As shown, the rolled material produced in the form of slabs, beam blanks, billets (Billet), etc. in the performance equipment is transferred to the rolling mill and reheated in the heating furnace (1), then the rough mill (2) and the intermediate rolling mill Rolling is finished while passing through 3 and finishing mill 4, and it cools through the cooling system which consists of the cooling stand 5 and the cooling bed 6.

The rolled finished rolled product is cut for dividing into a suitable length in accordance with the length of the cooling phase 6 in the cutter (not shown) or to remove defective parts occurring at the leading and trailing edges in the manufacturing process of the rolled material. The process of cutting the front end and the rear end is performed.

Rolled products, such as the section steel, which has passed through the cooling bed 6, are re-cut to a predetermined length in the cutting machine 7, while being calibrated, transported and aligned through the calibrator 8, and then bundled into a bending device 9 to be finished. It goes through the process of being shipped.

Rolled material thermal insulation device 100 of the present invention is installed at the front position of the heating furnace (1), by reheating in the heating furnace (1) by storing and keeping the rolled material manufactured in the performance equipment and transferred to the rolling mill The cost is reduced.
