铸件热处理加热速度由以下因素决定。

①铸件的化学成分:高精密铸造件含碳量与合金元素含量较大时,导热性就差,其加热速度应选择较小,否则,加热速度过快,则必引起铸件较大热应力。

故铸件的加热速度应随含碳量及合金元素的增加而减小。

②铸件壁厚:当铸件壁厚很大时,如果加热速度过快,则铸件内外温差也就愈大,熔模精密铸造件热处理时其加热过程中的加热速度应小一些,而薄壁铸件应选大一些。

③铸件形状:铸件的形状愈复杂,断面厚薄愈不均匀,加热时也愈易产生过大的热应力。因此,对形状复杂的断面,厚薄不均匀的铸件,其加热速度应慢一些,反之,形状简单的铸件其加热速度可快一些。

通常的加热速度为每小时200~400℃。
