step S100.
Particularly, composition graphs 6, Fig. 7, in this step, rolled piece is after the plurality of roughing mills and the plurality of front mm finishing mill unit, enter this tube reducing unit to be rolled, wherein, this tube reducing unit comprises passage and final pass before finished product, leader pass type in passage before this finished product is set to single false ellipse pass, wherein, as shown in Figure 6, the pass radius R 4 of this leader pass type is set to 21.62 ~ 23.23mm, pass width B K4 is set to 38.26 ~ 40.0mm, pass height HK4 is set to 22.56 ~ 25.71mm, and roll gap S4 is set to 1.60 ~ 2.20mm, and the last groove in this final pass is set to double radius expansion circular arc circular hole, wherein the radius R 5 of this last groove is set to 14.20 ~ 14.28mm, pass width B K5 is set to 29.69 ~ 30.07mm, pass height HK5 is set to 28.20 ~ 28.56mm, and roll gap S5 is set to 1.40 ~ 2.00mm.
As shown in Figure 5, be the flow chart that the last groove in this step and leader pass type are designed.In last groove and the design of leader pass type, need the ability of equipment of considering, collars width to conditions such as the configuration requirements of pass.Particularly, as shown in Figure 5, when carrying out two kinds of hole type design, the flow process as shown in step S1 to S11 can be utilized, finally determining the hole type design parameter of last groove and leader pass type.
As previously mentioned, it has been generally acknowledged that in the industry and Traditional Textbooks, for leader pass type, pass axial ratio can not be too little, to ensure the normal operation of each equipment and final compact dimensions.
Such as, " Pass design " (Beijing: metallurgical industry publishing house, the 321st page in 2005) that Zhao Songjun, Tang Wenlin write is mentioned:
" non-universal process such as hole type design such as axial section such as grade.After axle hole type design completes, next will design centre pass such as axial section such as non-grade.Method for designing adopts known two passes such as axial section such as grade to ask the middle non-method waiting axial section pass, designs hereinafter referred to as flat hole.The design of flat hole has again two kinds of situations, and one is press from both sides a flat hole between two types such as axis hole such as grade, and namely twice shut out one and wait axial section; Another is that two axial sections such as grade press from both sides two flat holes, and namely three roads shut out one and wait axial section.
The target of flat hole design is: obtain a flat rolled piece, makes it in next pass, after rolling, to obtain waiting axial section rolled piece; To fixed rotating speed tandem mill, also require to ensure that each frame heap is established unprincipled connection, should ensure workpiece measurement, ensure that heap is established unprincipled connection again, the target of pursuit is not unique.Sometimes also to consider the axial ratio in flat hole, when flat hole axial ratio is greater than 2.8, axial ratio will be reduced as far as possible.And when axial ratio is less than 2, then should strengthen axial ratio as far as possible.”
In this book, (the 107th page) is mentioned further:
" the design of B leading oval pass
The formation parameter of oval groove is see showing 4-7, the height H of its pass
kdetermine by minimum round steel diameter d, its width dimensions B
kdetermine by maximum round steel diameter D, its B
kand H
kwith the relation of D and d as shown shown in 4-7.When just designing, preferably make H
kbe worth less, so that adjust and necessary amendment.
Its H of the 4-7 oval groove size that declines
kand B
kwith the relation of D and d
”
And in the present invention for
specification wire rod, does not consider the commonality of oval groove, therefore, and D=d=28mm.According to above-mentioned instruction, after the empirical equation recommended parameter in table being brought into, the scope that can obtain the axial ratio of leader pass type is: 1.73 ~ 1.98, is specifically calculated as follows shown in table 1:
Table 1: the leader pass profile shaft utilizing textbook training centre to calculate compares scope
| BK4(28mm) | 1.38 | 1.78 |

For the leader pass type in the present invention, its pass width B K4 is 38.26 ~ 40.0mm, and pass height HK4 arranges 22.56 ~ 25.71mm, and therefore, the scope of pass axial ratio BK4/HK4 is 1.56 ~ 1.70.According to the instruction of textbook, this is less than the axial ratio scope usually considered in the industry, but the axial ratio scope utilizing the present invention to design, but can realize stable rolling, and ensure that the requirement of dimensional accuracy.And just because of the instruction of textbook and the usage of trade, do not attempt applicable limiting value be in the industry
the high-speed wire production line of specification wire rod, is applied to
on the manufacture of specification wire rod.The present invention designs the axial ratio of leader pass type, breaches industry routine, overcomes industry prejudice, and achieves beyond thought effect.
In embodiments of the present invention, preferably, described tube reducing unit is traditional duo mill, and before the finished product namely in tube reducing unit, passage and final pass are made up of one group of roller-way respectively, and before described finished product, passage and final pass all adopt
the collars of specification.As shown in Figure 8, for leader pass type is configured in the schematic diagram before finished product in passage on collars; Be illustrated in figure 9 last groove and be configured in schematic diagram in final pass on collars.As seen from Figure 8, because have employed less axial ratio design, therefore compared to the configuration in Fig. 3, the leader pass type in the present invention, can successfully be configured in
on the collars of specification.
In addition, in this step, taken into full account the commonality of roughing mills pass in rough rolling process, therefore, the pass in roughing mills still adopts original parameter.
step S200.
In this step, rolled piece is in the step s 100 after the rolling of tube reducing unit, and sky crosses this sizing unit.
In the step s 100, by the rolling in passage before finished product in tube reducing unit and final pass, transferring out dimensional accuracy is
the product of specification, therefore, when product is by sizing unit, only need sky to cross this sizing unit, namely sizing unit is not rolled process to product.In production practices, the accident that quick-fried collars occurs sizing unit is much higher than tube reducing unit, especially for leading oval pass design of the present invention, the Edge Distance ellipse pass edge configuring the collars of this oval groove is very little, therefore, if when being configured in sizing unit, be then easy to the risk causing collars to ftracture or burst.So the empty mistake of sizing unit, is not rolled process to product, the object done like this eliminates the risk of sizing unit generation collars cracking or explosion.Therefore, in the present invention, have selected and carry out last groove and the adjustment of leader pass type in tube reducing unit, when product is sent from tube reducing unit, its specification meets the requirements, and by sizing unit space-time mistake, to ensure that the safety of production process is carried out.
step S300.
In this step, rolled piece, after completing steps S200, is conveyed into this Laying head by this pinch roll and weaves silk lopping, to form final wire rod product, weave silk in knitting cycle at this, the raising speed speed of this tube reducing unit, this pinch roll and this Laying head afterbody is set to 1.14 ~ 1.15m/S
2, the overstepping coefficient (i.e. the ratio of Laying head speed and mill speed, the whether reasonable cast with directly affecting wire rod of this value setting) of this Laying head is set to 0.990 ~ 1.005, and the mill speed of this tube reducing unit is set to be not less than 8.0m/s.
When rolled piece is by after sizing unit, need to carry out above setting to the mill speed of tube reducing unit, this sizing unit and the raising speed speed of this Laying head afterbody, the overstepping coefficient of Laying head and tube reducing unit, with ensure Laying head can successfully by
the product of specification carries out operation of weaving silk, and coils process to complete smoothly.
