Description
Technical field
The present invention relates to casting technology fields, more particularly to a kind of wear-resisting low temperature resistant spheroidal graphite cast-iron.
Background technique
Spheroidal graphite cast-iron is that a kind of spherical cast iron is presented in the stone mill in cast iron, forms stone mill by spheroidising spherical,
This globular graphite can make stress collection medium and small, and matrix is isolated in reduction.It is tired since the intensity of spheroidal graphite cast-iron, modeling degree, toughness are high
For labor intensity close to medium carbon steel, wearability is better than non-alloyed steel, and cutting ability can compare favourably with gray cast iron, and it is excellent that manufacturing cost is low etc.
Point has been widely used in fields such as mechanical and automobiles.With the development of modern industry, to spheroidal graphite cast-iron, especially have
Have specific characteristics energy, such as has wear-resisting low temperature resistant spheroidal graphite cast-iron, and demand is increasing.
Summary of the invention
