Method for sintering manganese zinc ferrite magnetic core by adding zinc ingots in densifying atmosphere

Номер: CN104446422A
Принадлежит:

The invention discloses a method for sintering a manganese zinc ferrite magnetic core by adding zinc ingots in a densifying atmosphere. The method comprises a step of sintering a manganese zinc ferrite magnetic core blank in a kiln at a heating section, a heat preservation section and a cooling section which have corresponding temperature conditions and atmosphere environments according to a time sequence. The method is characterized by comprising the following steps of placing zinc in the kiln and sintering with the blank at the same time; at the heating section, adding nitrogen; and when the temperature reaches 1340-1360 DEG C at the heating section, stopping the heating, and transferring the blank to the heat preservation section. The method has the positive effects that the zinc ingots and the specific atmospheres are adopted in the method for sintering the manganese zinc ferrite magnetic core, so that the volatile quantity of zinc in the product under a high temperature condition is ...
