Zuzel ten odznacza sie dosc wysoka temperatura topnienia, jednak przeróbka jego na material ogniotrwaly nie uda¬ wala sie z powodu jego wielkiej twardosci. Twar¬ dosc zuzla utrudnia lub nawet uniemozliwia jego drobne mielenie konieczne do sporzadzania z nie¬ go wyrobów ogniotrwalych.Celem wynalazku jest usuniecie tych niedogod¬ nosci. Cel ten osiaga sie przez opracowanie spo¬ sobu wedlug wynalazku, który polega na tym, ze zuzel giinowo^tyitamowy w ilosci 50—90°/o wago¬ wych miesza sie z magnezytem spieczonym w ilo¬ sci 10^50°/o wagowych. Z mieszaniny tej sporza¬ dza sie pólprodukt przez zbrykietowanie i wypra¬ zenie w temperaturze 1200—4600°iC.

So far, attempts have been made to use many times as a refractory waste material. Iron titanium slag containing (only the main constituents of aluminum and titanium oxides. This slag has a fairly high melting point, but its processing into refractory material was unsuccessful due to its high hardness). The hardness of the slag makes it difficult or even difficult. prevents its fine grinding necessary for the preparation of refractory products from it. st removal of these inconveniences. This object is achieved by developing a process according to the invention, which consists in that 50-90% by weight of gin and tyitam glaze is mixed with 10-50% by weight of sintered magnesite. The mixture is then made into a semi-finished product by briquetting and baking at a temperature of 1200 ° -4600 ° C. Then refractory products are formed from the calcined and crushed semi-finished product, and then they are fired at a temperature of 1300-1700 ° C. The initial mass is partially or completely replaced with sintered magnesite with an equal amount of raw magnesia, and caustic magnesia. tangential, magnesium chloride or other raw materials, the main component of which is magnesium oxide. To prepare the mixture, aluminum-titanium slag in the amount of 50-90% by weight is used, crushed to a grain size of less than 2 - 4 mm and matgnesite sintered in 10-60% by weight, crushed to a grain size below 0.2 mm. Next, this mixture is formed into briquettes of any shape and size, and then calcined in rotary, shaft, tunnel or periodic furnaces at In nature 1200 ^ 1'600 PL
