Problems solved by technology

The flushing method is easy to operate, but its magnesium absorption rate is low, and the temperature of the spheroidizing treatment is much lowered, which is easy to cause slag inclusion and serious pollution to the environment; The amount of input is small, the degree of industrialization is high, the labor load of the operator is greatly reduced, and the influence of human factors can be eliminated, and the quality is stable. However, the input cost of equipment for feeding wire balls is relatively high, and the cost per ton of molten iron is also higher than that of the flushing method. high

Abstract

The invention discloses a spheroidizing device and spheroidizing method of spheroidal graphite cast iron, is suitable for smelting and spheroidizing of the spheroidal graphite cast iron materials, andsolves the problem of the high spheroidizing cost of the spheroidal graphite cast iron by using wire feeding method. The spheroidizing device comprises a storage tank, a nitrogen source and a pouringladle; the storage tank is used for storing the spheroidizing material, a pressure monitoring device is arranged at the upper end of the storage tank, a feeder is arranged at the lower end of the storage tank, and the storage tank is conencetd with the nitrogen source through a hose; and the pouring ladle is connected with the storage tank through a feeding hose, so that the spheroidizing material is fed from the storage tank to the pouring ladle, one end of the feeding hose is connected to the feeder, and the other end of the feeding hose is connected to the spheroidizing opening at the lower end of the pouring ladle. According to the spheroidizing device, through the way of pneumatic conveying of the spheroidizing material, the safety risk of artificial adding of the spheroidizing material is avoided, the problem of uneven spheroidizing caused by the fact that the spheroidizing material is sprinkled from the top of stirring is solved, and the effect and efficiency of the whole spheroidizing developing are improved.

Description

technical field [0001] The invention relates to the technical field of nodular cast iron smelting, in particular to a spheroidizing treatment process of nodular cast iron. Background technique [0002] Ductile iron is one of the main materials of iron castings. The methods to obtain ductile iron mainly include punching method and wire feeding method. The flushing method is easy to operate, but its magnesium absorption rate is low, and the temperature of the spheroidizing treatment is much lowered, which is easy to cause slag inclusion and serious pollution to the environment; The amount of input is small, the degree of industrialization is high, the labor load of the operator is greatly reduced, and the influence of human factors can be eliminated, and the quality is stable. However, the input cost of equipment for feeding wire balls is relatively high, and the cost per ton of molten iron is also higher than that of the flushing method. high.
