Regular overhaul of a winding machine for hot-rolled steel

It will not surprise many that there are no optimal conditions for rotating equipment and other process components in hot rolling mills. First, you have the considerable weight of the steel plates that pass through the mill. Second, high temperatures also exert an influence on the machines that manage the rolling process. That is why the heavy steel industry regularly engages Revimaxx to ensure process continuity.

High temperatures up to 1,270 °C

A hot rolling mill transforms thick slabs of steel into steel sheets with thicknesses of up to 16 mm. Rolling this steel in multiple steps requires heating the plates to a very high temperature between 1,000 to about 1,270 °C. Only then can you make the steel plate thinner and longer using numerous rollers. And eventually - in the final phase - wound into coils. The steel cools down somewhat before coiling, but is far from being at room temperature. And this is certainly the case with the larger 16 mm plate thicknesses.

Undergoing extreme conditions

It is precisely for the final phase that Revimaxx’s overhaul team is regularly called upon. ‘In fact, just about every six months this gigantic machine needs another overhaul,’ said Johan Van Meenen.

’Which shouldn’t be surprising at all given the circumstances. The thickness of the inflexible steel demands a lot from the winding reel in the machine’s C-frame. And on top of that, the material’s high temperature means the system must withstand the most extreme conditions.’

Revimaxx is adept at dismantling machinery on site. And in this particular case, the components for the overhaul job were dismantled from the hot rolling mill.
