一、绪言众所周知,为使有利夹杂MnS和AlN等充分固溶,取向硅钢坯的加热温度通常大于1300℃。由于加热温度极高,取向硅钢坯的烧损十分严重,高达4％左右。本方法可以显著降低步进炉中取向硅钢坯的烧损。 First, the introduction As we all know, in order to facilitate the inclusion of MnS and AlN sufficient solid solution, the orientation of the silicon billet heating temperature is usually greater than 1300 ℃. As the heating temperature is very high, the burning of oriented silicon steel billet is very serious, up to about 4%. The method can obviously reduce the burning of the oriented silicon steel billet in the stepping furnace.
