Abstract

The invention discloses an intelligent circulating vacuum pressure sintering furnace and a method thereof, comprising a control center and a ring-shaped runway arranged outside the ring-shaped runway, at least one calciner is distributed on the ring-shaped runway, the calciner and the control center The outer side is connected and fixed, the control center is provided with a rotary drive, and the transmission end of the rotary drive is provided with a positioning rod for connecting to the outside of the calciner; the calciner includes a lower furnace body and an upper furnace that is arranged on its upper port. Body, the surface of the upper and lower furnace body is provided with heat insulation layer, and the left and right sides of the lower furnace body are respectively fixed with an opening and closing telescopic rod. According to the advantages and disadvantages of the existing mesh belt furnace and bell furnace, this application designs an intelligent circulating vacuum The pressure sintering furnace can not only achieve the high production efficiency of the mesh belt furnace, but also greatly improve the product quality, so as to realize the localization of the brake pads of the high-speed train trains and break the blockade of foreign high-precision technology in high-speed trains.

Description

technical field [0001] The invention relates to the technical field of sintering manufacturing, in particular to an intelligent circulating vacuum pressure sintering furnace and its method. Background technique [0002] There are two types of equipment used in the sintering process of domestically produced friction blocks: mesh belt furnaces and bell jar furnaces. Mesh belt furnaces generally have muffle-protected mesh belts to realize continuous transportation of parts in the furnace. The main It is used for sintering of powder metallurgy products, reduction of metal powder and pre-sintering, firing or heat treatment of electronic products in protective atmosphere or air. The characteristics are: the whole set of equipment is composed of three parts: the furnace body, the mesh belt transmission system and the temperature control system. The furnace body is composed of feeding section, pre-burning section, sintering section, slow cooling section, water cooling section and d...
