Description

The anti-collapse device of coil of strip
Technical field
The utility model relates to the servicing unit in the coil of strip cold-rolled process, more particularly, relates to the anti-collapse device of a kind of coil of strip, and this anti-collapse device can prevent the coil of strip volume that collapses.
Background technology
Behind the process secondary cold-rolling, because the very thin thickness of band steel, and after high temperature recrystallization annealing, the existence of MgO powder and the effect of MgO powder scaling loss between the layer of coil of strip and the layer, can cause the support force of coil of strip self not enough, the integral body that is easy to generate coil of strip collapse the volume phenomenon (promptly coil of strip axially on collapse into ellipse), cause road, back unit can't go up volume.At present, existing both at home and abroad cold rolling unit is general to be adopted and steel bushing is set prevents the coil of strip volume that collapses, see also shown in Figure 1, coil of strip 1 is twisted on the steel bushing 2, after coil stripping car unloads volume, coil of strip 1 just can connect coil of strip 1 and steel bushing 2 and send into together in the high temperature recrystallization annealing unit furnace and anneal after tilting gear is translated into upright volume.Though adopt steel bushing 2 can keep coil of strip 1 shape, prevent coil of strip 1 volume that collapses, but because steel bushing 2 will enter in the high temperature recrystallization annealing unit furnace together with coil of strip 1, under such worst hot case, steel bushing 2 must use expensive high temperature resistant stainless steel material, and it is very big to produce needed circulation spare part quantity, has increased production cost greatly.Simultaneously, burning down up to 1200 ℃ of high-temperature bakings for a long time of high temperature recrystallization annealing unit, because steel bushing 2 outer surfaces can not be coated with the MgO powder, therefore coil of strip 1 inner ring and the steel bushing outer surface is easy to generate extra band steel high temperature adhesion and the Internal and external cycle of coil of strip 1 heats unequal problem, thereby influenced the quality of coil of strip 1, caused the certain economic loss.
Therefore, need that a kind of new anti-collapse device of coil of strip overcomes that steel bushing cost of the prior art is higher, in the high temperature recrystallization annealing process easily with coil of strip adhesion and the shortcoming that causes coil of strip Internal and external cycle heating inequality.
