摘要

采用Setsys Evolution同步热分析系统对(1)氧化镁+碳粉+单质硫

(2)氧化镁+碳粉+硫化亚铁

(3)氧化镁+碳粉+硫化亚铁+铝粉+赤铁矿(Fe

) 3种试验方案以10～25℃/min的升温速度在1 350℃氮气中试验研究了MgO-C-S(FeS)反应的热力学过程

得出差热-热重曲线。结果表明

MgO-C-FeS体系的反应温度要低于MgO-C-S体系的反应温度

在MgO-C-FeS体系中加入发热剂

会使体系的反应提前。

Abstract

With using Setsys Evolution synchronous thermal analysis system the thermodynamic process of reaction of MgO-C-S (FeS) on 3 kinds of scheme- (1 ) magnesium oxide + carbon powder + sulphur

( 2 ) magnesium oxide + carbon powder + ferrous sulfide and (3 ) magnesium oxide + carbon powder + ferrous sulfide + aluminum powder + hematite (Fe

) with heating rate 10 ~25 °C/min nitrogen atmosphere at 1 350 ℃ has been tested and researched to get differential thermal-thermo gravimetric curves. Results show that the reaction temperature of MgO-C-FeS system is lower than that of MgO-C-S system

and with adding thermite in MgO-C-FeS system the reaction of system shall be moved up.
