【摘要】 从提高铁水温度、节约能源角度出发，对３ｔ／ｈ二排大间距冷风冲天炉进行了较全面的测试，分析了炉膛结构、风口比和风口分配比、送风强度、炉气成分和碳耗等因素对熔炼效果的影响，为二排大间距冷风冲天炉的合理使用提供了实践依据和理论说明。更多还原

【Abstract】 In order to raise the temperature of iron smelting and save energy, a two row larger spacing cool wind cupola with a three tons per hour capacity is studied in detail. The influence of parameters such as wind supply furnace gas, distribution ratio of tuyere and tuyere ratio on smelting effect is analyzed. The study also provides an experimental and theoretical foundation for raising the melting temperature and energy efficiency of the cupola.更多还原
