Furnace rolling mill production line

Abstract

The invention discloses a furnace rolling mill production line. The furnace rolling mill production line is composed of a heating furnace, a slab descaling box, a rough rolling mill, a drum type flying shear, a furnace rolling mill, a continuous rolling mill, a laminar flow cooling device and a coiling machine which are sequentially arranged. The continuous rolling mill comprises a rolling mill body F1, a rolling mill body F2 and a rolling mill body F3. The production line adopts a full hydraulic automatic width control system and a head and tail short stroke control system to control the width and head and tail shape of a rough-rolled intermediate slab. The whole production line adopts a three-level computer for control and management, the first level is a basic automation system, the second level is a process automation system, and the third level is a production quality management system. By the adoption of the furnace rolling mill production line, the whole line material tracking and automatic rolling steel control are realized, and product quality and product competitiveness are improved; width control and head and tail shape control are carried out on the rough-rolled intermediate slab so that the width control precision can be improved; the intermediate strip billet thickness precision control is realized, and the deviation is smaller; and the furnace rolling mill production line can adapt to the production of high-strength varieties and the development of new products.

Description

technical field [0001] The invention relates to the technical field of metallurgical rolling mills, in particular to a production line of a steckel rolling mill. Background technique [0002] Steckel rolling mill has the characteristics of low investment, small footprint and flexible production. It mainly produces special steel and stainless steel. Most of the traditional steel-steel mill production lines rely on one steel-steel rolling mill as a finishing mill to carry out reversible rolling and roll into finished strip steel. At present, the problems existing in the production line of domestic steckel mills are low degree of automation, low quality and precision of strip steel, and relatively low annual output. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the above technical defects and provide a production line for a steckel mill, which has a high degree of automation, a high annual output, and high strip...
