Abstract
The utility model discloses a finishing mill group, including finishing mill group in advance, being equipped with a water tank behind the finishing mill group in advance, be equipped with 8 finishing mills behind a water tank, be equipped with the 2nd water tank at 8 finishing mill rears, be equipped with 2 mini finishing mills at the 2nd water tank rear, be equipped with the 3rd water tank at mini finishing mill rear, be equipped with pinch roll, laying head and the steyr air -cooled line that rubs in proper order behind the 3rd water tank. According to the technical plan provided by the utility model, has a reasonable structure, adopt 2 mini finishing mills, size precision is better, 8 the frame adopts behind the finishing mill group the 2nd water tank to wear and gets into 2 mini finishing mills behind the water, 2 back mini finishing mills can be controlled and preceding rolling temperature is rolled, finished product comprehensive properties is better, can enough satisfy altitude wire rod round steel and reinforcing bar size precision with ribbing requirement, realize the stable performance, it reaches " 8+4 " finishing mill 112ms's requirement to enable rolling speed again, and the cost of mini finishing mill is lower and only need two, reducible investment, the cost is lowered.
Description
Technical field:
The utility model relates to a kind of mm finishing mill unit.
Background technology:
Metallurgy industry high speed wire rod rolling field, Application comparison widely mm finishing mill unit type has following several:
1,10 frame mm finishing mill unit.Typical case's type is the root 5 generation 10 frame finishing mill milling method that rubs, and there are Sha Gang, Hunan steel in typical producer.The shortcoming of this milling method is: 1, random round sortie, and dimensional accuracy is relatively poor; 2, due to the fireballing feature of high-speed wire rolling, during 10 frame finishing mill rolling, temperature raises higher, and when weaving silk, temperature is also higher, and it is relatively poor therefore to roll rear combination property.
2, " 8+4 " mm finishing mill unit is 8 frame mm finishing mill unit+4 frame reducing-sizing mill.Typical case's type is: the root that 1) rubs " 8+4 ", and it is the root six generation type that rubs, and typical producer is stone horizontal stroke, Hangzhou Steel Company, An Gang; 2) Da Nieli " 8+4 ", typical producer is blue or green steel, Xing Gang; 2) western mark " 8+4 ", Weifang steel mill of typical producer." 8+4 " mm finishing mill unit advantage: 1) adopt 4 frame reducing-sizing mill, dimensional accuracy is better; 2) enter 4 framves after adopting water tank to wear water after 8 frame mm finishing mill unit and subtract precision mill, can control rear 4 framves and subtract rolling temperature before precision mill, finished product combination property is better; 3) single pass can be realized; 4) realize speed-raising, " 8+4 " mill speed can reach 112m/s.Shortcoming: 1) 4 frame reducing sizing mill investments are comparatively large, are 3,000 ten thousand yuan; 2) have speed ratio in 256, often lost efficacy during gearshift, impact is produced.
Need one badly can meet wire rod round steel and Ribbed Bar dimension precision requirement, realize stable performance, a kind of mm finishing mill unit milling method of investment can be reduced again simultaneously.
Utility model content:
The utility model is in order to make up the deficiencies in the prior art, provide a kind of mm finishing mill unit, reasonable in design, wire rod round steel and Ribbed Bar dimension precision requirement can either be met, realize stable performance, mill speed can be made again to reach the requirement of " 8+4 " finishing mill 112m/s, can investment be reduced simultaneously, reduce costs, solve problems of the prior art.
The utility model for solving the problems of the technologies described above adopted technical scheme is:
A kind of mm finishing mill unit, comprise pre-finishing mill group, the first water cooling box is provided with after pre-finishing mill group, 8 frame finishing mills are provided with after the first water cooling box, the second water cooling box is provided with at 8 frame finishing mill rears, be provided with the mini finishing mill of 2 frame at the second water cooling box rear, be provided with the 3rd water cooling box at mini finishing mill rear, after the 3rd water cooling box, be provided with pinch roll, Laying head and Stanermo wind-cooling linear successively.
The utility model adopts such scheme, reasonable in design, adopt the mini finishing mill of 2 frame, dimensional accuracy is better, the mini finishing mill of 2 frame is entered after adopting the second water cooling box to wear water after 8 frame mm finishing mill unit, the mini finishing mill of rear 2 frame can be controlled and roll front rolling temperature, finished product combination property is better, wire rod round steel and Ribbed Bar dimension precision requirement can either be met, realize stable performance, mill speed can be made again to reach the requirement of " 8+4 " finishing mill 112m/s, and the cost of mini finishing mill is lower and only need two framves, can investment be greatly reduced, reduce costs.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
In figure, 1, pre-finishing mill group, the 2, first water cooling box, 3, finishing mill, the 4, second water cooling box, 5, mini finishing mill, the 6, the 3rd water cooling box, 7, pinch roll, 8, Laying head, 9, Stanermo wind-cooling linear.
Detailed description of the invention:
For clearly demonstrating the technical characterstic of this programme, below by detailed description of the invention, and in conjunction with its accompanying drawing, the utility model is elaborated.
As shown in Figure 1, a kind of mm finishing mill unit, comprise pre-finishing mill group 1, the first water cooling box 2 is provided with after pre-finishing mill group 1, after the first water cooling box 2, be provided with 8 frame finishing mills 3, be provided with the second water cooling box 4 at 8 frame finishing mill 3 rears, be provided with the mini finishing mill 5 of 2 frame at the second water cooling box 4 rear, be provided with the 3rd water cooling box 6 at mini finishing mill 5 rear, after the 3rd water cooling box 6, be provided with pinch roll 7, Laying head 8 and Stanermo wind-cooling linear 9 successively.
Steel enter finishing mill 3 steel temperature by entering the first water cooling box 2 water-cool control after the pre-finish rolling of pre-finishing mill group 1, then finishing mill 3 finish rolling is entered, entering the second water cooling box 4 after finish rolling controls into mini finishing mill 5 temperature, then by mini finishing mill 5, roll out size, round steel that performance meets standard-required or Ribbed Bar, enter the 3rd water cooling box 6 subsequently and carry out cooling control laying temperature, then pinch roll 7 pinches, weaves silk, and realizes the uniformity of Property & Structure eventually through Stanermo wind-cooling linear 9.
The round steel of all specifications and Ribbed Bar all will through the mini finishing mills 5 of 2 frame, and different size obtains by getting rid of finishing mill 3 sortie.Such as, production Φ 5.5mm size round steel is the process route adopted is pre-finish rolling 4 framves+finishing mill 8 frame+mini finishing mill 2 frame, and when producing Φ 7.0mm specification, getting rid of two frame finishing mills 3, the process route namely adopted is pre-finish rolling 4 framves+finishing mill 6 frame+mini finishing mill 2 frame.
The utility model does not describe part in detail, is the known technology of those skilled in the art of the present technique.
