Abstract

"MéTODO DE FUNDIçãO E MáQUINA DE FUNDIçãO". O método de fundição da presente invenção é capaz de fazer com que o volume de um cabeçote alimentador seja pequeno e fazer a taxa de esfriamento do referido cabeçote alimentador ficar facilmente menor do que a de uma cavidade. o método é executado numa máquina de fundição que inclui um molde de fundição no qual um cabeçote alimentador é colocado entre uma entrada para metal e uma cavidade, e na qual o isolamento de calor do cabeçote alimentador é maior do que o da cavidade, de modo a tornar a taxa de esfriamento do cabeçote alimentador menor do que a da cavidade. O método compreende as etapas de: despejar um metal derretido na cavidade; fazer a reação dd metal derretido num composto desoxidante na cavidade, de modo a desoxidar uma pelicula de óxido formada sobre uma superficie do metal derretido, e complementar o metal derretido no cabeçote alimentador na cavidade quando o referido metal derretido na cavidade estiver solidificado e contraído."CASTING METHOD AND CASTING MACHINE". The casting method of the present invention is capable of making the volume of a feeder head small and making the cooling rate of said feeder head easily less than that of a cavity. the method is performed on a casting machine that includes a casting mold in which a feeder head is placed between a metal inlet and a cavity, and in which the heat insulation of the feeder head is greater than that of the cavity, so making the cooling rate of the feed head lower than that of the cavity. The method comprises the steps of: pouring a molten metal into the cavity; make the reaction of the molten metal in a deoxidizing compound in the cavity, so as to deoxidize an oxide film formed on a surface of the molten metal, and complement the molten metal in the feed head in the cavity when the said molten metal in the cavity is solidified and contracted.
