Abstract
Recently, the study of coreless-type low frequency furnace is being made increasingly, but little work has been done on the erosion of lining. With this in mind, authors have made the study of the dry process lining for 1.5t low frequency induction furnace to clarity the actual condition of erosion and study the method of understanding it by measuring the degree of erosion and comparing the characteristics by using the tool. The results are as follows :
(1) Concave or convex deformation is remarkable especially on the basic lining.
(2) The degree of erosion on the bottom is larger than that on the wall. The difference in between the upper and the lower wall is not remarkable. However, the erosion on the bottom erosion increases correspondingly to the number of melting.
(3) A new method of study in which the measured point is moved from the top to the bottom in a spiral by a tool and the values are put in increasing order was devised. The merit of this method is in showing the degree of the changes in the lining configuration by the whole gradient of the curve and the movement of the cross point on the 0-line.
