一、前言锰铁高炉生产时会经常遇到因入炉混合矿成分波动而引起熔剂量变化的情况,如对此调节不及时,必然导致破坏冶炼热平衡,造成热制度波动,进而影响金属还原率。为此,必须稳定热制度。主要手段是调整风温和焦炭批重。调整风温受以下两点限制:一是高炉生产的原则是要尽量使用高风温,因而向上调风温受到限制;二是长期使用低风 First, the preface Ferromanganese blast furnace production will often encounter due to fluctuations in composition of the furnace mixed ore flux caused by changes in the situation, such as this adjustment is not timely, will inevitably lead to destruction of smelting heat balance, resulting in fluctuations in thermal regime, thereby affecting the metal reduction rate . To this end, we must stabilize the thermal system. The main means is to adjust the wind temperature and coke weight. Adjust the temperature by the following two restrictions: First, the principle of blast furnace production is to try to use the high temperature, thus increasing the temperature to be limited; the second is the long-term use of low wind
