Abstract

The invention provides a machining technology for an X12CrMoWVNbN10 fixed blade ring forging and belongs to the field of forging technologies. The machining technology for the X12CrMoWVNbN10 fixed blade ring forging comprises the specific steps of raw material purchasing control, forging control, heat treatment, upsetting, machining treatment, size inspection and identification, an extension testexperiment, an impact test experiment and sealing up for safekeeping and warehousing. According to the machining technology, unique forging treatment and heat treatment are adopted, when compaction forging is conducted on the X12CrMoWVNbN10 fixed blade ring forging, a blank can be fully compacted, the purpose of refining grains is achieved, the process method is mature, and the problems that the forging is easy to break, the production time is too long, and the working efficiency is low are solved effectively.

Description

technical field [0001] The invention belongs to the field of forging technology, and in particular relates to a processing technology of X12CrMoWVNbN10 stationary vane ring forging. Background technique [0002] The F-class gas turbine 680 unit is a new product developed by the introduction of Siemens gas turbine technology in my country. Among them, the stator blade rings of two materials, S235JRG3 and 16Mo3, must withstand complex and alternating loads for a long time in a high-temperature and high-pressure operating environment. The production and manufacturing process of the parts has no precedent in China and can be referred to; the prior art patent announcement number 201110252203.6 discloses the manufacturing method of the F-class gas turbine vane ring rough forging. Heating, billet opening and forging deformation treatment: the initial forging temperature is 1220°C, the final forging temperature is 850°C, ring rolling for forgings: control the forging billet temperatur...
