| 摘 要： | 利用风口焦炭取样设备在4号高炉（有效容积为2100m^3）进行了风口焦炭取样。首钢焦炭种类多，焦炭质量相对较差，焦炭在炉内劣化严重。分析认为：焦炭质量改进能够减弱风口焦炭劣化、增加风口回旋区长度。对风口焦炭样成分的分析表明，随着焦炭中碱金属含量的降低，风口焦炭劣化度呈减小趋势。

| Abstract: | The equipment of tuyere coke sampling is used in Shougang No. 4 BF . There is much kind of coke in Shougang, but its quality is poorer than Baosteel. If coke quality is improved, tuyere coke granularity tends to be bigger, and the tuyere raceway gets longer. The analysis of tuyere coke composition has proved that with decrease of alkali metal content, degree badness of tuyere coke falls. |

| Keywords: | tuyere coke raceway length granularity alkali metals |
