Embodiment Construction

[0033] In this embodiment, the large blade (300 mm, weighing 2500 grams) of a 5000 series gas turbine is selected as the research object, and the research work is carried out. The material of the blade is directionally solidified superalloy GTD-111. Figure 1 shows a photo of the comparison of the shape and size of the aeroengine and the selected industrial gas turbine blades.

[0034] The present invention not only completes the research on the directional crystallization process of large blades, but also develops large blades with directional crystallization during the development process of the gas turbine blade directional crystallization process, as shown in FIG. 2 . At the same time, a new type of blade with single crystal and directional compound crystal has been successfully developed. The blade is composed of two crystal forms: oriented columnar crystals in the middle of the blade, and single crystals with a certain width (20-30 mm in this embodiment) at the inlet and ...

Abstract

A monocrystal and orientational cylindrical crystal combined blade used for gas turbine features that its middle region is orientational cylindrical crystals and its gas inlet and outlet edges have monocrystal form. Its manufacture method includes such steps as installing a composite crystallizer to the crystallizer of orientational crystallizing furnace, smelting by 100-150 of overheat, regulating the temp of mould heater to 1500-1530 deg.C for upper region and 1550-1580 deg.C for lower region, casting, and moving mould downward at 5-7 mm / S.

Description

technical field [0001] The invention belongs to the category of high-temperature alloy precision casting, new materials and new technology fields, and specifically relates to a novel single-crystal and directional columnar-crystal compound crystallization blade and its manufacturing technology, which are used to develop and produce various types of materials and blades for directional solidification of high-temperature alloys . Background technique [0002] Energy is the driving force of national economic construction. The research and development of high-performance gas turbines is an ideal power system required for sustainable development. All developed countries attach great importance to the research and development of gas turbines as a priority development strategy of science and technology, and have received key and rapid development. develop. In order to realize my country's energy sustainable development strategy, the country's energy policy has also made important ...
