Electromagnetic stirrer arrangement with continuous casting of steel billets and bloom

Abstract

An electromagnetic stirrer arrangement includes a housing having a bottom opening and a top opening. An electromagnetic stirrer is positioned inside the housing. A modular mold assembly includes a mold, a water jacket, a top plate, a bottom plate and a plurality of rods connecting the top and bottom plates. The mold has an open top and an open bottom. The top plate is positioned proximate to the open top of the mold and the bottom plate is positioned proximate to the open bottom of the mold. The connecting rods extend between and securing together the top and bottom plate. The modular mold assembly can easily be replaced by inserting it into or removing from the housing.

1 . An electromagnetic stirrer arrangement comprising:
 a housing having a bottom opening and a top opening;   an electromagnetic stirrer positioned inside said housing;   a modular mold assembly including a mold, a top plate, a bottom plate and a plurality of connecting rods, said mold having an open top and an open bottom, said top plate being positioned proximate said open top of said mold and said bottom plate positioned proximate said open bottom of said mold, said rods extending between and securing together said top and bottom plate; and   wherein said modular mold assembly is insertable and removable from said housing.   
     
     
         2 . The electromagnetic stirrer arrangement of  claim 1  wherein said plurality of connecting rods comprises four (4) rods positioned in an evenly spaced arrangement around said mold. 
     
     
         3 . The electromagnetic stirrer arrangement of  claim 1  wherein said plurality of connecting rods comprises eight (8) rods positioned in an evenly spaced arrangement around said mold. 
     
     
         4 . The electromagnetic stirrer arrangement of  claim 1  wherein said modular mold assembly further comprises a water jacket positioned between said plurality of connecting rods and said mold for directing cooling fluid over an exterior surface of said mold. 
     
     
         5 . The electromagnetic stirrer arrangement of  claim 1  wherein said bottom plate includes a central opening and said top plate includes a central opening, said mold being positioned within each said central opening. 
     
     
         6 . The electromagnetic stirrer arrangement of  claim 1  wherein said bottom plate central opening and said top plate central opening each include a groove and receives an o-ring therein, said o-ring engaging said central opening and an exterior surface of said mold. 
     
     
         7 . The electromagnetic stirrer arrangement of  claim 1  wherein said electromagnetic stirrer is supplied with an A.C. current at a frequency of 1 to 10 Hz and intensity between 50 and 550 Amps. 
     
     
         8 . The electromagnetic stirrer arrangement of  claim 1  wherein said housing extends between said top plate and said bottom plate to encapsulate said mold. 
     
     
         9 . An electromagnetic stirrer arrangement comprising:
 a housing having a bottom opening and a top opening;   an electromagnetic stirrer positioned inside said housing;   a modular mold assembly including a mold, a top plate, a bottom plate and a water jacket, said mold having an open top and an open bottom, said top plate being positioned proximate said open top of said mold and said bottom plate positioned proximate said open bottom of said mold, said water jacket positioned around said mold to form a channel therebetween for directing cooling fluid over an exterior surface of said mold; and   wherein said modular mold assembly is insertable and removable from said housing.   
     
     
         10 . The electromagnetic stirrer arrangement according to  claim 9  further comprising a plurality of connecting rods extending between and securing together said top and bottom plate. 
     
     
         11 . The electromagnetic stirrer arrangement according to  claim 10  wherein said plurality of connecting rods comprises four (4) rods positioned in an evenly spaced arrangement around said mold. 
     
     
         12 . The electromagnetic stirrer arrangement according to  claim 10  wherein said plurality of connecting rods comprises eight (8) rods positioned in an evenly spaced arrangement around said mold. 
     
     
         13 . The electromagnetic stirrer arrangement of  claim 9  wherein said bottom plate includes a central opening and said top plate includes a central opening, said mold being positioned within each said central opening. 
     
     
         14 . The electromagnetic stirrer arrangement of  claim 10  wherein said bottom plate central opening and said top plate central opening each include a groove and receives an o-ring therein, said o-ring engaging said central opening and an exterior surface of said mold. 
     
     
         15 . The electromagnetic stirrer arrangement of  claim 11  wherein said electromagnetic stirrer is supplied with an A.C. current at a frequency of 1 to 10 Hz and intensity between 50 and 550 Amps. 
     
     
         16 . The electromagnetic stirrer arrangement of  claim 9  wherein said housing extends between said top plate and said bottom plate to encapsulate said mold.
