Design analysis of a hot strip mill runout table bed under ANSYS workbench

A structural analysis has been performed on the setup of a spray cooling system for a model of a hot strip mill. The objective was to design a run out table (ROT) whose length is reduced for a spray cooling system. The setup consists of a bed (ROT) whose height can be adjusted as desired, and a carriage which would be carrying the hot plate, moving along the bed, for experimentation. The CAD modelling was done in CATIA and the analysis was performed in ANSYS Workbench. A prototype of the whole setup was built from the virtual model and was controlled using products from National Instrument Corporation (NI). The analysis is being conducted for the design optimization of the entire setup and its safety.

Over Time

When dealing with time continuous processes, the discovered association rules may change significantly over time. This often reflects a change in the process as well. Therefore, two questions arise: What kind of deviation occurs in the association rules over time, and how could these temporal rules be presented efficiently? To address this problem of representation, we propose a method of visualizing temporal association rules in a virtual model with interactive exploration. The presentation form is a three-dimensional correlation matrix, and the visualization methods used are brushing and glyphs. Interactive functions used for displaying rule attributes and exploring temporal rules are implemented by utilizing Virtual Reality Modeling Language v2 mechanisms. Furthermore, to give a direction of rule potential for the user, the rule statistical interestingness is evaluated on the basis of combining weighted characteristics of rule and rule matrix. A constraint-based association rule mining tool which creates the virtual model as an output is presented, including the most relevant experiences from the development of the tool. The applicability of the overall approach has been verified by using the developed tool for data mining on a hot strip mill of a steel plant.

Fast Cooling

With advanced high-strength steels and high value-added steels development, it is very important to improve the cooling capacity and cooling intensity of the run out table cooling system. The key technology is to break the vapor between hot strip and cold water and to increase the direct contact area. In order to realize the ultra fast cooling, Laboratory research such as jet nozzle type selection and diameter of nozzle decision and factory tests such as cooling capacity testing have been done. Experiment results show that circular nozzle has bigger hitting power than fan-type nozzle. However, drainage capacity caused by fan-type nozzle is better than that by circular nozzle. In addition, nozzles of different diameters have nearly the same cooling capacity despite of the very different water flow. Cooling power testing results show that cooling capacity is enhanced with pressure increasing and with speed decreasing.
