Introduction
- The launder is of vital importance for the quality and energy-saving effect of molten aluminum metallurgy. Made of high-quality medium-density melted quartz refractory H2000 and pre-sintered at 800°C before assembly, the lining of HYDEB launder has high aluminum tolerance, low thermal conductivity, low shrinkage and high strength. The launder cover can be used to reduce heat loss by over 50% while a launder heating unit can be mounted to minimize the temperature drop of the launder, thus reducing the tapping temperature of molten aluminum and protecting some highly burnable alloying elements.
- There are a number of launder shapes, such as DC slot, elbow, tee joint and cross fitting. They can be combined flexibly together in use according to different site conditions.
