Steel industry requires the provision of highly reliable devices: no defection no failure is allowed. Laminatories and ovens cannot be stopped for the rupture or a malfunctiono of a cylinder. The main characteristics for this applications sector, more than a high afforbability guarantee, is to be high temperatures and dusty proof. In most of the cases temperatures can get over 100°C, for this reason it is mandatory to supply devices whose joints resist and mantain their funcionality even at so high temperatures. Joints and sealing rings made with charbonate florum (VITON) are frequently employed.
The most frequent types of hydraulic cylinders manufactured for the Iron & Steel Industry are:
- Rolling mills
- Presses for hot mould
- Machineries for continuous casting
