The width of the chilled iron should be at least 10% of the chill size.

Resurrecting chill wedges for ductile iron production: often forgotten as a means to measure ductile iron nucleation potential, foundries can turn to chill wedges as a simple tool to ensure melt quality

Chilled iron abrasive held in a four-tonne silo with twin outlets is used to provide a high-quality surface that is regular, clean and rust-free in order to optimise the long-term performance of the final paint finish.

Manufacturer upgrades quality

However, chilled iron was brittle and it was difficult to keep the castings from warping during the chilling process.

Plowmaker to the world: experience in the furrow paid off for James Oliver

The blastroom was introduced primarily for the blast cleaning with chilled iron grit (G24) of turbine casings, which can measure up to 1.82 metres (10ft) in diameter, and other large turbine components, but it also features an integral chamber, which was specially designed to house metal spraying equipment.

Space saving blast cleaning

Regardless of the type of abrasive used, whether chilled iron, malleable iron or steel, abrasive consumption increases as the size of particle removed by the separator increases.

The principles of centrifugal blastcleaning

A wide variety of different abrasives can be used to suit the material involved and the effect required, including aluminium oxide, chilled iron, stainless steel shot and glass beads.

Automatic blast cleaning

If wear-resistant chilled iron microstructure is desirable, like in automotive camshaft applications, FPM in the surfaces of eccentrics won't be lined, and solidified iron is exposed directly to the permanent mold.

Another approach to iron casting: the permanent mold process

The efficiency of the recovery system has enabled Cementation to use relatively expensive chilled iron abrasive and still make big savings in abrasive costs compared with the company's previous procedures.

Containerised blast room increases efficiency. (Installations)

For example, it didn't take long for chilled iron car wheels, cast iron engine blocks and heads, soil pipe, and ingot mold markets to deteriorate.

Coping with changing markets

The chilled iron abrasive used quickly cleans the equipment to bare metal and can be recycled many times.

Blast room speeds bogie cleaning. (Installations)

The area from the apex of the wedge to the end of the white area is designated as "clear chill." From the end of the clear chill to the area where the last spot of white iron is visible is called the "mottled zone." The "total chill" is measured from the junction of the gray fracture to the first indication of chilled iron.
