MTS 1500 —A robust (blockage-free), reliable, environmentally friendly, lower cost metal treatment station for aluminium foundries
Metal treatment is a critical part of the foundry process, which often has a significant impact on casting quality, scrap rates and costs. Existing practice often consists of hand fluxing or rotary degassing flux injection but both have important restrictions or limitations. Hand fluxing can be unreliable since it is operator dependant. Variations in addition rates, treatment times can cause major differences in efficiency and melt quality when cleaning, grain refining or doing sodium modification. This is especially true in High Pressure Die Casting (HPDC) where the number of ladles or furnaces treated can exceed 100 per day. Rotary degassing flux injection has resolved some of these issues by reducing the variability due to the human operator. It also has increased treatment consistency when performing a larger number of treatments per day. Unfortunately, the injection of flux through a rotating shaft requires a specially formulated and graded flux to prevent blockages. Fine particles smaller than 1 mm can become mushy during injection, whereas those larger them 2 mm can bridge inside the spinning shaft, which in both cases causes the treatment to breakdown. This blockage issue will limit the injection rate of the flux and hence can sometimes increase treatment time.
