Phase Equilibrium Studies in the CaO–SiO2–Al2O3–MgO System with MgO/CaO Ratio of 0.2
Metallurgical and Materials Transactions B - Tập 54 - Trang 793-806 - 2023
Jinfa Liao, Gele Qing, Baojun Zhao
With the raw materials for ironmaking are becoming increasingly complex, more accurate control of blast furnace operation is essential to reduce the energy cost and CO2 emission. CaO–SiO2–Al2O3–MgO is a basic system of ironmaking slag in which CaO and MgO are mainly come from the flux, SiO2 and Al2O3 are mainly from the raw materials. Effect of raw material composition on phase equilibrium of the ...... hiện toàn bộ
Calculation of Heat Flux Across the Hot Surface of Continuous Casting Mold Through Two-Dimensional Inverse Heat Conduction Problem
Metallurgical and Materials Transactions B - Tập 46 - Trang 2137-2152 - 2015
Haihui Zhang, Wanlin Wang, Lejun Zhou
A novel method for the estimation of the mold hot surface heat flux based on the measured responding temperatures from two columns of thermocouples that embedded inside the mold during continuous casting has been developed. The method includes a Two-Dimensional Inverse transient Heat Conduction Problem (2D-IHCP) model that was solved by the conjugate gradient method with Adjoint Equation. The mode...... hiện toàn bộ
Discussion of “Derivation and consistency of the partial functions of the ternary system involving interaction coefficients”
Metallurgical and Materials Transactions B - Tập 27 - Trang 325-326 - 1996

Calculation of Static Suspension Depth and Meniscus Shape of a Solid Spherical Inclusion at the Steel–Slag Interface
Metallurgical and Materials Transactions B - Tập 51 - Trang 422-425 - 2020
Wei Liu, Shufeng Yang, Jingshe Li
A method to calculate the meniscus shape around an inclusion on the steel–slag interface is presented. The meniscus shape is related to the properties of steel and slag and the size of the inclusion. The large-size inclusions have a large suspension depth and interaction range. At the small-size range of inclusions, the suspension depth increases slowly with the size, while the interaction range i...... hiện toàn bộ
Sulfide capacities of fayalite-base slags
Metallurgical and Materials Transactions B - Tập 26 - Trang 325-334 - 1995
S. R. Simeonov, R. Sridhar, J. M. Toguri
The sulfide capacities of fayalite-base slags were measured by a gas-slag equilibration technique under controlled oxygen and sulfur potentials similar to those encountered in the pyrometallurgical processing of nonferrous metals. The oxygen pressure range was from 10−9.5 to 10−11 MPa and the sulfur pressure range from 10−3 to 10−4.5 MPa, over a temperature range of 1473 to 1623 K. The slags studi...... hiện toàn bộ
Reductive Leaching of Low-Grade Pyrolusite with Formic Acid
Metallurgical and Materials Transactions B - Tập 46 - Trang 1709-1715 - 2015
Youzhi Lu, Huaju Ma, Runjun Huang, Aiqun Yuan, Zengwei Huang, Zeguang Zhou
The extraction of manganese from low-grade pyrolusite is investigated using formic acid as reductant in sulfuric acid medium. The effects of volumes of formic acid, concentration of sulfuric acid, liquid to solid ratio (L/S), leaching time, and temperature on leaching efficiency of manganese, iron, and aluminum are valuated with single-factor experiments. The results show that the leaching efficie...... hiện toàn bộ
A Coupled Thermal, Fluid Flow, and Solidification Model for the Processing of Single-Crystal Alloy CMSX-4 Through Scanning Laser Epitaxy for Turbine Engine Hot-Section Component Repair (Part I)
Metallurgical and Materials Transactions B - Tập 45 - Trang 2247-2261 - 2014
Ranadip Acharya, Rohan Bansal, Justin J. Gambone, Suman Das
Scanning laser epitaxy (SLE) is a new laser-based additive manufacturing technology under development at the Georgia Institute of Technology. SLE is aimed at the creation of equiaxed, directionally solidified, and single-crystal deposits of nickel-based superalloys through the melting of alloy powders onto superalloy substrates using a fast scanning Nd:YAG laser beam. The fast galvanometer control...... hiện toàn bộ
Assessment of Nusselt Number Correlations for Liquid Metals Applied in Alloying Processes in Turbulent Flows
Metallurgical and Materials Transactions B - - 2021
Kinnor Chattopadhyay, R. D. Morales, Alfonso Nàjera-Bastida, Jafeth Rodríguez-Ávila, Carlos Rodrigo Muñiz-Valdés
Nghiên cứu so sánh thực nghiệm và số để điều tra những lợi ích tương đối của bộ tản nhiệt và các chèn hình "C" trong việc làm mát cuộn dây cán nguội Dịch bởi AI
Metallurgical and Materials Transactions B - Tập 37 - Trang 1015-1024 - 2006
Tathagata Bhattacharya, Debadi Chakraborty, Vikas Singh
Thiết bị làm mát và lưu trữ cuộn dây (CCSU) được sử dụng để làm lạnh những cuộn dây cán nguội đến nhiệt độ cán nhẹ sau khi chu trình tôi đã kết thúc tại lò tôi lô (BAF) trong một nhà máy cán nguội (CRM). Trong CCSU, các cuộn dây được giữ trên các bệ làm mát trong một thời gian cố định bất kể loại và trọng tải. Do đó, cần phải có một mô hình toán học để dự đoán chính xác thời gian làm mát của các c...... hiện toàn bộ
