方坯高碳鋼連鑄中心縮孔模型及其應用

Models for Central Pipe Formation in Continuously Cast High Carbon Billet and Its Application

摘要: 通過物質平衡原理討論并新建立了計算方坯中心縮孔的數學模型.根據對數學模型的推導,給出了確定噴水強冷區的位置和確定鑄坯表面與鑄坯中心冷卻速率比值G的方法.

Abstract: The updated mathematic models for calculation of the central pipe formotion in continuous cast billet are built up, based on the material balance and the previous published models. From derivation of models the methods for determining both the position of water cooling zone and ratio of the cooling fates of the surface against the center, G are also given out.
