AI Technical Summary

Technical Problem

The existing fixed normalizing process cannot adapt to the fluctuations in the chemical composition of raw materials in different furnaces, resulting in low-niobium materials being prone to over-burning and coarse grains, and high-vanadium materials being prone to under-burning and insufficient strength. Process adjustments rely on manual experience, leading to unstable quality of large wind turbine flanges.

Method used

By acquiring furnace composition data and utilizing thermodynamic calculations and classification judgment logic, the normalizing temperature of the wind power flange is dynamically adjusted to construct a temperature window, thereby achieving precise and automated control of each furnace and its own process.

Benefits of technology

It achieves precise temperature matching for materials from different furnaces, avoiding problems such as abnormal grain growth and incomplete dissolution of reinforcing phases, improving the pass rate of low-temperature impact toughness and strength, reducing reliance on human experience, and ensuring the standardization and quality reproducibility of the production process.

Abstract

The present application belongs to the technical field of large forging heat treatment manufacturing, and specifically relates to a method for dynamically regulating normalizing temperature of a wind power flange based on furnace number composition, comprising the following steps: obtaining furnace number composition data of a wind power flange raw material to be treated; and constructing a normalizing process temperature window; based on the core micro-alloy element content in the furnace number composition data, performing process robustness classification determination on the furnace number material to determine its behavior tendency of grain growth or strengthening phase dissolution at different temperatures; according to the result of process robustness classification determination, dynamically matching and locking the optimal normalizing temperature of the furnace number material in the normalizing process temperature window; and outputting the optimal normalizing temperature as a process instruction to a heat treatment execution unit. The present application realizes precise regulation and control of "one furnace one process", effectively suppresses grain coarsening of low niobium materials, and ensures sufficient dissolution of strengthening phases of high vanadium materials, thereby significantly improving the stability of grain size and mechanical properties of the wind power flange.
