Description
Technical field
The present invention relates to aero-engines and combustion gas steam turbine field, in particular to a kind of to process flame using annular forging piece
The process of cylinder floating wall tile fragment.
Background technique
Floating wall is one of very important part in engine chamber, is generally assemblied in burner inner liner inner wall outside and outer
On the inside of wall, for separating high-temperature fuel gas and the inside and outside wall of burner inner liner, cooling air circulation is formed between burner inner liner and floating wall
Road reduces flame tube wall temperature, and floating wall is generally composed of several entirety in the floating wall tile fragment of arc-shaped, floating wall watt
Several connecting studs, positioning column etc. are provided on block.
Currently, in aero-engine or gas turbine field, it is lasting between floating wall tile fragment and burner inner liner in order to guarantee
It is stably connected with, is unsuitable between connecting stud, positioning column on floating wall tile fragment and the arcwall face of floating wall tile fragment using assembling
The structure of formula, is generally used single-piece integral casting forming, and one-step casting forms connecting stud, positioning column on floating wall tile fragment
Deng, then pass through the processing that several cooling holes thereon are completed in certain machining, still, due to the curved wall of floating wall tile fragment
Generally there was only the thickness of 1-2mm, is affected in casting process by metal fluidity, qualification rate is lower, and casting obtained is normal
It will appear the casting metallurgical imperfection such as loose, shrinkage cavity, hole, lead to obtained floating wall shoe shape size distortion, surface
Roughness is not up to standard, metallurgical quality is unstable, and metallurgical quality of cast is unstable, is also easy to cause combustion chamber flame drum that can not hold
Work stable long.For aero-engine or gas turbine field, the connecting stud of floating wall tile fragment and the position of positioning column
Degree of setting also will have a direct impact on the overall performance of aero-engine or gas turbine, so, in scientific research and development or batch production boat
When empty engine or gas turbine, floating wall tile fragment connecting stud also have to be improved by the way of hot investment casting and is determined
The position degree of position column so causes the whole preparation cost height of floating wall tile fragment, period long, and can still have above-mentioned casting
