The loading pressing on slide block universal spindle under the friction situation is studied, and the calculation formula of the strength is derived in this original paper. Using the calculation formula, the strength of the slide block universal spindle in the 1100-mm blooming mill in an Iron And Steel Company is calculated. Through analysis, the conclusion is obtained. The distribution law in the stressed surface of the spindle drum’s unit pressure will be changed consequence of friction and wear, and the change of the loading condition promotes the wear of the slide block and the destruction of the fork.

This article examines the efforts of one British steel company to acquire knowledge about American industrial productivity in the first post-World War II decade. It argues that company information-gathering initiatives in this period were overshadowed by the work of the formal productivity missions of the Marshall Plan era. In particular, it compares the activities of the Steel Company of Wales with the Anglo-American Council on Productivity (AACP), whose iron and steel industry productivity team report was published in 1952. Based on evidence from its business records, this study shows that the Steel Company of Wales was undertaking its own international productivity investigations, which started earlier and were more extensive and differently focused from those of the AACP. It makes the case for viewing companies as active participants in the gathering and dissemination of productivity knowledge in Britain’s steel sector after 1945.

Abstract The analysis of the available calculation methods of chain-drives load-carrying ability is given according to the criterion of the tolerance unit pressure in a single profile chain joint [p]0. It is shown, that the values of [p]0 were determined according to the deterministic ideas without consideration of the distribution law of both random varieties of contact step of inner and outer rings and lengths of drive strands of the first and second profile of the chain drive. Probability task of determination of the tolerance unit pressure in two profile chain joints [p0]q is solved, when the structural, technological and physical-mechanical characteristic of the chain, that is, the lengths of drive strand of a chain-drive, accuracy of contact steps and stiffness of a drive roller chain are considered. The measurement procedure and the empirical dependencies for determination of drive roller chains deformation and stiffness are presented. As a result, the dependencies for the determination of [p0]q as the basic criterion according to which selection of a chain dimension-type, as well as characteristics used for the comparative estimation of a drive chain quality of different manufacturers when certain probability estimations are taken into consideration, were obtained.

The prospects of production of special properties steels in the Russian and global metal market are estimated. The necessity of using new types of steels is substantiated. The prospects of introducing steels with special properties developed by PJSC “Magnitogorsk Iron and Steel Company” to the market are determined. Evaluation of measures for the production of large volumes of products showed that there is a problem of a significant increase in the time of manufacturing and delivery of output products to the consumer. As measures to ensure the modernization of the technological complex of the steel enterprise and reduce the time for steel production, the system of jet heat treatment of metal is proposed. According to the results of comparative analysis of the MAGSTRONG H500 and HARDOX 500 alloys used in mining equipment under conditions of increased wear, it was revealed that the proposed method of heat treatment allows one to achieve high wear resistance properties, with high coefficients of tensile strength and toughness.

Through the analysis and study the properties, characteristics and present conditions of the flue slime of blast furnace dust, a suggestion was made of recovering carbon and iron concentrate from the blast furnace dust using a beneficiation technology consisting of gravity separation-flotation. The laboratory test results indicated that it can obtain the iron/carbon concentrate with a grade of iron 53.41%, carbon 65.21% at a recovery rate of iron 51.33%, carbon 69.29%. This mineral processing technology achieved good technical and economical results, reaching the expected effect. The technology can be applied in production and popularized.

Basic Input

At a very early stage in their respective careers, most of the major iron and steel plants of Europe and North America recognized the strategic importance of possessing colliery capacity in order to safeguard their requirements of coking-coal, a basic input to the blast furnace. In the Ruhr—where the tendency towards vertical integration probably reached its apotheosis—the Huttenzechen (tied mines), accounted for nearly twenty per cent of the total coal output at the turn of the century and no less than fifty per cent during the inter-war period. The precise legal standing of the integrated units naturally varied from country to country. In Britain and Germany, for example, the most favoured practice was for the iron and steel plant to establish outright ownership of the mines and to treat them merely as a department of the enterprise complex itself, whereas in the United States, the giant steel works such as Kaiser, Republic, and Bethlehem, preferred to create semi-autonomous subsidiary companies. In India, the two steel firms ofthe pre- Independence era, i.e. the Tata Iron and Steel Company (henceforth abbreviated to T.I.S.CO.) and the Indian Iron and Steel Company (I.I.S.CO.), inclined towards the former organizational model (with the single exception of T.I.S.CO.'s West Bokaro colliery which was purchased in 1947 and was wholly owned by the Company's shareholders).
