The invention relates to a high-strength turbine mould shell structure which 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), a fifth mullite sand layer (6) and a vermiculite layer (7), 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, the mullite sand in the fourth mullite sand layer (5) is 16-30 in meshes, and the mullite sand in the fifth mullite sand layer (6) 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 [0001] The invention relates to a high-strength turbine formwork structure, which belongs to the technical field of turbine manufacturing. Background technique [0002] In the turbine manufacturing process, it is necessary to make a shell on the outer surface of the wax pattern to form a turbine mold shell. The traditional turbine formwork has low strength and poor thermal insulation performance, which makes the produced turbines of poor quality. Therefore, it is particularly important to seek a turbine formwork structure with high strength and high thermal insulation performance, so that the produced turbine quality is better. Contents of the invention [0003] The purpose of the present invention is to overcome the above disadvantages and provide a turbine formwork structure with high strength and high thermal insulation performance so that the quality of the produced turbine is better. [0004] The purpose of the present invention is achieved like this...
