Description
Technical field
The utility model relates to steel rolling roll mill field, particularly relates to a kind of roll mill guard plate apparatus.
Background technology
Roughing roll mill is requisite equipment during hot-strip is produced, the rotation direct influence zone product made from steel quality of roughing roll mill.And the fixing and equipment gap of breast roll backplate directly affects belt steel surface, breast roll is caused to wear and tear uneven, influence of rolled stability, the as easy as rolling off a log steel-fastening accident that causes; Breast roll backplate weares and teares very fast under the impact of milling train high pressure descaling water simultaneously, and service life is only 6 months, and spare part is very expensive, and it is very large to change breast roll backplate task difficulty.
Breast roll backplate plate face of the prior art is little, lightweight, only has a support to be fixed in breast roll bearing housing holddown groove.Because milling train top and bottom rolls rotating speed when nipping steel billet is undesirable and then cause steel billet head to produce discount phenomenon, under the high roll-force effect of milling train, easily make breast roll backplate produce distortion, breast roll backplate and breast roll is caused not to have effective clearance, there is friction phenomenon, or by breast roll locking, the equipment accident such as cannot to rotate, affect high-strength working and batch production, and easily other equipment are damaged, reduce output.
Summary of the invention
The purpose of this utility model is to provide a kind of roll mill guard plate apparatus, is integral design, increases the anti-wear performance of equipment, extension device service life, reduce equipment failure rate, reduce equipment breakdown, ensure belt steel product quality, improve the security of equipment simultaneously, reduce operation intensity, ensure equipment use effect, extension device life cycle, avoid the generation of great quality accident, strengthen lumber recovery.
For achieving the above object, the utility model realizes by the following technical solutions:
A kind of roll mill guard plate apparatus, comprise breast roll backplate, backplate front support, backplate rear support, reinforcement, backplate Backside support, base, described backplate Backside support is fixed on the two ends of backplate rear support, at the bottom firm banking of backplate Backside support and backplate rear support, between front support and rear support, be fixed with reinforcement, breast roll backplate is fixed on the upper end of backplate front support, backplate rear support and reinforcement.
Described base is processed with locating hole.
Described breast roll backplate upper surface is processed with wearable overlay.
Compared with prior art, the beneficial effects of the utility model are:
A kind of roll mill guard plate apparatus is integral design, increases wearable overlay at backplate upper surface, effectively slow down equipment attrition, extension device service life, reduce equipment failure rate, reduce equipment breakdown, ensure belt steel product quality, improve the security of equipment simultaneously, reduce operation intensity, ensure equipment use effect, extension device life cycle, avoids the generation of great quality accident, strengthens lumber recovery.

Detailed description of the invention
Below in conjunction with Figure of description, the utility model is described in detail, but it should be noted that enforcement of the present utility model is not limited to following embodiment.
As Figure 1-3, a kind of roll mill guard plate apparatus, comprise breast roll backplate 1, backplate front support 2, backplate rear support 4, reinforcement 3, backplate Backside support 5, base 6, described backplate Backside support 5 is fixed on the two ends of backplate rear support 4, at the bottom firm banking 6 of backplate Backside support 5 with backplate rear support 4, between front support 2 and rear support 4, be fixed with reinforcement 3, breast roll backplate 1 is fixed on the upper end of backplate front support 2, backplate rear support 4 and reinforcement 3.
Described base 6 is processed with locating hole 7.
Described breast roll backplate 1 upper surface is processed with wearable overlay.Steel billet can be reduced to the wearing and tearing of backplate and water under high pressure to the erosion corrosion of backplate.
See Fig. 1, a kind of roll mill guard plate apparatus is arranged between working roll 8 and breast roll 9, and in the embedded slot being fixed on breast roll bearing housing of backplate front support 2, backplate rear support base 6 is bolted on the foundation base of working roll roller-way.See Fig. 3, the locating hole 7 on base 6 is bolt connecting holes of backplate rear support base 6 and working roll roller-way foundation base.
Backplate rear support 4, backplate Backside support 5 are overall structure from top to bottom.See Fig. 2, be provided with the pilot hole 10 of assembling bolt during erection unit on the top of locating hole 7.
Former and later two support the stability increasing breast roll backplate 1, simultaneously for increase backplate surface area and guard plate thickness provide stable basic condition.
Breast roll backplate 1 is by the machined steel plate thick for 80mm of 20# cast steel; there is extremely strong impact resistance, better stabilizing power during steel billet head discount can be ensured simultaneously, play proterctive equipment effect by backplate guide effect; reduce equipment breakdown, improve output.
A kind of roll mill guard plate apparatus of the utility model, can effectively prevent because band steel discount seriously causes breast roll backplate to be out of shape, serious wear, is even taken out of milling train by the steel billet that discount is serious, stay billet surface and produce equipment breakdown, affect product surface quality; The security of effective raising equipment, ensures that breast roll uses, available protecting breast roll, extends life cycle, reduce spares reserve consumption costs, avoid the generation of great quality accident.
