在高炉生产中,常有这种情况:不论装料制度如何改变,收效往往不大;有时送风制度改变,也得不到予期效果. 有时,由于装料制度或送风制度改进后,生产取得一定进步,在此基础上再做调剂,常常会收到更大的效果.这是因为装料制度和送风制度是互相影响的.要想达到较高生产水平,两者必须互相适应.这种互相适应,可以概括为:如装料制度以疏导中心为主,下部能够接受较高风速;如装料制度以发展边缘为主,则下部能接受的风速将要降低.因此,当高炉风速较低,炉缸风口循环区较小,炉缸初始煤气分布边缘较多时,对于大、中型高炉来说,此时在装料制度上不应过急加重边缘负荷,而应逐步加重,并疏导中心,防止边缘气流被突然堵塞,煤气失去正常通路,破坏高炉顺行;如下部中心气流发展,也不能一次堵塞中心气流,在适当疏导边缘后再相应增加中心负荷,保持煤气通畅,维持高炉顺行. In the production of blast furnaces, it is often the case that no matter how the charging system is changed, the effect is usually not large, sometimes the air supply system is changed, and the expected effect can not be obtained, and sometimes, due to the improvement of the charging system or air supply system, Some progress will be made and adjustments will be made on the basis of this, and we will often receive even greater results because the charging system and the air supply system are mutually influential, and if we want to reach a higher level of production, the two must adapt to each other. This adaptation can be summarized as follows: if the charging system is dominated by diversion centers, the lower part can accept higher wind speeds; if the charging system is mainly developed at the edge, then the lower acceptable wind speed will be reduced, therefore, when the blast furnace wind speed Lower, the hearth tuyere circulation area smaller, the initial gas distribution edge of the hearth gas cylinder more, for large and medium-sized blast furnace, the loading system should not be too heavy edge load, but should be gradually increased, and to divert Center, to prevent the edge of the airflow was suddenly blocked, the gas lost its normal access, destruction of blast furnace along the line; as the following center of the development of air flow, it can not plug the center of the airstream, and then appropriate to ease the edge and then increase the center load, maintaining gas patency Blast furnace along the line.
