Description
Technical field
The utility model relates to a kind of finishing mill outlet structure, belongs to finishing mill equipment technical field.
Background technology
In stainless steel 1580 hot rolling line, the overall material of lower guide and guards of the finishing mill rear end of mm finishing mill unit is cast iron, is positioned between finishing mill outlet and the cold roller-way of layer, plays pilot tape steel and export from finishing mill outlet and be transported to the effect the cold roller-way of layer.In the use procedure of actual production, under this finishing mill outlet there is following defect in guide and guards: on the one hand, because the material exporting lower guide and guards is cast iron, the material hardness of its hardness ratio hot-strip is high, easily cause band steel scratch on the bottom surface, affect the exploitation of product surface quality and high-end product; On the other hand, under existing outlet, guide and guards installation site is fixed, and not easily adjusts; Although further, lower for outlet guide and guard can be adjusted to a little less than outlet roller-way, reach the object avoiding belt steel surface to scratch defect, when rolling Thin Specs (thickness≤2.0mm) product, band steel nose phenomenon frequently occurs, and often causes steel-fastening accident.In view of there is above problem aborning, under being extremely necessary the outlet to finishing mill, guide and guard structure undergoes technological transformation.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of finishing mill outlet transition guide plate, and this transition guide plate both can avoid band steel scratch on the bottom surface problem, can solve again nose problem during ultra-thin gauge rolling.
The technical scheme solved the problems of the technologies described above is:
A kind of finishing mill outlet transition guide plate, it comprises the lower guide and guards of outlet, which increase Wiper blade, Wiper blade is that resin material is dull and stereotyped, under outlet, the upper surface of guide device processes a groove platform near roll side, Wiper blade is arranged in groove platform by set bolt, the upper plane of Wiper blade is higher than the upper surface exporting lower guide and guards, the upper plane of Wiper blade is the rounding off of chamfer bevel with the junction of the lower guide and guards upper surface of outlet, and the nut upper surface of set bolt is lower than the upper surface of Wiper blade.
Above-mentioned finishing mill outlet transition guide plate, described Wiper blade upper surface exceeds the upper surface 5-10mm of the lower guide and guards of outlet, and Wiper blade has the chamfering of inclination respectively with the upper and lower of the groove platform link of the lower guide and guards of outlet.
Above-mentioned finishing mill outlet transition guide plate, the bottom surface of described groove platform has multiple screw, screw is uniform in groove platform, Wiper blade there is the fixing hole that the screw of guide and guards lower to outlet is corresponding, Wiper blade is fixed on groove platform base by set bolt, there is recessed screw cap hole at the fixing hole place of Wiper blade, and the nut of set bolt is embedded in recessed screw cap hole, and the nut upper surface of set bolt is lower than the upper surface 5-8mm of Wiper blade.
The beneficial effects of the utility model are:
The upper surface of the utility model guide and guards under existing outlet adds Wiper blade, Wiper blade is that resin material makes, install can to eliminate guide and guards under existing outlet after Wiper blade cast part to the scuffing of belt steel surface, Wiper blade can adjust height at any time, avoid rolling thin gauge strip nose, the replacing of Wiper blade is simple and convenient simultaneously.The utility model structure is simple, respond well, convenient maintenance and replacement, effectively can avoid the scuffing of belt steel surface, improve the quality of products, be conducive to the exploitation of high-end product, simultaneously can when the thin slab product of rolling thickness≤2.0mm, avoid band steel nose phenomenon to occur, stop steel-fastening accident.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 be Wiper blade structural representation,
In figure, mark is as follows: outlet lower guide and guards 1, Wiper blade 2, groove platform 3, screw 4, fixing hole 5, screw cap hole 6.
Detailed description of the invention
The utility model improves guide and guards under existing outlet, add Wiper blade, to avoid the cast part exporting lower guide and guards to the scuffing of belt steel surface, and prevent from band steel nose phenomenon occurs when rolling thin slab product, stop steel-fastening accident.
Show in figure, under existing outlet, the upper surface of guide device 1 processes a groove platform 3 near roll side, and groove platform 3 is installed Wiper blade 2, and the upper plane of Wiper blade 2 is higher than the upper surface exporting lower guide and guards 1.
Show in figure, the bottom surface of the groove platform 3 of the lower guide device 1 of outlet has multiple screw 4, screw 4 is uniform in groove platform 3, Wiper blade 2 has the fixing hole 5 that the screw 4 of guide and guards 1 lower to outlet is corresponding, Wiper blade 2 is fixed on the bottom surface of groove platform 3 by fixing hole 5 and screw 4 by set bolt.
Show in figure, Wiper blade 2 is resin material making, Wiper blade 2 upper surface exceeds the upper surface 5-10mm of the lower guide and guards 1 of outlet, Wiper blade 2 has the chamfering of inclination respectively with the upper and lower of groove platform 3 link of the lower guide and guards 1 of outlet, and chamfering makes the junction rounding off of lower guide and guards 1 upper surface of the upper plane of Wiper blade 2 and outlet.Because Wiper blade 2 material is resin material, upper surface after Wiper blade 2 installation is higher than the upper surface of outlet guide device 1, can not contact with the upper surface of outlet guide device 1 with steel contacts with Wiper blade 2, the cast iron upper surface avoiding outlet guide device 1 scratches belt steel surface.
Show in figure, there is recessed screw cap hole 6 at fixing hole 5 place of Wiper blade 2, the nut of set bolt is embedded in recessed screw cap hole 6, and the nut upper surface of set bolt, lower than the upper surface 5-8mm of Wiper blade 2, is avoided colliding set bolt during band steel exports and caused heap steel.
The degree of depth of the groove platform 3 of an embodiment of the present utility model is 25mm, and length is 235mm, and width is 1570mm; The screw 4 of groove platform 3 bottom surface is 10, and the degree of depth of screw 4 is 35mm, and screw 4 is the screwed hole of Φ 16mm.Through statistics, an embodiment of the present utility model monthly can reduce scuffing imperfect tape steel about 200 tons, can reduce loss about 480000 yuan every year.
