Abstract
An experimental investigation has been carried out to analyse different mould section sizes to measure the meniscus fluctuation by varying different liquid flow rates and different submerged entry nozzle port angles, i.e., 0° port angles, 15° downward and 15° upward port angles. The terms of maximum surface wave fluctuation and standard deviation have been analysed for the above mentioned parameters. It was observed that a submerged entry nozzle with 0° port was found to be superior when it was compared with a 15° downward and 15° upward port nozzle. By conducting an experiment, it was observed that as the water flow rate increased, the maximum wave amplitude was found to be increasing, which results in more turbulence. Different mould section sizes were analysed to provide background information to the steelmaker to analyse the behaviour of fluid flow pattern. The operating parameters of the result obtained from the present setup were compared with the published literature, and a scale down of slab moulds can be justifiedregarding the rough flow pattern in the mould but can lack accuracy. The reason behind this statement is that the integral length scales of the turbulent flow between scaled down and full scale models can be different. Therefore, details of the flow pattern can become great differences between both types of models.
Highlights
Over five decades, a large number of investigations have been carried out on various aspects of the continuous casting process
The first study was conducted on the straight bore nozzle and it studied the behaviour of the fluid flow pattern in the submerged entry nozzle with the help of a stopper rod and the slide gate control system
Ultrasonic, inductive techniques, and X-ray radioscopy were employed for the quantification of flow or the visualizations of two-phase flow regimes occurring in the submerged entry nozzle and the mould [21]
Summary
A large number of investigations have been carried out on various aspects of the continuous casting process. Ultrasonic, inductive techniques, and X-ray radioscopy were employed for the quantification of flow or the visualizations of two-phase flow regimes occurring in the submerged entry nozzle and the mould [21] In this current study, a laboratory design of a continuous casing machine has been modelized and constructed toward implementation of an experiment under different variables like water flow rate, different mould section size, and different submerged entry nozzle port angle. Analysis provides persistent investigation results because laboratory design is not affected by the type and composition of the produce In this experiment, the chief objectives are (i) performing an experiment to measure the meniscus fluctuation under different mould section size, and different submerged entry nozzle port angle under different operating conditions, and (ii) to conduct a comparative analysis of the various parameters for the proposed system
