Iron Casting

Ductile Iron Castings
Category:Steel casting
Ductile Iron Castings, the strength of its products is very high, very common in life. Common grades are QT400-17 etc.
Product Description
Ductile Iron Castings, its spheroidal graphite can improve the mechanical properties of many cast iron products, and the overall performance is similar to that of steel.It can be used in pressure pipes and fittings, generator parts in the automotive industry, agricultural machinery and construction applications.
Ductile iron is obtained by spheroidization to obtain spheroidal graphite, which can effectively improve the mechanical properties of cast iron, making its comprehensive properties similar to steel, and even stronger than carbon steel. There are many grades of ductile iron, because ductile iron needs to meet the requirements of high temperature or low temperature, corrosion resistance and so on in addition to the common requirements of strength and plasticity.

Depending upon the specifications & drawings

Part characteristic
The surface hardness of ball will be raised further in using the course, and the wear resistance would gather hard, so can raise mill machine production capacity at the same time, and raises cement ratio surface area and reclaim ratio of the extractive mind.

Our cast iron grinding balls can be divided into three categories including the high chromium type, medium chromium type and the low chromium type.

1. The quality index of the high chromium type

The chromium content of the high chromium type product is greater than or equal to 10.0%. And the carbon content is between 1.80% and 3.20%. It is required by the national standard that the hardness of the high chromium type product must be no less than 58hrc, and that the impact value should be greater than or equal to 3.0j/cm. This type of product must go through the hot quenching and the tempering treatment to come up to the hardness.

Currently at home, there are two quenching methods for this type of product including oil quenching and wind quenching. If the tested hardness of this type of product is below 54hrc, then it shows that the quenching treatment is omitted.

2.The quality index of the medium chromium type

The medium chromium type cast iron grinding ball is defined as the chromium content ranging from 3.0% to 7.0%, and the carbon content coming between 1.80% and 3.20%. Its impact value should be no less than 2.0j/cm. . The national standard requires the hardness of this type of product should be greater than or equal to 47hrc. For ensuring the quality, the medium chromium type product should be processed with high temperature tempering to eliminate the casting stress.

If the surface of the steel ball assumes the dark red color, it proves that the steel ball has been processed with high temperature tempering. If the surface of the steel ball still comes with the metal color, then, we can judge that the steel ball doesn’t go through the high temperature tempering treatment.
