Abstract
A method and apparatus for alternating pouring into molds, casts or refining hearths from a common hearth in a furnace. The apparatus provides a main hearth, a plurality of optional refining hearths, and a plurality of casting molds or direct molds whereby the refining hearths and molds define at least two separate ingot making lines. The main hearth alternatively pours into a first ingot making line while the other line is prepared, and vice versa allowing for continuous melting.
Claims20
An apparatus for alternative pouring of ingots, the apparatus comprising:
- a main hearth defining a melting cavity therein with a first and a second opposed overflows;
- a first and a second molds aligned respectively with the first and second overflow to be in fluid communication therewith;
- at least one torch overhead of the main hearth for selective heating of the contents of the main hearth;
- and
- at least one supplemental torch overhead of each of the molds for selectively heating of the contents of molds.
A method for alternating molten material pouring comprising:
- melting of the contents within a main hearth with a first and a second opposed overflows to define a molten material;
- pouring of molten material from the main hearth into a first mold adjacent a first end of the main hearth to define aafirst molded body;
- and
- pouring of molten material from the main hearth into a second mold adjacent a second end of the main hearth to define a second molded body.
A method for alternating ingot pouring comprising:
- melting of the contents within a main hearth with a first and a second opposed overflows to define a molten material;
- pouring of molten material from the main hearth into a first refining hearth adjacent a first end of the main hearth;
- pouring of molten material from the first refining hearth into a first mold adjacent an end of the refining hearth to define a first molded body;
- pouring of molten material from the main hearth into a second refining hearth adjacent a second end of the main hearth;
- and pouring of molten material from the-second refining hearth into a second mold adjacent an end of the second refining hearth to define a second molded body.
