据《冶金科技报》1983年5月25日报道,武汉钢铁学院与下陆钢铁厂合作,于1983年2月,在试验室试验的基础上,进行了高精矿比添加稻谷壳的烧结工业试验。下陆钢铁厂现有烧结盘,真空度为170～400毫米水柱。在未添加稻谷壳时,配用20%精矿,成品率很低。添加稻谷壳后,精矿比由20%逐步增加到 According to “Metallurgical Science and Technology Newspaper” reported on May 25, 1983, Wuhan Iron and Steel Institute and the cooperation of the steel plant under the ground in February 1983, based on laboratory tests carried out high-concentrate ore than the addition of rice hull sintering industry test. Downland steel plant existing sintering plate, the degree of vacuum 170 ~ 400 mm water column. In the case of no added rice hulls, with 20% concentrate, the yield is very low. After adding rice husk, the concentrate ratio increased gradually from 20% to
