为了有效利用废塑料,日本钢管公司从1996年10月起,在京浜1号高炉进行了高炉喷吹废塑料。研究了在实际高炉喷吹废塑料时的炉内行为。试验用的废塑料是粒度为0.2～1mm、-10mm的聚乙烯,每个风口的塑料喷吹量为12～40kg/min(约等于80～240kg/thm)。喷吹废塑料时,从风口的后方用高速摄像机摄像,用推进探头(FVP),在炉内径向采集了
In order to make effective use of waste plastics, Nippon Steel Pipe Co., Ltd. carried out the blast furnace injection of waste plastic from No.10 blast furnace in Beijing since October 1996. The behavior of the furnace in the actual blast furnace injection of waste plastics was studied. The waste plastic used for testing is polyethylene with a particle size of 0.2-1 mm and a thickness of -10 mm. The blowing amount of plastic for each tuyere is 12-40 kg / min (equivalent to about 80-240 kg / thm). At the time of blowing waste plastics, the camera was photographed with a high-speed camera from the rear of the tuyere, and with a propelling probe (FVP), it was collected radially in the furnace
