The change of hot strength of iron ore pellets during oxidizing roasting and reduction was researched 摘要研究了球團(tuán)礦在氧化焙燒和還原過(guò)程中抗壓強(qiáng)度的變化規(guī)律。
A critical temperature was found , at which the strength of pellets is severely dropped during the oxidizing roasting 使用可調(diào)氣氛高溫抗壓試驗(yàn)機(jī)研究了相應(yīng)球團(tuán)礦在氧化焙燒過(guò)程中的強(qiáng)度變化規(guī)律。
The strength variation of pellets during oxidizing roast was studied with a high temperature compressive tester with adjustable atmosphere 通過(guò)還原反應(yīng)后的高溫抗壓強(qiáng)度研究估算了球團(tuán)礦焙燒中必要的強(qiáng)度。
