For the purpose of increasing capacity an Angang Strip Production (ASP) continuous caster and surface quality a medium-thin slab with mold sections 150 × (1020–1540) mm2, present work investigated influences submerged entry nozzle (SEN) structure main operating parameters on flow characteristic temperature distribution in by physical numerical simulations. The results showed that typical “doubl...

In many production processes real time information may be obtained from process control computers and other monitoring systems, but most existing scheduling models are unable to use this information to effectively influence scheduling decisions in real time. In this paper we develop a general framework for using real time information to improve scheduling decisions, which allows us to trade off...

The mold region of the continuous caster, the most widely used casting device used by the steel industry has been modeled through a combination of a steady-state heat transfer approach and a recently developed pareto-converging genetic algorithm (PCGA). Due to highly non-linear nature of the objective functions, as well as the constraints, locating the pareto-front was quite a challenging job i...

Over the years, considerable efforts have been made to study the performance of Submerged Entry Nozzle (SEN) and mould of continuous slab caster. Numerous physical and numerical modelling studies have already been carried out and reported in the literature to study the fluid flow behaviour inside the mould. Based on the extensive literature search, a summary of these is presented here. For the ...

We present an empirical study of process parameter tuning in industrial continuous casting of steel where the goal is to assure the highest possible quality of the cast steel through proper parameter setting. The process is assumed to be under steady-state conditions and the considered optimization task is to set 18 coolant flows in the caster secondary cooling zone to achieve the target surfac...

Electromagnetic fields have emerged as powerful tools for addressing current problems in thin slab continuous casting processes the iron and steel industry. Substantial studies been undertaken on fundamental effects of electromagnetic brakes (EMBr) strand stirring (SEMS). However, little attention has focused melt flow solidification a caster with simultaneous application an EMBr SEMS. The pres...

Purpose – This paper aims to provide a simple and cheap calibration method to improve the odometry accuracy and to present an alternative method for the control of the path produced by an already existed path planning method. Design/methodology/approach – Through the integration of systematic odometry errors the robot’s odometry parameters are estimated and through the replacement of a caster w...

A conventional twin-roll caster usually casts strips at a speed slower than 2 m/min and roll load greater kN/mm. vertical-type high-speed can cast aluminum alloy higher 10 smaller 550 N/mm due to the effect of large thermal conductivity copper rolls, compared with that steel rolls. However, properties an strip 140 30 are not clear. In this study, Al–5%Mg were loads 88 using caster. The effects ...

This paper reports on preliminary numerical experiments in optimizing coolant flows in continuous casting of steel with respect to multiple objectives. For this purpose, Differential Evolution for Multiobjective Optimization (DEMO) coupled with a reliable numerical simulator of the casting process was applied. The algorithm parameters were initially tuned to balance between the quality of the e...
