A Hungarian customer had historically used aluminium wire drawing lubricant Alumol™ 145 for drawing a mixture of pure and alloy aluminium rod at 25-30 m/sec on Henrich rod breakdown machines with 4000L tanks. The customer had decided to trial a locally sourced alternative lubricant at the same time as a new fill of Alumol™ 145.
The comparison between the two tanks revealed that the competitor product thickened at an accelerated rate. After 8 months in operation and 2000 tonnes drawn, the lubricant had become thick to the point that it could no longer be pumped. Conversely, the Alumol™ 145 saw a 19 month sump life and 4520 tonnes drawn. The results showed that the machine running Alumol™145 produced cleaner wire and had a much greater level of efficiency.
The performance was further enhanced with the subsequent introduction of Alumol™ VRX, a performance booster developed to extend the product life of the Alumol™ range. As the lubricating oil comes to the end of its life, the addition of Alumol™ VRX is utilised to reduce the viscosity and improve the lubricity of the oil thus maintaining the high quality of the finished wire.
