Abstract
The utility model provides a high-speed wire rolling mill of phi6.0 III grade reinforcing steel bar. The utility model comprises a finery rolling mill group. The utility model is characterized in that the screw roller of the finished goods sortie of the finery rolling mill group is the hole-shaped screw roller of finished goods sortie of phi6.0mm series, the remaining sortie employs the hole-shaped roller of phi5.5mm series. The utility model is reasonable to deploy the roller, convenient to transform the kinds of processing product rapidly and the utility model can reduce the debugging waste products.
Description
Technical field
The utility model relates to metallurgical equipment, is a kind of high-speed rod-rolling mill of rolling φ 6.0III grade reinforcing steel specifically.
Background technology
High-speed line milling train mm finishing mill unit pass schedule generally is divided into φ 5.5mm, φ 6.0mm, three series of φ 6.5mm at present, and φ 5.5mm series generally comprises φ 5.5mm, φ 7mm, φ 9mm, φ 11mm; φ 6.0mm series generally comprises φ 6.0mm, φ 7.5mm, φ 9.5mm, φ 12mm, φ 12.5mm; φ 6.5mm series generally comprises φ 6.5mm, φ 8mm, φ 8.5mm, φ 10mm, φ 10.5mm, φ 11.0mm, φ 13mm, φ 13.5mm.Along with the popularization of HRB400 hot-rolled reinforced bar, use the rolling φ 6.0mm of high-speed rod-rolling mill, φ 8.0mm, φ 10.0mm hot rolled ribbed steel bar to become a kind of trend.Each high line manufacturer product structure generally based on the drawing of φ 5.5mm series and φ 6.5mm series with material and construction timber, generally do not adopt φ 6.0mm produced in series.Like this, when customer requirements φ 6.0III grade reinforcing steel, just need the corresponding technological equipment of configuration separately, when rolling this kind, no matter change from φ 5.5mm series or from φ 6.5mm series, circular hole sortie roll in the finishing mill all needs to change, the semi-finished product size of finish rolling inlet needs to adjust, examination is rolled and is easily caused waste product in the process, need to convert to other series and this kind is rolling after intact, the single variety conversion and adjust before and after just need two hours, and cause the debugging waste product many, influence technical target of the product, increased processing cost.
Summary of the invention
The utility model is on the basis that overcomes the prior art shortcoming, and a kind of high-speed rod-rolling mill of rolling φ 6.0III grade reinforcing steel is provided, and its roll configuration is reasonable, is convenient to change fast processing variety, reduces the debugging waste product.
The purpose of this utility model realizes by the following technical solutions: a kind of high-speed rod-rolling mill of rolling φ 6.0III grade reinforcing steel, comprise mm finishing mill unit, the roller for screw thread that it is characterized in that described mm finishing mill unit finished product sortie is the roller for screw thread of φ 6.0mm series finished product sortie pass, and all the other sorties adopt the roll of φ 5.5mm series pass.
Described mm finishing mill unit is 10 sortie rolls, the top first breaker roll A1 pass size: high 11mm, wide 25.5mm, the second breaker roll A2 pass size: high 13.36mm, wide 14.32mm, the 3rd breaker roll A3 pass size: high 9mm, wide 14.32mm, four pairs of rollers A4 pass size: high 13.75mm, wide 11.88mm, the 5th breaker roll A5 pass size: high 6.76mm, wide 16.65mm, the 6th breaker roll A6 pass size: high 9.21mm, wide 9.33mm, the 7th breaker roll A7 pass size: high 5.2mm, wide 13.56mm, the 8th breaker roll A8 pass size: high 7.19mm, wide 7.29mm, the 9th breaker roll A9 pass size: high 4.4mm, wide 10.24mm, the tenth pair is the roller for screw thread B10 of finished product sortie, its pass size: the high 5.7m of internal diameter, the high 0.9mm of cross rib.
The utility model compared with prior art has many advantages and good effect:
1, the utility model is when the rolling φ 6.0mm series of needs III grade reinforcing steel, and mm finishing mill unit is except that the finished product sortie is changed roller for screw thread, and all the other sorties adopt the roll of φ 5.5mm series pass.Change the same of roll to each sortie semi-finished product fine setting in last operation unit semi-finished product size and the mm finishing mill unit, can be rolling smoothly.Reduced the time of changing between the kind series, former Technology Need 2 hours now only needs half an hour, produces this kind at every turn and saves 1.5 hours.
2, reduced the debugging waste product, originally needed to change many sorties roll, needed the roll change of a large amount of manpower organizations, and all need to reset the roll gap adjustment after each sortie roll change, caused rolling waste product many, the utility model has solved the many problems of debugging waste product.
3, realized that the minus deviation of φ 6.0III grade reinforcing steel is rolling, original technology is produced φ 6.0III grade reinforcing steel internal diameter, vertical rib height etc. in the upper limit, after adopting the utility model technology, internal diameter, vertical rib height have made things convenient for and have rolled back straightening and user's use generally at lower limit.
Description of drawings
Fig. 1 is the utility model finishing mill roll arrangement architecture figure.
The specific embodiment
Referring to Fig. 1, a kind of high-speed rod-rolling mill of rolling φ 6.0III grade reinforcing steel comprises mm finishing mill unit, and the roller for screw thread of mm finishing mill unit finished product sortie is the roller for screw thread of φ 6.0mm series finished product sortie pass, and all the other sorties adopt the roll of φ 5.5mm series pass.
Described mm finishing mill unit is 10 sortie rolls, the top first breaker roll A1 pass size: high 11mm, wide 25.5mm, the second breaker roll A2 pass size: high 13.36mm, wide 14.32mm, the 3rd breaker roll A3 pass size: high 9mm, wide 14.32mm, four pairs of rollers A4 pass size: high 13.75mm, wide 11.88mm, the 5th breaker roll A5 pass size: high 6.76mm, wide 16.65mm, the 6th breaker roll A6 pass size: high 9.21mm, wide 9.33mm, the 7th breaker roll A7 pass size: high 5.2mm, wide 13.56mm, the 8th breaker roll A8 pass size: high 7.19mm, wide 7.29mm, the 9th breaker roll A9 pass size: high 4.4mm, wide 10.24mm, the tenth pair is the roller for screw thread B10 of φ 6.0mm series finished product sortie, its pass size: the high 5.7m of internal diameter, the high 0.9mm of cross rib.
