Since the 1980s, the development of section steel production equipment has been relatively slow compared to plate and strip mills. Although the rolling mill structure has been greatly improved, such as the development of cantilever CL mill, short stress line high stiffness HS mill, short stress line universal mill, etc., but no completely new type of rebar rolling mill, rolling speed is not much. The new development of section steel production equipment mainly lies in. (1) Continuous casting billet direct thermal loading. (2) Near the end of the shape of the application of continuous casting billet. (3) The development of flexible rolling equipment, has been put into production a variety of flexible rolling capacity of the new steel rolling mill unit, the development of H-beam free size rolling, extension of the road without hole type rolling, multi-roller universal hole type rolling and other flexible rolling technology. (4) The promotion and application of slitting rolling technology, the extensive use of slitting rolls and slitting wheel equipment, with the advantages of increasing production, reducing the number of passes, reducing energy consumption and roll consumption. (5) Tight tolerance precision rolling equipment, the product tolerance range can be controlled in the international standard 1/4 to 1/10, the use of small roll diameter, short roll body and single-hole type mill rolls, high rigidity, compact rolling mill, flat and vertical alternating arrangement of 2 to 3 hole type, small press down, which is the basic characteristics of precision rolling equipment. (6) Low-temperature rolling, temperature-controlled rolling and the application of online heat treatment, comprehensive energy savings of up to 20%, and greatly improve the performance of steel. (7) Modern finishing equipment, finishing equipment to achieve continuous, automated, such as stepper rack cold bed, continuous cut-to-length (CCL) unit, cantilever structure of the single straightening equipment, etc. (8) equipment status diagnosis technology, monitoring equipment operating conditions, timely maintenance.
