摘要
In this paper, the coal ash /refractory samples were sintered in the furnace at certain temperature for 20h. Then three tests were made by visual observation method, XRD analysis of the coal ash and electromagnetic vibration of the coal ash/ refractory samples respectively in this paper to determine the critical temperature of three coal ashes on the corundum based refractories. Finally, the result shows that the electromagnetic vibration test is the most effective method with a better discriminabiltity on slagging intensity to determine the critical temperature of the coal ash slagging on the refractory. And furthermore, it advances a new and reliable method to determine the critical temperature on the refractories.
