Japanese Patent JP6818980
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To manufacture a sound and highly clean ingot with a lower cost effectively preventing occurrence of drift generation and entrainment of an ingot inside material using a simple facility configuration when pouring multiple ingots by bottom pouring from one runner.SOLUTION: A bottom pouring ingot making facility 1 according to the invention is an ingot making facility making an ingot by introducing a molten metal to a branch passage 4 branched with T shape from a runner 3 and pouring the molten metal to a mold 5 placed ahead the branch passage 4, a recess 11 recessed as a curved shape upward is formed on a branch part 10 where the branch passage 4 is branched with T shape upwardly from the runner 3, a prescribed relationship between a curvature radius X and an inner diameter d is satisfied, where a curvature radius of a curve surface of the recess 11 is X, and an inner diameter of the runner 3 is d.SELECTED DRAWING: Figure 1
