The chill depth has the power-law relationship to the surface hardness of the melting zone. The larger the chill depth, the higher is hardness value. 白口层深度与熔区表面硬度成指数关系,白口深度越大,则硬度值越高。
The hardness and depth of chill layer on the roller outer surface can be raised with adding trace Bi into liquid Fe in centrifugal casting. 离心铸造时在铁水中加入微量的铋,可以提高滚筒外壳冷硬层的硬度和深度。
