Steel plate for enameling, having improved formability, anti-aging property, and enameling properties, and process for producing the same

   
   

Disclosed is the provision of a non-aging, highly anti-seed and anti-black-speck steel plate for enameling without relying upon decarbonization-denitrification annealing involving increased production cost, and without the addition of expensive elements, such as niobium and titanium involving increased alloying cost. This steel plate is produced by adopting a steel composition comprising, by weight, carbon: not more than 0.0018%, silicon: not more than 0.020%, manganese: 0.10 to 0.30%, phosphorus: 0.010 to 0.030%, sulfur: not more than 0.030%, aluminum: not more than 0.005%, nitrogen: 0.0008 to 0.0050%, boron: not more than 0.0050% and not less than 0.6 time the nitrogen content, and oxygen: 0.010 to 0.05%, and regulating the chemical composition of the steel and regulating mainly hot rolling conditions to regulate the form of nitrides.

Se divulga la disposición de un no-envejecimiento, altamente contra-semilla y placa de acero de la contra-negro-mota para esmaltar sin confiar en el recocido de la descarbonizacio'n-desnitrificacio'n que implica coste de producción creciente, y sin la adición de elementos costosos, tales como niobium y titanio que implican coste de aleación creciente. Esta placa de acero es producida adoptando una composición de acero que abarca, por el peso, carbón: no más que 0.0018%, silicio: no más que 0.020%, manganeso: 0.10 a 0.30%, fósforo: 0.010 a 0.030%, sulfuro: no más que 0.030%, aluminio: no más que 0.005%, nitrógeno: 0.0008 a 0.0050%, boro: no más que 0.0050% y no no menos que 0.6 vez el contenido del nitrógeno, y oxígeno: 0.010 a 0.05%, y regulación de la composición química del acero y regulación principalmente de condiciones del balanceo caliente para regular la forma de nitruros.
