Combined Development of High Performing Ladle Slide Gate Refractory and New Generation Ladle Slide Gate Mechanism to Maximise Benefits to Customers
Author: Samrat Sen
Abstract: Slide gate mechanisms are a well-established technology used on ladles in steel making facilities to provide safe operation during flow control of molten metal. Within the refractory stack-up of such mechanism, slide gate plates are subjected to more rigorous wear because of direct steel impingement and frequent throttling. This often limits the plate life, which causes additional downtime of the ladle. Keeping safety as the key attribute, it is therefore important to prolong the life of plates to ensure that ladle cycling is least interrupted. This is also key to reducing energy consumption, as ladles require re-heating to compensate for heat losses due to frequent holding in the make-up area. Furthermore, keeping ladles hot and reducing the extent of thermal cycling has a positive impact on the life of refractory linings, which in turn increases the campaign length and improves operational efficiency. Our extensive research has shown that there is a strong influence of the mechanism design on the refractory performance. Our vast experience in the field also validates the necessity for a combined approach in which both refractory and mechanism are developed together with the common objective of enhancing operational efficiency. Vesuvius R&D has developed a series of new designs and materials to further augment the offerings beyond addressing fundamental needs. The main objective was to develop a superior, reliable slide gate refractory composition that can be combined with an FEA-optimized shape in a mechanism that is designed to maximize contact area around the throttling zone. The refractory composition has been carefully tailored to offer strong throttle path integrity to prolong service life. The mechanism on the other hand has been developed to maximize safety by adding new features like infiltration inhibitors, fail-safe refractory installation as well as a force balancing concept with multiple springs.

Long Steel Casting with flexible System for Open and Shrouded Stream"
Author: Filipe Fabri
Abstract: The CNC Shrouded* is a tundish flow control system that allows the cast of long products in both open or shrouded stream from tundish to the mold. This allows steel of higher quality to be cast by protecting the stream from the re-oxidation from atmosphere as well as the usage of flux powder as lubricant, which also improves quality in terms of surface and thermal exchange with the mold. The trials were conducted to validate the proposition and evaluate the differences in terms of quality, considering surface of the billet, and as a second step, chemical analysis of samples. The preliminary results have proven the system improves significantly the quality, by having a much better surface quality as well as no re-oxidation, while being of simple usage operationally and of lower cost compared to other systems where there is flow control, such as tundish slide gate or stopper and submerged entry nozzle.

New Corrosion Test Method for Purging Refractory Ceramic
Author: Quentin Robinson, Mark Snyder, Phiip Hunger
Abstract: A new method was developed for corrosion testing of refractory materials used for argon purging in steel ladles, including the next generation OptiClean* and OptiFlow* purge plugs. The OptiClean*, and other purge plugs of this design type, incorporate a porous element to deliver argon to the ladle. “Directional” purge plugs, like OptiFlow™, use slots formed within a castable refractory to deliver argon to the ladle. A significantly improved erosion resistance was measured for the OptiClean* purge plugs compared to other commercially available purge plugs. This new test uses a purge plug, which is inserted into the bottom of a “pony ladle” with a capacity of 250 kg. Argon, or other gases, is purged through this plug into a bath of molten metal within the ladle. After gas purging, the ladle is emptied of molten metal. In some variations of the corrosion test the hot face of the purge plug is cleaned with an oxygen lance. The process of purging and lancing is repeated multiple times to mimic how a purge plug is used in steel mills or foundries. Conditions during the purging and lancing procedure are kept as constant as possible and molten metal temperature and quantity as well as argon gas flow and pressure are tightly controlled. After evaluating various purge plugs and test conditions, the purge plugs were analyzed for rates of corrosion and steel penetration. In an attempt to understand the mechanisms of erosion and steel penetration, these findings were correlated with the specific boundary conditions during the test. The results of this study and the potential of this new test method will be presented in this paper.

Increasing safety, operation efficiency and process reliability: Implementation of robotized tundish operations at Ternium Brasil
Author: V. Cunha Aranda, L. Mascarenhas Fernandes, E. Hernandez Duarte, W. Junior Correa, L. Martins Demuner, V. Cunha Aranda, F. Lourenço, V. Sinhorely Oliveira
Abstract: During manual tundish operations like temperature measurement, sampling, powder application and ladle shroud manipulation, the operator is exposed to heat, dust, physical exertion, and inherent danger from tundish reactions or ladle scull. Even though working in this environment, important operational tasks have to be performed in order to guarantee process stability and product quality. By implementing robotized tundish operations using two robots, a major increase in safety, operation efficiency and process reliability could be achieved. The present work gives a detailed overview of the project layout, its components, features and operational performance.
