Abstract
The tensile strength of casting ring liners was measured and the relationships between bulk density, rate of vacant space and compression strain were evaluated. Strength was determined for fourteen ceramic liners (A : rockwool type, B : ceramic fiber low temperature type, C : ceramic fiber standard type, D : ceramic fiber low temperature-standard type, E : kaolin type). Dumbbell type test specimens were prepared, and the width of the narrow part was 10 mm, and the length was 20mm (n=5). The tensile strength of E group showed a remarkably large value of 12.73 MPa, and in the other 13 products, it ranged from 0.27 to 3.01 MPa. There was a positive correlation between tensile strength and bulk density, and negative correlations between tensile strength and both rate of vacant space and compression strain.
