Automation of industrial activities is one of the most essential needs in recent years since the operator has smaller role in the process. Creation of the various robotic systems in the different industries causes relaxing the operators from working in hard positions, increases the accuracy, efficiency and velocity in the process and decreases the wastage and price of product. In this paper, the study on melting station and continuous casting line in Mobarakeh Steel Complex is provided. The needs for elimination of difficulties and increasing the automation level of steel slabs casting line with checking the all stations from robotic and automation point of view for stations with the capability of automation system necessitates a suitable robotic system. In this case, selected robot should be able to support the velocity, accuracy, load capacity and other characteristics. Considering the sensitive conditions around the electric arc furnace (E.A.F), a suitable sampling robot with 3-degree freedom in which all three joints moves in revolute form (RRR) has been designed.
