The working process of the emulsion lifting baffle mechanism of the six-roller single-frame reversible cold rolling mill is as follows:
as shown in FIG. 3, the emulsion lifting baffle mechanism of the six-roller single-frame reversible cold rolling mill is arranged at the inlet and outlet of the mill.
The plate belt is in a tension-free state when the pass is in threading or final pass ending, the lifting hydraulic cylinder 9 extends to the maximum stroke, the lifting baffle plate 1 is completely lifted, the belt can smoothly pass through, and scratch is avoided.
During rolling, as shown in fig. 3, all emulsion nozzles 12 on the inlet side of the rolling mill spray a large amount of emulsion, and the emulsion nozzles 12 spray the emulsion inwards although the speed of the steel strip is inwards, a large amount of emulsion still exists on the upper surface of the steel strip 5 on the inlet side of the rolling mill due to the blocking of the rollers, and a certain pressure flows outwards.
On the inlet side of the rolling mill, as shown in fig. 4, the lifting baffle plate 1 falls down, and a parallel flat gap is formed between the end face of the bottom end of the lifting baffle plate 1 and the steel strip 5. According to a gap flow formula between parallel plates:
description: q-emulsion flow out, m 3 ·s -1
Delta p-difference in emulsion pressure inside and outside the baffle, pa
Delta-gap amount, m; delta < < L, delta < < B
Mu-emulsion dynamic viscosity, pa.s
U-strip speed, m.s -1
L-width of lower end face of baffle, m
B width of strip steel, m
As can be seen from the above formula: the gap amount is reduced, the speed of the steel belt 5 is increased, the emulsion pressure in the lifting baffle plate 1 is reduced, and the outflow flow of emulsion is reduced. According to theory and field experience, the proper gap amount is adjusted through the positioning screw 8, different emulsion injection flow rates are set according to different speeds of the steel belt 5, so that the emulsion pressure in the lifting baffle plate 1 is adjusted, and the reverse injection action of the upper plate surface emulsion injection beam 2 can effectively reduce the emulsion pressure in the lifting baffle plate 1, so that the emulsion outflow flow rate is smaller than 0, and the backflow of the emulsion at the inlet is prevented.
During rolling, as shown in fig. 3, the emulsion nozzle at the outlet side of the rolling mill does not spray emulsion, and the upper and lower surfaces of the steel strip 5 are only slightly splashed emulsion residues due to the isolation of the splashed plates by the blocking of the rollers.
The outlet side of the rolling mill is as shown in fig. 5, the lifting baffle plate 1 at the outlet is lifted by 50mm to stop, so that effective purging space and distance are ensured, the purging nozzles 15 of the upper plate surface purging beam 4 and the lower plate surface purging beam 7 at the outlet are opened, the flat type large-blowing nozzle can form an upper air wall and a lower air wall, residual emulsion on the clean plate surface is blown dry, and the effect that the outlet eliminates emulsion residue on the strip surface is realized.
