Abstract
A rolling mill has roughing, intermediate and finishing roll stands on a first side of a billet reheating furnace, and a breakdown mill on an opposite second side of the furnace. Billets are heated to an elevated rolling temperature in the furnace and are then ejected to the second side of the furnace for rolling in the breakdown mill before being directed back through the furnace for continued rolling into finished products at the first side of the furnace in the roughing, intermediate and finishing roll stands.
Claims6
A rolling mill comprising:
- a furnace for reheating billets to an elevated rolling temperature;
- roughing, intermediate and finishing roll stands positioned at a first side of said furnace;
- breakdown roll stands positioned at an opposite second side of said furnace;
- means for axially ejecting reheated billets from said furnace to said second side for rolling in said breakdown roll stands into process sections of reduced cross sectional area;
- and
- handling means for directing said process sections back through said furnace to said first side for continued rolling in said roughing, intermediate and finishing roll stands.
A method of rolling billets in a rolling mill, comprising:
- heating the billets to an elevated rolling temperature in a furnace having first and second openings on opposite first and second sides thereof;
- ejecting reheated billets axially from said furnace through said second opening;
- rolling the thus ejected reheated billets into process sections in breakdown roll stands located on the second side of the furnace;
- and
- directing the process sections back through the furnace via said second and first openings for continued rolling in roughing, intermediate and finishing roll stands located on the first side of said furnace.
