Description
Technical field
The utility model belongs to metal rolled technical field, relates to the accessory device on a kind of straightening descaling mill be used in coupled pickling and tandem mill or continuous acid-washing unit before hot-strip pickling, specifically a kind of straightening descaling mill self adaptation working roll box.
Background technology
In coupled pickling and tandem mill or continuous acid-washing unit, in order to improve the pickling efficiency of hot-strip, before pickling, usually will carry out scale breading to Surfaces of Hot Rolled Strip, and straightening descaling mill is the key equipment abolishing belt steel surface iron scale.Iron scale due to belt steel surface is fragile material, and base material is elastic-plastic material, when band steel is by straightening descaling mill, the band steel contacting side with straightening descaling mill working roll is compressed distortion, make the iron scale on its surface broken, and opposite side is subject to stretcher strain, the iron scale on its surface is cracked.Hot-strip, through the stretch bending repeatedly on each working roll, makes the iron scale on its surface loose and partial exfoliation.Straightening descaling mill is generally two curved one versions rectified, i.e. two groups of bending units and one group of resistance straightening unit.Often organize bending unit to comprise 2 covers and bend working roll box, namely upper and lower bending working roll roller box is each a set of, and the working roll box of resistance straightening unit only has a set of, no matter is the working roll box of bending unit or the working roll box of resistance straightening unit, is all referred to as working roll box.
Aborning, hot-strip can contact with working roll by during straightening descaling mill, because working roll is driven voller, can produce friction between, cause work roll surface to wear and tear.If in the good situation of incoming profile, work roll surface meeting uniform wear, but in most of the cases, hot rolling raw material plate shape is all undesirable, there is various shape wave, add that existing straightening descaling mill working roll roller box self rigidity is all relatively good, when causing band steel by straightening descaling mill working roll, the usual skewness of band steel pressure that work roll surface is subject to, like this after working roll work a period of time, partial rollers surface wear near two ends is comparatively serious, namely eel-like figure shape region is all formed at the two ends of working roll, in the middle of this shape, little two ends are large, and the existence of camber also can increase the weight of the wearing and tearing of working roll.When the band steel produced narrows from the width, the working roll of this heavy wear still can use, once production width specifications is greater than the band steel of working roll even roller face length degree, due to band steel by eel-like figure shape region on working roll time, the iron scale of this region belt steel surface can not effectively be abolished owing to being out of shape uneven, the working roll that now just must more renew, otherwise the follow-up pickling effect of hot-strip and rolling quality can be had a strong impact on, and then affect end product quality.Thus, existing roller box version can cause the working roll life-span not long, and roll change frequency strengthens, and have impact on the normal operation of unit to a certain extent, adds production run cost.
Therefore, be necessary very much the working roll box structure exploring a kind of brand-new straightening descaling mill, working roll is made to have certain stressed ability adapting to supplied materials template, automatically adjustment and Surfaces of Hot Rolled Strip, make work roll surface uniform wear as far as possible, thus improve the working roll life-span, reduce roll change frequency, and then reduce the production run cost of unit.
