制备内配燃料熔剂性含镁赤铁矿球团时，将焦粉配比控制1.5%以内，球团碱度控制在0.9，可显著提高焙烧球团强度。
When preparing the fluxed magnesium hematite pellets with the fuels, the intensity of roasted pellets was greatly improved with the coke ratio of less than 1.5% and pellet alkalinity at 0.9.
考虑到当球团碱度提高时，生球在焙烧阶段易产生低熔点粘结相从而使单个球团强度达到1200n。
When the basicity increases, the fired pellet strength can be improved to 1200n because of the low-melting binding phase produced in the roasting stage.
以转炉污泥为原料，配入有机和无机复合结合剂，采用压制成型和低温焙烧的方法研制了高性能转炉污泥球团，并探索了影响球团强度的各种因素。
With the convertor sludge as raw material and with mixed binding of organic and inorganic binding agent, high quality sludge pellet was prepared by crumby pressing and low temperature calcination.
