Phase Equilibrium Studies in the CaO–SiO2–Al2O3–MgO System with MgO/CaO Ratio of 0.2Metallurgical 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 ProblemMetallurgical 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
Calculation of Static Suspension Depth and Meniscus Shape of a Solid Spherical Inclusion at the Steel–Slag InterfaceMetallurgical 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 slagsMetallurgical 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 AcidMetallurgical 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
