一、网形图的回顾网形图是将冲天炉操作中的主要参数用图来表示。图上的参数是指熔化率、碳耗率(或铁碳比)、送风强度和铁水温度。网形图帮助冲天炉操作者确定达到一定的铁水温度、熔化率所需要的焦耗率和送风强度。根据某一个冲天炉的数据制成的网形图,只适用于该冲天炉,但总的图形刘于大多数冲天炉都相似。在炉料中加入碳化钙、热风、风口喷氧和炉膛形状都可使总的图形改变。一旦得出某个冲天炉 First, the review of the grid chart The grid chart is the main parameters of the cupola operation with a map to represent. The parameters on the graph refer to the melting rate, carbon rate (or iron-carbon ratio), blast strength and hot metal temperature. The grid helps the cupola operator determine the rate of burn-in and blast strength required to reach a certain hot metal temperature, melt rate. The grid graph based on the data from one cupola only applies to this cupola, but the overall graph is similar to most cupolas. In the charge of calcium carbide, hot air, tuyere oxygen and furnace shape can make the total graphics change. Once you get a cupola
