Description
Technical field
The present invention relates to a kind of parts of large aluminum alloy Equipment for Heating Processing, especially to carrying out quenching technical after solid solution, Ageing Treatment, adopt fire door to be positioned at the two blow-on door mechanism of the heat-treatment furnace of bottom.
Background technology
Along with the development of non-ferrous metals industry and the progress of non-ferrous metal application technology, aluminium alloy is unique and superior performance with it, in the industries such as the industrial departments such as aviation, automobile, motorcycle, light industry and building, five metals, packaging for foodstuff and medicine equipment, obtains a wide range of applications.Therefore, the demand of aluminum alloy heat treatment facility is constantly increased, meanwhile, more and more high to the quality requirement of heat-treatment furnace product.
Aluminum alloy heat is processed and has been developed into an important component part in metal heat treatmet field.The heat treated object of aluminium alloy, being summed up is mainly to improve intensity and hardness, eliminates the internal stress producing in pressure processing process, makes it obtain uniform composition, tissue and performance.
Aluminium alloy heat-treating methods is a lot, and basic treated forms has quenching, timeliness and annealing etc.The latter belongs to softening processing, and object is obtain stable and organize uniformly and good working plasticity.The former claims again solution treatment.
As everyone knows, solution heat treatment is the Technology for Heating Processing that improves intensity of aluminum alloy, and its process comprises quenches and timeliness.
The process for quenching of aluminium alloy, is all generally that the workpiece that will quench is placed in the more uniform heating furnace of temperature, it is heated to the hardening heat of regulation, and is incubated a period of time at this temperature, and the tissue of alloy is changed.Some can dissolve in the alloying element (playing invigoration effect) in αsolidsolution, and its solubility is along with temperature improves and increases.Then workpiece is promptly soaked in people's water coolingly, the alloy structure during high temperature is at room temperature fixed up with the form of supersaturated solid solution (rise induration), and this is all processes quenching.
Key problem in technology problem of aluminum alloy quenching is that workpiece quenching transfer time must be very short, to avoid quench front its part and even bulk temperature decline.
Workpiece enters quenching tank interval from coming out of the stove to is called quenching shift time, in workpiece transfer process, workpiece temperature declines and causes solid solution generation decomposed, separate out thick loose phase, produce microstructure segregation, thereby reduce ageing strengthening effect, research according to one's analysis, 5 ° of C of temperature decline after workpiece is come out of the stove, can cause strength decreased 20%.Customary quenching conversion time is 7s～25s, specifically depending on workpiece size thickness.
The heat-treatment furnace adopting at present, its fire door design unreasonable, the unidirectional design of opening the door makes its overlong time of opening the door.Like this, the Al-alloy parts in it after Overheating Treatment, just needs the long period just can deliver in the quenching tank of subsequent technique.And if the part turnaround time is long, be easy to the treatment effect of the Technology for Heating Processing of carrying out before having influence on part.
Therefore, a kind of novel heat-treatment furnace fire door mechanism of the necessary design of industry, overcomes defect of the prior art.
