ALUMINUM WEIGHING MEASUREMENT IN TILTING FURNACES

摘要

The best way to prepare aluminum alloys is to know the heel weight at the end of the previous cast and the weight of pure aluminum added. Many systems have been tried to measure the aluminum weight in tilting furnaces, including load cells, lasers and radars. None of these systems are satisfactory. A measuring system based on the pressure in cylinders used to tilt furnaces has been developed. It is easily retrofitted to existing furnaces and measure weight with an accuracy of +- 450 lbs. The system can be used to monitor the weight whether it is a heel or a completely full furnace. It can also measure weight in real time during the transfer from the holding furnace. Results of the system in plant operation are presented.
