    • Avaliação de aditivos poliméricos e cerâmicos para a otimização microestrutural de refratários semi-isolantes 

      Farias, Thiago Wisley Barbosa de (Universidade Federal de São Carlos, UFSCar, Programa de Pós-Graduação em Ciência e Engenharia de Materiais - PPGCEM, Câmpus São Carlos, 21/07/2023)
      Macroporous insulating refractories have been extensively investigated due to their low thermal conductivity, low density, and non-toxicity compared to fibrous ceramic insulators. However, there are still challenges in ...

    • Cura de refratários à base de MgO via micro-ondas contendo, ou não, fontes de carbono 

      Ceribelli, Gabriel Arantes (Universidade Federal de São Carlos, UFSCar, , Câmpus São Carlos, 21/03/2023)
      Curing is an essential process for the manufacture and development of refractory materials and is now largely carried out by heating at relatively low temperatures compared to the working temperature for the material, with ...

    • Uso de materiais refratários recuperados em concretos para canais de corrida 

      Gomes, Pedro Henrique (Universidade Federal de São Carlos, UFSCar, , Câmpus São Carlos, 04/04/2022)
      In order to achieve a sustainable production, in a sector where the demand for natural raw materials is very high worldwide, this project aimed to explore the feasibility of increasing the addition of recovered materials ...

    • Trincas em sedes de plugue para panelas de aço: estudo de caso em unidade industrial 

      Ribeiro, Gabriela Bugni (Universidade Federal de São Carlos, UFSCar, , Câmpus São Carlos, 22/11/2022)
      Purging blocks are important components located in the bottom of Steel Ladles. Its main objective is to protect and connect the ladle and the plug, throughout inert gas, usually argon, is injected into the liquid metal ...

    • Desenvolvimento de cerâmicas refratárias engenheiradas densas e porosas 

      Pelissari, Pedro Ivo Batistel Galiote Brossi (Universidade Federal de São Carlos, UFSCar, Programa de Pós-Graduação em Ciência e Engenharia de Materiais - PPGCEM, Câmpus São Carlos, 04/09/2019)
      High temperature processes are of great importance as they are widely applied in the manufacture of commodities, consumer goods and advanced materials. For these processes to be possible, the thermal environment in which ...

    • Avaliação dos modelos numéricos para a simulação da secagem de concretos refratários 

      Moreira, Murilo Henrique (Universidade Federal de São Carlos, UFSCar, Programa de Pós-Graduação em Ciência e Engenharia de Materiais - PPGCEM, Câmpus São Carlos, 25/02/2021)
      The drying of hydraulic bonded monolithic refractories is the slowest stage of their application process. Problems related to the control of such a procedure result in cracks, spalling and even, in extreme cases, explosions ...
