In unidirectional precision casting of gas turbine blades, radiation is governing heat transfer between susceptor wall and ingot wall. Authors have proposed the method of calculating a form coefficient at high speed by introduction of an approximation formula and the plne scanning method. In this paper, the heat transfer calculation which used the view of the zone-method shoots, the method of simpligying and radiosity calculation analysisportion is proposed, and it is investigating about the accuracy with improvement in the speed of radiation heat transfer analysis using an easy model. Consequently, compared with the conventional analysis method, the ratio of sped dropped to 1/3 with the strict solution and the error of several perent.
