Problems solved by technology

[0015] Therefore, on industrial plants according to the prior art, in the case of very wide strips (> 1250 mm), it is not possible to operate at 50%-80% in the duplex region without exceeding the reliable frame load and working load Warm-rolled thin strip made of medium carbon steel or carburized steel and quenched and tempered steel

Abstract

Continuously cast slabs production comprises using device having blooming train (4), roller table (3) for transporting rolled material, roller table section (5) with hoods, unit for leveling pre-strips, inductive device (7) for heating pre-strips to defined temperature, finishing train (10), delivery roller table with devices for cooling hot strip and coiling machines for coiling finished strip. One or more slabs made of carbon steel containing 0.2-0.8% carbon are rolled to pre-strips in the blooming train. The pre-strips are heated to a defined temperature using the combined action of the hood and the heating device, and then rolled. The rolling temperature lying in the upper austenite region in the first deformation stage in the blooming train leads to a conversion of a continuous cast structure to a rolled structure by complete recrystallization. An independent claim is also included for a device for carrying out the process.

Description

Technical field [0001] The present invention relates to a method for manufacturing a high-strength thin flat material that is also very wide and is warm-rolled in a dual-phase zone from thick continuous casting slabs or medium-thick continuous casting slabs or thin slabs on such equipment, that is, the equipment It includes a single-stand or multi-stand roughing mill, a roller table that transports and swings the rolled piece, a roller table section with a reversible heat-insulating cover, a straightening device for straightening the rough rolled piece, and An induction heating device that can controllably heat the rough-rolled product to a specified temperature within the entire length and width of the rough-rolled product, a multi-stand finishing mill, a device with a cooling hot strip and used for coiling and finishing rolling The output roller table of the coiler at the rear of the strip, in which one or more pieces of medium carbon steel or alloy with a carbon content of abou...
