Effect of Drying Temperature on the Performance of Graphite Emulsion for Cold Drawing of Wire-Cut Molybdenum Wire
This study investigates the influence of different drying temperatures on the thickness,carbon and oxygen content variations of graphite emulsion coatings prepared on molybdenum wire surfaces and their impact on the lu-brication effectiveness(die wear level and molybdenum wire surface quality)during cold drawing processes.The re-search methodology involved employing three interpolated drying temperatures(600,700,800℃)for hot extru-sion of molybdenum wire,followed by individual application of graphite emulsion drying to obtain the respective graphite emulsion coatings.Subsequent comparative testing was performed after cold drawing opera-tions.Experimental results reveal that varying drying temperatures lead to changes in the thickness of the graphite e-mulsion coating and its carbon-oxygen content,consequently influencing the lubrication performance of the graphite and subsequently affecting the lubrication effect during the subsequent cold drawing of molybdenum wire.Among the three drying temperature points,at 700℃,the graphite emulsion coating exhibited maximum thickness,with a proportionate and moderate carbon-oxygen content ratio,significantly enhancing the lubrication performance of the graphite.Therefore,the conclusion drawn is that at a drying temperature of 700℃,the prepared graphite emulsion coating demonstrates improved lubrication effects during subsequent cold drawing of molybdenum wire,resulting in lower die wear levels and better surface quality of the finished wire material.This research provides valuable insights for optimizing the lubrication effects in the cold drawing process of molybdenum wire for wire cutting applications.
