Embodiment 1

[0025] like figure 2 Shown, a kind of pressing bag process that prevents nodularizing agent sticking bag, comprises the following steps:

[0026] (1) Evenly lay iron filings or silicon steel sheets in the pit on one side of the dike-type casting bag as a layer, spread it flat, and hammer it firmly;

[0027] (2) Spread the nodulizer evenly on the first layer as the second layer, spread it flat, and hammer it firmly;

[0028] (3) Spread the inoculant evenly on the second layer as the third layer, flatten and hammer it;

[0029] (4) Evenly lay iron filings or silicon steel sheets on the three layers as four layers, spread them flat, and hammer them firmly. The thickness of the first layer is 20mm, the thickness of the second layer is 90mm, the thickness of the third layer is 50mm and the thickness of the fourth layer is 30mm .

[0030] Wherein, the embankment height of the embankment-type pouring ladle is 200mm; the ratio of the height to the diameter of the embankment-type p...

Abstract

The invention discloses a ladle pressing technology capable of preventing a nodulizing agent from sticking to a ladle. The ladle pressing technology comprises the steps of (1) uniformly laying scrap iron or silicon steel sheets in pits in one side of a dam type pouring ladle dam as a first layer, carrying out leveling, and carrying out compacting through hammering; (2) uniformly laying the nodulizing agent on the first layer as a second layer, carrying out leveling, and carrying out compacting through hammering; (3) uniformly laying a nucleating agent on the second layer as a third layer, carrying out leveling, and carrying out compacting through hammering; and (4) uniformly laying scrap iron or silicon steel sheets on the third layer as a fourth layer, carrying out leveling, and carrying out compacting through hammering, wherein the sum of the first layer thickness, the second layer thickness, the third layer thickness and the fourth layer thickness is not larger than the height of the dam type pouring ladle dam. According to the ladle pressing technology capable of preventing the nodulizing agent from sticking to the ladle provided by the invention, the problem that the nodulizing agent is liable to soften and stick to the bottom of a pouring ladle under high-temperature baking is solved.

Description

technical field [0001] The invention relates to a packing process, in particular to a packing process for preventing nodularizing agent from sticking to the bag. Background technique [0002] Spheroidizing treatment is a process of treating alloy liquid during casting of cast iron to obtain spheroidal graphite cast iron, thereby improving the mechanical properties of cast iron. Ductile cast iron has high strength, good plasticity and toughness, and low production cost Convenient and widely used in industry. Spheroidization treatment is required in the production of nodular cast iron. There are many common spheroidization treatment processes, such as the flushing method, the bell jar method, and the wire feeding method. Among them, the flushing method is the most widely used spheroidizing process at present. There is no special requirement for the molten iron ladle. One layer of inoculant, three layers of iron filings. [0003] The Chinese patent with application number 20...
