炉底中央送风是改善燃烧条件的一种较好的方法。我厂于一九六○年在学习了北京、沈阳等地的炉底中央送风冲天炉经验的基础上,经过百余次试验、改进,把中央送风冲天炉发展成为目前的短风咀、曲线炉膛、炉身预热的结构,使具有生产稳定、铁水温度高、熔化速度快、焦炭消耗低、炉壁浸蚀少、结构简单、操作方便等特点。 Central blowing of the hearth is a better way to improve the combustion conditions. I plant in 1960 in Beijing, Shenyang and other places under the heart of the bottom of the cupola experience based on the furnace, after more than 100 tests, improvements, the central air cupola developed into the current short-Tsui , Curve furnace, preheat body structure, so that with a stable production, hot metal temperature, fast melting speed, low coke consumption, furnace wall erosion less, simple structure, easy operation and so on.
