Description
Technical field
The present invention relates to aluminum alloy wheel of vehicle manufacturing fields, specifically say, are related to a kind of aluminum alloy wheel of vehicle manufacture
Waste heat integrated utilization system.
Background technique
Aluminum alloy wheel of vehicle manufacture is related to multiple processes such as melting, casting, heat treatment, machining, surface coating, needs
Consume a large amount of electric & gas；Especially melting, casting, heat treatment, surface coat the link that link is all high energy consumption, because
Generally the sector belongs to the industry of high investment, high energy consumption for this.China has become the first big aluminum wheel of vehicle in the world at present
Manufacture and big export country, but whole manufacturing technology locates medium level in the world, and wherein energy utilization rate, green manufacturing are horizontal
Lag significantly behind World Developed Countries；And not only energy utilization rate is low for China's aluminum vehicle wheel industry, and the waste heat of production process is basic
It is direct emission, does not carry out secondary use, this not only causes energy waste, production cost remains high, but also causes
Influence to environment.Such as in fusion process, smelting furnace feeding port and exhaust port area temperature are up to 250~350 DEG C, press
According to current production technology, which be directly discharged in atmosphere；In casting process, still there are 300~380 DEG C after casting demoulding
Temperature, production technology is that casting is cooled to room temperature by immersion at present, circulated again after then boring riser to heat treatment procedure, warp
It calculates in this process, per kilogram aluminium casting will discharge about 264KJ heat, produce the medium-sized enterprise of 500,000 aluminum vehicle wheels per year with one
Industry calculates, and daily output aluminium casting 25000Kg, the i.e. process will discharge 6600000KJ heat, is equivalent to 1833 degree of electricity and generates
Heat, according to current technique, which exhausts during entire circulation；During heat treatment, work is produced at present
Skill is: solid solution -- quenching -- timeliness, wherein quenching be will be dissolved carried out in 70~90 DEG C of water up to 535 DEG C of casting it is cold
But, which not only needs to be continuously replenished a large amount of cooling water and cools down to casting, but also the casting of high temperature can release greatly
The thermal energy of amount will discharge 900000KJ heat, quite if quenched after being computed the casting solid solution for having 25000Kg daily
In the thermal energy that 2750 degree of electricity generate, production technology is that the quenched hot water is directly discharged to sewer, hot water in industry at present
It is wasted in vain.As it can be seen that China's aluminum-alloy wheel industry smelting furnace waste heat is directly discharged in atmosphere at present, casting process demoulding
Then afterheat of casting afterwards bores riser because first carrying out being cooled to room temperature, waste heat does not also utilize；Heat treatment process a large amount of 70~
90 DEG C of quenching water is directly discharged to sewer and is not also utilized.
It is me that China, which becomes the first big aluminum wheel of vehicle manufacture and big export country, aluminum wheel of vehicle in the world for continuous ten years,
A few advantageous auto Parts Industry of state, but the characteristics of the industry current extensive production still clearly,
Aluminum wheel of vehicle output in China's is about 1.5 hundred million every year at present, accounts for about the 55% of Gross World Product, according to current the sector
Production method, just have in melting, casting, heat treatment and be equivalent to 3.24 hundred million degree electric waste heats and be not fully used.With
Energy conservation and environmental protection cry grows to even greater heights, especially in the world to the highest attention of greenhouse gas emission, as high energy consumption industry
The manufacture of aluminum wheel of vehicle constantly reduces the production cost of enterprise there is an urgent need to carry out energy-saving and emission-reduction by technological transformation,
Enhance the competitiveness of international market.Simultaneously because China's aluminum wheel of vehicle outlet international market is more and more, international community is to me
The energy conservation and environmental protection of state's automobile product is also increasingly paid close attention to, therefore the research staff of domestic aluminum vehicle wheel industry is implementing aluminum vehicle wheel green
In the research process of manufacturing technology, manufacturing process waste heat secondary use is classified as to always the object of emphasis tackling key problem.
Summary of the invention
The purpose of the present invention is in the manufacturing process of current aluminum wheel of vehicle, especially melting, casting, heat treatment process
Energy waste, environmental pollution, increased costs caused by a large amount of waste heat does not utilize provide a kind of aluminum alloy wheel of vehicle manufacture
Waste heat integrated utilization system.
Realizing the scheme of the above technology is: a kind of aluminum alloy wheel of vehicle manufactures waste heat integrated utilization system, the system by
