The creeping graphite cast iron described in this invention can be made by smelting V-Ti pig iron or ordinary pig iron as raw material, using RE-ferrosilicon as major metamorphosing agent and RE-Mg-ferrosilicon as minor metamorphosing agent. The mould for glass bottle made by this material and used on high speed bottle-manufacturing machine has improved oxidation-resistance, growth-resistance and wear-resistance, and thus enhances the smooth finish of glass products, service life of the mould, and notably the economic results. |
