  • Carbothermic Reduction of Ore-Coal Composite Pellets in a Tall Pellets Bed
    minerals Article Carbothermic Reduction of Ore-Coal Composite Pellets in a Tall Pellets Bed Xin Jiang *, Guangen Ding, He Guo, Qiangjian Gao * and Fengman Shen School of Metallurgy, Northeastern University, Shenyang 110819, China; [email protected] (G.D.); [email protected] (H.G.); [email protected] (F.S.) * Correspondence: [email protected] (X.J.); [email protected] (Q.G.); Tel.: +86-24-83681506 (X.J.); +86-24-83691266 (Q.G.) Received: 19 October 2018; Accepted: 21 November 2018; Published: 27 November 2018 Abstract: Recently, increasing attention has been paid to alternative ironmaking processes due to the desire for sustainable development. Aiming to develop a new direct reduction technology, the paired straight hearth (PSH) furnace process, the carbothermic reduction of ore-coal composite pellets in a tall pellets bed was investigated at the lab-scale in the present work. The experimental results show that, under the present experimental conditions, when the height of the pellets bed is 80 mm (16–18 mm each layer, and 5 layers), the optimal amount of carbon to add is C/O = 0.95. Addition of either more or less carbon does not benefit the production of high quality direct reduced iron (DRI). The longer reduction time (60 min) may result in more molten slag in the top layer of DRI, which does not benefit the actual operation. At 50 min, the metallization degree could be up to 85.24%. When the experiment was performed using 5 layers of pellets (about 80 mm in height) and at 50 min duration, the productivity of metallic iron could reach 55.41 kg-MFe/m2·h (or 75.26 kg-DRI/m2·h).

  • Effect of Heat Treatment Method on the Hardness and Corrosion of Ductile Iron in 3.5% Sodium Chloride Solution
    International Journal of Advanced Academic Research (Sciences, Technology and Engineering) | ISSN: 2488-9849 Vol. 6, Issue 9 (September, 2020) | www.ijaar.org Journal DOI: 10.46654/ij.24889849 Article DOI: 10.46654/ij.24889849.e698 EFFECT OF HEAT TREATMENT METHOD ON THE HARDNESS AND CORROSION OF DUCTILE IRON IN 3.5% SODIUM CHLORIDE SOLUTION Oluyori, R.

Corresponding author’s email: [email protected] Abstract In this research, the corrosion response of heat treated ductile cast iron (DCI) used in the production of engine crank shaft was examined. Five samples were used in this work, one of the samples served as control sample, the remaining four samples were subjected to conventional heat treated operations of annealing, normalizing and hardening. The nodular cast irons were heated to initial austenitic temperature of 900°C, held for one (1hour) in the muffle furnace for homogenization, and samples were now cooled in furnace, air, water and oil respectively. Sodium chloride of 3.5% weight percentage solution was used as environment to study corrosion behaviour of the heat treated ductile cast irons. The microstructural images of the control and heat treated samples were resolved and various developed structures are essentially spheroidal graphite, and pearlitic matrix as in the case of the un-heat treated sample, coarse pearlite matrix for the annealed sample, fine pearlite structure for the normalized sample and partially martensitic and fully martensitic matrix for the oil and water quenched samples.

  • Production of Chromium Boride Layers on Carbon Steel with Conversion Treatment: Chromium Deposition + Diffusion Annealing R
    Vol. 132 (2017) ACTA PHYSICA POLONICA A No. 3 Special issue of the 3rd International Conference on Computational and Experimental Science and Engineering (ICCESEN 2016) Production of Chromium Boride Layers on Carbon Steel with Conversion Treatment: Chromium Deposition + Diffusion Annealing R. Boubaayaa;∗, Y. Benariouab, O. Allaouia and M. Djendela aLaboratoire Génie des Procédés, Université de Laghouat, BP 37G, Laghouat, Algeria bDépartement de Génie Mécanique, Faculté de Technologies, Université de M’Sila, BP 166, M’Sila 28000, Algeria The present study has been conducted in order to obtaining chromium boride layers on carbon steel using a conversion processing comprising the following steps: boriding treatment in order to increase the amount of boron atoms in the steel surface, deposition of a thin layer of pure chromium using electrolytic method, and finally an annealing treatment for boron diffusion and formation of boride layer until complete transformation of chromium layer. Depending on the method used (chromium deposition followed by boriding or boriding followed by chromium deposition) and the holding time, the partial or complete conversion is obtained as a result of the diffusion process. The role of the annealing temperature on transformation rates of chromium into chromium boride films was investigated. It is shown that for 1 h at 900 ◦C, the chromium layer is totally transformed. The scanning electron microscopy analysis and X-ray diffraction showed the presence of CrB and CrB2 chromium borides in addition of FeB and Fe2B iron borides.

