本文介绍了攀枝花钒钛磁铁矿煤基直接还原新工艺当前纷纷停止、下马局面存在等主要问题及其出现问题的原因。提出了对以转底炉煤基直接还原新工艺为代表的钒钛磁铁矿非高炉新流程的需重新认识、需优先攻克的关键技术,指出了煤基直接还原新工艺处理钒钛磁铁矿发展的努力方向。特别提出了钒钛磁铁矿煤基直接还原新工艺是我国战略技术发展方向,虽然当前面I临许多困难,但不应放弃而且还应大力发展,应抓住攀西试验区建设的战略机遇发展多种形式煤基直接还原新工艺,作为高炉流程的重要补充和创新发展。
This article describes the Panzhihua vanadium-titanium magnetite coal-based direct reduction of the new technology are now stopped, dismount situation and other major problems and their causes of the problem. A new understanding of the new non-blast furnace process of vanadium-titanium magnetite, which is represented by the direct reduction process of coal-base direct reduction of rotary hearth furnace, is put forward. Key technologies to be tackled with priority are pointed out. The vanadium-titanium magnet Mine development efforts. In particular, it is proposed that the vanadium-titanium magnetite coal-based direct reduction process is the development direction of our country’s strategic technology. Although there are many difficulties in the current phase I, we should not give up but also develop vigorously. We should seize the strategic opportunities in the pilot area of Panxi The development of various forms of coal-based direct reduction of new technology, as an important supplement and innovative development of the blast furnace process.
