Vacuum sintering of rare earth permanent magnet materials, sintered diamond tools (welding) and vacuum heat treatment process. The device has a large amount of exhaust, high vacuum, controlled temperature uniformity and no leakage characteristics.
The products inner loop, the outer loop, double chamber to protect feed and multi-room (Taiwan) combined feed and other forms.
Temperature vacuum sintering furnace structure Introduction
Double water wall furnace, heating chamber with stainless steel molding, aluminum silicate fiber outsourcing tile-like molybdenum insulation, heating element the internal install molybdenum strips. According to the sintering process large amount of gas and dust associated with the phenomenon, the vacuum system with high pumping speed trap additional powder high vacuum diffusion pump unit. By mechanical pumps, Roots pumps, diffusion pumps.
The high pumping speed of the Roots pump reduces the diffusion pump outlet pressure, improve the diffusion pump working conditions, the shortened rough time and sintering process stage deflated rapidly excreted, to avoid the re-oxidation of the surface of the sintered material.
