高炉上有关炉气、炉料运动的研究可以帮助人们了解熔炼机构并制定高炉的改进方案。这里我们在一个容量为55立方米的试验高炉上,利用放射性示踪原子的方法进行炉料下降速度的测定试验;同时利用放射性的稀释原理,可以测出炉底的剩铁量。此外,从几次不同时间的试验所测得剩铁量的改变情况,可以计算出炉底耐火材料的侵蚀速度。这样,炉料下降速度、炉底剩铁量和炉底耐火材料侵蚀速度虽然是属于三种不同的研究课题,而可以通过一种试
Research on the furnace gas and charge movement on the blast furnace can help people understand the melting mechanism and make improvements to the blast furnace. Here we are in a test capacity of 55 cubic meters of blast furnace, the use of radioactive tracer atom method to test the rate of decline of the charge; the same time, the use of radioactive dilution principle can be measured at the bottom of the iron residue. In addition, the rate of erosion of the bottom refractories can be calculated from the changes in the amount of iron remaining from several tests at different times. In this way, the rate of charge down, the amount of iron remaining furnace bottom and refractory erosion rate of bottom although belonging to three different research topics, and through a test
