Head Dunikov A., Registration Date 25-01-2008 Organization The open joint stock company " The Ukrainian research institute of refractories named A.S.Berezhnoy" popup.description2 Object of the study - testing techniques, test and exploratory equipment for determination characteristic refractory material and product, production heat equipment .The purpose of the work - updating and mastering the testing techniques: МВИ 322-42-2002 " Technique of the performing the measurements of the ultimate flexural strength refractory of thermo-insulating slabs ", МИ 322-65-2004 "Refractory products with the general porosity less 45 %. The technique of the determination of the ultimate flexural strength under room temperature"; mastering testing methods of thermo-insulating fibrous refractory in accordance with ГОСТ 23619-79 for the determination appearing density, content of the nonfibrous inclusions, sizes products; the determination of the thermo-insulating layer optimum thickness of the feeder channel of the glass furnace by way of the thermotechnical calculation; the revising to technical documentation on test unit for determination refractoriness under load in accordance with ГОСТ 4070-2000. The methods of the studies are theoretical, experimental studies and development. They are executed updating and mastering of the testing techniques: МВИ 322-42-2002 " Technique of the performing the measurements of the ultimate flexural strength refractory of thermo-insulating slabs ", МИ 322-65-2004 " Refractory products with the general porosity less 45 %. The technique of the determination of the ultimate flexural strength under room temperature ", as a result in lieu thereof mentioned techniques was designed, approved and qualified technique МИ 322-65-2007. Testing methods of thermo-insulating fibrous refractory in accordance with ГОСТ 23619-79 for the determination appearing density, content of the nonfibrous inclusions, sizes products are masterred. As a result of mathematical modeling with using of the thermotechnical calculation is determined of the thermo-insulating layers optimum thickness of the feeder channel of the glass furnace in the open joint stock company "Poltava's plant of medicalglass " and are offered two variants of the feeder lining (with refractory), providing use designed in the open joint stock company "UKRNIIO named A. S. Berezhnoy" concrete from thermo-insulating mixture of the mark САНБТ-0,8 in the feeder lining. The technical documentation on test unit for determination refractoriness under load in accordance with ГОСТ 4070-2000 is revised. The results of the research effort are introduced in practical person of the functioning (working) the open joint stock company "UKRNIIO named A. S. Berezhnoy". Work will is continued toward mastering, improvement and harmonization with international standard of the testing methods of the refractory and technical ceramics.5635 Product Description popup.authors popup.nrat_date 2020-04-02 Close
