采用烧结杯实验和现场测试相结合的方法,研究了烧结过程中气流分布对烧结矿质量的影响。通过现场测试得知,双烟道两侧各风箱支管的气流分布存在波动,烧结机上表层烧结矿表观不均匀,矿相上也存在一定差异。烧结杯试验结果表明,在现场原燃料条件下,烧结工艺参数最佳控制范围是点火负压为10~11 kPa、烧结负压11~12 kPa、点火温度1 030℃左右。按上述参数调整生产工艺,可达到提高烧结矿质量的目的。
The sintering cup experiment and field test are combined to study the influence of the air flow distribution on the sinter quality during the sintering process. The field test shows that there is fluctuation in the airflow distribution of the bellows on both sides of the double flue. The surface sinter on the sintering machine shows uneven appearance and there are some differences in the ore facies. Sintering cup test results show that under the condition of raw fuel in the field, the optimal control parameters of sintering process are the ignition negative pressure is 10 ~ 11 kPa, the sintering negative pressure is 11 ~ 12 kPa and the ignition temperature is about 1 030 ℃. According to the above parameters to adjust the production process, can achieve the purpose of improving the quality of sinter.
