Abstract
A method for production of a cooling plate (50, 80) with integrated coolant ducts (52, 84) for iron and steel making furnaces, in particular blast furnaces, is described. A preform of the cooling plate (50, 80) is continuously cast by a continuous casting mould (10), wherein rod-shaped inserts (28) in the casting duct (20) of the continuous casting mould (10) produce in this preform ducts (52, 84) running in the continuous casting direction, which form coolant ducts in the finished cooling plate.
Claims18
A method of manufacturing a cooling plate for iron and steel making furnaces, said method comprising the steps of:
- continuously casting an ingot of copper with cast-in ducts extending in the continuous casting direction;
- and
- cutting out a plate of said ingot of copper by two cuts at right angles to the continuous casting direction, whereby two end faces are formed, wherein said cast-in ducts form openings;
- drilling connection holes for feed and return pipes from a plate surface into said cast-in ducts;
- sealing said openings in said two end faces of said plate;
- and
- wherein said cast-in ducts remain continually open to form coolant ducts in the finished cooling plate.
A method of manufacturing a cooling plate for iron or steel making furnaces, said method comprising the steps of:
- continuously casting an ingot of copper using a continuous casting mould with rod-shaped inserts, wherein said rod-shaped inserts produce cast-in ducts extending through said ingot of copper in the continuous casting direction;
- and
- using said ingot of copper with said cast-in ducts as a preform of said cooling plate;
- and
- transforming said preform of said cooling plate into a finished cooling plate, wherein said cast-in ducts remain continually open to form coolant ducts in the finished cooling plate.
