Abstract
PURPOSE: To enable the cast iron pipe having required ferrite structure without annealing by adding spheridizing agent to molten metal on the way of a molten metal pouring trough.
CONSTITUTION: A reaction chamber 6 is provided on the lower side of the mid- portion of a molten metal pouring trough 4 of a centrifugal casting mold and before the molten metal is passed a suitable amount of spheroidizing agent having beforehand been calculated according to molten metal amount is beforehand disposed. Further, the upper opening part is held put with a cover plate 7. At the time of pouring, the spheroidizing agent is added in the reaction chamber 6 while the molten metal is being passed on the trough 4, whereby the required spheroidization is applied. This method enables large spheroidization effect to be obtained through addition of a small amount of the spheroidizing agent. Hence, the production of defects, etc. owing to dross and the hampering of ferritization owing to the induction of pearlite on account of excessive addition are prevented and the required ferrite structure is obtainable as cast.
