The organization is dependent only on the chemical composition and cooling rate and is assured by the following major technical measures.
Abstract： Under the actual production condition of the traditional technique, it is easy that high chrome white cast iron grinding media forms more internal stress, which is lead to disabled main reason in production and employ condition. The importance of grinding ball cast microstructure is known by analysis hot working whole process, that is, required […]
Automatic casting grinding balls making machine consists of casting line, metal molds online, and pouring line. The casting line includes a sand shooting machine, cooling & heating device, motorized roller table, and casting pick-up device, molds opening device, and vibrating molds cleaning device.
According to GB9441-88, the spheroidizing grade of each furnace number sample and grinding ball is above 1 ~ 2 grade, the size of spheroidal graphite is above 7 ~ 8 grade (100 times Figure 2), the number of graphite balls is more, and the distribution is uniform, the matrix structure (1000x Figure 3) of the […]
After analyzing the elements of grinding ball material for Bainite Ductile Iron Balls, goes to the next step– casting and melting process. Wet sand molding, alloy melting in a one-ton cupola. (1) metal charge: High Quality No. 18 Benxi pig iron, return iron, ferromolybdenum, ferrosilicon, Ferromanganese, scrap steel, return charge, and spheroidized alloy. These metal […]