SUBRAT KUMAR BEHERA Lecturer in Metallurgy DIPLOMA (3rd YEAR-5th SEMESTER) Department of Metallurgical Engineering ORISSA SCHOOL OF MINING ENGINEERING, KEONJHAR A Government of Odisha institution with National Repute Established in the Year 1956 (Approved by AICTE, New Delhi & Affiliated to SCTE&VT, Odisha,BBSR) HEAT TREATMENT PROCESSES In general, heat treatment can be defined as an operation, or the combination of operations that involve heating and cooling of a metal in solid phase to obtain certain required properties. The ferrous materials can be heated to above transformation temperature and can be heat – treated to obtain different structure. The different heat treatment processes are based on heating the material to certain temperature and employing different cooling rates. In this process, heating temperature and rate of cooling adopted plays an important role. The different processes are: Annealing • Stress-relief annealing. • Process annealing. • Spheroidsing. • Full annealing. Normalizing Hardening(Quenching) Tempering Austenite, also known as gamma phase iron (γ-Fe), is a metallic, non-magnetic allotrope of iron or a solid solution of carbon in gamma iron (γ-Fe). It forms above 7230C. It has a FCC crystal structure. The maximum solubility of carbon in austenite is 2.13 % at 1147Oc Fig: - Iron- Carbon Diagram EXPERIMENT-1 Aim: - Annealing of plain carbon steel Apparatus Required: - Hacksaw blade Plain Carbon Steel (Mild Steel) Sample Muffle Furnace File Emery Paper Double disc polisher Etchant (Nital) [98% C2H6OH + 2% HNO3] Metallurgical Microscope Theory: - Annealing generally involves heating to a predetermined temperature, holding at this temperature and finally cooling at a very slow rate The temperature and holding time depend on a variety of factors such as composition, size, shape and final properties desired Annealing treatment can be classified into subdivisions based on temperature of treatment, phase transformation occuring during the treatment and the purpose of the treatment.

  • Iron Recovery from Bauxite Tailings Red Mud by Thermal Reduction with Blast Furnace Sludge
    applied sciences Article Iron Recovery from Bauxite Tailings Red Mud by Thermal Reduction with Blast Furnace Sludge Davide Mombelli * , Silvia Barella , Andrea Gruttadauria and Carlo Mapelli Dipartimento di Meccanica, Politecnico di Milano, via La Masa 1, Milano 20156, Italy; [email protected] (S.B.); [email protected] (A.G.); [email protected] (C.M.) * Correspondence: [email protected]; Tel.: +39-02-2399-8660 Received: 26 September 2019; Accepted: 9 November 2019; Published: 15 November 2019 Abstract: More than 100 million tons of red mud were produced annually in the world over the short time range from 2011 to 2018. Red mud represents one of the metallurgical by-products more difficult to dispose of due to the high alkalinity (pH 10–13) and storage techniques issues. Up to now, economically viable commercial processes for the recovery and the reuse of these waste were not available. Due to the high content of iron oxide (30–60% wt.) red mud ranks as a potential raw material for the production of iron through a direct route. In this work, a novel process at the laboratory scale to produce iron sponge ( 1300 C) or cast iron (> 1300 C) using blast furnace ≤ ◦ ◦ sludge as a reducing agent is presented. Red mud-reducing agent mixes were reduced in a muffle furnace at 1200, 1300, and 1500 ◦C for 15 min. Pure graphite and blast furnace sludges were used as reducing agents with different equivalent carbon concentrations. The results confirmed the blast furnace sludge as a suitable reducing agent to recover the iron fraction contained in the red mud.
