Hercynite (FeAl2O4) was obtained by Arc Plasma Synthesis (APS) and thermally annealed at 1000 °C for 1, 24 and 36 h respectively, in air. The XRD measurements, that were conducted before and after the annealing, showed an evident alteration of the original hercynite under the influence of temperature and oxygen access.
Silicon Carbide Reticulated Porous Ceramics (SiC RPCs) with multi-layered struts were designed via polymer sponge replica technique together with vacuum infiltration of alumina slurry containing kyanite.
In this work, four alumina-magnesia, cement-bonded castables were tested at high temperature. Strength was determined by bending test at temperature ranging from room temperature to 1550 °C. As a reference, a high alumina castable was also investigated.
At end of October 2017, RHI Magnesita, which evolved from the merger of RHI AG and Magnesita Refratarios S.A., was for the first time traded in the premium segment on the London Stock Exchange. This merger to form the globally largest supplier of high-quality refractory products, systems and services brings together more than 14 000 employees in 35 main production plants as well as more than 70 sales offices. With a vertically integrated value creation chain from raw material to refractory product- and performance-oriented integrated solutions, RHI Magnesita serves 10 000 customers especially in the steel, cement, non-ferrous metals and glass industry in almost all countries worldwide.
Refratechnik/DE, Haicheng Guotian Mining/CN and Yingkou Jinlong Refractories/CN have signed a Joint Venture (JV) contract for the production of high-grade Caustic Calcined Magnesia (CCM) and Dead Burned Magnesia (DBM) in Pailou, Haicheng/CN.
AMETEK Land will present its SPOT AL EQS, a spot pyrometer that runs complex embedded software algorithms for both temperature and emissivity outputs. Coupled with its latest innovation, a smart actuator for automatic alignment, the SPOT AL EQS can provide accurate temperature measurement for most current extrusion, quench and strip applications.
Bohai Automotive Systems Co., Ltd./CN and TRIMET Aluminium SE/DE have completed their joint venture for TRIMET’s Automotive Division.
RHI Magnesita’s first half results continue to reflect the positive trends seen in the H2/2017, the benefits of a high level of vertical integration and synergies from the combination. Price increases drove revenue development, more than offsetting higher raw material input costs.
Corning Incorporated/US announced that, with the support of the Hefei Government, it will be investing further in an expansion of its new environmental technologies production facility in the Hefei Xinzhan Hi-Tech Industrial Development Zone in the Anhui Province/CN.
Together with Wuhan University of Science and Technology – WUST/CN, Freiberg University of Mining and Technology/DE is planning to set up an international laboratory for new technologies for refractories and metallurgy.
