EBROACERO, S.A.

TECHNICAL OFFICE
This section is at our customers disposal so we can help in the design of the castings. A proper design favours obtaining the quality level required in the specifications.

When a customer entrusts us with the manufacturing of a part, our widely experienced engineers carry out the dimensional, feeder and riser location calculations. They study the best model concept, draw up the plans for their manufacture and define the most suitable moulding process for the kind of part under consideration, indicating important aspects to be kept in mind such as melting speed and temperature, areas of the mould to be protected, etc.

TECHNOLOGY
Providing simulations supports us for choosing the most convenient alternative.

Thanks to a technological support agreement with one of the most important European material research centres, we have highly qualified external consultants at our disposal.

MOULDING
 This section has the necessary facilities for preparing sand and resin mixtures used for the manufacture of mouldings and cores. Silica, chromite, zirconium, olivine and other sands are agglomerated with phenol-alkaline and furanic-based resins and catalysts of different origins.

MELTING
Ebroacero S.A. has two basic process magneto-hydraulic regulation electric arc furnaces with inert gas injection from the bottom which allow for the melting of parts of up to, approximately, fourteen tonnes of net weight. Different material qualities are manufactured with these means, such as:

• Carbon steels
• Low alloyed steels
• Martensitic and Austenitic Stainless Steels
• Refractory steels
• Wear resistant manganese steels
• Laminar graphite iron
• Nodular graphite iron
• Wear and abrasion resistant alloyed white iron
• Ni-resist heat and corrosive agent resistant iron

HEAT TREATMENTS
We have the necessary facilities to carry out the heat treatments required by the different kinds of steel. These treatments are:

• Annealing
• Normalising
• Air or water quenching
• Tempering
• Stress relieving

For these tasks there are four furnaces with the following dimensions:

· Mobile rectangular base furnace capable of reaching temperatures of up to 1200ºC with a maximum load of 20 tonnes and measuring 4000 x 3500 x 1970 mm.

· Mobile rectangular base furnace capable of reaching temperatures of up to 1000ºC, with a maximum load of 30 tonnes and measuring 6500 x 3500 x 1700 mm.

· Rectangular furnace capable of reaching temperatures of up to 1200ºC with a maximum load of 3.5 tonnes and measuring 5000 x 1500 x 1700 mm.

· Circular pit furnace capable of reaching temperatures of up to 1000ºC with a maximum load of 30 tonnes and measuring 6000 mm. diameter x 2500 mm. high.

MACHINING
Ebroacero S.A. is aware of customer needs for receiving, either in their facilities or their assembly sites, their parts completely machined. For this reason we have acquired the necessary machines with enough capacity to machine all the parts we manufacture. The maximum capacities of the machine tools at our disposal are the following:

· VERTICAL CNC TURNING MACHINES for parts of a maximum diameter of 8500 mm x 2600 mm. height.

· CNC MILLING MACHINE:

       - X=18000mm

       - Y=4000mm

       - Z=800mm

· PROGRAMMABLE GEAR HOBBING MACHINE for gears of a maximum diameter of up to 7060 mm. module 50 and height of 2200 mm.
