Abstract

The invention discloses a rolling system for a medium and thick steel plate in a thin gauge. The rolling system comprises a heating furnace, a descaling box, a roughing mill, an intermediate blank cooling device, a finishing mill, a thickness tester and a conveying roller way; the rolling system is characterized in that the roughing mill is connected with a roughing mill control system; the finishing mill is connected with a finishing mill control system; the thickness tester is connected with a controller; and the controller is connected with an alarm. The rolling system provided by the invention solves the problems that the temperature drop is fast, the temperature difference between the head and the tail of a steel plate is large, and the plate shape is hard to control when the thick gauge steel plate is rolled, and thus, the rolling system creates good conditions for straightening the steel plates.

Description

technical field [0001] The invention relates to the technical field of medium-thick plate rolling technology, in particular to a thin-gauge medium-thick steel rolling system. Background technique [0002] At present, the market situation is becoming more and more serious, the production capacity of medium and heavy plates is seriously overcapacitated, and the downstream demand is weak. The price of conventional specifications of medium and heavy plates has been hovering at a very low level, and it is difficult to achieve profitability. However, the price of thin-size products is slightly higher, and there is a certain degree of profitability. For the medium and heavy plate production line, only by working hard on thin gauges and creating our own competitive products can we better keep up with the market, seize opportunities and win customers. [0003] However, the most difficult part in the production of thin-gauge steel plates is the finishing mill process. During the ...
