Abstract

The invention belongs to the technical field of sintering furnaces, and particularly relates to a powder metallurgy sintering furnace and a sintering process thereof, the process comprises the following steps: S1, raw material preparation: selecting three kinds of powder of iron, copper, aluminum, titanium, nickel, tungsten and aluminum oxide as powder raw materials; s2, the selected powder raw materials are poured into a stirring machine to be fully mixed; according to the powder metallurgy sintering furnace and the sintering process thereof, by arranging the reciprocating suction mechanism, the effect of reciprocating suction of waste gas generated in the sintering cavity of the sintering furnace equipment is achieved, the reciprocating suction mechanism is used in cooperation with the circulating filtering mechanism, and the effects of multiple purification and filtering of the waste gas are achieved; the vacuum sintering furnace device for the metal powder metallurgy technology solves the problems that an existing vacuum sintering furnace device for the metal powder metallurgy technology is poor in tail gas treatment effect, a large amount of harmful gas can be generated in the sintering process of the sintering furnace device, and if the gas cannot be effectively treated and is discharged into the atmosphere, the air can be seriously polluted.

Description

technical field [0001] The invention relates to the technical field of sintering furnaces, in particular to a powder metallurgy sintering furnace and a sintering process thereof. Background technique [0002] Powder metallurgy sintering furnace is a heat treatment equipment that uses metal powder (or a mixture of metal powder and non-metal powder) as raw material, and is shaped and sintered into metal or alloy parts. [0003] However, the existing vacuum sintering furnace for metal powder metallurgy process has the defect that the exhaust gas treatment effect is not good. During the sintering process of the sintering furnace, a large amount of harmful gases will be generated. If these gases cannot be effectively treated, they will be discharged into the atmosphere. It will cause serious pollution to the air. Although there are powder metallurgy sintering furnaces with waste gas treatment mechanisms on the market, when the waste gas in the powder metallurgy sintering furnace ...
