Development of a Mechatronic System for the Main Drive of a Cold Pipe Rolling Mill
Steel in Translation - Tập 53 - Trang 898-902 - 2024
K. V. Litsin, A. A. Klimenko, R. N. Kalinin, I. A. Orekhovskii, D. R. Azibaeva
The operation of the cold pipe rolling mill of JSC Sinarskii Pipe Plant is considered. A solution was proposed to modernize the main drive of the mill by forming four subsystems: the main drive, which ensures the movement of the main mechanism (stand) during pipe rolling; drive of working feed of the workpiece by 15–30 mm when the stand passes the extreme positions; front chuck rotation drive; rod...... hiện toàn bộ
Pipe rolling on a short mandrel with kinematic tension
Steel in Translation - Tập 46 - Trang 39-41 - 2016
A. A. Bogatov, D. A. Pavlov, E. A. Pavlova
Improvement in pipe production on a longitudinal rolling mill is proposed. The tandem longitudinal pipe rolling mill in the pipe-mill aggregate (PMA)-140 at PJSC (public joint-stock company) Sinarsky Pipe Works is considered. Currently, pipe is produced both from rolled billet (diameter 120 mm) and from continuous-cast billet. To reduce costs, it would make sense to discontinue the use of rolled b...... hiện toàn bộ
Estimation of Sulfide Capacity of Slags Using Ionic Theory

Formation of a Gradient-Layered Structure during Thermal Deformation Treatment of Reinforced Steel
Steel in Translation - Tập 50 - Trang 509-513 - 2020
A. T. Kanaev, A. V. Bogomolov
In this study, we consider the mechanism and kinetics of structure formation in the hardened zone during thermal deformation treatment of reinforced steel. Depending on the cooling rate and temperature conditions of austenite decomposition, pearlite and martensitic transformations are shown to occur with the formation of a gradient-layered structure, leading to structure modification of the surfac...... hiện toàn bộ
Coal-dust fuel and blast-furnace production in Ukraine
Steel in Translation - Tập 40 - Trang 901-908 - 2011
A. N. Ryzhenkov, A. A. Minaev, S. L. Yaroshevskii, B. P. Krikunov, V. M. Zamuruev, A. I. Dreiko
The possibility of introducing coal-dust fuel at Ukrainian metallurgical plants is considered. The use of coal dust in blast furnaces at rates of 120 kg/t of hot metal immediately reduces coke consumption by 2.7 million t and natural-gas consumption by 1.2 billion m3. In addition, by compensation of the negative impact of coal dust on the technology, the time for conversion to blast-furnace smelti...... hiện toàn bộ
Lignite-coke briquets in ferroalloy production
Steel in Translation - Tập 45 - Trang 207-211 - 2015
V. P. Vorob’ev, P. P. Orlov, S. R. Islamov, S. G. Stepanov
Kansko-Achinsk 2B and 3B coal is of interest not only as a fuel but also as a raw material for the production of metallurgical reducing agents. Theoretical and practical aspects of the manufacture of briquets based on medium-temperature coke (thermocoke) produced from Berezovsk 2B lignite and their use in ferroalloy smelting are considered. The new material is compared with metallurgical coke. Key...... hiện toàn bộ
Radical reconstruction of bar production at OAO MMK
Steel in Translation - Tập 37 - Trang 152-157 - 2007
V. F. Rashnikov, G. S. Senichev, A. V. Gasilin, O. P. Shiryaev, V. G. Loginov
Inspection of the Metal Microstructure in Laser-Surfaced Rollers
Steel in Translation - Tập 48 - Trang 403-410 - 2018
A. V. Belonosov, O. A. Chikova, N. A. Zaitseva
The microstructure and crystalline structure of laser-surfaced 9Kh2MF and 8Kh3SMFA steel samples are studied. Samples are taken from the working rollers of the reversible rolling mill at PAO Uralmashzavod. Sealing of surface cracks in the rollers by means of a laser is regarded as an effective repair method in small-scale production. The goal of the research is to monitor the quality of laser-surf...... hiện toàn bộ
Structural changes of multiphase low-carbon steel in deformation and heat treatment
Steel in Translation - Tập 44 - Trang 928-930 - 2015
V. G. Mishchenko, S. P. Sheyko
The influence of the rolling parameters on the structural and phase transformations and mechanical properties of steel is analyzed. At a particular combination of temperature, strain, and strain rate, fine-grain austenite structure may be obtained, with highly developed polygonal substructure. For low-carbon steel, the best combination of cooling and winding parameters after rolling is as follows:...... hiện toàn bộ
