Abstract
The invention relates to the technical field of glass molds, in particular to an alloyed gray cast iron glass mold and a preparation method thereof, and the alloyed gray cast iron glass mold is prepared from the following raw materials in percentage by weight: 3.50-3.65 wt% of C, 1.90-2.10 wt% of Si, 0.50-0.70 wt% of Mn, less than 0.08 wt% of S, less than 0.30 wt% of P, 1.00-1.30 wt% of Ni, 0.36-0.60 wt% of Cr, 0.36-0.50 wt% of Mo, less than 0.05 wt% of V, less than 0.08 wt% of Ti, less than 1.0 wt% of Cu and the balance of Fe and inevitable impurities. By adding a proper amount of alloy elements into the gray cast iron, the wear resistance, the thermal conductivity, the oxidation resistance and the thermal fatigue performance can be improved; meanwhile, growth and expansion of cracks can be effectively prevented, and the service life of the material is prolonged.
