Notice of RetractionNumerical Simulation of Oil Steel Pipe in Induction Heat Treatment Process
With the rapid development of the oil industry-level demand for steel, the performance of oil steel pipe has put forward higher requirements. Induction heat treatment of steel pipe can improve performance and save cost, so it has been widely used in the steel pipe manufacturing industry. In order to reduce the number of trial-error procedures in plant which usually are long and costly, numerical simulation has been revealed as an important tool in designing the induction heating system. In this paper, the steel pipe temperature distribution in induction heat treatment is simulated considering the material properties. It is shown that the simulation results of the object temperature in good agreement with the different technology demands, which can provide useful information to optimize the whole induction heating process.
Numerical model approaches for in-line strip induction heating
This paper describes the experience of the authors in numerical modeling of induction system with movable strips. Several numerical approaches have been applied to predict a “quasi” steady-state thermal fields which naturally describes the temperature field in the strip when the induction heating applied. The approaches have been analyzed to prove their advantages and shortcomings to be applied for coupled electromagnetic and thermal numerical models of induction heating. The approaches are illustrated with examples of two concepts of the induction heating design which are widely utilized in in-line strip heating.
Numerical analysis of coupled physics for induction heating of movable workpieces
This paper describes the experience of the authors in numerical modelling of induction heating systems with movable workpieces. Four different numerical approaches have been applied and tested to predict “quasi” steady-state or transient thermal field in the workpieces of different shape and kind of movement. All the approaches have been analysed to prove their advantages and inconveniences to be used in coupled electromagnetic and thermal numerical models of induction heating systems. Each approach is explained by an example from research practice of the authors.
