| titleOfInvention | Coating based on magnesium oxide and process for producing steel with oriented crystals for electroengineering purposes |
| abstract | The present invention provides an annealing separator composition for coating grain oriented electrical steel prior to the final high temperature anneal for secondary grain growth. The magnesia based coating contains at least 15 %, particularly at least 20 % silica on a water free basis. The large silica additions limit the interface between the coating and the base metal and result in a thick glass which is easily removed. The magnesia coating develops excellent magnetic properties and does not require the normal strong acid cleaning or special abrasive means to remove the glass film which forms. The bare electrical steel, which may be coated to enhance the punching properties, has improved the die life because the hard glass film has been substantially removed. |
