Improvement in Service Life of Continuous Casting Mold

Kichio Tada, Satoshi Kasai, Akira Ichihara, Hiromu Onishi
Synopsis :
The high quality continuous casting mold has been increasingly required by continuous casting techniques such as high speed casting, automatic width control, and sequential casting of different steel grades. The authors have developed several equipment techniques to establish high reliability and long life of the continuous casting mold, as follows: (1) clamp force control system depending upon slab width which ensures against scratch forming on the mold due to automatic width changing and shrinking of the narrow face edge at meniscus in width directions, (2) high heat and wear resistant Ni-Fe and Ni-W-Fe mold plantings which realize prolongation of the mold life, (3) uniform cooling system based on heat transfer and the stress analysis which ensures reliable and continuous operation, (4) facility evaluation system of the mold based on variable operation factors, which prolongs the mold life and enhances accuracy in estimation of the service life of the mold.
