一、前言端出料推钢式连续加热炉在我国已广泛采用。这种加热炉在工艺操作上有许多优点;但是,从热工观点看我国普遍应用的这种炉型存在着许多严重缺点。首先,由于尚未很好解决炉门密封问题,在温度几何压头作用下及端部烧咀火焰喷射下,使端出料门形成较高的负压,从炉门吸入大量的冷空气,带来降低端头钢坯温度,增加金属氧化烧损,降低炉膛热效率等缺点。其次,从出钢下滑点到端墙之间的距
First, the foreword Push out the end of steel-type continuous heating furnace has been widely used in our country. This furnace has many advantages in process operation; however, there are many serious shortcomings of this type of furnace, which is commonly used in our country from a thermal point of view. First of all, since the door sealing problem has not been solved well yet, under the influence of the temperature geometric indenter and the end burning nozzle flame jet, the end discharging door is formed with a higher negative pressure and a large amount of cold air is sucked in from the door. To reduce the temperature of the end of the billet, increasing the oxidation of metal burning, reducing furnace thermal efficiency and other shortcomings. Second, from the tapping point to the distance between the end walls
