一、前言高炉操作中,煤气分布与送风制度、装料制度关系密切。送风制度决定了煤气的原始分布,装料制度可以调节煤气的分布状况。宝钢高炉的实践表明,煤气分布以中心流比较发展,边沿流适当发展为理想的分布。煤气分布调整的基本考虑有以下三点。 1.下部调节的送风制度对于气流的合理分布和炉缸工作的好坏起着决定性作用。所以,在调整煤气分布时,首先要考虑送风制度(风量,风温、湿份、喷吹量,风口面
First, the preface blast furnace operation, gas distribution and air supply system, charging system is closely related. Supply air system determines the original distribution of gas, charging system can regulate the distribution of gas. The practice of Baosteel blast furnace shows that the distribution of gas is relatively developed in the center flow, and the edge flow appropriately develops into an ideal distribution. The basic consideration of gas distribution adjustment has the following three points. 1. The lower regulation air supply system plays a decisive role in the proper distribution of airflow and the performance of the hearth. Therefore, when adjusting the gas distribution, we must first consider the air supply system (air volume, air temperature, humidity, injection volume, tuyere surface
