Title:
FILTER-FREE LIQUID RISING TUBE FOR USE IN LOW-PRESSURE CASTING
Document Type and Number:
WIPO Patent Application WO/2018/068528
Kind Code:
A1
Abstract:
A filter-free liquid rising tube for use in low-pressure casting; a liquid intake hole (2) is arranged at a bottom portion of a liquid rising tube (1); the liquid intake hole is in communication with the inside of the liquid rising tube; and an entrance area of the liquid intake hole is 10–60% of a flow area of the liquid rising tube. The liquid rising tube enables low-pressure casting production without placing a filter therein, reducing the cost and failure rate in a fully automatized low-pressure casting production line, facilitating the handling of a discharge head at the sprue, and further reducing iron added to remelting scraps.
