Abstract

REVESTIMENTO MONOLìTICO DE CONCRETO SEM CIMENTO à BASE DE SILICA COLOIDAL SOBRE ISOLAMENTO ESTRUTURAL EM FIBRA CERáMICA PARA FORNOS DE PELOTIZAçãO, PRINCIPALMENTE AS CãMARAS DE COMBUSTãO. Patente de Invenção para um inédito conceito de revestimento para câmaras de combustão industriais - mais especificamente para a produção de pelotas de minério de ferro - que foi desenvolvido para proporcionar uma isolação mais eficiente, resistente e económica devido ao aumento de sua vida útil e ao rápido tempo de montagem. é compreendido por uma camada de placas de isolação estrutural de fibra cerâmica denominada silplate (1) aplicada na zona inferior da câmara de combustão (2), e de fibra cerâmica BBM-5 (3) com alto teor de pureza e fibras policristalinas na zona superior, ambas recebendo a aplicação de tinta látex (4) para reduzir a absorção da água do concreto refratário sem cimento (5) também denominado sol-gel que utiliza sílica coloidal no lugar de água para se obter a consistência apropriada para a aplicação.MONOLYTIC CONCRETE COATING OF CONCRETE COLOID SILICA BASED ON CERAMIC FIBER STRUCTURAL INSULATION FOR PELLETING FURNACES, MAINLY COMBUSTION CHAMPS. Invention patent for an unprecedented coating concept for industrial combustion chambers - more specifically for the production of iron ore pellets - that was developed to provide more efficient, durable and economical insulation due to its extended life and fast assembly time. is comprised of a layer of ceramic fiber structural insulation plates called silplate (1) applied to the lower zone of the combustion chamber (2), and high purity BBM-5 (3) ceramic fiber and polycrystalline fibers in the zone. top, both receiving latex paint (4) to reduce water absorption of cementless refractory concrete (5) also called sol-gel which uses colloidal silica in place of water to obtain the proper consistency for application.
