Understanding ductile iron parts, all of them are experience

With its excellent performance, ductile iron can sometimes replace expensive cast steel and forged steel in use, and ductile iron parts are widely used in the machinery manufacturing industry. Ductile iron parts produced by ductile iron casting technology have the advantages of high strength, high toughness and low price.

Precautions for producing ductile iron parts

Ductile iron is a high-strength cast iron material with comprehensive properties close to those of steel. Ductile iron is obtained by spheroidal graphite through spheroidization and conception treatment, which effectively improves the mechanical properties of cast iron, especially the plasticity and toughness, thus obtaining a strength higher than that of carbon steel.

Classification and characteristics of gears

Spur gear: the two axes of the large gear and pinion are parallel to each other; the direction line of the tooth length is parallel to the wheel axis; in external meshing transmission, the two wheels rotate in the opposite direction; in internal meshing transmission, the two teeth rotate in the same direction; the tooth profile can be made into normal teeth, short teeth and shifted teeth.
