Method for producing steel plates of limit specifications on medium plate production line

Abstract

The invention provides a method for producing steel plates with limit specifications in a medium-thick plate production line. The production limit specification steel billet is set as billet A, and the normal steel billet is set as billet B; after the data information of billet A and billet B is transmitted to the heating furnace, the post personnel In the PDI information screen, select billet B to carry billet A on its back, and the information and objects of billet B will be automatically loaded into the furnace normally. , billet B carries billet A together into the heating furnace for heating; after heating, billet B automatically completes the tapping operation; after billet A is separated from billet B, the data of billet A is manually issued, and then the rolling of billet A and billet B is completed in turn system. The invention can solve the problem that the ultra-thin specification steel plate cannot be rolled due to the limitation of the billet, reduce the production cost of the limit specification steel plate, improve the economic benefit of the enterprise, expand the scope of the contract, and enhance the brand and market competitiveness.

Description

technical field [0001] The invention belongs to the technical field of steel rolling technology, and in particular relates to a method for producing limit specification steel plates with a finished product thickness less than 6.5 mm in a medium and heavy plate production line. Background technique [0002] With the slowdown of market demand, contract specification orders are becoming more and more special. At present, the number of limit specification steel plates with a thickness of 6mm and a finished product width of less than 2m is increasing day by day. For the medium and heavy plate factory, since the width of the finished product is less than 2m, based on the current minimum blank size of 3m that can be loaded in the heating furnace of the medium and heavy plate factory, the minimum length of the rolled steel plate is 56m, which exceeds the production capacity of the on-site cooling bed. The upper limit is 50m. If the billet is designed with panels, the width of the r...
