Description
Technical field
The utility model relates to the Ferrous Metallurgy field, particularly a kind of rolling of sectional iron equipment.
Background technology
Adopting universal mill and universal rolling process to produce shaped steel (mainly be H shaped steel, also comprise the shaped steel of other sections, as rail, angle steel etc.) is known technology, and the general H shaped steel technological process of production is seen Fig. 1.
Existing universal rolling technology arrangement mode of producing H shaped steel mainly contains traditional tracking mode reversible rolling, semi-tandem rolling and complete three kinds of forms of tandem rolling (seeing " modern beam-and-rail production technology ", the Li Dengchao work):
One, traditional tracking mode reversible rolling
(1) 1 reciprocal tandem rolling of U-E unit (the technology arrangement sketch is seen Fig. 2)
The general shaped blank that adopts rolls out middle shaped blank by blooming mill and enters the reciprocal rolling odd-numbered pass of Ur-E unit after the heating furnace heating, go out finished product in rolling 1 passage of omnipotent finishing mill Uf at last, and Ur and Uf do not form continuous rolling relationship.
Wherein U is a universal mill, and Ur is a universal roughing mill, and E is an edging mill, and Uf is omnipotent finishing mill.
This arrangement form milling train quantity is few, simple to operate, but rolling pass is many, output is lower.
The reciprocal tandem rolling of (2) two U-E units (the technology arrangement sketch is seen Fig. 3)
Two reciprocal tandem rolling patterns of U-E unit, blank shuts out shaped blank through heating furnace heating back by blooming mill, and priority enters Ur-E roughing unit and Ur-E pre-finishing mill group is carried out reversible rolling again, at last by going out finished product after the rolling a time of omnipotent finishing mill Uf.
This kind arrangement is simple to operate, output is higher, causes plant area big but main rolling line is long, invests bigger.
Two, X-H rolling (the technology arrangement sketch is seen Fig. 4)
The X-H rolling is present widely used H shaped steel production technology, and milling train configuration is made up of one or two big mills (BD milling train) and three reversible tandem rolling units (Ur-E-Uf), as described in patent CN97126447.3.When the X-H method that this kind cloth deposits is produced H shaped steel, because last universal mill of tandem rolling unit had both been born the roughing task, bear the finish rolling task again, angle of sides was minimum when its omnipotent pass was used for roughing, cause roll wear very fast, amount of rolling is less, just need more renew roller to satisfy the required precision that omnipotent finishing mill rolls out finished product in the short period.
The arrangement form of X-H rolling and production technology: the hot base after heating furnace heating carries out split rolling method by one or two big mills (BD), roll after traversing stand is transferred to the universal rolling center line and carry out three tandem rolling units (Ur-E-Uf) reversible rolling, a back universal mill (Uf) serves as the dual rolling task of omnipotent roughing distortion and omnipotent finish rolling finished product in the operation of rolling.Behind some passage reversible rollings, roll out the finished product rolled piece by a back universal mill (Uf).
Because the back universal mill (Uf) in three tandem rolling units (Ur-E-Uf) had not only served as the role of universal roughing mill but also serve as the role of omnipotent finishing mill, in the whole process of X-H rolling mill practice, the shape on the H shaped steel edge of a wing produces the variation of X-H between two universal mills (Ur, Uf), make the roll wear of omnipotent finishing mill (Uf) very fast easily, amount of rolling of roll is little, makes that the roll life cycle is short in batch production process, and roll change is frequent, influence production efficiency, output is less.
In addition, when this kind technology arrangement was taken into account products such as producing rail, channel-section steel by the universal rolling method, in the universal changeable process, the back universal mill (Uf) among the Ur-E-Uf did not participate in the distortion of omnipotent roughing passage all the time, stays open state.A universal mill (Uf) is adjusted roll gap and to as-rolled condition rolled piece is carried out the finish rolling distortion and roll out the finished product rolled piece after when in the end a time is by tandem rolling unit (Ur-E-Uf), be only a time use in the end of a back universal mill (Uf), all passages of front all are in the empty state of crossing.Like this, the milling train utilization rate of three frame tandem rolling units (Ur-E-Uf) is not high, and bad to the production compatibility of other shaped steel such as rail and channel-section steel, production efficiency is lower, has greatly limited the release of universal mill production capacity.
Three, X-X-H rolling (the technology arrangement sketch is seen Fig. 5)
The X-X-H rolling is another kind of present widely used H shaped steel production technology, an omnipotent finishing mill (Uf) is set separately behind 3 roughing units (U1-E-U2), bear the omnipotent finish rolling distortion of last passage task specially, 3 roughing units (U1-E-U2) production capacity is discharged, as described in patent CN03816778.6.
The arrangement form of X-X-H rolling and production technology: the hot base of producing through heating furnace carries out split rolling method by one or two big mills (BD), become in the shaped blank behind the discontinuity surface at split rolling method, rolled piece is transferred to the universal rolling center line through traversing stand and carries out the distortion of three frame roughing units (U1-E-U2), after rolling by some passage universal changeables, last passage rolls out finished product section rolled piece by omnipotent finishing mill Uf.Before the distortion, rolled piece has been thrown off roughing unit (U1-E-U2) fully, does not form the tandem rolling deformation relationship in entering the Uf milling train.
This arranges that omnipotent finishing mill (Uf) is longer with the spacing of roughing unit (U1-E-U2), and length, plant area increase, integral body are invested higher to cause the workshop rolling line.And omnipotent finishing mill (Uf) makes rolled piece dispel the heat in transportation comparatively fast away from roughing unit (U1-E-U2), and temperature drop is bigger, and is unfavorable to the control of rolled piece temperature.Because temperature drop, this layout is not suitable for the little H shaped steel of production specification, thin wall H shaped steel and other shaped steel faster that dispels the heat.
Four, full tandem rolling (the technology arrangement sketch is seen Fig. 6)
Full tandem rolling arrangement form by many two roller roughing mills, many omnipotent in, finishing mill and edging mill form, its production characteristics are is a continuous rolling line from the blooming mill to the finisher, output is big, the efficient height, be fit to produce small dimension H shaped steel, but rolling line milling train quantity is many, invests bigger.
Produce the problem that arrangement exists based on above-mentioned H shaped steel, and in conjunction with current H shaped steel production technology and control development level, need to explore a kind of novel H shaped steel universal rolling production equipment and technology, low with various forms of roll lines and the existing production efficiency of rolling mill practice in the solution prior art, the equipment investment height, equipment capacity discharges problems such as deficiency, and make it not only be suitable for producing all size H shaped steel, also be fit to produce rail, I-steel, channel-section steel, angle steel, steel sheet pile, Yi shape steel, flat-bulb steel, L shaped steel, the shaped steel of various specifications sections such as crawler belt steel.
