The brake drum is a security piece, which involves the safety of people's lives and property, and it is also a vulnerable and consumable part. The market demand is particularly large.
The first aspect is mainly to better provide the metallurgical quality of molten iron. The second aspect focuses on finding the right process for the manufacturer.
The failure of the brake drum during use, mainly cracking and wear, but from the customer's complaints and claims reflected in the statistics, mainly the former. That is to say, most of the failed brake drums are cracked and cannot be used in the case of normal wear and even slight wear.
The production process of the brake drum is mainly concentrated in two aspects. First, how to ensure its mechanical properties, the metallographic organization meets the product requirements. But how to reduce its casting defects. Especially in the internal defects of key parts, in reducing the casting defects, I will focus on how to reduce its shrinkage defects, because it is one of the main types of waste and one of the main reasons for failure.
