一、风机的使用简况鼓风机是冲天炉重要的附属设备,其作用是保证向炉内连续地强制送风,克服送风系统和炉内各部分的阻力,供应炉内底焦燃烧所必需的空气使熔炼能正常进行。因此,冲天炉熔炼对供风的基本要求应是在保证一定供风量的前提下具有一定的压力。长期以来,由于国内冲天炉熔炼使用的焦炭质量差(块度小、灰分高、强度低),为改善炉内底焦的燃烧,希望供风能尽量深入炉 First, the use of fan Briefing Blower is an important ancillary equipment, its role is to ensure continuous forced air supply to the furnace to overcome the air supply system and the resistance of various parts of the furnace, the bottom of the furnace supply of coke required for combustion of air So that the normal melting process. Therefore, the basic requirements of cupola melting for the wind should be under the premise of a certain supply of air to ensure a certain amount of pressure. For a long time, due to poor quality of coke used in cupola smelting (small block size, high ash content and low strength), in order to improve the combustion of bottom coke in the furnace,
