The application of ductile iron castings in mines
Ductile iron, with its balance of “strength-toughness-wear resistance” and advantages of low cost and easy forming, has become an ideal material for mining machinery castings. Its application not only solves the pain points of traditional materials (brittle fracture of gray cast iron, high cost of cast steel, insufficient toughness of high-chromium cast iron) but also achieves the goals of “long service life, low maintenance, and high output” for mining equipment through customized composition and process optimization. With the development of mining intellectualization and large-scale (such as large crushers and heavy scraper machines), high-strength and lightweight ductile iron (such as ADI and alloy ductile iron) will play a core role in more severe working conditions.
