Abstract

PURPOSE: To enable the cast iron pipe of required quality to be obtained without annealing by casting the molten metal contained with the limited amount of Mg in a centrifugal casting mold which is dry coated with low Mg alloy powder.
CONSTITUTION: Coating of the thickness corresponding to the thickness of cast iron pipe is applied to the inside surface of the mold and further the low Mg alloy powder containing about 3W6% of Mg is dry coated on the inside surface thereof. Molten cast iron containing Mg; 0.02W0.03% is poured into this centrifugal casting mold. At the centrifugal casting of this molten metal, spheroidization is perfected by a small amount of Mg contained in the molten cast iron and the Mg in the dry coating and a small amount of this Mg per se assists graphitization together with Si, thus required ferrite structure becomes obtainable as cast. At the same time, troubles owing to addition of excessive Mg are improved.
