| 摘 要： | 针对PMC矿的利用问题，对PMC精矿与司家营矿粉以7[∶]3配矿比例造球的氧化焙烧行为进行了研究。研究结果表明，当预热时间为10 min、焙烧温度为1 275 ℃、焙烧时间为20 min时，球团抗压强度随预热温度的升高呈现先升高后降低的趋势，当预热温度为925 ℃时，球团抗压强度达到最大为2 765.75 N/个；当预热温度为925 ℃、焙烧温度为1 275 ℃、焙烧时间为20 min时，球团抗压强度随预热时间的延长由2 64升高到2 833.61 N/个；当预热时间为15 min、预热温度为925 ℃、焙烧时间为10 min时，球团抗压强度随焙烧温度的升高由674.96升高到2 503.83 N/个；当预热时间为15 min、预热温度为925 ℃、焙烧温度为1 300 ℃时，球团抗压强度随焙烧时间的延长由2 503.83升高到2 872.52 N/个。

| Abstract: | The effects of pre-heating temperature,pre-heating time,roasting temperature and roasting time on consoli-dation properties of the pellet were studied to utilize PMC. The pellet was composed of PMC and the PMC mineral to Si-jiaying mineral powder was 7∶3. Results show that,when the preheating time is 10 min,the roasting time is 20 min, and the roasting temperature is 1 275℃,the compression strength of the pellet increases firstly and then decreases with the increase of pre-heating temperature. When the pre-heating temperature is 925℃,the compression strength of the pellet reaches the maximum,which is 2 765.75 N/per. When the pre-heating temperature is 925 ℃,the roasting time is 20 min and the roasting temperature is 1 275℃,the compression strength of the pellet increases from 2 646 N/per to 2 833.61N/per with the increase of pre-heating time. When the preheating time is 15 min,the roasting time is 10 min and the pre-heating temperature is 925℃,the compression strength of the pellet increases from 674.96 N/per to 2 503.83 N/per with the increase of roasting temperature. When the preheating time is 15 min,the pre-heating tempera-ture is 925℃and the roasting temperature is 1 300℃,the compression strength of the pellet increases from 2 503.83 N/per to 2 872.52 N/per with the increase of roasting time. |
