冲天炉采用二次送风后,对节约焦碳,提高鉄水温度和保证产品质量,起了很大作用。为了使这一经验得到迅速的推广,在介绍这些厂经验的同时,提出以下几点意见,供大家参考。 1.从这些经验看来,“二次送风”的办法冲天炉可以采用,三节炉也可采用;有前炉的可以采用;没有前炉的也可采用;直筒形炉子可以采用,曲线形炉子也可采用。总之,只要摸清炉子的特性,就能设法让它为社会主义建设作出更大的贡献来。 2.二次送风的目的是使还原带内的一氧化碳燃烧,不希望焦炭燃
Cupola after the second air supply, the coke savings, improve water temperature and ensure product quality, played a significant role. In order to promote this experience rapidly, while introducing the experience of these plants, we put forward the following opinions for your reference. 1. From these experiences it seems that the method of “secondary air supply” can be adopted in the cupola furnace and the three-stage furnace can also be used; the front furnace can be used; the furnace without the front furnace can also be used; the straight tube furnace can be adopted; Stoves can also be used. In short, if we can find out the characteristics of the stove, we can try to make it make a greater contribution to the socialist construction. 2. The purpose of the secondary air supply is to make the carbon monoxide in the reduction zone burn without burning coke
