Sink Roll

Sink rolls are an simple but difficult roll to build. They work in a very corrosive environment, i.e. molten zinc, galvalume, galvanneal, lead and aluminum... They will typically see temperatures in excess of 800 degrees Fahrenheit for weeks at a time. Materials used are made to withstand this criteria, so they are also difficult to machine. The above roll is made from a 300 or 400 series stainless steel. The body is a centrifugal cast stainless steel and the end bell/journal is from a static casting.

Specifications

Materials:

Typically a stainless steel that could withstand extreme temperatures & high corrosion for extended periods of time.

Body Shape:

There is a variety of different shapes put in the body from straight body, crowned and tapered.

Grooves:

A variety of groove patterns and pitches based on customers specifications.   Special grooves for carbide coatings.

Coatings:

Most automotive product lines have carbide, but some of these rolls have no coatings on them.

Balance:

These rolls can operate at high line speeds, but due to the fact they sit in molten liquid, they typically are static balanced.

Life:

An uncoated roll may last up to 2 weeks, but with carbide coatings and special bushings they have lasted up to 5 weeks.
