MOLTEN METAL FILTRATION SYSTEM AND PROCESS

摘要

88-235 The present invention relates to an improved molten metal filtration system. The system comprises at least one filtration assembly positioned within a filter chamber intermediate a molten metal inlet and a molten metal outlet and a dam wall positioned intermediate each filtration assembly and each molten metal outlet. Each dam wall prevents the initial molten metal used to prime the filter(s) in each filtration assembly from proceeding directly to the outlet. Instead, the dam wall collects the initial molten metal and forms it into a pool of heated molten metal. This pool has been found to reduce the amount of heat loss during the filtration process. A process for using the filtration system of the present invention is also described.
