中文摘要：为提高冲天炉的综合性能，通过采取中央集中送风，合理控制风口风速，合理的炉膛结构，防止风嘴熔化等措施，强化焦炭燃烧，增加了焦炭的燃烧比，提高了冲天炉熔炼铁液的出炉温度；能适用混合焦炭，简化了焦炭处理；使炉衬侵蚀减小，修炉简便。通过多年实践改进，完善了中央送风冲天炉的相关工艺参数。该炉型操作简单，有利于降低硅、锰烧损和节能，打炉方便，生产稳定，可在同行业推广。
英文摘要：To improve the overall performance of cupola, taking the measures of centralized air supply, reasonable air control speed, reasonable furnace structure and preventing the tuyere from melting, the process of coke combustion is enhanced, the combustion ratio of coke increases and the tapping temperature of cupola melting iron improves. Mixed coke can be applied under the above measures, so the coke processing is simplified, which reduces lining erosion, makes repairing furnace simple. Through practicing and improving in years, the relevant process parameters of central blast-heating cupola are perfected. The cupola is simple in work and stable in production, which can reduce silicon-manganese melting loss and save energy. The cupola is worth of spreading in the same industry.
