Embodiment Construction

[0017] The present invention will be further described below:

[0018] In the embodiment of the present invention, the size of the required annular GH105 superalloy forging is: φ670±5 (outer diameter)×590±5 (inner diameter)×51±4mm (height), and the superalloy forging has a thinner wall thickness (about 30mm ) ring forgings, the height is low (about 50mm), and the ratio of height to thickness is about 1.67, so the superalloy forgings are not easy to roll and expand directly. Rolling can only be carried out when the hole of the horse bar must be reamed to a certain extent (to ensure that the final deformation is 15%). According to the size of the annular GH105 superalloy forging, the blanking specification is determined as: φ365×52mm. In the embodiment of the present invention, the final forging temperature corresponding to the annular GH105 superalloy forging is set at 1010° C. to 990° C.

[0019] The blanks cut according to the specifications are covered with aluminum silica...

Abstract

The invention belongs to the technical field of GH105 high-temperature alloy forging and discloses a forging method of a circular GH105 high-temperature alloy forging. The method includes the steps of sheathing a blank; heating the sheathed blank; after heating, removing a sheath, and punching the blank; cooling the blank, and performing cutting and arc chamfering on the surface of an inner hole of the blank; performing sand blasting and grinding on the surface of the blank; sheathing the blank; heating the sheathed blank; after heating, removing the sheath, alternately performing double saddle forging and single end flattening on the blank until the size of the blank is in the range of set blank size; sheathing the blank and heating the sheathed blank; after heating, removing the sheath and performing ring rolling on the blank until the forging forms.

Description

technical field [0001] The invention belongs to the technical field of GH105 superalloy forging, and in particular relates to a forging method of an annular GH105 superalloy forging. Background technique [0002] GH105 alloy is a high-alloyed aging-strengthened nickel-based deformed superalloy with high strength, poor thermal processing performance and poor welding performance. The temperature is 750°C to 950°C. Due to the high degree of alloying of the alloy, high deformation resistance, narrow forging temperature range, and poor plasticity, it is easy to crack at the corners during forging. The cracks are generally 3mm-5mm wide and 7mm-10mm deep; It is also a problem in the forging process of GH105 material rings. The problem of uneven heating and coarse grains is generally solved by repeated grinding and increasing the number of forging fires, which undoubtedly increases the cost, and uneven heating and mixed crystals are not easy to solve. The smelting of raw materials...
