K-means algorithm is widely used in spatial clustering. It takes the mean value of each cluster centroid as Heuristic information, so it has some disadvantages: sensitive to initial and instability. The improved clustering referred best centriod which searched during optimization centroid. That increased searching probability around stability algorithm. experiment on two groups representative dataset proved that performs better global less
Precise knowledge of the heat transfer in a reheating furnace is important for optimizing slab production process. In present work, new comprehensive CFD (Computational Fluid Dynamics) model simulating gas flow, combustion and roller-hearth with radiant tubes was developed. model, dynamic heating process performed based on steady-state phase furnace. The movement slabs achieved by mesh. were coupled into whole indirect tubes. temperature predicted showed good agreement experimental results...
This study investigates microstructure, hydrogen diffusion properties, and stress corrosion cracking (SCC) behavior of Q345R steel subject to pre-applied strains 1%, 3%, 5%. The relationship between microstructure SCC susceptibility in hydrofluoric acid (HF) vapor is examined. It found that pre-strain cannot change the but increases dislocation density. increasing sensitivity HF associated with density induced by pre-strain. With pre-strain, reversible trap increase, interaction accelerates...
The dynamic recrystallization (DRX) behavior of Inconel 718 superalloy containing second phase particles (δ phase) was investigated through isothermal compression deformation tests under the temperatures 960 °C–1000 °C and strain rates 0.01, 0.1, 1 s−1. A developed cellular automaton (CA) model established to describe DRX process, considering ellipsoid particle effects stimulated nucleation pinning grain boundary mobility. comparisons average size evolution kinetics were carried out between...
The requirement of improving efficiency and performance leads to the continuous development furnaces burners. For this purpose, it is necessary establish a model suitable for industrial production adjust according demand. In paper, comprehensive numerical developed characterize combustion, heat transfer, slab heating in an indirect reheating furnace with pulse combustion. To realize combustion process, control approach based on user-defined function (UDF) was proposed radiant tube burner...
