Abstract

The invention discloses a sintering furnace for powder metallurgy products. The sintering furnace is composed of a sintering furnace feeding section 1, a sintering furnace sintering section 2, a sintering furnace cooling section 3 and a bracket 4. The sintering furnace for powder metallurgy products has the advantages of simple structure and small occupation space and is convenient to operate. Because carbinol is used for replacing liquid ammonia, the sintering furnace generates no pollution and no harm to a human body and is safe and reliable to use. The sintering furnace has the functions of protecting metallurgy sintering products, preventing products from being oxidized, preventing the products from decarbonising and has carburization effect on the products, and generated H2O can reduce the products in the sintering process.

Description

technical field [0001] The invention relates to an improvement of a sintering furnace for powder metallurgy products, in particular to a sintering furnace for powder metallurgy products with methanol decomposition protection atmosphere. Background technique [0002] The sintering of powder metallurgy products is to harden the pressed powder metallurgy product blanks in a sintering furnace whose temperature is lower than the melting point of the main components. The current sintering furnace for powder metallurgy products is composed of a sintering furnace feeding section, a sintering furnace sintering section, a sintering furnace cooling section, a liquid ammonia tank, a liquid ammonia decomposition electric furnace and a support. Section, set the inlet cover at the end of the feeding section of the sintering furnace, connect the cooling section of the sintering furnace at the rear end of the sintering section of the sintering furnace, set the outlet cover at the end of the ...
