Abstract

The invention discloses a vacuum degreasing sintering furnace. The furnace comprises a furnace body, and a thermal insulation cylinder and thermal insulation doors which are arranged inside the furnace body, wherein the thermal insulation doors are arranged at the two ends of the thermal insulation cylinder, and a heating body is arranged inside the thermal insulation cylinder; furnace doors are hinged to the two ends of the furnace body, any one of the two furnace doors is provided with a cooling system, a gas inlet pipe is arranged on the furnace body and is communicated with a gas source; the furnace body is connected with a graphite guide rail through a stand column, the graphite guide rail is used for supporting and conveying a work bin and is provided with a plurality of rolling needle bearings, and the work bin can move on the graphite guide rail; a gas inlet valve and a cooling hole are arranged on the work bin, and the cooling hole can be closed by a movable upper cover on thefurnace body; a gas exhaust flange is arranged at the lower part of the furnace body, is communicated with a vacuum pump, and is connected with a lower degreasing pipe and an upper degreasing pipe insequence, and the upper degreasing pipe is driven by a lifting mechanism to move in the lower degreasing pipe and is communicated or separated from a gas discharging hole of the work bin. The vacuumdegreasing sintering furnace has the advantage of high production efficiency.

Description

technical field [0001] The invention relates to the technical field of industrial furnaces, in particular to a vacuum degreasing sintering furnace. Background technique [0002] Sintered products are usually placed in a material box and fired in a sintering furnace. The material box (also called muffle) is made of graphite and is a very important device in a vacuum degreasing and sintering integrated furnace. The reason why the material box is used to wrap the product (processing object) is that its heat conduction effect is very good, the heat loss is very small, and it can evenly ensure that the temperature of each place in the material box is consistent. When the heating body is heated, the temperature passes through radiation. Conducted to the material box, the temperature of the material box rises, the temperature of the material box is transmitted to the ceramic plate, and then transmitted to the product through the ceramic plate, the conduction temperature is very uni...
