Problems solved by technology

It is practically impossible to use a gate to intercept the pickling acid, since in this case, among other things, the liquid level will often be higher than the labyrinth seal between the pickling tank and the end chamber

Embodiment Construction

[0015] figure 1 A pickling tank 1 is shown, the bottom 2 of which is supported on a tray 4 with pillars 3 without seams. The steel strip 5 moves in the direction A in the processing liquid 6 with a liquid level of 7. At the end of the treatment tank 1 is provided an outlet tank 8 into which the liquid flows and is discharged through a laterally arranged discharge pipe 9. In order to better adjust the liquid level 7, a protective belt 10 that can best be drawn out is provided. The protective belt 10 is designed such that the steel belt 5 is slightly higher than the wall 11 of the outlet groove 8 when exposed from the liquid. Due to the expansion, the opposite wall 12 can move in the direction of arrow D within the disk 4.

[0016] The groove 13 for accommodating the press rolls 14, 14' is arranged separately from the groove 1. The top of this trough can be closed. At the other end of the treatment tank 1 is provided a tank 13 of the same type with press rolls 14, 14'. The connect...

Abstract

A continuous steel strip treatment unit, having squeeze rolls (14, 14') located in separate containers (13) at treatment vessel ends, is new.

Description

Technical field [0001] The invention relates to a continuous processing system for steel strips, in particular to a continuous processing system using a processing tank for pickling. Background technique [0002] Such a system is known from US 5,566,694, for example. Among them, a pickling tank is suspended between two end chambers with press rolls. If the tank is made of synthetic material, it will sag due to the huge weight of the dipping acid and the temperature involved. If the end chamber is also made of synthetic material, deformation will occur around the suspension, and problems will occur, especially sealing. It is practically impossible to use a gate to intercept the dipping acid, because in this case, needless to say, the liquid level is often higher than the labyrinth seal between the pickling tank and the end chamber. Summary of the invention [0003] Therefore, the object of the present invention is to create a steel strip processing system where the liquid level i...
