Problems solved by technology

[0044] [44] However, every once in a while, customer needs evolve and periodically require changes to the plant's production plans, and changes in steel composition and the dimensions of the strip produced are also quite frequent
Accommodating the passage of a single short coil is possible, as opposed to the lack of packing that is exacerbated if several short coils are to be processed sequentially

Embodiment Construction

[0078] [78] As noted above, figure 1 The graph in represents the time taken for the different steps A to I in the overall connection process carried out in the usual way in the input section of the continuous in-line processing unit.

[0079] [79] figure 2 Schematically represents the structure of the input section in the advanced plant according to the first embodiment of the present invention.

[0080] [80] As usual, the strip to be processed can be unwound from either of the two uncoilers 11, 11', both of which are connected to the device 12 for unwinding and straightening the strip. , 12' are connected, and are connected with the cutting head machine 13, 13'. A switching device 14 is able to insert the strip M or M' from the unwinder 11, 11' respectively into the input section.

[0081] [81] According to the invention, the inlet section 1 is divided into two parts 3, 4, between which an intermediate accumulator 5 is arranged. As usual, after exiting the input section,...

Abstract

The invention relates to a novel method for managing the entry of a new reel (11') in a continuous in-line installation for processing a strip-shaped product, in particular, for passing though the line of short reels. According to the invention, the overall time for carrying out the general method of connecting a new reel (11') is divided into at least two periods (T1, T3) realized in at least two successive portions (3, 4) of the entry section (1) of the installation, and the connection cycle is split into two separate phases (S1, S2) between which a variable length of strip is kept in at least one intermediate accumulator (5) in order to provide a time interval (T2) of a variable duration between these periods of the connecting method. The invention is used, in particular, in continuous steel strip pickling lines.

Description

technical field [0001] [01] The present invention relates to a method for controlling the supply of new coils to a continuous in-line processing unit for processing strip-type products, the invention also relates to An improved plant for carrying out the method is included. Background technique [0002] [02] It is known that the manufacturing process of steel products, especially steel strips, requires the completion of a series of sequential processing steps. Generally, after the preparation of the steel stock is completed and the steel stock is cast in a mold, or after the continuous casting is completed, the steel product is hot-rolled, wound into a coil, and then subjected to Various operations, generally speaking, annealing and descaling corrosion, of which hot rolling can be carried out either on reversing rolling mills or on tandem rolling mills. The strip thus rolled can then be subjected to various treatments such as degreasing, annealing, etching, surface coating...
