Powder metallurgy sintering furnace having high practicability

Abstract

The invention discloses a powder metallurgy sintering furnace having high practicability. The powder metallurgy sintering furnace includes a furnace body; a bottom seat is fixed on the bottom of the furnace body; a door is movably hinged to one side of the furnace body; an observation window is arranged on the door; heating tubes which are evenly distributed are arranged on a top wall of an inner cavity of the furnace body; sintering holders are distributed at equal intervals and are arranged in inner walls of the furnace body; sintering frames are arranged on the sintering holders; sintering nets are arranged inside the sintering frames; an exhaust pipe and a cooling liquid tank are arranged on the top of the furnace body; and a cleaner is arranged on the exhaust pipe. The powder metallurgy sintering furnace can sinter lots of metal powder once, can improve the sintering efficiency, is excellent in warming effect, can avoid energy loss in a sintering process, and can save resources; the cleaner arranged on the exhaust pipe can effectively clean smoke generated in sintering, and pollution to environment due to direct emission of unprocessed smoke can be avoided.

Description

technical field [0001] The invention relates to the technical field of powder metallurgy sintering furnace equipment, in particular to a powder metallurgy sintering furnace with strong practicability. Background technique [0002] 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 powder metallurgy sintering furnace is an important equipment for the sintering of powder metallurgy products. Furnace, the sintering rate is low, and the heat preservation effect is poor, the heat in the sintering is easy to lose during the sintering process, resulting in energy waste, and the traditional powder metallurgy sintering furnace is easy to generate smoke during the sintering process. It contains a lot of dust particles and harmful substances. If it is directly discharged, it will not only pollute the environment, but also seriously affect t...

[0002] 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 powder metallurgy sintering furnace is an important equipment for the sintering of powder metallurgy products. Furnace, the sintering rate is low, and the heat preservation effect is poor, the heat in the sintering is easy to lose during the sintering process, resulting in energy waste, and the traditional powder metallurgy sintering furnace is easy to generate smoke during the sintering process. It contains a lot of dust particles and harmful substances. If it is directly discharged, it will not only pollute the environment, but also seriously affect the health of the staff. In addition, most of the existing powder metallurgy sintering furnaces are opaque, which is inconvenient for the staff to observe the powder metallurgy products. The sintering situation brings inconvenience to the work of the staff
