Remanufacturing Technology in Continuous Casting Core Equipment and Its Application

Remanufacturing of continuous casting core equipment is an important direction for efficient development of green steel. The failure mode of continuous casting mold and roller was described. Surface technology and structural design techniques for continuous casting core equipment were introduced. Thermal stability, wear resistant and life of all type coatings were analyzed. Finite element analytical techniques were used to analyze the structure and service condition of continuous casting mold and roller. Designs were optimized and matched the excellent surface technology to improve the overall life of the continuous casting equipment. Practice show that the performance and technology of continuous casting equipment are improved through advanced surface technology, design and management of the remanufacturing engineering system. The life expectancy and retirement period are extended and the quality and added value are improved, resulting in good social and economical benefits.
