Title: Continuous casting method of steel
Inventor: MIKI YUJI
IPC: B22D27/02
Filed: 2003-04-22
Abstract: <P>PROBLEM TO BE SOLVED: To manufacture high quality metallic products by casting slabs having less surface defects and inner inclusions, in continuous casting without blowing inert gases from a nozzle for feeding molten steel to a casting mold.  <P>SOLUTION: Three or more electromagnets (28) are arranged in the major side direction of a casting mold 10 and then, a magnetic field generated by adjacent coils 24 is essentially reversed. As a result, molten steel is actuated by a vibrating electromagnetic field in which a phase is essentially reversed. Also, a stationary magnetic field is superimposed in the thickness direction of the casting mold by a DC coil 34. Thus, in performing continuous casting while fluidity is locally excited, the maximum Lorentz's force driven by the magnetic field is made not less than 5,000 (N/m<SP>3</SP>) and not more than 13,000 (N/m<SP>3</SP>).  <P>COPYRIGHT: (C)2005,JPO&NCIPI
