本文从提高铁水温度、节约能源角度出发,通过对武汉鼓风机厂使用的3.5吨/小时三排小风口冷风冲天炉进行了较全面的测试和试验研究工作,找出了较佳的结构参数和工艺参数范围,从而获得了较好的熔炼效果。本文着重分析风口比、主风口的设置及尺寸大小以及送风强度对冲天炉熔炼效果的影响,为三排小风口冷风冲天炉的合理使用、提高熔炼效果、达到提高铁水温度和节约能源的目的提供了实践依据和理论说明。 This article from the perspective of increasing the temperature of hot metal, energy conservation, through the use of 3.5 mph in Wuhan blower factory three rows of small air outlet cold cupola more comprehensive test and experimental research to identify the better structural parameters and processes Parameter range, so as to obtain a better smelting effect. This article focuses on the analysis of the tuyere ratio, the main air vents and the size of the size and strength of the blast furnace melting effect, for the three rows of small air-cooled cupola reasonable use, improve the melting effect, to achieve the purpose of raising the temperature of molten iron and energy conservation Provided a practical basis and theoretical description.
