| Abstract: | During the sintering of Mn-Zn ferrite cores,the process control of degumming below 600℃ has direct influence on the crack of the adobe,especially the large size adobe.In this paper,the characteristics and influence of airstream status,thermal transmission and temperature distribution in the degumming-district on the crack of Mn-Zn ferrite were analyzed for three different kinds of commonly used nitrogen-protected kilns in China.The method for measurement of temperature gradient in the kiln was also introduced,which provides a route to optimize the sintering of the Mn-Zn ferrite cores for the three kinds of kilns. |
