Continuous casting of steel : fundamental principles and practice

The aim of this study was to obtain a predictive model able to perform an early detection of central segregation severity in continuous cast steel slabs. Segregation in steel cast products is an internal defect that can be very harmful when slabs are rolled in heavy plate mills. In this research work, the central segregation was studied with success using the data mining methodology based on multivariate adaptive regression splines MARS technique. For this purpose, the most important physical-chemical parameters are considered. The results of the present study are two-fold. In the first place, the significance of each physical-chemical variable on the segregation is presented through the model. Second, a model for forecasting segregation is obtained.

1. Introduction

Free delivery on qualified orders. Several different types of commercial continuous casting processes exist Fig. Vertical machines cast aluminum and a few special alloys. Curved machines are used for steel, which can tolerate some bending and or unbending of the solidifying strand. Steel from the electric or basic oxygen furnace is tapped into a ladle and taken to the continuous casting machine.

The key control parameter of continuous casting is matching the flow of liquid steel into the mold with the withdrawal speed of the strand out of the mold. The control of flow rates is accomplished by the tundish, a small, refractory-lined distributer that is placed over the mold and that receives steel from the furnace ladle see figure. Withdrawal speed is controlled by driven rolls, which contact the strand at a point where it has already developed a thick, solidified shell. Feeding of the caster mold from the tundish is controlled by a stopper rod or a sliding gate similar to the equipment used in ladles see above Secondary steelmaking: The ladle: Tapping. Shielding can be accomplished by pouring steel through refractory tubes that are immersed in the steel or through wide sleeves that are pressurized with argon.
