  • Method for casting high-power wind turbine base with ductile iron
    Patent number: 8096346
    Abstract: A method of casting a base of high-power wind turbines with low-temperature nodular graphite iron, using furan resin sand as the mold sand and having no risers or chills in the mold. The mold undergoes microseismic compaction and has no chills risers. The parting face of the mold is perpendicular to the ground. The molten iron in the mold is solidified evenly. Therefore, shrinkage holes and disperse shrinkages base are reduced greatly and the dregs and air are discharged easily for the base. The pouring system designed together with a reasonable pouring rate and time make the filtering system useful for blocking dregs.
