The walking beam furnace (WBF) plays a critical role in a steel production factory, and has complex nonlinear dynamic behaviour. Thus, using the conventional physical principles to build a model of the process leads to a time-consuming modeling procedure and when the number of operating set-points in walking beam furnace increases the conventional modeling problem difficultly will be solved, in...

This study aims to identify factors that result in employees’ absenteeism in an organization, which may help the company manager to develope and identify attitudes of employees for minimising absenteeism. Data was collected from 100 steel manufacturing firm organizations adopting random or chance sampling method. The data was subjected to simple percentage analysis, for demographic variables an...

The paper deals with a removable steel inner gate which was designed to separate two parts of a dry dock of about 70 m in width and 380 m in length. The gate allows for independent assembly of ship structures in the two separated parts of the dock. The fore part of the dock can be flooded while the after part is dry. The gate was designed by IDEK Company Ltd in 2011 and it was soon constructed ...

Kobe Steel's history of pelletizing plants began when the company built a plant at its Kobe Works in 1966. This paper introduces the history of pelletizing plants, including process outlines and the latest achievements in the construction of plants overseas. In the past, plant owners had focused mainly on the quality of the product pellets and plant equipment, as well as the cost of the plants....

The present paper presents the algorithmic solution, based on an Ant System metaheuristic, of an industrial production–inventory problem in a steel continuous-casting plant. The model proposed is based on an objective function, the aim of which is to find the most profitable production schedule of the steel billets. Furthermore, the model takes into account the relevant parameters of the finite...

Abstract—The reheating furnace is used to reheat the steel slabs before the hot-rolling process. The supported system includes the stationary/moving beams, and the skid buttons which block some thermal radiation transmitted to the bottom of the slabs. Therefore, it is important to analyze the steel slab temperature distribution during the heating period. A three-dimensional mathematical transie...
