| titleOfInvention | Method for preparing magnesium oxide for high-performance silicon steel through dolomite |
| abstract | The invention relates to the field of orientation silicon steel manufacturing, in particular to a method for preparing magnesium oxide for high-performance silicon steel through dolomite. The problems that in the existing orientation silicon steel manufacturing process, magnesium oxide for silicon steel is prepared through a bittern method, adhesiveness is poor, the magnetic flux density is low, insulation film bottom layer concession is high are solved. The method comprises the steps that firstly, dolomite is roasted, subjected to chemical combination with water and then carbonized in a carbonizing tower; secondly, solid calcium carbonate and a magnesium bicarbonate aqueous solution are filtered and separated, the obtained magnesium bicarbonate aqueous solution is pyrolyzed and filtered, magnesium carbonate is obtained, then subjected to multi-step calcination, smashed through air flow and packaged, and magnesium oxide for the high-performance silicon steel is obtained. According to the method, the production process is unique, cost is low, three wastes are not generated, the adhesiveness, electromagnetic performance and grade rate of the orientation silicon steel can be remarkably improved, and the method can be applied and popularized in orientation silicon steel factories on a large scale. |
