Abstract

PURPOSE:Not only to lessen a variation of the sphering rate in the length direction of the casting piece but also to produce the spherical graphite cast iron of excellent quality by holding its high rate, by adding the graphite sphering agent or the inoculative agent to molten metal in the retaining furnace of the cast iron continuous casting machine, and drawing it out. CONSTITUTION:The cast iron of low P and low Mn which has been carefully selected by the 8t low frequency electric furnace is dissolved, it is poured into the ladle 11 at 1450 deg.C, and also the graphite spher is performed by adding the graphite sphering agent such as Fe-Si-Mg alloy, etc. by 1.4-1.8% to the molten steel 6, and stirring it 12 enough. Subsequently, the inoculative agent such as Fe-Si, etc. is added at the rate of 0.2-0.6% to the molten steel 6 which has been subject to graphite spheroidizing, and it is stirred enough in the same way. After that, the object spherical graphite cast iron is produced by drawing out the casting piece 7 from the molten steel 6 through the graphite die 3 which is installed to the furnace 1. Also, 4, 8, 9 and 10 in the figure show the cooling box of the die 3, the pinch roll for drawing out the casting piece 7, the cutting machine which notches the casting piece 7, the breaking machine, respectively.
