Abstract
The invention relates to a turbine mould shell structure. The structure is characterized by including, successively from interior to exterior, a zircon surface layer (1), a first mullite sand layer (2), a second mullite sand layer (3), a third mullite sand layer (4), a fourth mullite sand layer (5) and a vermiculite layer (6), wherein mullite sand in the first mullite sand layer (2) is 60-80 in meshes, the mullite sand in the second mullite sand layer (3) is 30-60 in meshes, the mullite sand in the third mullite sand layer (4) is 30-60 in meshes and the mullite sand in the fourth mullite sand layer (5) is 16-30 in meshes. By means of the special structure, a shell mould shell has a high-strength performance and a high thermal-insulation performance. A turbine produced with the mould shell is good in quality.
Description
Technical field
The present invention relates to a kind of turbine formwork structure, belong to turbine manufacturing technology field.
Background technology
In turbine manufacture process, need to become turbine formwork at wax-pattern outer surface hull shape processed.Traditional turbine form strength is lower, and heat-insulating property is poor, makes the turbine of production second-rate.Therefore seek a kind of high strength, high heat preservation performance, make the good turbine formwork of the turbine quality structure of production particularly important.
Summary of the invention
The object of the invention is to overcome above-mentioned deficiency, a kind of high strength, high heat preservation performance are provided, make the good turbine formwork of the turbine quality structure of producing.
The object of the present invention is achieved like this:
A kind of turbine formwork structure, it is characterized in that it comprises that the zircon surface layer, first setting gradually from the inside to the outside does not come layer of sand, second not come layer of sand, the 3rd not come layer of sand, the 4th not come layer of sand and vermiculite layers, described first not carry out the sand that do not come of layer of sand be 60 ~ 80 orders, described second not carry out the sand that do not come of layer of sand be 30 ~ 60 orders, the described the 3rd not carry out the sand that do not come of layer of sand be 30 ~ 60 orders, and the described the 4th not carry out the sand that do not come of layer of sand be 16 ~ 30 orders.
Compared with prior art, the invention has the beneficial effects as follows:
The present invention adopts this special structure, makes turbine formwork have high strength, high heat preservation performance, and the turbine quality of production is better.
Accompanying drawing explanation
Fig. 1 is the structural representation of turbine formwork structure of the present invention.
Wherein:
Zircon surface layer 1
First does not carry out layer of sand 2
Second does not carry out layer of sand 3
The 3rd does not carry out layer of sand 4
The 4th does not carry out layer of sand 5
Vermiculite layers 6.
The specific embodiment
Referring to Fig. 1, a kind of turbine formwork structure the present invention relates to, it comprises that the zircon surface layer 1, first setting gradually from the inside to the outside does not come layer of sand 2, second not come layer of sand 3, the 3rd not come layer of sand 4, the 4th not come layer of sand 5 and vermiculite layers 6, described first not carry out the sand that do not come of layer of sand 2 be 60 ~ 80 orders, described second not carry out the sand that do not come of layer of sand 3 be 30 ~ 60 orders, the described the 3rd not carry out the sand that do not come of layer of sand 4 be 30 ~ 60 orders, and the described the 4th not carry out the sand that do not come of layer of sand 5 be 16 ~ 30 orders.
