Abstract

This study was aimed to determine the main cause of lance fracture in a smelting furnace of the Mitsubishi continuous process for Cu production. Investigation of lances used in field operations, thermodynamic analysis and laboratory experiments were conducted. By analyzing the lances, damaged surface of the lances and penetration of matte components into the lance were observed. The depth of damage was strongly dependent on the lance height which was related to temperature. To determine the temperature of the lance fracture, thermodynamics calculations and laboratory experiments were conducted. Both results showed that the formation of Cu liquids above 1100 °C could be the main cause of lance fracture during operation of Cu smelting furnaces of the Mitsubishi process.

三菱工艺的熔炼炉中长枪的铜渗透

摘要

这项研究旨在确定三菱连续生产铜的熔炼炉中喷枪断裂的主要原因。对用于野外作业的喷枪,热力学分析和实验室实验进行了调查。通过分析喷枪,可以观察到喷枪的表面损坏以及雾面组件渗透到喷枪中的情况。损坏的深度在很大程度上取决于与温度相关的喷枪高度。为了确定喷枪断裂的温度,进行了热力学计算和实验室实验。两项结果均表明,在三菱工艺的Cu熔炼炉运行期间,高于1100°C的Cu液体的形成可能是喷枪断裂的主要原因。
