Improved magnetic core sintering furnace

Abstract

The invention provides an improved magnetic core sintering furnace which comprises a furnace body with a furnace chamber, wherein a radiating region reaction chamber, a pre-heating region reaction chamber, a low-temperature region reaction chamber, a high-temperature region reaction chamber and a rubber discharge reaction chamber are sequentially arranged in the furnace chamber from top to bottom; the pre-heating region reaction chamber communicates with a charge hole; the pre-heating region reaction chamber is connected with the rubber discharge region reaction chamber through a first feeding tube; the rubber discharge region reaction chamber is connected with the low-temperature region reaction chamber through a second feeding tube; the low-temperature region reaction chamber is connected with the high-temperature reaction chamber through a third feeding tube; the high-temperature region reaction chamber is connected with the radiating region reaction chamber through a fourth feeding tube; the radiating region reaction chamber communicates with a discharge hole; the radiating region reaction chamber is separated from the pre-heating region reaction chamber through a heat exchange plate, and the pre-heating region reaction chamber is separated from the low-temperature region reaction chamber through a heat exchange plate; the low-temperature region reaction chamber is separated from the high-temperature region reaction chamber through a heat insulating plate; a thermal-insulation sandwich layer is arranged between the high-temperature region reaction chamber and the rubber discharge region reaction chamber; and the thermal-insulation sandwich layer communicates with the rubber discharge region reaction chamber through a heat transmission pipeline.

Description

technical field [0001] The invention belongs to the technical field of machinery, and relates to a sintering device, in particular to an improved magnetic core sintering furnace. Background technique [0002] The sintering furnace is a kind of mutual bonding of the solid particles of the ceramic green body at high temperature, the grains grow, the voids (pores) and grain boundaries gradually decrease, and the total volume shrinks and the density increases through the transfer of materials. A furnace that becomes a dense polycrystalline sintered body with a certain microstructure. The sintering furnace is mainly used for the sintering of ceramic powder, ceramic ferrule and other zirconia ceramics, the sintering of diamond saw blades, and can also be used for heat treatment of copper, steel strip annealing, etc. [0003] In the production process of the magnetic core, the pressed and cut magnetic core needs to be put into a tunnel sintering furnace for sintering. The traditi...
