The Principle Of Integrated Casting Of High-Strength And High-Toughness ZDL205A

The process of casting ZDL205A ZDL114A is to smelt metal aluminum to make a mold, and fill the mold with the molten metal under the action of gravity, pressure, centrifugal force, electromagnetic force and other external force fields. After solidification, the shape and performance of the casting are obtained. One of the main forms of metal parts and blanks. Aluminum casting is a method of forming liquid aluminum metal.

1. According to the different filling conditions, the production process of castings can be divided into gravity casting, pressure casting, centrifugal casting, etc. According to the casting molds forming the castings, it can be divided into sand casting, metal casting, investment casting, shell casting, ceramic casting, lost foam casting, magnetic casting, etc. Traditionally, other casting methods that are different from the sand casting process are collectively referred to as "special casting". Sand casting is widely used, and the castings produced by sand casting in the world account for more than 80% of the total output of castings. Sand casting can be divided into manual molding and machine molding. The quality (quality) of castings directly affects the quality (quality) of mechanical products. Improving the level of casting production technology is an important guarantee for the upgrading of mechanical products and the development of new products. It is one of the keys for the machinery industry to adjust product structure, improve production quality (quality) and economic benefits, and change the face of the industry.

2. Compared with other parts forming processes, casting forming has the characteristics of low production cost, large process flexibility, and is almost not restricted by the size of the part and the complexity of the shape and structure. The quality of castings can range from a few grams to hundreds of tons, and the wall thickness can range from 0.3mm to more than 1m. Modern casting technology occupies an important position in modern mass production. Casting occupies 40% to 80% of the total mass in general machines, but its manufacturing cost only accounts for 25% to 30% of the total cost of the machine.

3. In the process of material forming technology development, casting is an extremely long process in history. It has a history of more than 6,000 years in my country. At present, the annual output of castings in my country has exceeded 10 million tons. Due to historical reasons, my country's casting production has been in a relatively backward state for a long time. Compared with the current advanced level of industrialization in the world, the gap in my country's foundry production is not manifested in scale and output, but concentrated in quality and efficiency.
