Abstract
Description
【発明の詳細な説明】 〈産業上の利用分野〉 本発明は連続鋳造用鋳型に関するものである。[Detailed description of the invention] <Industrial application field> The present invention relates to a continuous casting mold.
〈従来の技術〉
連続鋳造用鋳型は、その使用条件から鋳型上部では主と
して溶融金属に対する抜熱性が、鋳型下部では凝固シェ
ル即ち鋳片に対する耐摩耗性が要求される。<Prior Art> Continuous casting molds are required to have heat removal properties mainly for molten metal in the upper part of the mold and wear resistance against the solidified shell, that is, slabs, in the lower part of the mold due to the conditions of use.
