近几年来我国地方骨干钢铁企业烧结生产和技术改造工作取得了重大进步。1978年到1983年的五年中骨干企业机烧产量由724万吨增加到1030万吨,基本上消灭了土烧,烧结机由50台增加到67台,高炉熟料比由66%增加到80%;冷矿比重由42%上升到60%, In recent years, China’s major local iron and steel enterprises sintering production and technological innovation has made significant progress. During the five years from 1978 to 1983, the production of machine-made products by key enterprises increased from 7.24 million tons to 10.3 million tons, basically eliminating soil burning. The number of sintering machines increased from 50 to 67 and the blast furnace clinker ratio increased from 66% to 80%; cold ore proportion increased from 42% to 60%
