Hangzhou Yu Chen is Hangzhou Longmen processing center processing , providing mechanical processing services, using a variety of different processing technology. Casting refers to the process of pouring a substance at room temperature into a liquid but solidifying shortly after pouring into a mold of a specific shape to be solidified. Ductile iron processing and gray iron processing technology can not be separated from casting.
    gray iron castings in casting production, casting process design is a necessary link. As the quality requirements of the casting production are increasingly strict, the production rhythm of castings is speeding up, and the process of gray iron processing must be continuously developed.

    gray iron castings are easily exposed to corrosion in the air for a long time. Its quality affects the use and performance of the product. Therefore, corrosion prevention measures should be paid attention to in the process of gray iron processing.

    casting process is used in the processing of gray iron castings, which is also very knowledgeable. The high pouring temperature will cause the sand mold to rise, especially the gray iron with complex sand core, when the pouring temperature is ≥ at 1420 C, the waste products increase and the pouring temperature is 1460 degrees centigrade, the waste product reaches 50%. In the production process, induction furnace melting can control the temperature of molten iron well, and can also provide better processing services.
