Strip steel, low carbon content steel plates, low carbon content and process for producing the same

摘要

"Blades of steel of low carbon content and steel plates, low carbon content and process for producing the same.The present invention provides a blade of steel of low carbon content and a steel plate of low carbon in which the formation of surface defects can be surely prevented.Avoiding the aggregation of inclusions in molten steel and the inclusions finely dispersed on the plate or steel plate, and a process for producing the plate or steel plate.The present invention provides a process comprising the steps of descarburar a molten steel so as to produce a carbon concentration up to 0.01% by mass.Pre desoxidar cast steel by adding al to produce a concentration of dissolved oxygen from 0.01 to 0.04 in the mass, by adding at least if you and her and / or EC.And lingotando - if the molten steel, and a steel sheet and steel plate obtained by the process.
