| titleOfInvention | One kind preparing high-performance silicon steel method of magnesium oxide by dolomite |
| abstract | The present invention relates to grain-oriented Si steel sheet manufacturing fields, it is specially a kind of that high-performance silicon steel method of magnesium oxide is prepared by dolomite, it solves in existing grain-oriented Si steel sheet manufacture because using bittern method to prepare the problems such as adhesion existing for silicon steel magnesia is poor, magnetic flux density is low, the concession of insulating film layer bottom is high.Dolomite is first passed through calcining by the present invention, it is carbonized in carbonators after carrying out chemical combination with water, then solid carbonic acid calcium and magnesium bicarbonate aqueous solution are separated by filtration, obtained magnesium bicarbonate aqueous solution is filtered by being pyrolyzed, step calcination after magnesium carbonate is obtained, high performance silicon steel magnesia is obtained after air-flow crushing is packed.The present invention is unique with production technology, cost is relatively low, three wastes generate, and can significantly improve grain-oriented Si steel sheet adhesion, electromagnetic performance, trade mark rate, can be promoted the use of on a large scale in grain-oriented Si steel sheet producer. |
