Description
Technical field
It is manufactured the present invention relates to graphite material and carries out the cooling equipment technical field of Intelligent forced to open-type ring-type roasting furnace,
It is open-type ring-type roasting furnace Intelligent forced cooling device, which can control special graphite and ultra high power
Connector roasting product cooling rate and tapping temperature reduce the generation of roasting with graphitizing process stress cracking, are graphite material systems
The key technology of fabricate-heat treatment process reduction rejection rate.
Background technique
With with nuclear power, photovoltaic, fiber manufacturing, semiconductors manufacture, rocket and MISSILE LAUNCHING, electrical discharge machining, high-end
Large-scale heat exchange equipment, 100 tons of high speed developments to fields such as 200 tons of large capacity uhp electric arc furnaces, to hyperfine structure, thin knot
The demand of structure, middle fine texture special graphite and Φ 600mm or more specification ultra high power graphite electrode greatly is continuously increased, ultra-fine
The manufacture of the big specification ultra high power connector of structure, fine texture and middle fine texture special graphite and Φ 600mm or more is both needed to carry out
Roasting heat treatment, is generally roasted in open type circular furnace, and the product cooling rate after firing has stringent with tapping temperature
It is required that tapping temperature is high, big with the ambient temperature temperature difference, thermal stress is big, and product structure is thinner, is more also easy to produce stress cracking, cooling
Excessive velocities can also generate stress cracking, after stress cracking cooling meat, it is difficult to check and, be heat-treated in graphitizable high temperature
When, Expanding of stress crack forms big crackle, leads to scrap of the product, therefore the control of the cooling rate and tapping temperature of roasted product
It is very crucial.Natural cooling is generally leaned in the cooling of open type circular furnace, and cooling velocity is very slow, to reach the tapping temperature of requirement,
Many stoves are needed to be cooled down, the open type circular furnace dual system operation now with many producers has been built to 38--40 platform furnace
Son.Our company has 30 Room open type circular furnaces, needs 7 stoves cooling when leaning on natural cooling, at most can only the heating operation of Room 5, be
Increase operation furnace chamber and promote production capacity, need to accelerate cooling rate, our company will not cause stress to split to how improving cooling rate
Line has made intensive studies analysis, and innovative design has gone out a set of Intelligent forced cooling device, solves the control of cooling rate, reduces
It is super to realize the big specification of hyperfine structure, fine texture, middle fine texture special graphite and Φ 600mm or more for product tapping temperature
High power connector is unstressed crackle waste product, product quality obtained the promotion of essence, while output increased 40%, achieves
Good effect.
Summary of the invention
The purpose of the invention is to realize to carry out controllable fast cooling to open type circular furnace hopper, reduces product and go out
Furnace temperature improves furnace chamber and operates utilization efficiency, provides a kind of open-type ring-type roasting furnace Intelligent forced cooling device.
To achieve the purpose of the present invention the technical solution adopted is that:
A kind of open-type ring-type roasting furnace Intelligent forced cooling device, including Communicating device, connection mouth, collect air hose；Furnace chamber
Three faces, which are equipped with, collects air hose, collects and is equipped with multiple connection mouths according to furnace chamber on air hose, Communicating device is linked by connection mouth to be collected
Air hose, connection mouth are equipped with watertight sealing cover；Communicating device is set to above furnace chamber, is connected to by six quirks with furnace chamber, in quirk
It is equipped with gate valve；Collect air hose to connect by pipeline with high temperature draught fan.
The beneficial effects of the present invention are:
1, when former natural cooling, Φ 600mm or more is big, and specification ultra high power connector needs 18 days from ceasing fire to coming out of the stove, and answers
After the Intelligent forced cooling device, cooling rate is accelerated, only needs 9 days from ceasing fire to coming out of the stove, cooling time shortens 50%.
2, after using the Intelligent forced cooling device, after cooling time shortens, cooling shared stove drops to 4 by 7, rises
Temperature operation furnace chamber increases to 7.5 by 5, and yield increases by 50%.
3, cooling rate is automatically controlled using the Intelligent forced cooling device, can be controlled in 3.5 DEG C/h, product tapping temperature
Control 350--400 DEG C.Product tapping temperature reaches 500 DEG C when former natural cooling, is easy to produce stress when producing in winter and splits
Line, in the processing of rear process high temperature graphitization, Expanding of stress crack leads to waste product, and rejection rate reaches 5.5% or so.Reduction is come out of the stove
After temperature, winter production Shi Hou process high temperature graphitization waste product caused by unstressed crack propagation when handling.
4, open-type ring-type roasting furnace Intelligent forced cooling device of the present invention belongs to domestic initiation, to hyperfine structure, thin knot
Structure, middle fine texture special graphite, after baking tapping temperature are required to be lower than 200 DEG C, be acted on more prominent.
5, open-type ring-type roasting furnace Intelligent forced cooling device of the present invention is reliable for operation, practical, high-efficient, energy band
Carry out good economic benefits.
Detailed description of the invention
Fig. 1 is structure chart of the invention.
Fig. 2 is application drawing of the invention.
Specific embodiment
