The annealing process of multiple inoculations metal-mould malleable cast iron is compared with common inoculation one,the first stage graphitization annealing time is decreased from 45 minutes to 25 minutes,and the second stage graphitization annealing time is shortened from 350 minutes to 80 minutes.

The effects of several compound inoculants on the mechanical property, processability and sensibility of the gray cast iron used in cylinder body are investigated in this article.

Aimed to develop the mechanical properties index, the content of this paper is mainly about boron gray cast iron, which melts with boron pig iron and is inoculated by the SiSr and SiFe compound inoculants.

By means of V_(slag) + Ti + Zn,the composite inoculation to the high-Cr white cast iron can be performed.

By adjusting contents of both the graphitizing elements and elements of stabilizing system and adopting Si-Mn-Sn composite inoculation instead of Cu-alloying,it was achieved that the free carbide was reduced,pearlite fraction was increased and the mechanical properties were increased.
