MOLD FOR CONTINUOUS CASTING

摘要

PURPOSE:To prevent the breakout in the outlet of a casting mold by providing a flow rate regulating part having plural through-holes in a molten metal flow passage and embedding heating elements into said part around the through-holes. CONSTITUTION:The heating elements 2 are provided around a crucible 1 and the casting mold 3 is disposed in the lower part of the crucible 1. The flow rate regulating part 6 is disposed to close the flow passage to the molten metal flow passage 4 of the casting mold 3 and the plural through-holes 7 are provided therein. The heating elements 5 such as heaters are attached around the through- holes 7. A dummy bar 8 is preliminarily positioned in the lower part of the mold 3 and casting is started. The bar 8 is gradually pulled down to continuously solidify the molten metal. The heating elements 5 control the molten metal temp. and the viscosity resistance of the molten metal flowing in the through- holes 7 prevents the excessive outflow of the molten metal. The generation of the breakout in the outlet of the casting mold is prevented by the above- mentioned method.
