Our company
S. Agostino S.p.A is a
private company leader in the field of rolls and rings
for the steel and non-ferrous industries since 1956.
The experience we have
gained assure the most efficient and top quality rolls
for rolling mills.
Our manufacturing range
is the following:
• rolls for reinforced
concrete round and wire rod mills (open and continuous
design)
• rolls for section and
bar mills (open and continuous design)
• rolls for billet,
medium-size and large section mills
• rolls for flats in the
line stands and continuous mills
• rollers for
straighteners, pinch-rolls and rolls mills for piping
• rolls for calanders
and mixing mills (rubber, resin, plastic, PVC, paint,
soap, paper)
• rolls for working
cereals and alimentary
• shells for brick-kiln
machines
• pistons
Our production includes
rolls and rings in hypereutectoid steel, indefinite and
clear chill cast iron, nodular pearlitic and acicular
cast iron.
The sales network is
expanding on the national and international market
thanks to the competitivity of our product. In Italy and
abroad we supply all steel producers and constructors of
rolling mills, for steel, rubber, plastic and
brick-kiln-machines, we export above all to Europe . the
Far Est. the USA , Canada and South America .
Our Service Department,
available before and after sales, assures all the
technical support which is necessary for the selection
and optimum utilization of rolls. It also focuses on the
analysis and development of research topics intended to
meet the growing and innovative requirements of rolling
mills.
The Quality Certification
obtained in 1994 (UNI EN ISO 9001:2000) and the
experience acquired over the years, guarantee the
absolute qualitative constancy of the product.
FOUNDRY
Our Foundry was the first
in Italy to install electric induction furnaces designed
to produce rolls. In particular, it has 3 electric
induction melting furnaces for liquid preparation of 6
and 15 tons and gas furnaces for heat treatments: all
furnaces are automatically controlled by PLC.
Only top quality raw
materials are used to charge melting furnaces.
We also make use of
mechanized plants for the preparation of sands and of
automatic machines for flask moulding. The productive
capacity amounts to 8.000 tons a year.
MACHINE SHOP
The
machining is made in 2 different roll shops; one is
directly connected to the Foundry by roller conveyors
for transferring rough castings to Machining Department.
We have numerical control lathes, boring and grinding
machines as well as knurling machines for rebar and
perforating machines for central and peripherical holes
which can supply the Customers with rolls ready for use.
The productive capacity
amounts to 5000 tons a year and is based on equipment
which can produce rolls with a maximum diameter of 1200
mm .
Non destructive tests are
carried out on each type of roll during the production
cycle.
CHEMICAL
METALLOGRAPHIC LABORATORY
The lab has a
spectrometer which can carry out chemical analysis in
real time on the specimens taken during the preparation
of the liquid in melting furnaces as well as on the
samples taken from rolls for production control.
The spectrophotometer is
used for special analysis and for characterization of
ferroalloys; moulding sands are controlled by adequate
devices.
Metallographic tests are
carried out on produced materials by means of an optical
microscope which can verify the conformity of
structures.
INSPECTION AND
SHIPPING
Completely finished machined rolls included central and
peripherical holes, crossing and convex grinding are
transferred by roller conveyors from the Machine Shop to
the Inspection and Shipping Department.
The final inspection
includes: dimensional controls, hardness, ultrasonic
test, roughness, and any other control required by the
Customer.
The roll number assigned
at the beginning of the production cycle is now stamped
on the roll so as to identify the product speedly and
correctly.
Painting and packing
represent the final steps of the production cycle which
is completed by shipping.
