium carbonate, and hydrochloric acid. | ||
