is through get spheroidal graphite spheroidization and inoculation, effectively improve the mechanical properties of cast iron, especially improve the plasticity and toughness, and the strength is higher than carbon steel.
Today, the foundry will take you know the annealing heat treatment link of nodular cast iron
1, annealing: get ferritic matrix, improve the plasticity and toughness, eliminating stress and improving the cutting performance.
2, normalizing: pearlite matrix, improving strength and abrasion resistance.
3, conditioning: gain tempered sorbite of the base structure, and good comprehensive mechanical properties, such as main shaft, crankshaft, connecting rod, etc.
4, isothermal quenching, complicated shape and the parts of high comprehensive performance requirements for the bainite matrix organization, as well as high strength, high hardness, high toughness, such as the comprehensive mechanics performance, avoid cracking occurred heat treatment.
