连铸板坯的“鼓肚”、应变与设备工艺参数的关系

THE DEPENDENCE OF BULGING AND STRAINS OF CONTINUOUS CAST SLABS ON PARAMETERS OF OPERATION AND EQUIPMENT

为防止板坯连铸中的缺陷,铸机的设计及生产必须考虑到控制铸坯上的应力和应变。本文给出板坯宽面“鼓肚”的蠕变解,蠕变“鼓肚”的近似计算式以及坯壳内外表面的应变计算式。为铸机设计和生产提供重要理论依据。

To prevent defects of continuous cast slabs, it must be considered to control the stresses and strains in slabs in casting machine design and operation. In this article, the calculated result of the creep bulging and the equations tc calculate strains of inter- and outer-surfaces of cast slabs are given. It provides an important theoretical basis for casting machine desigen and operation.
