How To Improve The Yield Of Machinery Casting Part?

How to improve the yield of Machinery Casting Part?
 Analysis and research on the defects of Machinery Casting Parts is one of the key technologies to improve the yield of Machinery Casting Parts. However, its difficulty is not small. Mainly in:
① knowledge, such as alloy, casting process, modeling materials, casting equipment and production process testing and other aspects of knowledge.
② defects in the formation of Machinery Casting Part defects, a defect can be caused by a variety of reasons, and one cause may cause several defects.
(3) the constraints of technical measures, such as the use of a measure, can prevent a type of defects, but may lead to another defect.
④ influencing factors difficult to control, such as raw material quality, air temperature and humidity.
In order to reduce the defects of Machinery Casting Parts and improve the yield of Machinery Casting Parts, it is necessary to effectively control the defects of Machinery Casting Parts. The accurate judgment of the defect is a prerequisite for solving the defects of the Machinery Casting Part. Therefore, it is necessary for the foundry to understand the various means of the defect, including the general and special analysis means to determine the type of defects, analyze the causes of their occurrence, and then put forward preventive measures, and from the technical and management to be implemented. It is noteworthy that, despite the same type of defects, but for different cast alloy Machinery Casting Parts, the formation of the reasons and the prevention measures are different.
 The concentrated shrinkage produces the final solidified area of the Machinery Casting Part, so determining the position of the shrinkage is the area where the final casting of the Machinery Casting Part is determined. In practice can be determined by solid phase line method.
For the alloy with a very small crystallization temperature range, the solidification front can be regarded as a dividing line of solid-liquid, and it is also an isotherm, called a solidus. The so-called solid-phase method, that is, in the Machinery Casting Part section from the cooling surface began to layer inward to draw the solid line, until the narrowest section of the fixed line contact so far. At this point, such as solid phase is not connected to the place, is the final solidification of Machinery Casting Part front, that is, the location of the shrinkage.
Determination of the position of the shrinkage of the machined part of the I-shaped cross section by the solidus method, and the position of the shrinkage of the actual Machinery Casting Part. If the cold cast iron is placed on the bottom of the Machinery Casting Part, the solidus is moved up and the shrinkage is concentrated in the upper part of the Machinery Casting Part due to the increase of the cooling rate. If the cold iron is appropriate and the upper part is designed, So that the Machinery Casting Part within the non-shrinkage.
If the Machinery Casting Part on the structure of the two walls of the intersection of the inscribed circle is greater than the thickness of the intersection of each wall, where the solidification of the latest, but also produce shrinkage of the site, here called hot section. In addition, the Machinery Casting Part thick wall and near the runner, but also solidification of the slow heat section.
 Although China's Machinery Casting Part has made great progress, but its casting materials in the quality, variety, quantity, in the overall technical level and enterprise management, with the world's advanced level there is a big gap. Only to establish a high quality, less pollution, relatively stable, orderly supply, highly developed casting materials market, in order to adapt to China from the casting power to the casting power forward needs. Therefore, China's Machinery Casting Part in the next period to achieve the three goals:
First, the completion of the growth mode by the labor, resource-intensive to the technology capital-intensive changes from extensive pollution to green intensive type of change, the product quality, variety, the number of the world's advanced level, the proportion of high-quality materials Increase, the entire Machinery Casting Part plant production efficiency, economic benefits doubled; environmental pollution has been effectively managed, initially built with the environment coherent China casting materials industry system.
Second, the formation of a number of reasonable structure, the overall level of high combination of research and development and education and training base, can continue to transport professionals to the enterprise, and constantly develop high-quality, high-grade casting new varieties of materials to meet the growing demand for Machinery Casting Part The need to gradually increase the intensity of technology exports.
Third, to complete the industrial structure adjustment, out of a number of low level of technology, product quality is poor, serious pollution, poor economic efficiency of small precision casting plant, relatively concentrated, to achieve "professional, large-scale" production. In particular, to the emergence of one or two well-known enterprises to compete with the world's leading enterprises, their high level of technology, sophisticated technology, well-funded, advanced management level, can continue to provide high-end market, high-quality casting materials, market High rate.
