Head Savina L., Registration Date 16-02-2009 Organization The open joint stock company " The Ukrainian research institute of refractories named A.S.Berezhnoy" popup.description2 Object of research - thixotropic refractory runner clay corundum-silicon carbide the structure, used for laying trenches of blast furnaces. The purpose of work - improvement of manufacturing techniques corundum-silicon carbide thixotropic refractory trongh mix for blast furnaces. Methods of researches - physical-mechanical, chemical. The technology corundum-silicon carbide thixotropic refractory runner clay is modified. Comparative researches of influence of different kinds of alumina (СТС-40, ГК-2, СТ 10 SG, СТ 800 SG) on properties corundum-silicon carbide thixotropic refractory runner clay are executed. The opportunity of use in structure corundum-silicon carbide thixotropic refractory runner clay both import, and domestic alumina that has allowed to expand a raw-material base is shown. The production model corundum-silicon carbide thixotropic refractory runner clay of the advanced structure is made. Parameters of properties of weight of a production model after roasting at 1500оС: volumetric changes - 0,1 of the %, open porosity of 20,7 %, the seeming density of 2,91 g/sm3, strength at compression 48 МPа. A normative-technical documentation. Industrial tests corundum-silicon carbide thixotropic refractory runner clay in conditions of Joint-Stock Company " Донецксталь " - a metal works " are lead. The results received during tests have shown, that corundum-silicon carbide the mix of mark СКККТ under the operational characteristics corresponds to similar concrete mixes offered by conducting foreign firms - manufacturers refractories for laying trenches of blast furnaces. Joint-Stock Company " Донецксталь " - a metal works " counts expedient introduction of the specified weight in laying shaking trenches and elements of transport trenches of blast furnaces. Work to continue in a direction of perfection of structure, release of experimental batches and industrial tests developed by open society fire-resistant corundum-silicon carbide mixes for thixotropic refractory weights.
