Title:
SLIDING GATE
Document Type and Number:
WIPO Patent Application WO/2019/198745
Kind Code:
A1
Abstract:
This sliding gate has a flow path axial line gradient angle α of 5–75° between a flow path axial line direction for a flow path hole in each plate and a sliding surface vertical downstream direction. A sliding surface flow path axial line direction being the flow path axial line direction projected onto the sliding surface is different between the plates and changes in either the clockwise or counter clockwise direction as same progresses downstream. A molten metal forms a swirling flow inside the flow path hole of the sliding gate. The molten metal also forms a swirling flow inside an injection pipe on the downstream side of the sliding gate.
