为满足宝钢高炉喷吹煤粉采用计算机控制时对煤粉连续计量精度达到1～2%的要求,由冶金部钢铁研究总院、重庆钢铁设计研究院、宝山钢铁总厂共同研制了一套模拟宝钢高炉一个风口喷煤量(每小时1000kg)的串联罐硬连接冷态试验装置,并在冶金部钢铁研究总院建成,经过两年试验,已达到了设计要求,于1986年12月通过冶金部组织的技术鉴定。硬连接串联罐喷煤装置,其上罐与中间罐仍为软连接,而中间罐与下喷吹罐之间则
In order to meet the requirement of continuous measurement accuracy of 1 ~ 2% for pulverized coal when controlled by computer in Baosteel blast furnace, a set of simulations were jointly developed by the Steel Research Institute of the Ministry of Metallurgy, Chongqing Iron & Steel Design Institute and Baoshan Iron & Steel Plant Baosteel Blast Furnace a tuyere coal injection (1000kg per hour) series cans hard connection cold test device, and the Ministry of Metallurgical Iron and Steel Research Institute completed, after two years of testing, has reached the design requirements, in December 1986 through the metallurgical Ministry of organization of technical appraisal. Hard-connected tandem can coal injection device, the upper tank and the intermediate tank are still softly connected, while the intermediate tank and the next between the injection tank
