Forging forming method of high-temperature alloy GH4169

Abstract

The invention relates to a forging forming method of a high-temperature alloy, in particular to a forging forming method of a high-temperature alloy GH4169. According to the technical scheme, the forging forming method of the high-temperature alloy GH4169 is characterized in that the process parameters of the method meet the requirements that the forging temperature ranges from 500 DEG C to 600 DEG C and the preheating temperature of a die ranges from 100 DEG C to 125 DEG C, the water-based graphite is used as a die chamber lubricant for the die, forging equipment is a hot die forging press, and the rated pressure of the hot die forging press is 1000 kN. According to the forging forming method of the high-temperature alloy GH4169, the forming temperature is reduced, and the surface oxidation of the forge piece is reduced, so that the surface quality of a forge piece is improved, the strength loss of the die is reduced, the precision of the die is guaranteed, the dimensional tolerance of the forge piece can reach the precision E-level, the mechanical machining allowance is reduced to be 1.5 mm on a single face, and the raw materials are saved.

Description

technical field [0001] The invention relates to a forging forming method of a superalloy, in particular to a forging forming method of a high temperature alloy GH4169. Background technique [0002] GH4169 is a nickel-based superalloy material commonly used in aviation products. Its traditional forging method is hot forging, and its forming temperature is 1150°C. Ordinary glass lubricants have little effect during high temperature forging, and cannot provide lubrication and protection. However, glass lubricants that can work are expensive, which greatly increases manufacturing costs. Therefore, GH4169 does not use lubrication during hot forging. agent. Under the forging forming temperature of 1150°C, the surface of the forging is severely oxidized, causing severe wear of the mold, and at the same time, the mold is annealed during the production process, which reduces the strength of the mold. The surface quality of the forging is poor, the mold is repaired frequently, and t...

Ordinary glass lubricants have little effect during high temperature forging, and cannot provide lubrication and protection. However, glass lubricants that can work are expensive, which greatly increases manufacturing costs. Therefore, GH4169 does not use lubrication during hot forging. agent

At the forging temperature of 1150°C, the surface of the forging is severely oxidized, causing serious wear of the die, and at the same time, the die is annealed during the production process, reducing the strength of the die

The surface quality of the forging is poor, the mold is repaired frequently, and the size fluctuates greatly. Therefore, the tolerance used for the forging is ordinary F-level.
