The jubilee year of ?Ogneupory?

Abstract

666.762 During the last 60 years, "Ogneupory" brought specialists of the field of refractories together and, thereby, formed the main driving force for the development of the refractories industry. The journal elucidated new scientific thoughts and progressive technological methods and formed a forum where the behavior of refractories was predicted and analyzed, critical reviews were made, and specialists were taught and trained.The first contributors to the journal belonged to the Ukrainian Institute During 1933During -1940, the journal published results of extensive studies carried out on refractory raw materials and refractories.Several article dealt with the development of technologies of chamotte refractories for the Chasovoyarsk complex and the Kondrat'evsk, Bogdanovichsk, Semiluksk, Sukholozhsk, and Podol'sk plants, magnesia refractories for the "Magnezit" complex and the Panteleimonovsk plant, and dinas refractories for the Krasnoarmeisk, Pervoural'sk, and Krasnogorovsk plants.During these years, 12 laboratories and the pilot plant of the Institute rendered constant help in maintaining and developing the refractories industry. In view of the increasing demands of ferrous metaUurgy, in 1933 the Institute was handed over to the Central Management of the metallurgical industry. The Institute concentrated mainly on developing production technologies of chamotte, dinas, and magnesia refractories and exploring the possibilities of widening the raw materials base of the refractories industry. During 1933-1937 the Soviet refractory enterprises met the demands of the metallurgists for constructing different types of furnaces, including blast furnaces, open-hearth furnaces, coke ovens, reheating furnaces, and air heaters, and for making the linings of the steel-teeming ladles. By 1940, the annual production of refractories increased to 23 million ton, i.e., it increased by 4 times as compared to the production of 1928 [1]. During this period, several studies were carried out on the technology of clinas, siliceous raw materials, high-temperature transformation of the minerals of silica, and the effect of mineralogical and bonding additives, oxides of calcium and iron, and SSB on the strengthening processes of dinas raw materials during the course of drying and the products during the firing operation [2][3][4][5][6][7][8][9][10][11][12][13][14][15].Aspects concerning the development of dinas refractories for lining coke ovens [16][17][18][19][20] (including the method of accelerated firing of dinas [21, 22] received significant attention. A number of refractories were studied with reference to the lining of cupola furnaces, and it was established that semiacidic refractories are the best for lining cupolas [23]. Studies were carried out on kaolin raw materials for obtaining semiacidic and chamotte refractories required for the Krasnogorovsk, Maidan-Vil'sk, and Prosyanovsk plants [24] and on clays obtained from the Zinov'evsk deposit [25] and Ovruchsk shales [26]. A technology of obtaining refractories requi...

Natural aluminosilicate raw material for production of mullite-silica fiber materials

“…Above 1010~ the existence of SiO is probable while at lower temperatures SiO decomposes with formation of silicon and silica [5].In heating of natural aluminosilicates dehydration of the minerals occurs with formation of new phases and finally melting at high temperatures. At present for production of mullite-silica fiber materials the majority of leading foreign firms in this area and the USSR use artificial mixtures of alumina and silica [I].…”
