Valve body sand casting technology analysis
First, the valve body sand casting process
Valve body sand casting is a common casting technology, has a wide range of applications in industrial manufacturing. The process mainly includes the following steps:
1. Design mold. Designed to meet the size of the valve body sand mold, to ensure the accuracy and quality of casting.
2. Production of sand mold. According to the design of the mold, the sand mold material to produce a sand mold, leaving the shape of the valve body space inside the sand mold.
3. Pouring molten iron. Reserve the outlet in the sand mold, pour the molten iron into the sand mold to fill the space of the valve body, and wait for the molten iron to cool and solidify.
4. Break the mold and take it out. To be completely cooled molten iron, the sand mold broken, remove the casting of the valve body.
Second, the advantages and disadvantages of the valve body sand casting technology
Valve body sand casting technology has the following advantages:
1. Low production costs. Compared with other casting technology, sand casting production costs are lower, can be more economical to achieve mass production.
2. Flexible design. According to different production requirements, can be flexibly designed in different shapes and sizes of sand, to meet the diverse production needs.
3. High casting efficiency. Sand casting technology has high production efficiency and can realize mass production.
But the valve body sand casting technology also has the following shortcomings:
1. Low casting accuracy. Sand casting technology casting accuracy is relatively low, unlike precision casting technology, the need for additional processing and adjustment of the cast product.
2. Limited surface quality. Because the surface quality of sand casting is limited by the sand material and mold, so the surface quality of the valve body castings may not be able to meet the fine requirements.
Third, the valve body sand casting technology and the scope of application of problems
Valve body sand casting technology is suitable for mass production and the size of the casting is not high demand, such as steel, alloy castings. However, the technology also has some problems in the production process, such as:
1. The reuse rate of sand material is low, which is not conducive to environmental protection.
2. Poor surface quality of sand casting may lead to substandard appearance and internal quality of castings.
In summary, the valve body sand casting technology is a casting technology with advantages and disadvantages, and its scope of application and problems also need to be gradually solved in the actual production.
