焦炭的块度过大在炉内所需耗氧量相同但停留时间过长,焦与焦之间间隙较大,同一批料熔化时间有较大差异,对铁液温度影响较大;焦炭的块度过小,增加炉内阻力不利于正常熔化铁液。灰分含量过大炉内渣子过稠,氧化不充分极易风眼结渣造成温度过低,甚至有凝炉的事件发生。固定碳含量即发热量高低直接影响温度高低,强度和反应性的变化直接影响炉内燃烧效果。金属炉料的合理搭配是降低成本,达到要求成分的关键,块度过大会产生落生现象造成铁液温度偏差较大;块度过小过薄在熔化过程中顺着焦炭间的间隙极快通过过热区,如果数量较多对铁液影响 Excessive block coke in the furnace required the same amount of oxygen but the same residence time is too long, the larger the gap between coke and coke, the same batch melting time have a greater difference, a greater impact on the temperature of molten iron; coke Block size is too small, increasing the furnace resistance is not conducive to the normal melting of molten iron. Ash content is too large too thick slag in the furnace, oxidation is not fully easy to wind eye slagging caused by temperature is too low, and even coagulation furnace incident. Fixed carbon content that is, the level of heat directly affects the temperature level, the intensity and reactivity changes directly affect the combustion effect in the furnace. Reasonable collocation of metal charge is to reduce costs, the key to the requirements of the ingredients, the assembly of the mass produced over the General Assembly caused a large deviation from the hot metal temperature; block too small too thin in the melting process along the gap between the coke quickly passed Overheating zone, if the number of more impact on the molten iron
