Non-fracture Express Method of Quality Control of Cast Iron Castings

Description

On the base of research of remaining magnetization of gray, high strong and alloyed cast irons and determinations of functional relationships between the correlation structured constituents, hardness and beside features of quality of casting the samples of small-dimensioned ferrous-probe instruments are created for control of hardness and qualities of castings.


Dependency of remaining induction from general
value of carbides Fe3C in cast iron


Dependency of velocity of sound in cast iron
from percentage contents of globular graphite
under different degrees of eutectics.

As a result of research of acoustic features of gray and high strong cast iron in pour and thermal treated states, the universal analyzer of spectrum of sounding of the castings and several samples of portable small-dimensioned instruments for non-destroy optimality checking operations of modifying cast iron are created.

Ferrous-probe Instrument for non destroy checking hardness of cast.
Fluxgate device for nondestructive
