Title: The Innovations of Hans-Jurgen Gulas
Introduction
Hans-Jurgen Gulas is a notable inventor based in Leoben, Austria. He has made significant contributions to the field of refractory materials, holding 2 patents that showcase his innovative approach to material science. His work has implications for various industrial applications, particularly in the metallurgy sector.
Latest Patents
Gulas's latest patents include a fired refractory brick and a process for preparing the same. This invention involves a fired refractory brick composed of magnesia, 2 to 10% alumina, calcium oxide, and up to 1.5% silica. The weight ratio of calcium oxide to silica is more than 1.4, and it contains at least 2.2(CaO -1.4 SiO.sub.2)% zirconia. The calcium and zirconium in the brick form a calcium zirconate phase, with its content ranging from 0.5 to 8%, all percentages being by weight. The brick is prepared by pressing a mixture of these components into the shape of a brick and firing it at temperatures between 1600°C and 1800°C until the desired calcium zirconate phase is achieved. Another significant patent is for a refractory lining for a pig iron container, which comprises magnesite-chromite bricks containing 15-30% by weight of chromic oxide. The chromite is highly dissolved in the brick mass, ensuring that it has no more than a 12% by volume residue of chromite.
