Description

Lid method balling device

Technical Field

The utility model belongs to nodular cast iron casting production field especially relates to a lid method spheroidizing device that nodular cast iron casting was used.

Background

In the casting production of nodular cast iron, a molten iron spheroidizing process is one of key technologies for producing nodular cast iron parts. The spheroidization effect of the molten iron is directly related to the performance of the nodular iron castings, and is one of the most critical factors influencing the quality of the castings. Since the advent of spheroidal graphite cast iron, research on the process of spheroidizing molten iron has never been stopped with the development of spheroidal graphite cast iron. The spheroidization process directly influences the height and stability of spheroidization quality, the simplicity and the complexity of process operation, the investment of equipment, the height of treatment cost and the quality of operating environment. With the continuous and deep research, the molten iron spheroidization process is greatly developed, and various spheroidization processes in different forms are formed, wherein the spheroidization process by the cover method is an advanced nodular cast iron production process at present.

In recent years, the spheroidizing process by the capping method is more commonly applied in Europe and America, and a few domestic manufacturers are successfully applied. The process has all the advantages of simplicity, convenience and practicability of a common rushing-in method, and also has the advantages of small adding amount of a nodulizer, good nodulizing effect, stable nodulizing quality, small burning loss of alloy elements, small environmental pollution, conformity with national policies of national environmental protection and the like. The existing spheroidization technology by a cover-ladle method mainly has the following forms:

1. a fixed covering method: the ladle cover and the ladle are fastened together, the nodulizer is added into the ladle through the hole on the ladle cover, and slag removing treatment is not needed after the nodulizing treatment. Its advantages are simple process and no need of on-site modification. However, the method requires relatively pure molten iron, so that each link in production needs to be strictly managed, the labor intensity of dismounting and mounting the ladle cover each time is high, and the problem of high slag content in the molten iron may exist when each ladle is used to the later stage of the specified times.

2. Manual cap removal method: the ladle cover can be covered before the spheroidization reaction, and the ladle cover is taken down after the reaction is finished and then is subjected to slag skimming and casting. The method is simple, but has poor labor conditions, and is a temporary example for some medium and small foundries.

3. The method of lifting (putting down) the bag cover by itself: the ladle cover and the ladle beam are matched together, and the lifting function of the ladle cover is realized by adding a specific mechanism on the molten iron ladle. The device has the defects that the structure of the used equipment is complex, the treatment ladle needs to be specially manufactured, different ladle beams need to be lifted in the treatment process to achieve the purpose of opening and closing the ladle cover, iron adhesion easily occurs, and the lifting of the ladle cover is influenced.

4. A forklift (crane) cap taking method: adding the nodulizer into the ladle, covering the ladle cover by using a forklift (crane), taking down the ladle cover by using the forklift (crane) after the reaction is finished, and then slagging off and pouring. In order to facilitate production, some factories place the ladle cover on a fixed support on the wall, and the ladle is conveyed to the fixed support by a fork (crane) truck to automatically remove the ladle cover. The method has smooth and tacit operation in factories, but the ladle is filled with the molten iron when the cover is removed, the ground personnel is required to cooperate with the operation, and the safety is poor.

5. Rotary platform method (cover process equipment system installed on rotary operation platform): the system is used for lifting, falling and swinging the spheroidizing ladle top cover, and simultaneously, the system also comprises a group of ground rotating disc systems. The system can maximize the production efficiency and even control the production rate by the melting rate, but the system needs larger ground space, is suitable for a newly-built casting workshop and is not suitable for the transformation of an old workshop.

The methods have the defects of troublesome operation or difficult overcoming in the using process, so the methods are difficult to popularize and apply.
