Analysis of the factors affecting the fuel rate in the COREX process and improvement measures

摘要

Increasing production capacity and operating rate,reducing fuel rates and costs of hot metal (HM) are the urgent tasks for the COREX process.In this study,the various factors on the fuel consumption of COREX are researched from the theoretical analysis based on the calculations of material balances and heat balances.Combined with the production performances and practices of COREX-2000 (Saldanha,India) and COREX-3000 (Baosteel),the technical measures of reducing the fuel rate are analyzed and the way forward of technical innovation is addressed and discussed with the standpoint of the COREX process improvement.
