Compared with other processes, such as pouring molten metal into an open mould, HPDC is fast and cheap.
与将液态金属注入开模的工艺等工艺相比，HPDC工艺很快，并且很便宜。

The proper pouring and shell mould temperature have been suggested, so that both satisfied microstructure and excellent mechanical properties of superalloy K423A can be achieved.
The influences of cooling rate of the mould, pouring temperature, nodularity and chemical composition on hardness of roll body were described, and the measures for solve problems were proposed.
