Products for Deguisa
Deguisa manufactures and supplies concrete for the tundish roof lining in different qualities, designed to guarantee high performance of the refractory in a wide range of operating temperatures.
Deguisa has an extense catalogue of refractory concrete qualities, highlighting BRIO and TITAN families.
Refractory components for the protection of steel from oxidation reactions and other environmental contaminations in the transfer process from laddle to tundish and from tundish to continuous casting machine.
Due to the geometric diversity, large dimension and quality requirements because of the thermal shock and chemical attack, these pieces are manufactured by means of isostatically pressed processes in high performance alumina carbon.
The tundish is a container of large dimensions that receives the steel from the ladle prior to its introduction into the continuous casting machine.
Tundish are highly responsible facilities within the casting process of molten steel, because they are subjected to high temperatures continuously and failure of them involves not only the production sequence, but also the safety of the plant.
For this reason, Deguisa manufactures highly reliable products that guarantee the quality and purity of the steel produced as well as the integrity of the installation.
Applied in the existing joints between the different shaped refractory components present in the laddle, such as sliding gate systems and plugs for steel agitation.
The composition of each product allows adapting to different geometries and the operational needs of each plant, ensuring a proper seal.
| PRODUCT | APPLICATION |
| Sealplast | Sealing joints between plates and collector nozzle in sliding gate systems |
| Graphite mass | Sealing joints between nozzle and block |
| Seal-Chrome | Sealing joints between nozzle and block, and between plug and block |
Deguisa manufactures and supplies different types of refractory concretes to cover all types of applications in the steelworks.
The most common applications for the different concretes are the following:
Wellfiller sands for nozzle blocks with different chemical compositions and granulometric distribution in order to optimize the opening of the flow of steel for any geometry of installation or quality of cast steel.
Deguisa manufactures different sealing masses to fill the joints between the components of the refractory package used on the sliding valve system, among other applications.
The composition of each product allows adapting to different geometries and thicknesses of refractory joints and the operational needs of each client.
Refractory component installed in the bottom of the laddle either against brick or fixed by concrete through the central hole, it drives the flow of molten steel to the nozzle inserted in it.
Deguisa manufactures and supplies these components in a wide range of refractory qualities suitable for all types of operating conditions.
Component placed inside the block of the laddle, which drives the flow of steel inside the sliding valve mechanism.
Deguisa manufactures and designs nozzles for systems of all types of closing mechanisms present in the market *, in different qualities and manufacturing techniques to get the best performance in each installation.
* Mechanisms with Deguisa patent or out of patent.
Tubes or nozzles connected to the set of refractory plates that DRIVE the flow of steel to the Tundish or ingot mould directly or through the protection tube.
Deguisa designs and manufactures different geometries and qualities according to the needs of the client. Its modular assembly allows the use of refractory geometries and qualities independently of the rest of the components.
