On the Runner and Ingate. (Water Model Test for the Gating System of Marine Propeller Casting, 2nd Report)

Masao Kanamori, Shôji Ueda and Hiroshi Sakaguchi


Abstract:

The effect of the design of the runner and the ingate on the rate and the quality of the flow is described. A comparison of flow properties in tapered, U-bent runner or runner with attached damper box and mono-hole or multiple-hole type ingate is discussed. The application of ``pre-filling'' method as a proposed pouring practice,by which aspiration and agitation are much rudused and the trapped air is washed away more quickly,is also outlined.
