The slow cooling device has the characteristics of stable product quality, low deformation possibility, and low damage possibility of protection equipment.
Description
Technical field
The present invention relates to a kind of annealing device, relate in particular to a kind of annealing device for powder metallurgy push-down sintering furnace.
Background technology
Present sintered metal product sintering furnace; by the sintering furnace feed zone; the sintering furnace sintering stage; the sintering furnace cooling section; ammonia tank; liquefied ammonia decomposes electric furnace and is configured to propping up; connect the sintering furnace feed zone at the front end of sintering furnace sintering stage; be provided with the charging flap in the end of sintering furnace feed zone; connect the sintering furnace cooling section in the rear end of sintering furnace sintering stage; set out the material flap in the end of sintering furnace cooling section; support is fixed on the bottom of sintering furnace sintering stage; before the sintering furnace cooling section is respectively equipped with on the sintering furnace feed zone; the final vacuum pipe; upper wall in sintering furnace sintering stage rear end is established the ammonia input pipe; ammonia tank decomposes electric furnace through liquefied ammonia and is connected on the ammonia input pipe by pipeline; liquefied ammonia in the ammonia tank decomposes electric furnace through liquefied ammonia and resolves into CO; CH4 and other hydrocarbon gas; in the ammonia input pipe is transported to the sintering furnace sintering stage; make the powder metallurgy blank under the carburizing atmosphere protection, carry out sintering, prevent that oxidation and decarbonization is to improve content of pearlite in alloy and and the comprehensive mechanical performance of product in sintering process.Sintering furnace is used widely at present as a kind of advanced person's heat treatment technics equipment, and its distinguishing feature is interrupted work exactly, with electric power or coal gas as energy medium.
Chinese patent CN201289290Y has announced a kind of " fast cooling type Medium frequency induction sintering furnace ", the circulating cooling system that this sintering furnace has adopted a cover to be made up of radiator, circulating fan, pipeline and passage, when furnace temperature is down to below 800 ℃, can open this system, realize the quick cooling of low temperature temperature-fall period.This sintering furnace can shorten the cool time of low temperature temperature-fall period, has shortened the sintering period to a certain extent.But the high temperature temperature-fall period that is positioned at more than 800 ℃ in furnace temperature still need adopt the water-cooling pattern cooling, and whole cooling stage still need expend the plenty of time, and the production cycle is still longer, and the performance of sintering furnace production capacity still is subjected to severely restricts.For example in the superhigh temperature sintering process to tantalum class refractory metal, because the holding temperature height, the high temperature temperature-fall period is long, and this sintering furnace can not make fully be shortened total cool time.But can produce harm to equipment, make stove join easy deformation cracking, the unstable product quality of producing, internal stress is big, shortcomings such as difference of hardness.
Summary of the invention
The object of the present invention is to provide a kind of constant product quality that has, the annealing device that is used for powder metallurgy push-down sintering furnace of characteristics such as not yielding and protection equipment is not fragile.
For solving the problems of the technologies described above, the present invention adopts following technical scheme: a kind of annealing device for powder metallurgy push-down sintering furnace, be installed between sintering furnace and the cool furnace, comprise body of heater, slow cooling blower fan and control system, described slow cooling blower fan is arranged on the inwall tail end of described body of heater, described slow cooling blower fan is connected with described control system, described body of heater is the sulfur sesquioxide stove, be provided with transport establishment in the described sulfur sesquioxide stove, the inner bag of described sulfur sesquioxide stove coats insulation materials such as glass fibre outward, the outer iron sheet that coats of described sulfur sesquioxide stove.
In a preferred embodiment of the present invention, described control system comprises the fuzzy temperature controller.
In a preferred embodiment of the present invention, described transport establishment is connected with described control system.
Annealing device for powder metallurgy push-down sintering furnace of the present invention has constant product quality, characteristics that not yielding and protection equipment is not fragile etc.
Description of drawings
