連続鋳造過程における温度場および凝固シェルの弾塑性応力場のシミュレーション

抄録

An analytical method to simulate the temperature and the stress fields in a continuous casting slab under steady operating conditions is presented. The heat conduction equation incorporating heat generation due to solidification was solved by finite element method to obtain the spatially steady temperature distribution when considering material flow. Elastic-plastic stresses in the solidified shell were also evaluated. A parameter study was carried out in order to obtain the optimal operating condition such as shell thickness, site of crater end, and stress distribution as functions of the casting speed and cooling condition.
