Production manner of continual casting roller and aforementioned continual casting roller for melting bus casting

摘要

This invention, the melting bus (especially, the steel melting bus) regards the continual casting roller for casting. This casting roller, the roller barrel which consists of the metallic materials (2) and, is provided on that, formation of the metallic materials make which possess the hardness whose the aforementioned roller barrel (2) is higher than hardness possesses (4). As for the continual casting roller which is due to this invention, service life becomes longer, also use property is improved. This, rather than the free surface (5) in the field, extends to the whole of thickness it adjoins the roller barrel in the field where (2), is achieved hardness compared to the formation which becomes low by providing (4).
