The invention discloses a non-oriented
electrical steel plate with extremely low content of Ti and a
smelting method for the non-oriented
electrical steel plate. The method comprises the following steps of: 1) performing hot
metal pretreatment and converter
smelting, namely
smelting the following chemical components: less than or equal to 0.005 weight percent of C, 0.1 to 1.6 weight percent of Si, 0.1 to 0.6 weight percent of Mn, less than or equal to 0.2 weight percent of P, less than or equal to 0.005 weight percent of S, less than or equal to 0.005 weight percent of Al, less than or equal to 0.005 weight percent of N, 0.005 to 0.02 weight percent of O, 0.0002 to 0.001 weight percent of Ti, and the balance of Fe and inevitable inclusions, and reducing the
slag takeover by adopting
slag stopping operation in a converter so as to ensure that the
slag amount of the surfaces of steel ladles is less than or equal to 20kg in each
ton of steel after the tapping of the converter is finished; and 2) performing Ruhrstahl-Heraeus (RH) refining, and weakly deoxidizing by using ferroaluminum and
ferrosilicon sequentially after the
decarburization of the RH refining is finished so as to ensure that the content of free
oxygen of weakly deoxidized
molten steel is 100 to 300ppm. The production of non-oriented
electrical steel plates with extremely low content of Ti is realized by controlling the slag takeover of the tapping process of the converter, weakly deoxidizing by using the ferroaluminum and the
ferrosilicon sequentially, and strictly controlling the content of
oxygen in steel after the refining is finished.
