The wide range of process solutions developed by TOREX team as to retrofitting of the indurating machine MOK-592 led to a core target achievement - production of the high quality material and fired pellets at all process stages. These materials to be used for onward blast furnace smelting and DRI processes (whereby a strength is 280 kg/pellet and FeO content is lower than 0,5 %) with lower consumption of energy resources (e.g. consumption of natural gas is below 10 m3/t, power consumption within entire technological complex is lower than 36 KW·h/t) with a min negative environmental impact. In this case, a total ramp up of production rate in reference to design values has been increased by 10%. The named project solutions result in significant expansion of pellet product list at the "Mikhailovsky GOK after A.V. Varicheva" JSC along with improvement of consumer properties of pellets.
To minimize the emissions of sulfur dioxide, TOREX experts jointly with academicians of Urals Federal University elaborated the wet desulfurization technology to clean the flue gases discharged from indurating machine with application of ground limestone as a chemical agent. The project scope of works comprise the required technological calculations, development of technical documentation and simulation of pilot plant along with manufacturing and procurement of its key equipment components, research of desulfurization by-products (sludge, flue gas, water). The pilot plant is designed to simulate the technological procedures of flue gas treatment under various parameters (temperature, pressure, content of SO2) and during production of versatile types of material. The target is to verify the equipment under actual operating conditions and to prove an efficiency of selected desulfurization technology.
TOREX company has presented the state-of-the-art technology under its trade name NextGen Pelletizing© to the global iron ore industry, in reliance on viable operation of the new generation indurating machine in Russia. To improve a power efficiency of the NextGen Pelletizing© technology, Tek7 engineers have employed CFD, FEA and other simulation methods. This novel approach to design philosophy along with advantageous thermal circuit developed by TOREX ensure a max efficacy and customization of individual elements of the indurating machine tailored to specific targets and conditions of a Client.
Engineering company TOREX - Technology. Optimization. Retrofitting. Expertise
is an engineering company which solves different challenges in the pelletizing sphere with the use of various raw materials to meet the final product requirements. Our own way to upgrade an efficiency of the pelletizing process lies in an application of the new process solutions based on the scientific approach and in-detail elaboration. Nevertheless, we never underestimate a sophisticated human resources of TOREX who are the core source of high-qualified and profficient works. Nowadays, TOREX staff includes 41 employees, 8 Ph.D. in Engineering Science, 1 Doctor of Engineering Science and numerous experienced scientific employees.
The company unites professional highly qualified specialists with deep competencies in pelletizing and sintering processes and their thermal engineering. TOREX has concentrated major scientific achievements and practical experience. This experience is summarized in the special publications and detalized in the unique research and computational techniques that our specialists employ in their practice.
All specialists have ample opportunity to practice their research skills at mining and metallurgical enterprises in Russia, Ukraine and Kazakhstan. Among these are Lebedinsky Ore Dressing Combine (LGOK), Mikhailovsky Ore Dressing Combine (MGOK), Oskol Electrometallurgical Plant (OEMK), Uralskaya Stal (Ural Steel), Karelsky Okatysh (Karel Pellet Plant), Evraz group enterprises, Novolipetsk Steel Plant (NLMK); Central Ore Combine (CGOK), Inguletsky Ore Dressing Combine (InGOK) in Ukraine; Sokolov-Sorbay Ore Processing Enterprise (SSGPO) in Kazakhstan.
First of all, TOREX is a unique team of experts in the main technology areas of the company. The emergence of such specialists has been made possible only in one way:
− Quality education and the development of basic knowledge;
− Study of reference materials and experience gained by our predecessors,
− Finally, the development of practical skills through active participation in existing projects of the company.
To date, TOREX team consists of 45 employees, including 10 doctorate candidates and doctors of technical sciences among which are both experienced scientists and young professionals. Young graduates are actively exploring accumulated skills and techniques.
