The specific embodiment

Like Fig. 1, Fig. 2, shown in Figure 3,

A kind of rolling stainless steel band system, uncoiler and winder before and after comprising, uncoiler and winder are the retractable equipments of steel band, are the equipment of using always.It is by motor-driven that first pinch roll, 2, the first pinch rolls are installed in the back of uncoiler 1, comprises up-down rollers, clamp steel band and be fed forward, and be power set.First pinch roll 2 is transported to second pinch roll 3 with steel band; And first plate shearing machine 4 and welding machine 5 be installed between two pinch rolls; The effect of plate shearing machine is the underproof steel band part that prunes away; Especially the first-class position of steel band, welding machine is that the steel band in the different steel coil strip is welded, to realize continuous production.Second pinch roll 2 back is through being transported to the 3rd pinch roll 7 with steel band behind the S tightening roller 6, two rollers about a S tightening roller 6 wherein comprises, and steel band twines the tensioner dynamics that is used to regulate steel band from the horizontal S shape of top formation.Then steel band is transported to first alkaline bath 8 and first rinse bath 9, steel band is carried out preliminary surface treatment, apply through the 4th pinch roll 10 and be sent to first drying baker 11 behind the transmitting power and dry.Then be not right after the person the back be the first tensioner buffer unit.

The first tensioner buffer unit has identical construction, comprises S tightening roller 12 ', turns to correction roller 12 and kink dolly 13, and some groups of slewing rollers 13 ' are installed on the kink dolly, reaches the purpose of regulating steel band length through moving of kink dolly.Can guarantee continuous production in process of production, enough cushion spaces are provided.

The steel band that comes out in the first tensioner buffer unit is transported to annealing furnace 17 through first pair of roller correction roller 14, the 2nd S tightening roller 15 and first after surveying the sensor 16 that rises; First surveys the sensor that rises is installed in the tight device of three roll-ins; In annealing furnace, heat-treat, the Technology for Heating Processing of this annealing furnace can be with reference to existing Technology for Heating Processing.First pair of roller correction roller wherein is vertically to arrange, has the effect that turns to concurrently.The 2nd S tightening roller 15 is symmetrically arranged two groups, and the tensioner effect is obvious.

Steel band after the heat treatment successively through the first correction roller 18, three roller tightening rollers 19, second survey the sensor 20 that rises, Three S's tightening roller 21 backs get into sodium sulphate cathodic pickling grooves 22; Carry out surface treatment; Getting into nitric acid cathodic pickling grooves 25 through first squeeze roll 23, secondary correction roller 24 backs then; And then got into nitration mixture grooves 27 after advancing second squeeze roll 26; Under the driving of the 5th pinch roll 28, get into second alkaline bath 29, second rinse bath 30, second drying baker 31 then again, accomplish the pickling processes on surface.

Survey the sensor 32 that rises in subsequent installation the 3rd; Be used to monitor the tensioning dynamics of steel band; Through being connected to the second tensioner buffer unit behind three roller deviation correcting devices 33, the 4th S tightening roller 34, wherein the second tensioner buffer unit and the first tensioner buffer unit have identical mechanism and function again.The 4th S tightening roller 34 is symmetrical set two groups.

Last steel band is connected on the take-up machine 40 after through second pair of roller correction roller 35, the 5th S tightening roller 36, the 6th pinch roll 37, second plate shearing machine 38 and the 7th pinch roll 39, accomplishes whole technological process.The 5th S tightening roller 36 wherein is symmetrically arranged two groups.

In above-mentioned uncoiler, have two pay-off roll, have two wind-up rolls in the winder.Such one opens one is equipped with, and can realize continuous production.

Embodiment recited above describes preferred implementation of the present invention; Be not that scope of the present invention is limited; Design under the prerequisite of spirit not breaking away from the present invention; This area person skilled all should expand as in the determined protection domain of claims of the present invention various distortion of the present invention and improvement.
