Abstract
The invention relates to a guide device of a plum blossom square two-slitting pass system, comprising a rolling guide device; the rolling guide device is arranged on the outlet side of a K4 rolling mill; the rolling guide device comprises an upper guide wheel and a lower guide wheel; and the distance between the upper guide wheel and the lower guide wheel corresponds to the thickness of sectional material. The guide device of a plum blossom square two-slitting pass system in the invention adopts a method for arranging the rolling guide wheel on the outlet side of the K4 rolling mill, provides a certain clamping force and avoids continuous torsion when the K4 rolling mill outputs the sectional material so that the sectional material enters a K3 rolling mill according to design manner so as to avoid rolling fault caused by the continuous torsion of the sectional material.
Description
Technical field
The present invention relates to a kind of guide and guards, relate to the guide and guards of a kind of plum blossom square two slitting pass systems in particular, belong to the steel rolling process design field.
Background technology
In the rolling of sectional iron, guide and guards is installed in before and after the roll pass, helps rolled piece exactly, stably to get into and derive the device of pass by set direction and state, and it mainly act as: correctly rolled piece is imported roll pass; Guarantee rolled piece distortion stably in pass, and obtain desired geometry and size; Successfully with rolled piece by deriving in the pass, prevent curling round the roll; Control or pressure rolled piece reverse or flexural deformation, by certain direction motion.
In the design of guide and guards, decide the size and dimension of the rational working face of guide and guards according to workpiece measurement and shape, thereby make rolled piece can accurately, stably get into and derive roll pass.The guide and guard material chosen needs to select the guide and guard material according to pass shape and application site, requires to have good strength, rigidity, hardness and high temperature abrasion resistance, resistance to impact, anti-chilling and shock heating property, to improve service life.
The guide and guards type is divided into sliding guide, rolling guide and reverses guide and guard, selects according to being: a, selected pass schedule, and rolled piece cross dimensions and dimensional accuracy, steel grade and the surface quality passed through are selected; The outfit of the arrangement of b, milling train, frame form and quantity and auxiliary equipment; C, product situation, like range of product size, dimensional accuracy and concrete operating condition.
Production line of bar is when adopting two slit rolling process, and small dimension generally adopts plum blossom square groove system, and the typical characteristics of this system are exactly; The K5 passage adopts the plum blossom square groove, and K5 milling train outlet side adopts and reverses guide and guard, and the red steel utilization that the K5 milling train is come out is reversed and got into the K4 design of section of rolling mill after 45 is reversed in guide and guard; And red steel is after getting into the K4 milling train; Also have certain twisting resistance, cause red steel to come out from the K4 design of section of rolling mill after, continue to twist; Can not get into the K3 milling train according to design, cause rolling fault.
Summary of the invention
Technical problem to be solved by this invention is, overcomes the shortcoming of prior art, provides a kind of bar that makes to get into the K3 milling train according to design, avoids the guide and guards of the plum blossom square two slitting pass systems of rolling fault.
In order to solve above technical problem, the present invention provides the guide and guards of a kind of plum blossom square two slitting pass systems, comprises a rolling guide, and said rolling guide is arranged at K4 milling train outlet side.
The technical scheme that the present invention further limits is: said rolling guide comprises upper block and lower tumbler, and the distance between said upper block and the said lower tumbler is corresponding with the thickness of section bar.
Further, said device comprises that also one is arranged at the guide and guards that reverses of K5 milling train outlet side, and the said windup-degree that reverses guide and guards is 45 degree.
The invention has the beneficial effects as follows: the guide and guards of a kind of plum blossom square of the present invention two slitting pass systems; The outlet side that is employed in the K4 milling train is provided with the method for rolling guide; Certain chucking power is provided, weakens the follow-up twisting resistance that angle that the plum blossom square hole because of the K5 milling train reverses causes section bar to produce, thereby continue to reverse when avoiding K4 milling train output section bar; Make section bar get into the K3 milling train, avoid continuing to turn round the rolling fault that causes because of section bar according to design.

The specific embodiment
Embodiment 1
The guide and guards of a kind of plum blossom square two slitting pass systems that present embodiment provides comprises that a rolling guide 8 and reverses guide and guards.
The scheme of installation of plum blossom square two slitting pass system guide and guards is as shown in Figure 2, and rolling guide 6 is arranged at K4 milling train outlet side, and certain power of holding that adds is provided; The structural representation of rolling guide 6 is as shown in Figure 3, comprises upper block 7 and lower tumbler 8, and the distance between upper block 7 and the lower tumbler 8 is corresponding with the thickness of section bar.
Reverse guide and guards and be arranged at K5 milling train outlet side, windup-degree is 45 degree, and certain twisting resistance is provided.
Production line of bar is when adopting two slit rolling process; Small dimension generally adopts plum blossom square two slitting pass systems; Its structural representation is as shown in Figure 1, comprises K1 milling train 1, K2 milling train 2, K3 milling train 3, K4 milling train 4 and K5 milling train 5, and red steel 9 is when K5 milling train 5 comes out; Reverse 45 degree through the twisting resistance that reverses guide and guards and provide, get into the K4 milling train then; When the red steel 9 of entering K4 milling train comes out, get into rolling guide 6, the upper block 7 and the lower tumbler 8 of rolling guide 6 grasp red steel 9; Certain power of holding that adds is provided; Red steel 9 is stopped operating, get into K3 milling train 3, and get into K2 milling train 2 and K1 milling train 1 successively according to the mode that designs.
Except that the foregoing description, the present invention can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of requirement of the present invention.
