摘要

Shougang Jingtang Iron and Steel plant has built the new generation sinter plant with two 500 m~2 sintering machines at Caofeidian Port, the thought of Metallurgical Process Engineering was led into, and the ordering, coordinated, efficient, continuous production of sinter manufacturing processes were achieved. Whose overall design adopted advanced, proven process technology and large-scale equipments, which broke through long flow layout in traditional metallurgical projects and achieved short flow with compact arrangement. Widening side plate of sintering machine and annular cooler were used to create conditions for increasing production capacity, lowering energy consumption of unit production. According to the concept of recycling economy and energy saving, the high-temperature exhaust heat of annular cooler was recycled, the iron and carbon waste and waste water were dissolved, which gained sinter production energy conversion, by applying dense phase pneumatic dust conveying technology, the secondary pollution of dust was avoided, the concentration of SO_2 emission was below 47 mg/Nm~3 in the flue gas. Through adopting deep bed sintering, since producing in May 2009, the equipments ran smoothly with sintering bed depth reached 860 mm in sintering production, qualification rate of sinter ores reached 99.71%, drum index was 81.79%, and the energy consumption of process was 47.70 kgce/t, which attained first class domestically and internationally advanced level.
