Study on Unidirectional Solidification of Slab Ingot for Special Heavy Plate

Abstract:

Unidirectional solidification is a method of producing slab ingot for special heavy plate, when compression radio is more than 2.5, internal soundness of slab ingot is assurance, and the nature of Z orientation and percent of pass through supersonic flaw detecting are increased. Products are used in oil drilling platform in ocean ,separator of steam turbo-alternator with more than 0.6 million kW, anchor gate of large-scale hydropower station, shell of nuclear power plant, armoured plate of aircraft carrier. According to dissection on 28t large-sized slab ingot, simulation experiment of crystal, and analogy calculation of heat transfer and coagulation with CFX software, histology features and key to manufacturing technology of large-size unidirectional solidification slab ingot were mastered.
