Thick plate continuous rolling and continuous plating production line adopting disengagement and engagement method

Abstract

The invention discloses a thick plate continuous rolling and continuous plating production line adopting a disengagement and engagement method. The production line comprises an uncoiling machine, S-shaped rolls, a washing tank, a hot air drying machine, a tensioning machine A, a tensioning machine B, a rolling machine, a tensioning machine C, a tensioning machine D, a bouncing roll, a zinc pot and the like which are sequentially connected. The rolling machine comprises an upper supporting roll, a lower supporting roll, an upper working roll, a lower working roll, an AGC oil cylinder, a thickness measuring instrument, a rear thickness measuring instrument, an inlet tension measuring machine I and an outlet tension measuring machine. The upper working roll and the lower working roll are symmetrically designed. The upper supporting roll is arranged above upper working roll and the lower supporting roll is arranged below the lower working roll. The thickness measuring instrument and the rear thickness measuring instrument are arranged at the two ends of the rolling machine. The AGC oil cylinder is arranged below the lower supporting roll. The tensioning machine A, the tensioning machine B, the tensioning machine C and the tensioning machine D are all provided with disengagement and engagement mechanisms. By the adoption of the production line, the rolling machine and a galvanization production line are combined, the purpose of continuous rolling and continuous plating of the whole production line is achieved through automatic disengagement and engagement of the tensioning machines, the purpose that rerolling is not necessary when hard coils are produced and rolled into base plates is achieved as well, and a reliable guarantee is provided for large-span thin plate production of the production line.

Description

technical field [0001] The invention relates to a closed-loop continuous rolling automatic clutch device for a thick plate continuous production line, which solves the respective required functions of a hot-rolled substrate and an off-line rolled substrate on the continuous production line. Background technique [0002] The raw material of galvanized coils for wide and thick plates is hot rolled steel billets into hot coils. The hot coils are rolled by continuous rolling mills or reversing rolling mills to form hard rolled coils of the target thickness. Hard rolled coils are the raw material substrates for producing galvanized coils. The rolled hard-rolled coils of various specifications are hoisted to the galvanized uncoiler, and galvanized sheets are produced through the following procedures. The production process is as follows: Hang the rolled hard coil with the target thickness on the hydraulic mobile trolley to be fed, send it to the uncoiler through the mobile trolley...

Problems solved by technology

This design not only increases the owner's investment cost several times, because the scheme is still two independent systems, although the electronic control has been optimized, the long-term production cost is very high
