Patent ID: 7424946

Claim:
A roller cleaning process for a roller oven comprising a series of rollers ( 21 ) of which a group of rollers ( 22 ) is connected to a flat bloom ( 40 ) or similar steel structure, the rotation of each roller ( 21 ) can be activated independently of the remaining rollers of the series of rollers ( 21 ) by means of activation devices, characterized in that said roller cleaning process comprises the following phases: a) activating the rotation of at least one roller ( 34 ) of the at least one group of rollers ( 22 ) with a module and/or direction rate which is such as to cause the scraping of at least one roller ( 34 ) against the flat bloom ( 40 ) so as to remove the flakes of oxide from the at least one roller ( 34 ) wherein phase a) comprises the following phases: activating the rotation of at least one roller of the head group of rollers ( 32 ) with a rotation direction which opposes the advancing of the flat bloom ( 40 ) towards a rolling mill ( 60 ); activating the rotation of the remaining rollers of the group of rollers ( 22 ) in contact with the flat bloom ( 40 ) with a rotation rate which is such as to cause the advancing of the flat bloom ( 40 ) in the direction (F) with a lower module rate than that of the at least one roller ( 34 ).
