Each order for clad is unique, representing the
requirements of a custom-engineered end product. Cladding and backing materials,
thicknesses, and plate dimensions, as well as other special requirements, must be
considered in the manufacturing process.
While actual thickness or combinations of materials may necessitate
the use of alternative plans, the manufacturing of most roll-bonded clad plates is
accomplished by assembling a 4-ply clad "pack", comprised of two "backing
steel" slabs and two "cladding" inserts, as shown in Figure 1. The
thickness and size of these components are specially designed to produce finished plate
with the customer's required parameters.
The assembled pack is then rolled at high temperature and pressure where
the thickness is reduced and the backing steel is metallurgically bonded to the cladding,
as shown in Figure 2.
The parting compound prevents bonding of one cladding insert to the other,
allowing the rolled assembly to be opened, yielding two clad plates, each having the
required cladding and backing thickness, as well as being of sufficient width and length
for the customer's order, as shown in Figure 3.
