| 摘 要： | 通过对南钢冷态焦炭、凉焦台焦炭、热态焦炭喷洒焦炭添加剂溶液,测试其热态性能变化规律;在20 kg小焦炉上进行4种配煤方案的炼焦试验,研究焦炭添加剂对改善焦炭质量所起的作用.在此基础上,提出喷洒焦炭添加剂溶液的最佳生产工艺和技术参数,在焦化厂进行焦炭喷洒焦炭添加剂溶液试验,在炼铁厂3号高炉同步进行应用试验.试验表明:焦炭添加剂能改善焦炭的热态性能指标,高炉使用喷洒焦炭添加剂溶液后的焦炭,炉况顺行,增铁、节焦效果明显,经济效益显著.

| Abstract: | The thermal properties of cokes, such as hot-coke, cold-coke and coke on wharf by spray with coke additive was measured at Nanjing Steel. The coking tests with 4 coal blending schemes were carried out on 20 kg test oven to study the effect of coke additive on coke quality. The best technology index of coke additive spray was ohtained, then an application experiment on the coke sprayed with coke additive was carried out at coking plant and No. 3 blast furnace in the ironmaking plant. The practice shows that coke additive can improve obviously thermal properties of coke, making No. 3 blast furnace work smoothly, increase obviously output of hot metal and decrease coke rate up to great economic benefits. |
