We offer you a full range of possibilities in Open Die Forgings- from 0,5 Tons up to 70 Tons through our unique facilities located in Ostrowiec. The main equipment is described below:
Steel Melting Shop
Equipped with the following:
- Arc Electric Furnace; capacity- 75 Ton, 25 MVA with EBT and a new dust collecting system,
- Ladle furnace with devices for out-of-furnace treatment,
- Vacuum degassing system 0,5 Tor and performance 0,8 ppm H2 (since the beginning of 2009- 0,7 ppm H2), O2 < 25 ppm, sulphur content < 0,005%
- New argon stream covers to prevent from reoxidation and rehydrogenation,
- New vacuum system,
- New devices for state-of-the art computer controlled manipulation and operation of the steel melting process,
- Vacuum refining and bottom pouring or vacuum top pouring processes
We produce ingots of weight from 3 to 125 tons, which then are transferred hot in insulated wagons to the press shop for further treatment.
Our forging equipment includes the following:
- Four hydraulic presses: 2000 T, 3200 T, 5000 T (fully revamped in 2008) and 8000 T
- Forging manipulator for each press
- TR devices for each press enabling forging of continuous grain flow crankshafts
- New, efficient, state-of-the-art-heating furnaces controlled by computer
WE ARE THE ONLY COMPANY IN THE WORLD THAT CAN MANUFACTURE CONTINUOUS GRAIN FLOW CRANKSHAFTS OF ALL SIZES.
