摘要： A PROCESS FOR THE DECARBONIZATION OF ELECTRICAL SHEET STEEL WHICH COMPRISES COMBINING THE DECARBONIZATION WITH THE DEVELOPMENT OF MAGNETIC CHARACTERISTICS OF THE STEELINTO ONE SINGLE STEP BY CONTACTING A STEEL STRIP OR SHEET AT 1,000*C. TO 1,300*C. WITH A MIXTURE OF WATER VAPOR AND HYDROGEN WHEREIN THE RATIO OF THE PARTIAL PRESSURE OF WATER VAAPOR TO THE PARTIAL PRESSURE OF HYDROGEN IS CONTROLLED BETWEEN 2X10**-4 TO 3X10**-3, AT A TEMPERATURE OF 1,00*C. AND 2X10**-4 TO 10**-1 AT A TEMPERATURE OF 1,300*C.
