Abstract


With the rapid development of the sinter cooling process , the the sinter cooling devices are becoming increasingly perfect. The annular cooling machine is widely used in the iron and steel enterprises , so that the annular cooler cooling become one of the new sintering capacity bottlenecks . Therefore , the ring cooler system optimized sintering production development trend . This article is mainly for domestic ring cooler air leakage serious situation, improvement and optimization analysis on the structure of the sealing of the annular cooler . The main content of this study include : magnetic fluid sealing technology used in the ring cooler seal design magnetic fluid sealing device ; study magnetic fluid seal mechanism , suffered in a magnetic field , the magnetic field force analysis of magnetic fluid sealing medium derived magnetic hydrostatic seal pressure differential pressure formulas ; the combination ring structural characteristics cooler , a simplified three-dimensional solid model , using the finite element numerical analysis software on the sealed part of the ring cooler obtain the seal gap magnetic field intensity distribution draw rectangular pole seal structure parameter ranges ; through the analysis of the magnetic fluid sealing structure , and design a simple magnetic fluid seal experimental apparatus for experimental research . Theoretical analysis and experimental results show that : the magnetic fluid seal is an effective and feasible method annular cooler seal ; magnetic fluid sealing structure design of the sealing pressure capacity , reasonable design sealing structure , can effectively improve the sealing resistance pressure capability. These results for the contact site in the future to actually take corresponding measures , to provide a basis to find reasonable ways and means to improve the quality of the sinter sinter ring cooler cooling process .
