Abstract
Fully dense long ingots are produced by the bottom pouring method and apparatus of the present invention. A solidification sequence is achieved which is conducive to eliminating solidification shrinkage and piping. The set-up of the bottom poured ingot molds facilitates a solidification sequence starting from the top and then down the ingot mold and then up the down pour pipe.
Claims15
In a bottom pouring ingot mold having a down pour pipe with an upper portion, a middle portion, and a lower portion, one or more ingot molds, each of said one or more ingot molds with an upper portion, a middle portion, and a lower portion, and one or more runners connecting said down pour pipe to each of said one or more ingot molds, a method for producing ingots comprising the steps of:
- inserting a first heating element into said down pour pipe for the purpose of pre-heating said upper and middle portions of said down pour pipe;
- inserting a second heating element into each of said one or more ingot molds, for the purpose of pre-heating said lower and middle portions of each of said ingot molds;
- removing said first heating element from said down pour pipe and said second heating element from each of said ingot molds;
- and
- pouring molten metal into said down pour pipe, such that said molten metal flows into said one or more ingot molds via said one or more runners.
In a bottom pouring ingot mold having a down pour pipe with an upper portion, a middle portion, and a lower portion, an ingot mold, with an upper portion, a middle portion, and a lower portion, and a runner connecting said down pour pipe to said ingot mold, a method for producing a metal ingot comprising the steps of:
- inserting a first heating element into said down pour pipe for the purpose of pre-heating said upper and middle portions of said down pour pipe to a temperature below the liquidus temperature of said molten metal;
- inserting a second heating element into said ingot mold, for the purpose of pre-heating said lower and middle portions of said ingot mold to a temperature below the liquidus temperature of said molten metal;
- removing said first heating element from said down pour pipe and said second heating element from said ingot mold;
- and
- pouring molten metal into said down pour pipe, such that said molten metal flows into said ingot mold via said runner.
