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