Abstract
A reversible roughing mill for roughing an aluminum or aluminum alloy product, being fed along a feeding plane, the roughing mill comprising: a reversible horizontal roughing stand (1); a first cooling device (10), arranged upstream of said reversible roughing stand (1) configured to cool down, above and below, the product entering the reversible roughing stand (1) by means of a cooling liquid; a second cooling device (15), arranged downstream of said reversible roughing stand (1) configured to cool down, above and below, the product entering the reversible roughing stand (1) by means of said cooling liquid.
Claims15
A reversible roughing mill for roughing an aluminum or aluminum alloy product, arriving at said roughing mill being fed along a first direction according to a feeding plane, the roughing mill comprising:
- at least one reversible horizontal roughing stand;
- a first cooling device arranged upstream of said reversible horizontal roughing stand considering said first direction, and configured to cool down, above and below, by means of a cooling liquid, the product entering the reversible horizontal roughing stand for an odd roughing pass;
- a second cooling device arranged downstream of said reversible horizontal roughing stand considering said first direction, and configured to cool down, above and below, by means of said cooling liquid, the product before further entering the reversible horizontal roughing stand for an even roughing pass;
- characterized in that there are provided:
- at least one temperature sensor arranged both at an inlet and at the outlet of the first cooling device
- at least one further temperature sensor arranged both at an inlet and at an outlet of the second cooling device;
- a first adjustment system for adjusting a flow rate of the cooling liquid in said first cooling device and in said second cooling device on the basis of temperature data detected by said at least one temperature sensor and at least one further temperature sensor, respectively.
A roughing mill according to claim 94, wherein there are provided:
- lateral inlet guides to guide the product entering the roughing mill;
- lateral outlet guides to guide the product exiting the roughing mill;
- and wherein the first cooling device is installed between the lateral inlet guides, while the second cooling device is installed between the lateral outlet guides;
- and wherein channels are provided in a space between lateral edges of the upper manifolds and underlying lateral inlet guides and lateral outlet guides, to protect lateral edges of the product from the jets of the cooling liquid, by diverting an intercepted cooling liquid towards a collection tank.
